WATER PIPE – TRANSIENT LOAD ANALYSIS.

CALCULATION OBJECTIVE Determine maximum and minimum transient pressure,

external forces acting on the flowing water in the straight pipe sections and selection of surge control devices for two pump trip and pump start with closed butterfly valve. Hydraulic transient loads, in the straight pipes between two nodes, due to pump trip, are also presented for approximate pipe stress analysis. The CW system is a standard configuration. Based on experience, the only significant transient concern is column separation after pump trip followed by column rejoining resulting in a potential large waterhammer surge pressure. I t is supposed that butterfly valves time closure is long enough not couse significant pressure surges.

CALCULATION METHOD The SURGE2000 program solves the basic equations of fluid

mechanics for the transient flow of an incompessible fluid in a pipe network. The “wave plan” approach is used.

1 ASSUMPTIONS Total Cooling Water Flow Rate is based on Condenser requirement of 57,200 usgpm, plus Heat Exchanger Flow Rate of 2,000 usgpm = Total Flow of 59,200 usgpm: x 1.05 SF = Total Rated Flow of 62,160 usgpm for two (2) Pumps in Parallel operation. Total Rated Flow / Pump = 31,080 usgpm. Wave Propagation is calculated for water without presence of even small quantities of air, which significantly reduce the wave propagation speed in the pipes. Pump Four Quadrant File is selected for specific speed 4409 (ID 5) which is nearest to the pump specific speed Ns = 4390 supplied by manufacturer. SURGE2000 program has 8 files based on experimental available data. The pump file is customized to the cooling water pump by the Rated Head, Rated Flow, Rated Speed and Inertia (corresponding specific speed 5460 not confirmed by manufacturer). Water cooling pumps have a non-reverse ratchet. SURGE2000 simulate (i) pump trip: the pump speed following loss of power is calculated using dynamic analysis including torque, inertia, etc. If the butterfly valve at the pump outlet does not close, pump turns into the turbine operation with reverse flow and speed of rotation – runaway. (ii) Program simulates pump shutdown, pump start up, pump shutdown followed by startup (table of rated) changing the speed of rotation – input: speed versus time. Really pump transient operating point and corresponding torque controls speed, as it is programmed in the case of pump trip. Analysis was complete as follows: • Pump trip with selected pump file ID 5 in the region of specific speed

between 4390 and 5460, which delivered a bit lower pressure at the condensers and pump outlets.

• Input table: pump speed versus time was selected to follow pump trip pressure drop, estimating the time when pump speed should be zero. Results of analysis is not enclosed into this report.

• Analysis was further continued with the selected input data table. Condenser is simulated by the equivalent pipe of the same length as 1 in pipes (total number 6,740), wave propagation speed, flow velocity and pressure drop. Valves simulate cooling tower sprsy nozels: pressure drop 2 ft at full Rated Flow.

3 SUMMARY Total Cooling Water Flow Rate is based on Condenser and Heat Exchanger Flow requirement of 62,160 usgpm for two (2) Pumps in Parallel operation. 3.1 Pump Trip Minimum calculated vacuum at the pump outlet and upper condenser inlet and outlet for the system without protecting devices (Air/Vacuum valves) is less than 10 ft of H2O (4.3 psi). Water column separation will nor occur. Therefore, surge mitigation devices are not necessary. 3.2 Pump Start When started, the Circulating Water Pumps compress the air .between the pump and butterfly valve.The air (compressed) vents to the amosfere through an orifice located on the pump discharge head.. Butterfly valve opening time is 60 sec and starts opening when the air is vented from the pump discharge head and discharge piping.

