FOREWARD

This study of the characteristics of manufactured hydroelectric

turbine equipment in the form of experience curves is presented to make

available information and experience that can be used in planning and

preliminary design of hydropower developments. It is intended to

supplement material already available for the more conventional hydrau­

lic turbines and therefore concentrates on information about low-head

type turbines. In the tradition of the Idaho Water and Energy

Resources Research Institute the report has been prepared to meet a

need and desire of government agencies and practicing professional

engineers involved in hydropower engineering.

ABSTRACT

This report contains the research findings of an extensive inves-

tigation of characteristics of over 300 low-head hydraulic turbines

that have been manufactured all over the world. These results are

presented in the form of experience curves and regression equations

relating the traditional turbines constants of specific speed, speed

ratio, unit power, and cavitation coefficient to such parameters as

rated head, rated discharge, rated power output, runner speed, and

runner diameter. Additional information on the characteristic dimen-

sion of the water passages is also presented. Traditional methods of

estimating turbine diameter and turbine speed have been checked with

actual practice and new simplified methods for estimating turbine dia-

meter and turbine speed have been proposed and verified.

A comparison has been made as to how well the draft tube exit

velocities on manufactured units are complying with recommended limits.

Rather limited success was obtained in characterizing the turbine

setting parameter and its relation to the specific speed. Excellent

comparisons were possible with published regression relations and

experience curves of conventional reaction turbines.

SUMMARY

This report presents information on experience curves and empiri­

cal relations useful in the preliminary planning of hydroelectric

power plants and their components based on actual manufactured and

operating units. The objectives of the study were to develop up-to­

date relations for low-head hydropower turbines giving (1) relations of

specific speed to design head, (2) relations of turbine runner diameter

to design head, rotational speed, and velocity ratio, (3) draft head

relations to specific speed and cavitation coefficient and (4) empiri­

cal relations of physical dimenions of flow passage dimensions of in­

take and draft tube areas to the turbine runner diameter.

Data for making the study were obtained by personal contact of the

authors in visits to over twelve manufacturers of turbines, by careful

review of existing technical literature, and by extensive correspon­

dence with over thirty manufacturers of hydroelectric turbines. A

careful assessment was also made of the literature on simulitude laws

and turbine constants that have been extensively used in the hydraulic

machinery field. Much reference and comparison have been made to the

U.S. Bureau of Reclamation Monograph No. 20 which has wide acceptance

and use in the planning and feasibility field by both public agency

engineers and by consulting engineers. Contact with over 200 different

consulting engineers by Professor Warnick has likewise been used as a

basis for judging and determining the approaches that are currently

used in professional practice. The ultimate goal of the study has been

to present useful procedures that can be authoritatively accepted by

the engineering profession and provide for a more uniform and

consistent preliminary selection of hydraulic turbines.

xii

The basic approach of the analytical portion of the study has been

to make regression analyses of the data collected on various turbine

characteristics used in hydropower planning. The regression approach

used was that of relating one independent parameter to a dependent

parameter, or to two parameters expressed as a single ratio. The curve

fitting utilized a logarithmic eqyation of the form:

log y = log A + m Log X.

Sets of data were analysed on a computer system known as Statistical

Analysis System (SAS).

The study centered on three types of turbines, (1) the bulb type

units, (2) the tubular type units, and (3) the cross-flow units (See

Figures 1 and 2). The results are presented in four distinct contribu­

tions: (1) Experience curves and regression equations were developed

for relating specific speed to rated head and similar regression equa­

tions were developed between the various standard turbine constants .

(see Tables 2, 3 and 4), (2) Relations were developed for determining a

cavitation coefficient that is used in choosing the turbine setting

(see Table 5), (3) Experience curves were developed for estimating

water passage dimensions and referencing those dimensions to the nomin­

al diameter of the turbine (see Figures 48 to 69), and (4) speed and

diameter selection procedures were assessed and compared with published

information on propeller turbines and new procedures developed for

making speed and diameter selection at the feasibility staqe of

planning.

The new selection procedures are presented in the form of noma­

graphs and comparative experience curves beginning with Figure 71 and

continuing to Figure 77. Sample calculations on how to apply the

xiii

experience curves are presented in Appendix 2. The conclusion is made

that these procedures are simpler and more direct than conventional

procedures now in use and appear to offer more consistent results. The

compilation of data on manufactured low-head turbines should offer an

excellent reference in itself for designers and planners to use in

preliminary design and feasibility studies.

Because this study applied to only low-head turbines and also

because new data on manufactured units are now available on convention­

al Kaplan, Francis and Pelton type turbines, it is recommended that the

new methodology developed on this study be used to update experience

curves and selection procedures for those types of turbines used in

higher head applications.

INTRODUCTION

In planning and design of hydroelectric plants much advantage is

gained by utilizing the experience gained from the various installa­

tions that have already been made. Publications like Engineering Mono­

graph No. 20 of the U.S. Bureau of Reclamation (1976) entitled,

"Selecting Hydraulic Reaction Turbines" have been developed for this

purpose. Records of experience have been analysed and various exper­

ience curves and empirical equations developed that provide a conven­

ient way to proceed in plannin9 for new hydropower developments.

Experience curves provide a way of making visual comparison easily and

with engineering judgement help the engineer in proceeding through the

complex task of planning and designing a hydropower development. These

do not substitute for the design selection that a turbine manufacturer

must make to proceed to final design. Experience curves however, do

provide the planning engineer with useful information to proceed with

feasibility and preliminary design studies.