4 METHOD OF ANALYSIS 4.1 Introduction The hydraulic transient effects of pump trip will be investigated by computer simulation using the SURGE2000 software. The extent to which a pump trip may generate significant high or low pressures in the CW piping system is directly proportional to whether column separation can occur during shutdown and whether subsequent column rejoining can occur. The fluid response depends on the pump characteristics, the moment of inertia of the pump shaft and motor, the action of the butterfly valve and the system steady state hydraulic grade line and elevations. The computer simulation will model the interaction of these system components and effects to predict the transient pressures. The first step of this investigation is therefore to simulate the normal operation of the piping system with respect to head and flow. The steady state head vs. flow output is then used in the transient analysis module to simulate pump trip and pump startup. 4.2 Computer Program Used The SURGE2000 computer program is used for all simulations in this calculation. It is a commercially available microcomputer based software program qualified by S&W. 4.2.1 SURGE2000 The SURGE2000 computer program is a generalized commercially available hydraulic program which is used to perform both steady state and transient analyses of a piping network which may include pumps, reservoirs, air/vacuum valves, valves, bypass lines, etc. The SURGE2000 program uses the "wave plan method" with a finite difference approximation in both space and time in order to solve the governing partial differential equations. The spatial characteristics of the system are defined by the flow parameters that are ascribed to each node. One node is placed at each end of a pipe and the remainder is equally spaced along the pipe. Discretization of the flow problem with respect to time is governed by the integration time step which is usually very small. The Courant No limits the time step of the model as follows: AT ≤ min (∆xi/aI) [where: xi = nodal spacing for the pipe and ai = sonic velocity in the pipe}. The SURGE2000 cannot calculate unbalanced forces and hydraulic vibrations.

7 SUMMARY OF RESULTS / CONCLUSIONS The hydraulic transient analysis of the Big Hanaford Combined Cycle Plant cooling system was performed using the SURGE2000 computer program to determine if water column separation and water column rejoining with subsequent significant pressure surges can occur after pump trip. The results of the analysis show that water column separation and subsequent water column rejoining will not occur. Unbalanced axial forces on elbow pairs due to pump trip are not analyzed. The Circulating Water Pumps , when started, compress and vent the air between the pump and the butterfly valve to the atmosphere. Pressure waterhammer force on the butterfly valve has been calculated. Three hydraulic cases are simulated as follows: Case 0 – Two Pumps Trip and Selection of Pump File for Transient Analysis. Case 1 - Pump operation followed by 2-pump trip (to full runaway of the pumps – pumps without

non revese ratchets). Case 2 - Pump operation followed by 2-pump shutdown – pump speed reduced from 710 rpm to 0

rpm in 5 seconds (pump with non reverse ratchet). Case 3 - Pump startup and air vent through 2 in pipe with the outlet orifice 1.25 in. Case Input File Output file Date/Time Printed Input / Output Results

The steady state (hydraulic grade line vs. flow) results and one pump operation were obtained using the SURGE2000 steady state module and show very good agreement with the steady state hydraulic calculation presented in Calculating Water Pumps (70-P-04 A/B/C), Estimated Flow and Total Dynamic Head Requirements, No. 11458-000-09-CW-15. The steady state hydraulic results are automatically input into the SURGE2000 transient module to simulate pump trip.

7.1 Case 0. Two Pumps Trip and Selection of Pump File for Transient Analysis This case is simulated for 30 seconds to see the effect of 2 pumps operation followed by 2-pump trip. A review of the nodes AV-H (condenser outlet upper flange at elevation 263.1 ft), Pump-1 and Pump-2 (pump outlet pipe at elevation 261 ft), see Figs. 1, 2, and 3, show that the difference is very small so any of these two pump files can be used for further calculations. Pump file ID 5 was selected. 7.2 Case 1. Two pump Trip This case is simulated for 30 seconds to see the effect of 2 pumps operation followed by 2-pump trip. A review of the node AV-H (condenser outlet upper flange at elevation 263.1 ft) pressure plot in Fig. 1 and Table 4 reveals that the head at this node drops to pressure –8.8 ft (> than vapor head -33.2 ft gage) at approximately 1 second after pump trip. A review of the node Pump-1 and Pump-2 (pump outlet pipe at elevation 261 ft)) pressure plot in Fig. 1 and Table 4 reveals that the head at these nodes drop to pressure –6.3 ft (> than vapor head -33.2 ft gage) at approximately 2 seconds after pump trip. Therefore, surge mitigation devices are not necessary. 7.3 Case 2. Pump Speed Controlled Shutdown The Circulaing Water Pump Motors have non-reverse ratchets (preventing pump and motor reverse rotation). Speed deceleration was selected to calculate slightly smaller pressure at the pump and condenser outlets. Results of computer simulation show that minimum pressures occur at the condenser outlet and pump discharge before pump rotation speed shutdown (See Fig. 4 ???). 7.4 Case 3. Pump Startup Furing start, the CirculatingWater Pumps compress and vent the air in the pump discharge (between pump and butterfly valve) to the atmosphere through a 2 in pipe with an outlet orifice 1.25 in diameter. Butterfly valve opening time is 60 sec and starts openingaft3er the air in the discharges is vented.. Initial volume of compressed air is 30 ft3 (87 SCF). Maximum pressure at the butterfly valve is = 79 psi. The maximum design pressure for the pipes is 100 psi (See Table 6??? and Figs. 5 and 6???). In trial operation final orifice size should be selected 7.5 Maximum / Minimum Transient Pressure

The maximum transient pressure experienced by the CW system due to pump trip is not greater than the steady state pressure. The minimum transient pressure experienced by the CW system due to pump trip is about –8.8 ft gage (vapor pressure = -33.2 ft gage) at the condenser outlet.

8 RECOMMENDATIONS During trial operation of the pump start-up, the air outlet orifice should be selected to optimize pump startup time and pressure surges. Generally (i) small orifice: long starting time, low pressure surges, (ii) big orifice: short starting time, big pressure surges. Air outflow will be at sonic speed followed by high frequency noise and sound waterhammer at the end of air outflow. During start-up of the CW system air must be purged out of the system to avoid water hammer concerns. The Butterfly Valve starts opening when the pump has vented the air from the pump discharge line. Normal system start-up procedures (especially venting procedures) must be followed at all times. During start-up of the CW system after pump trip, air must be purged from the system to avoid water hammer concerns. It is recommended that normal system start-up procedures (especially venting procedures) be followed after a pump trip. The Butterfly Valve operators have maximum operating time of 60 second It is recommended that this naximum operating time be used.

9 TWO PUMPS TRIP AND SELECTION OF PUMP FILE FOR TRANSIENT ANALYSIS

Program Surge200 has 8 pump files. A pump file is a table of values defining head and torque as a function of flow and speed. These are based on available experimental data. The file selection is based on specific speeds. Transients for pumps are initialized by changing the pump speed ratio (pump speed/rated speed) or designating a pump trip where the rundown is calculated. The Circulating Water Pumps have a non-reverse ratchet. SURGE2000 simulate (i) pump trip: the pump speed following loss of power is calculated using dynamic analysis including torque, inertia, etc. If the butterfly valve at the pump outlet does not close, pump turns into the turbine operation with reverse flow and speed of rotation – runaway, (ii) Program simulates pump shutdown, pump start up, pump shutdown followed by startup (table or rated) changing the speed of rotation – input: speed versus time. SURGE2000 cannot graph or output table of pump speed of rotation and shaft torque, see Attachment EM1. The pump transient operating point and corresponding torque controls the pump rotatioanal speed, as it is programmed in the case of pump trip. Input data should be carefully selected to represent a real pump transient. Generally the flow reverse at a pump before the rotational speed reverse.

10 TWO PUMPS TRIP Results of calculations are shown in Figures 1 and 2,?? Table 4?? and Attachment TPT1. Attachment TPT1 shows envelopes of hydraulic grade lines. A review of the pressure envelopes reveals that vacuum occurs: - at the condenser located at the elevation 263.1 ft, nodes: J-17 and AV-H, - at the condenser located at the e,evation 254.8 ft., node AV-L, and - at the pump discharges, nodes Pump-1, and Pump-2. This case is simulated for 30 seconds to see the effect of 2 pumps operation followed by 2-pump trip. A review of the node AV-H (condenser outlet upper flange at elevation 263.1 ft) pressure plot in Fig. 1 and Table 4 reveals that the head at this node drops to pressure –8.8 ft (> than vapor head -33.2 ft gage) at approximately 1 second after pump trip. A review of the node Pump-1 and Pump-2 (pump outlet pipe at elevation 261 ft)) pressure plot in Fig. 1 and Table 4 reveals that the head at these nodes drop to pressure –6.3 ft (> than vapor head -33.2 ft gage) at approximately 2 seconds after pump trip. Therefore, surge mitigation devices are not necessary.

11 TWO PUMPS CONTROLLED SHUTDOWN

The Circulating Water Pumps have non-reverse ratchets. SURGE2000 cannot simulate pump trip and stop pump rotation at speed zero, see Attachment AM1. Input table: pump speed versus time was selected to follow pump trip pressure drop, estimating the time when pump speed should be zero, see Figure 4.

Speed deceleration is selected to calculate slightly smaller pressure at the pump and condenser outlets.