Modern low-head hydroelectric turbines such as tubular turbines,

bulb type installations, and cross-flow turbines have now been in

production long enough to provide enough operating units from which

experience curves can be generated. The work of de Siervo and de Leva

(1976 and 1977) and de Siervo and Lugaresi (1978) treating conventional

Francis turbines, vertical Kaplan turbines, and Pelton turbines did not

consider the more modern low-head type turbines, neither did the

Engineering Monograph No. 20.

OBJECTIVE

The objective of this report is to provide experience curves and

practical empirical equations useful in planning and preliminary design

1

of hydroelectric developments for modern low-head type turbines. Spec­

ifically, to provide information on bulb type turbines, tubular type

turbines, and cross-flow turbines that have been manufactured in the

past thirty years. Particular relationships to be developed would

provide information on the following:

1. Specific speed relation to design head.

2. Turbine runner diameter relation to design head, rotational

speed, and velocity ratio.

3. Draft head relation to specific speed and cavitation coeffi­

cient.

4. Physical dimensions of flow passages (intake and draft tube)

relations to turbine runner diameter.

EXPERIENCE CURVES AND TURBINE CONSTANTS

Historically a series of turbine constants have been developed by

using similarity laws of hydraulics and fundamental hydraulic equations

to characterize the performance of hydraulic turbines. Mathematical

development of the various constants is covered in texts by Barrows

{1927), Doland (1954), Csanady {1964), Warnick (in press), and in an

M.S. thesis by Kpordze (1982). A worthwhile discussion on different

expressions for turbine constants is presented by Barr {1966). Recent­

ly international manufacturers have suggested an approach that reports

the various constants in dimensionless form (Allis Chalmers, no date).

Table 1 presents expressions for different forms of the various turbine

constants in use and the new dimensionless system of expressing the

turbine constants. This table contains a list of terms used in the

report along with appropriate units in which the terms are expressed.

The American system reports the constants in units of power output as

2

horsepower, diameter of runner in inches, turbine discharge in

ft3fsec, head in feet, and rotational speed in rpm. The European

system reports the constants in units of power output in kilowatts,

diameter of runner in millimeters, turbine discharge in cubic meters

per second, head in meters, and rotational speed in rpm. The European

system has been used throughout this report because so much of the

manufacturer's literature and experience curves that have been reported

have been published in the European system. Conversions and relation­

ships between the different forms of the turbine constants are provided

in Table 1 and in an example in the Appendix demonstrating the use of

the conversions.

Manufacturers who have worked with these constants and model tests

have further utilized the' constants to develop multiparameter relations

termed ''Hill Curves." These hill curves are proprietary information

and therefore are not available to practicing engineers for use in

selection and design. In practice many engineering firms develop their

own experience curves and once developed the curves are made proprie­

tary information of the firm. In this effort the experience curves and

empirical equations are being proposed as a way to achieve more consis­

tency in the planning studies and to provide a better and more uniform

base for proceeding with engineering design. In a sense it does pro­

vide a check as to the recommendations and quotations of performance

that are put forth by the manufacturers who may be asked to bid on and

supply hydraulic turbines.

The types of turbines studied are of two general types, reaction

turbines and impulse turbines. Three reaction type turbines were

studied: bulb type units, tubular type units and rim-generator units.

Typical representation of these units are shown in Figure 1. The

COLLECTION AND ORGANIZATION OF DATA

DATA COLLECTION

Collection of data was initiated first on this project when one of

the authors, Professor Warnick, contacted numerous turbine manufactur­

ers in connection with preparation of a new textbook on hydropower

engineering. This included reference lists and characteristics of tur­

bines manufactured by various turbine manufacturers. These personal

contacts have continued since that time and during the course of the

present research contract, several manufacturers were visited. A table

in the Appendix gives the list of manufacturers visited, a contact

name, and the address and the then active telephone number. On these

visits company literature particularly concerned with selection of tur­

bines was collected. A complete set of this manufacturer's information

has been assembled for the Bureau of Reclamation as a reference docu­

ment. Much of this document includes nomographs published by the com­

panies for use in selecting turbines and for providing preliminary data

on dimensions of standard turbines and water passages of the civil

works portion of hydropower installations.

The technical literature was searched for data on turbines and

representative of this is the technical articles like that of de Siervo

and de Leva (1977 and 1978) and also a listing of information prepared

by Cottillon (1977, 1979, and 1981).

Subsequent to the literature search and the initial personal

visits of Professor Warnick, considerable correspondence was carried on

to complete the collection of data. In some cases there were no

replies but in general good response was obtained in acquiring missing .

data and clarifying information that was obtained in personal contacts

or from published reference lists.

ORGANIZATION OF DATA

All information that was received was first checked to verify con-

sistency and identify appropriate measurement units. Transformation of

all units were made to make all units compatible with the European sys-

tern of reporting turbine constants. Data were then entered in a com-

puter file that would permit easy access for analysis. This informa-

tion included type of turbine, name of manufacturer, name of power sta-

tion, date of commissioning, rated head, rated flow, rate capacity per

unit, runner diameter, unit rotational or running speed and specific

water passage dimensions designated by letters of identification. A

complete list of all the data used or obtained during the study is

reproduced as tabular material in the Appendix 3.

Once a standardized file of the various data was prepared then

computer programs were developed to extract the data in various strati-

fications as to a particular type of turbine, a particular manufactur-

er, or a particular year of commissioning. These computer programs are

filed in the Appendix 4 to permit future researchers to proceed with

analyses of additional data.

METHODS OF ANALYSIS

The study basically entailed classifying and analysing different

sets of data from various manufacturers and data reported by the numer­

ous companies. Different statistical procedures were used in proceed­

ing with the analysis. One such statistical procedure is cluster

analysis.

The cluster analysis is a means of classifying observation (in

this case turbine characteristics) on the basis of similarity

(Anderberg, 1973). Cluster analysis in this research was used to group

the turbine data into periods of similar turbine design characteris­

tics. This method was considered a valid statistical technique for

classifying the turbine data into periods of similar turbine design

characteristics. In this study, the type of cluster analysis technique

used is similar to the weighted pair-group method used by Davis (Davis,

1973). The data base of four turbine characteristics on 221 bulb tur­

bines manufactured all over the world, was treated as a 4 x 221 matrix.

The four turbine characteristics used were: specific speed, rated

head, unit discharge and unit power. Using a computer, the 4 x 221

matrix was partitioned into a 4 x n1 and 4 x n2 submatrices based

on the date of commissioning of the turbines. Where n1 denotes num­

ber of bulb turbines put into service during the periods of time under

consideration and n2 denotes 221 - n1. The only restriction placed

on the value of n1 was that n1 be greater than 15 (n1 > 15}. The

analysis procedure was started from the earliest date among the turbine

commissioning dates, 1953 to the next date, say, 196a such that n1

was greater than 15. Then linear regression analysis was performed on

the resulting 4 x n1 and 4 x n2 matrices and the corresponding

8

correlation coefficients noted for each of the four groups of charac­

teristics. The value of n1 was then increased by increasing the per­

iod of analysis and the correlation coefficients recomputed and compar­

ed with the previously computed values. This process was repeated

until the resulting correlation coefficients were less than the nearest

previously computed values. Then the first period of analysis was

taken as the sample period corresponding to the highest value of corre­

lation coefficient. The procedure was repeated to determine the next

period of turbine design characteristics. The second trial period was

selected to include one year after the first period up to the year such

that n1 for the second time interval exceeded 15 turbine characteris­

tics. Two such periods identified for the 221 bulb turbines were:

1953 to 1965, constituting the first sample period, and 1966 to 1984,

the second sample period. The two above mentioned periods were then

used to group all the turbine characteristics throughout the rest of

the analysis to determine experience curves for low-head hydroelectric

tu-rbines. The only modifications made were in the cases where the

characteristics curves resulting from the regression analysis for the

two periods were so close as to justify representation by a single

regression curve or the number of turbine characteristics in each time

period were too few to justify the group classification. In all such

cases the period of analysis was taken to include 1953 to 1984.

STATISTICAL METHOD OF DATA ANALYSIS

The data used in developing the experience curves resulted from

the measurement of a number of variables and came from different

sources and were collected under a variety of conditions. In order to

describe the relationship existing between such variables, the standard

9

procedure is to formulate a statistical hypothesis setting forth the

explicit mathematical form of the relationship between the variables.

A common assumption is that the relationship between two variables, for

example, X and Y or the transformations of X and Y is linear. Having

assumed linearity, our objective then is to specify a rule by which the

11 best 11 straight line fitting X andY is to be determined. The 11 line of

best fit 11 is said to be that which minimizes the sum of the squared

deviations of the points of the graph from the points of the straight

line (with distances measured vertically). The general method of find­

ing equations for approximating curves which fit given sets of data

points plotted on a rectangular coordinate is known as curve fitting.

One of the main purposes of curve fitting is regression which is the

process of estimating the variable Y (dependent variable) from the

variable X (independent variable). If Y is to be estimated from X by

means of some equation, the equation is called the regression curve of

Yon X. The degree of relationship between variables is known as

correlation. When only two variables are involved, the relationship is

called simple regression and simple correlation. When more than two

variables are involved, the relationship is known as multiple regres­

sion and multiple correlation (Spiegel, 1961) and (Pindyck and

Rubinfeld 1981). Sometimes it helps to plot the scatter diagrams in

terms of transformed variables. For example if Log Y leads to a

straight line, log Y = a + bX will be used as an equation for the

approximation curve. The type of equations used in this study are:

Linear regression: y = a + bX

Exponential curve fit: y = aebx

Power curve fit: y = axb

10

',

Logarithmic curve fit: Y = a + log X 10

Where a, b and e are constants.

The degree to which numerical data tend to spread about an average

value is called the variation or dispersion of the data. One of the

most common measures of dispersion is the standard deviation, s. The

standard deviation of a set of N numbers x1, x2,

by the expression:

s = ( ~ (x - x)2 I N)0.50 j=l j

• • • • • • • X j is defined

which is the root square mean deviation and x is the arithmetic mean.

In the graphical representation of the curve, if parallel lines to the

regression line of Y on X are constructed at respective vertical dis-

tances s, 2s, and 3s from the regression line, statistical theory

states that there would be included between these lines 68%, 95% and

99.7% of the sample points, respectively. This is true only if the

numbers of data points, N, is large enough. The symbols with the s,

2s, and 3s lines are referred to as one-, two-, and three standard

deviations respectively.

The measure of how well a straight line explains the relationship

between two variables X and Y is the correlation coefficient, r and it

is expressed as the square root of the ratio of the explained variation

to the total variation. ( E(Y - Y) 2 I L: (Y - Y) 2 )0·50 where Y is the

estimated value of Y from the regression equation and Y is the

arithemetic mean value. Values of r = 1 or r = -1 denote perfect

correlation. The above defined statistical concepts have been used in

the data analysis and were embodied in the computer system used in the

studies and plotting the resulting experience curves.