Estimated pump speed: Trip to zero speed

12 PUMP STARTUP 12.1 Air Release Orifice 0.9/1,25 in

The Circulating Water Pumps, when started, compress and vent the air between athe pump and the butterfly valve, to the atmosphere through the 2 in pipe with the outlet orifice 1.25 in. The butterfly valve opening time is 60 sec and starts opening when all air is vent d. The system is designed for pd = 100 psi = 231 ft of H2O pressure. Pump head at zero flow is H = 128 ft. Pressure surges should not exceed

2 ft 110)5.254261(128231 =−+−=∆+−=∆ zHpp d

The wave reflected at the closed butterfly valve will double the pressure amplitude. Maximum pressure in the orifice should not be more than ∆H= 55 ft. If the flow is stopped completely when the air is completely vented through the orifice (water velocity through the orifice is neglected to the sonic velocity of air outflow of 1120 ft/s) the basic equation of waterhammer describe a change in velocity as

This pressure force is oscillating with the high frequency and the mean value of 42000 lbf. The force is unbalanced since the pressure amplitude at the pump is very small and time delayed. Frequency of this quickly decaying force could be 30 Hz if there is no air in water. Residual air reduces the frequency and decreases the amplitude. SURGE2000 cannot calculate more accurately the pump startup and air outflow through the 1.25 orifice. The results are shown in Figure % and Table ? and ? Pump speed is 0 at 1 sec and full speed at 3 sec. Initial volume at the orifice is 30 ft3. This volume expands to the atmospheric pressure; than pump start, compress it to the zero flow pump head. This head is smaller (102.21 ft) then the real pump head 128 ft since program SURGE2000 use the internal four quadrant characteristics to calculate transients. Manufacturer did not supply the pump four quadrant data. The calculated pressures should be transferred for this difference 128 – 102 = 26 ft = 11.3 psi Maximum pressures at the butterfly vale of 67.7 + 11.3 = 79 psi is less than the maximum design pressure for the pipes of 100 psi. Pressure difference of pump zero flow head (128 ft) and SURGE2000 pump calculated head (102 ft) make difference in air density, further increasing air outflow and pressure surges. Table 5.

13 TWO PUMPS TRIP UNBALANCED AXIAL FORCES The SURGE2000 program is used to obtain heads and flow for unbalanced force calculations on straight pipes between two nodes (Number of nodes was increased to separate straight pipe segments, see Fig. ???). Elbow forces are not analyzed in this report 13.1 NOTATION TIME: Time (seconds) FORCE: Force (pounds) For each pipe in the network – Start node number 1 – head H1 (ft) – Flow Q1 (cfs) – Inlet area A1 (ft2) – End node number 2 – head H2 (ft) – Flow Q2 (cfs) – Exit area A2 (ft2) – Density of water ρ = 2205 lbm/ft3 (1000 kg/m3) – Acceleration due to gravity g = 32.17 ft/sec2 (9.81 m/s2) 13.2 Momentum Equation 13.2.1 If there are no obstructions in the fluid, and the effects of body forces are neglected,

the only force acting on the fluid in the straight pipe are (see Fig. 1): the pressure forces acting over the inlet and exit areas A1 , and A2, and the reaction force F exerted by the inner surface of the pipe on the fluid

• Σ(forces) = rate of change of momentum • f1- f2-F = ρQ2(Q2/A2) - ρQ1(Q1/A1) • F = f1- f2 - ρQ2(Q2/A2) + ρQ1(Q1/A1) • F = [f1 + ρQ1(Q1/A1) ] - [f2 + ρQ2(Q2/A2)] • F = [(H1

* A1 * ρg) + ρQ1(Q1/A1) ] - [(H2 * A2 * ρg) + ρQ2(Q2/A2) ]

SUGRE2000 calculates heads (H1 and H2), and flows (Q1 and Q2). Transient forces travels though the steel structure with the wave speed of about 16000 ft/sec (~5000 m/s); time delay and reflected forces are neglected in this analysis.

13.3 Preprocessor for TRANSIENT FORCES Overview of the results generated by the surge2000 program EXCEL format Create data in EXCEL format EXCEL FORCE Program Create results’ table, maximum value, and minimum value of the force and draw the chart. The resulting unbalanced force on straight pipe is presented in Table. ??? and Figs. ??? Maximum force is force acting from node 1 to node 2 if positive and minimum force is acting from node 2 to node 1 if negative (It is maximum force in opposite direction).