11

The data used in the analysis were screened to include only tur­

bines having complete information; those having incomplete information

or unusual operating characteristics were eliminated. The resulting

sets of data were analyzed using a computer system known as .. Statis­

tical Analysis System .. (SAS), developed by SAS Institute, Inc. of North

Carolina, USA. The above named group of programs was run on IBM

Virtual Machine Facility/370 (CMS). The SAS computer system is set up

to perform linear regression analysis, to plot data values and to print

out any desired input or computed values. In order to use the trans­

formed variable models, the data must be transformed and arranged in

the appropriate linear model form. The selection of turbine constants

used in the linear regression models was based on the turbine constants

currently used in practice and the type of information needed for pre­

liminary investigation or feasibility studies of hydroelectric pro­

jects.

Traditionally the turbine constants specific speed, Ns, and the

speed ratio, 0, are used to select the appropriate type of turbine and

with developed empirical equations estimates are made of turbine runner

diameter and turbine speed. These turbine constant terms of Ns and

0 are defined mathematically in Table 1 and procedures for using the

constants in preliminary design and feasibility studies are illustrated

in sample calculations in Appendix 2. Among the procedures illustrated

in the sample calculations is the method used in the U.S.B.R. Monograph

No. 20 for estimating turbine runner diameter and turbine speed. Other

turbine constants such as unit speed, unit power, and unit discharge,

that are used to report turbine test data were also calculated for the

manufactured units and analyses were made to develop regression

relations between the different constants and the basic parameters of

rated head, rated power output, rated discharge, turbine speed, and

turbine diameter.

In this study emphasis was directed toward relations of specific

speed to rated head, speed ratio to specific speed, and the relation of

these constants to actual runner diameter and actual runner speed the

same as was used in the approach defined in the U.S.S.R. Monograph No.

RESULTS

The results are presented in three main classifications and fur­

ther subdivided into subclassifications. The first classification pre­

sents results relating to characteristics of the turbines and the tur­

bine diameter in relation to parameters of rated head, rated discharge,

rated output, and rotational speed of the turbine. This treats rela­

tionships and interelationships concerned with the turbine constants,

specific speed, unit speed, unit power, velocity ratio, unit discharge,

and some new alternative ratios as parameters.

The second classification presents information on draft head,

suction head, specific speed, and cavitation coefficient. The third

classification is concerned with turbine constants and the characteris­

tic dimensions of the water passages of the civil works portions of the

hydropower installations. This includes relating dimensions of the

entrance works leading up to the turbine and dimensions of the draft

tube to the turbine constants.

Under each of these classifications subclassification information

is presented on the three different types of turbines: {l} bulb type

units, {2) tubular type units, and (3) cross-flow type units. Infor­

mation on rim-generator type units was insufficient to make any mean­

ingful analyses.

TURBINES CHARACTERISTICS

The most common experience curve is obtained by relating the spec­

ific speed, Ns, to the rated head, H. Cluster analyses was performed

and the data stratified according to the time of commissioning.

In many engineering offices and in some manufacturer's compari-

tions were developed for manufactured bulb type turbines as follows:

0 = 0.0540 Ns 0· 5478 (1953-1965) Eq.

Figure 10. Unit speed versus unit discharge for bulb turbines.

The graphical relations for these three regression equations are shown

in Figures 11, 12, and 13. In seeking a simplification for use of

experience curves it was recognized that relating diameter to the basic

well known parameters of rated head and rated power would be most use­

ful because in preliminary planning the parameters of rated head and

rated power are most generally estimated early in the planning of pro­

jects based on the physical elevation situation of the water and the

power available from the estimated flows. On this basis a new regres­

sion analysis was made relating turbine diameter to the ratio of P/H

where P is the rated power output and H is the design head or rated

head. Figure 14 presents for manufactured bulb type turbines the rela-

. tion between turbine diameter and the ratio of rated power to rated

head and the resulting regression equations are:

D = 0.2119(P/H)0· 4374

0 = 0.1826(P/H) 0· 4462

(1953-1965)

(1966-1984)

Eq. (24)

Eq. (25)

A similar new relation was developed relating turbine diameter to the

ratio of rated discharge, Q, to the operating speed, N. This relation­

ship is shown in Figure 15 and the resulting regression equation is:

D = 4.181 (Q/N) 0· 3175 Eq. (26)

This again recogniz~s that in early planning stages the rated discharge

is known from the hydrologic analysis of power or energy potential at a

site and the choices of operating speeds are rather limited because

there are a limited number of available synchronous speeds at which

bulb turbines can operate if directly connected to the generator.

(Q/N), Rated Discharge over Turbine Speed

Figure 15. Turbine diameter versus (Q/N) ratio for bulb turbines.

An additional regression was developed between the turbine speed

and the ratio of rated power to rated head and the resulting regression

equations are

N = 1810.648 (P/H)-0.4176 (1953 1965) Eq. (27)

N = 2152.857 (P/H)-0.4062 (1966 1984) Eq. (28)

Figure 16 presents the graphical representation of N vs P/H.

As a result of inspection of an Escher Wyss nomograph for standard

tubular turbines a regression relation ~as developed between turbine

speed and the ratio, /H7D. The regression equations for bulb turbines

for that relation between turbine speed, N, and the ratio /HID are as

follows:

N = 162.103 ( /ff/0) 0·8912

N = 169.119 ( IH/0)0· 9260

(1953-1965)

(1966-1984)

Figure 17 presents the graphical representation of N vs IH?D.

Eq. (29)

Eq. (30)

Table 2 summarizes all the regression relations that were devel­

oped for manufactured bulb type turbines. In the table are shown all

the equations that were developed, the regression correlation coeffi­

cient for each particular regression, the corresponding standard devia­

tion, the sample period and the number of different units used in

developing a particular relation.

In the Appendix an example is given showing how these turbine con­

stants and regression equations can be used to make a diameter selec­

tion utilizing the analysis system used in Monograph No. 20 of the U.S.

Bureau of Reclamation and parallel calculations show selection of tur­

bine diameter using newly developed experience curves involving dir­

ectly a P/H ratio and a Q/N ratio and the resulting regression equa-

tions. 33

Table 4 summarizes all the regression relations that were

standard deviation, and the number of different manufactured units used

in developing a particular relation.

TURBINE SETTING CHARACTERISTICS

It is common practice to relate a turbine constant known as the

cavitation coefficient or plant sigma to the specific speed for exper-

ience curves. The equation ·for the plant sigma is given as follows:

H - H - H a v s o=------ Eq. (59} H

where o = plant sigma, dimensionless

Ha = atmospheric pressure head in ft or meters

Hv = vupor pressure head at temperature of water issuing from

turbine in ft or meters

Hs = difference in elevation between m)nimum tailwater level

and the cavitation reference point at the outflow from the

turbine in ft or meters

H = net effective head in feet or meters

The term, Hs, is referred to as suction head and it has slightly

different designation depending on the type of turbine, the location of

the tailwater and the orientation of the turbine and turbine shaft. A

related term is, z, the draft head the difference in elevation between

the tailwater level and the centerline of the distributor or the cen-

terline of the turbine runner. Figure 45 shows diagramatically what

these two terms are for different types of reaction turbines having

different shaft orientations. Sometimes difficulty is experienced in

relating the plant sigma to other turbine characteristics because the

cavitation reference point is not always consistently defined. In this

study for the axial flow units which includes bulb type units, the

tubular type units, and the rim-generator units the cavitation refer-

ence point was taken as the highest point on the propeller blade above

the tailwater level. In the case of cross-flow turbines the pressure

in the runner zone is essentially atmospheric pressure and is therefore

not subject to cavitation. No turbine setting and plant sigma analysis

was done on the cross-flow turbines.

Figure 46 also presents a composite experience curve of the

obtained. The regression equation for this composite experience curve

is given by the following regression equation.

The correlation coefficient for this regression is not very high and it

shows that such an experience curve is not expected to be very reli-

able. Using a regression relation suggested by Khanna and Bansal

(1979) a relation was developed between plant sigma, a, and unit dis­

charge, Q. The regression equation developed for bulb turbines studied

on this project is:

As for bulb turbines the correlation coefficient for this composite

regression for tubular turbines is not very high and it shows that such

an experience curve is not expected to be very reliable.

The relation between sigma, a, and unit discharge, Qn, for

tubular turbines is given by the regression equation:

tics for tubular turbines is presented along with regression informa-

tion on bulb turbines in Table 5.

WATER PASSAGE CHARACTERISTICS

The water passages of low-head turbines are quite different from

conventional Francis and vertical shaft Kaplan propeller turbines and

as such the dimensioning of the water passages is different for differ-

ent types. Significant in feasibility and preliminary design are the

entrance dimensions, the draft tube outlet dimensions or area, the

maximum diameter of the water passage surrounding the turbine, the

total length from entrance to draft tube outlet, and the length from

the centerline of the turbine to entrance. These data are useful in

layout design of the civil works and power house arrangement planning

as well as helpful in cost estimating. In this study it was possible

to obtain only enough different sets of data on manufactured bulb type

units to make regression analyses and develop experience curves.

In seeking the water passage information it was found that most

turbine manufacturers prefer to consider the various dimensions pro-

prietary information so that this phase of the research had to be

scaled to what could be collected under public disclosure allowances.

83

In the manufacturer contacts it was possible in several cases to

get recommended dimensions related back to a common turbine parameter

such as turbine runner diameter. This information has been grouped and

organized to be useful for design and also compared with different

manufacturers performance data to provide representative dimensions

that can be related to plant capacities.

During the study several companies provided standardized selection

information that gives considerable detail on different sized units.

These water passage dimensions have been analysed and comparisons

between different company's unit made and where possible regression

studies were conducted. In general there was insufficient information

on the possible standardized units to develop experience curves.

Following the earlier pattern the specific information on water passage

dimensions is presented systematically according to different turbine

types, beginning with bulb type turbines.

Bulb Turbines

To present the water passage information it is necessary to show

schematically the various water passage dimensions that were analysed.

Figure 48 shows a simplified dimensioning sketch with dimensions label­

ed with letters that were used in the regression analyses and the com­

parisons. All dimensions have been related back to the desi9n diameter

of the turbine runner as obtained from the manufacturer. Since the

rated power is frequently an estimated value that is obtained early in

the feasibility study, water passage dimensions were also related to

rated power, P, and in some cases relations were sought with the rated

discharge, Q. In certain cases like the entrance to the turbine and

the exit from the draft tube the dimensions actually represent areas.

factured turbines were designated for commissioning, and the number of

different units used in developing a particular relation.

Tubular Turbines

Insufficient manufacturer•s data on actual manufactured turbines

were obtained to develop a useful regression equation for tubular

turbines water passage dimension. However, information was obtained

from certain manufacturers that gave recommended relations between the

sizes of certain water passage locations and the diameters of the

propeller runners. Figure 64 gives the recommendations for preliminary

Figure 64 also gives similar recommendations for preliminary sizing of

tubular turbines as suggested by Escher-Wyss of Switzerland.

A few of the manufacturers have developed recommended dimensions

for standard tubular turbines and published these data. Copies of the

information was furnished to the U.S. Bureau of Reclamation. Table 7

gives the standard tubular recommendation information and the source

from which the data were taken. These respective tables of recommended

dimensions were used to develop experience curves relating water pass-

age dimensions for tubular turbines to the propeller diameter. The

information presented in each company's tubular material apparently was

developed by the companies from their own model tests. The water pass-

age dimensions Ae, Ao, L1, and M used in the regression equations

are defined on Figure 65.

Figure 66 presents the relation between turbine entrance area,

Ae, and the turbine diameter, 0, and the resulting regression equa-

tion for tubular turbines is given as:

ANALYSIS AND USE OF RESULTS

The basic purpose of the research was to present simplified

methods for making preliminary selection of diameter and speed of low­

head turbines. A review of the work of Lindestrom (no date) of the

Swedish firm KMW presented a simplified nomograph for making that

selection. Figure 70 is a reproduction of the nomograph from

Lindestron (no date) for bulb turbines. Because the basic parameters

used were the same as those involved in the regression developed as

Eqs. (24) and {25) that is D = F {P/H), it was simple to construct a

similar nomograph from the regression equations developed on this pro-

ject. To check the validity of the KMW nomograph, the basic data for

bulb turbines manufactured by only KMW were subjected to a seperate

regression analysis the same as with all the bulb units. Table 9

presents the summary of the results of that special regression analysis

of KMW manufactured bulb units, giving the empirical equation, correla-

tion coefficient, standard deviation, sample period and the number of

units involved. A check of using the regression from the authors

special study confirmed the individual curves of the nomograph that had

been presented in Lindestrom (no date).

Figure 71 gives a nomograph for estimating bulb turbine diameters

based on rated head and rated power output. This nomograph was devel­

oped by using the regression equation, Eq. 25. A similar nomograph for

tubular turbines is presented in Figure 72 which utilizes regression

equation, Eq. 41. The corresponding nomograph for cross-flow turbines

is presented in Figure 73 which utilizes regression equation, Eq. 57.

An estimation of turbine speed can be made in several ways. One

way is to use the same parameters of rated head and rated power output

as used for bulb turbines the regression equation, Eq. 27. Another

method is to use the estimated diameter as found from the nomograph

Figure 71 or Eq. 25 and substitute that in regression equation, Eq.

26. An additional approach is to take the estimated diameter as found

from nomograph Figure 71 or Eq. 25 and substitute that value of dia-

meter into the regression equation, Eq. 30.

The more conventional approach for estimating turbine diameter and

speed has been that explained in U.S.B.R. Monograph No. 20 and is to

first find a trial value of specific speed, Ns, from a curve like

Figure 3. Then proceed to find a trial speed, N', from the specific

speed equation.

A synchronous speed must then be chosen utilizing the relation. 120 X f Np =

where Np = number of generator poles

f = electrical frequency in Hz.

Eq. (89)

The number of poles, Np, must be in multiples of two or four, usually

in multiples of four. Once a synchronous speed is chosen then the

actual specific speed, Ns, is calculated using, Eq. 4. The next step

is to use the actual, Ns, in an empirical equation to determine the

speed ratio, 0. For bulb turbines this would utilize regression

equation, Eq. 18. For propeller units the U.S. Bureau of Reclamation

Monograph No. 20 (1976) gives the following:

0 = 0.0233 Ns 213 Eq. (90)

As a final step the estimated turbine diameter can be determined using

selected turbine speed, N, the rated head, H, and the empirically

determined value of speed ratio, 0, in the following form of the speed-

ratio equation: Ho.s

D = 84 . 58 0 -- E q . ( 91 ) N

This equation comes from the basic definition of speed ratio. To

illustrate the procedure for this selection process for estimating tur-

bine diameter and turbine speed sample calculations have been presented

in the Appendix. The sample calculations have been performed for a

manufactured unit at a plant in Europe known as Isawerk 3.

Additional comments are presented on the advantages of different

approaches to diameter estimation following a presentation of compar-

isons.

122

COMPARISONS

With the various different regression that were performed it is

informative to make a few simple comparisons. Figure 74 is a compari-

son of several different experience curves relating specific speed,

Ns, to the rated head, H, for different kinds of low-head turbines

studies on this project as well as results from other published stud-

ies. The curves include two experience curves taken from the Figure 11

of the U.S. Bureau of Reclamation Monograph No. 20 (1976), the work of

de Siervo and de Leva (1977), the work of Lindestrom (no·date), and the

experience curves for the three different types of turbines (bulb,

tubular, and cross-flow turbines) studied on this project. Table 10

summarizes the information on the specific speed versus rated head

relations for low-head type turbines.

Because the U.S. Bureau of Reclamation Monograph 20 gives an

empirical equation relating the speed ratio, 0, to the specific speed,

Ns, that is used in preliminary speed and diameter selection a com­

parison was made with similar relations developed in this study.

Figure 75 shows this comparison. The data gathered on this project

were used to develop a regression equation with the same exponential

power of the Ns as was reported in the U.S.S.R. Monograph 20, that

is, Ns raised to two thirds power. The regression equations for the

different types of turbines developed are indicated below:

0 = 0.6374 + 0 164 N 213 (Bulb) Eq. . s

0 = 0.2036 + 0 0227 N 213 (Tubular) Eq. . s

0 = 0.4356 + 0 0026 N 213 (Cross-flow) Eq. . s

It should be noted that the plotting of Equation 19 developed by

Kpordze-Warnick for bulb turbines shows a slight deviation from

Figure 75. Comparison of experience curves of speed ratio versus specific speed for different types of axial-flow turbines.

Equation 92 at the two extremities of the plotted lines. The Kpordze­

Warnick form of the relationship plots as a straight line on logarith­

mic paper and has Ns raised to the exponential power value of 0.4605.

The correlation coefficient is slightly better for the Kpordze-Warnick

form than with the Ns raised to the two-thirds power. There is

essentially the same margin of error in the two forms of the equation

as indicated by the values of the standard deviation found in the

development of the two equations.

The plotting of Equation 38 developed by Kpordze-Warnick for tubu­

lar turbine and the Equation 93 utilizing Ns raised to the two thirds

power for tubular turbine are so nearly the same it is not possible to

distinguish between the two lines on the scale shown in Figure 75.

Brief trial comparisons of using these different experience curves

shown in Figure 75 would indicate that in the middle range of situa­

tions calling for turbine selection for Ns in the range from 700 to

900, reasonably similar results can be expected using de Siervo empiri­

cal relations, the U.S.B.R. empirical equation for propeller units, and

the empirical equations for bulb turbine units developed in this study.

In ranges of Ns values outside the range 700 to 900 traditional

empirical equations should not give good results.

An additional comparison was made of the regression analysis

involving the plant sigma, a, and the specific speed, Ns. Figure 76

gives the comparison that includes a versus Ns for bulb turbines, a

versus Ns for tubular turbines and a reproduction of a KMW relation

between a versus Ns for all turbines manufactured by that company,

Lindestrom (no date). Plotted on Figure 76 is the empirical equation

for a versus Ns as taken from U.S. Bureau of Reclamation Monograph

20 (1976).

The comparison shown in Figure 76 includes a stratification of

tubular turbine data (Curves A and Curves B) of those tubular turbine

manufactured outside the United States. The o versus Ns curve for

just the units manufactured outside the United States (Curve A) does

show that lower values of 0 will be predicted for corresponding values

of Ns. Curve B is for all tubular turbines studied including Ameri­

can manufactured units and some European units and a few Japanese

units. This indicates that if units are submerged below tailwater (as

they usually are for bulb and tubular turbines) greater submergence has

been required on American manufactured tubular turbines. Likewise, it

would indicate that the experience curves show bulb turbines have been

submerged less than tubular units.

Review of an article by Khanna and Bansal (1979) revealed an

experience curve relating plant sigma, o, to the unit discharge,·

Q11, for bulb turbines. With the regression analyses performed on

this project involving the plant sigma, o, and the unit discharge,

Q11, for bulb turbines, Eq. 66 and for tubular turbines Eq. 68 it

was possible to make a comparison. The comparison is shown in Figure

77.

The equation listed for the reproduction of experience curves from

Khanna and Bansal (1979) were developed using curve fitting by the

authors of this report. The work of Khanna and Bansal (1979) also

included an experience curve for Kaplan turbines. It has also been

reproduced on Figure 77 for comparison purposes.

An analysis for comparative purposes was made of the characteris­

tics of the draft tube exit velocities of 54 bulb units for which data

were available. Purdy (1979) reported that the exit velocity should

Table 11 shows how exit velocity compares with the value of 0.8 IH for

each turbine. The recommendation of Purdy was based on the fact that

if higher velocities were permitted considerable power was lost but not

often considered in the real overall performance. This comparison

shows that many of the manufactured turbines have exit velocities that

exceed the Purdy recommendations.

To assess the difference that might be expected in using different

methods of estimating turbine diameter and turbine speed a comparative

study was made of eight hydro power plants that had data on rated head,

rated discharge, and rated power output. The data on the eight plants

also included the actual manufactured diameter and actual turbine speed

used at each plant. Five different methods were used in the assess­

ment: (1) using the traditional approach as presented in U.S. Bureau of

Reclamation Monograph No. 20 for propeller turbines, (2) using the

regression equations developed by de Siervo and de Leva (1977 and 1978)

for Kaplan turbines, (3) using the nomograph from Lindestrom (no date),

(4) using the regression equation developed in the special study of KMW

manufactured units, and (5) using the regression relations developed in

this study using all the bulb turbines. Sample calculations showing

how the comparative numerical values for turbine diameter, D, and tur­

bine speed, N, were obtained are presented in the Appendix 2. Table 12

presents the results of the assessment.

The results would indicate that the simplified selection procedures

suggested by the authors of this report have several advantages. The

procedures are simple and require only two parameters, rated head and

rated power, that are normally available early in feasibility studies.

regression equations used in the selection prodecures is revealing.

Table 13 shows the various regression relations used and the value of

the correlation coefficient for each relation for the various different

kinds of low-head turbines. This shows that for the functions

involving D = F(P/H), and N = F(IHI) the regression correlation D

coefficients are higher than the functions involving Ns and 0. The

author's suggested approach to estimation of turbine diameter and tur-

bine speed appears to give greater accuracy and consistency.

CONCLUSIONS AND RECOMMENDATIONS

This study of experience curves has collected data on rated head,

rated discharge, rated power output, turbine speed, and turbine dia-

meter on more than 300 manufactured low-head turbines produced through-

out the world since 1953. Additional information on turbine water

passage dimensions and on particular characteristic sizes of turbine

intakes and draft tube exits has been compiled. The data have been

subjected to an intensive mathematical analysis by regression techni-

ques in an attempt to develop useful predictive methods for feasibility

and preliminary design purposes. The following conclusions are made.

The information on rated head, rated discharge, rated power out­

put, turbine speed and turbine diameter along with water passage dimen­

sions has been catalogued in a convenient computer format (see Appendix

3). The catalogue in itself should be a valuable reference from which

comparisons could be made when choosing preliminary features of turbine

installations for a new hydro power sites.

A comprehensive collection of experience curves for the conven-

tional turbine constants and turbine selection approaches has been

developed for bulb turbines, tubular turbines and cross-flow turbines.

The experience curves have been developed using conventional hydro­

power terms and turbine constants that have been applied to Kaplan tur­

bines, Francis turbines and Pelton turbines of the impulse type. The

results have been presented in easy-to-use equation form and are also

presented graphically to show the scatter of the data in the various

relations that were developed.

The results of the study of cavitation characteristics of low-head

turbines using the relation between plant sigma, a, and specific

speed, Ns, did not show as good a correlation as expected. There is

considerable variation in the relation between plant sigma and specific

speed from company to company and the correlation coefficients of the

regression are not very high. Caution should be used in applying the

experience curves of plant sigma versus specific speed developed in

this study. Because the use of this cavitation coefficient in turbine

setting elevation determination is highly dependent on cost of excava­

tion for the draft tube this becomes a difficult item to make authori­

tative guidelines for preliminary design purposes.

The results of the study of dimensions of water passage, and their

relation to turbine diameter are reasonably good for the bulb turbines.

Insufficient data were obtained on tubular turbines to make regression

analysis of relations between turbine diameter and water passage dimen­

sions. However, the latest recommendation of manufacturers with regard

to sizing water passages has been catalogued and presented in a useful

form for tubular turbines.

A significant and very simplified procedure for estimating turbine

runner diameter and turbine speed has been developed. This new proced­

ure was tested and compared with the procedure presented in the

136

U.S.B.R. Monograph No. 20 and with other approaches. Results of the

comparison shown in Table 12 indicates that the new simplified proce-

dures give more consistent estimates of turbine diameter and speed than

other methods and are easier to apply using data that are readily

available early in the planning stage of a hydropower investigation. A

careful documentation of steps in the selection process for estimation

of turbine diameter and turbine speed has been presented in sample cal-

culations shown in Appendix 2.

Because these regression equations developed in this study are

from a much larger sampling of manufactured units that was used in

development of the empirical equations in U.S.B.R. Monograph No. 20 and I

because the study is for specific types of low-head turbines, the

empirical equations developed in this study should be relied on more

than using the older more traditional equations. It should always be

remembered that final design and confirmation of size of runner and

runner speed should be worked out with the individual manufacturers and

the· estimation developed from experience curves should be used as a

check on manufacturers recommendations.

In general good response from turbine manufacturers was obtained

but no data were obtained from Chinese and Indian manufacturers and

only limited data were obtained from Japanese firms.

Recommendations

The writers recommend that this information be incorporated in a

revised edition of the U.S. Bureau of Reclamation Monograph No. 20. To

make Monograph No. 20 most useful, the data on more conventional tur-

bines such as Pelton turbines, Frances turbines and vertical Kalpan

turbines should be updated and subjected to the same type of regression

analysis as was done in this study of low-head type turbines.

137

If desirable a nomograph for easy selection of each type of low­

head turbine could be developed similar to that given in the work of

Lindestrom (no date). This nomograph could include further development

of the turbine setting restraint as limited by the plant sigma. A

recommendation here would be to develop some kind of standardized safe­

ty factor that could be agreed to by a team of authorities. The result

could be developed as a family of curves of suction head superimposed

on an experience curve for selecting diameters given rated head and

rated power output. It is recommended that more careful appraisal be

made of the exit velocity from draft tubes in manufactured units of low­

head turbines to see if reductions in velocities could improve future

hydropower installations.

The new procedures developed for estimating of turbine runner dia­

meter and runner speed are recommended for use in preliminary design

and feasibility studies for low-head turbines because of the simplicity

and the evidence presented in this report of giving consistent results

when compared with other more involved procedures.

SAMPLE CALCULATIONS FOR TURBINE CONSTANTS CONVERSIONS

A series of sample calculations are presented using actual data

from the Rock Island power plant on the Columbia River. Different

SAMPLE CALCULATIONS FOR DETERMINING TURBINE DIAMETER

AND TURBINE SPEED BY DIFFERENT METHODS

These sample calculations are executed to illustrate different

methods of estimating preliminary values of turbine speed and turbine

runner diameter. The traditional method as put forth in the U.S.

Bureau of Reclamation Monograph No. 20 (1976) is compared with publish­

ed results of deSiervo, the work and methodology of Lindestrom of KMW

in Sweden and different approaches developed on this research project.

This illustrates the variability that can be obtained. Each method and

the appropriate equations require at least one empirical equation that

is based on experience curves based on performance of ~anufactured

units or from studies of model test data. Documentation as to where

each empirical equation came from is presented in these sample calcula­

tions.

determine a trial speed N1 by solving for N in above equation

N I = {4.5) 514 1273.7

r--1200 = 241.0

148

Recognizing Np = 6000/N

Where Np = number of poles at 50 Hz

Then Np = 6000/241 = 24.9 poles

Therefore the nearest multiple of four poles would be Np = 24
