2. Proposed situation

The area selected for the development of the wind farm, it is located in the periphery of Dolhesti commune (approx. at a distance of 1,4 km from the building fund of the Dolhestii Mari village) and in the periphery of Liteni city (approx. at a distance of 0,9 km from the building fund of the Corni village and approx. at 0,7 km from the building fund of the Rotunda village).

The area proposed for the wind farm is located on the peak of two hills (Hill Plesului and Hill Rotunda), benefiting from a good wind area and free of obstacles. For a better emplacement of the turbines and to properly mount them it was decided to split up the wind farm in two modules:

Module 1: emplaced on the Liteni city land, it will be comprised of 6 wind turbines with a 3 MW capacity ( surface studied in the PUZ 65 ha);

Module 2: emplaced on the Dolhesti commune, it will be comprised of 4 wind turbines with a 3 MW capacity ( surface studied in the PUZ 45 ha);

The zones that are studied in the two Zonal Urban Plans could allow additional turbines to be emplaced ( namely 7 more), in the case that the beneficiary will consider such a case.

The area selected for the emplacement of this wind farm presents several advantages, related to the high voltage transport lines, namely:

LEA 20kV ( to the South of the studied area, on the Dolhesti commune, but also to the North in the Liteni city);

LEA 110 kV ( to the West of the studied area, on the territory of Preutesti commune); LEA 220 kV ( to the North and North East of the studied area, on the territory of the Liteni

city);

Also in the close vicinity of the proposed wind farm, a EON substation is located in the Dolhasca

city (approx. 14 km). This close vicinity to the high voltage grid lines and the substation will facilitate

the grid connection of the proposed wind farm, reducing the costs generated by this.

3. Technical Information about the investment 3.1 Area and location

Module 1 periphery Liteni city

The topographic configuration of the land from the studied zone is cvasiplan, with height

differences between +384m and +428m.

GEOGRAFICALLYthe area in which the investment will be located is part of the morpho

corner period ....................................................................Tc = 0,7 sec;

the region falls in the rate 6 seismic region after Msk scale.

The studied zone presents several landslides, located on the East and South East of the Rotunda

Hill.

Also the land presents several characteristics improper for foundations, this creating the need for

additional works to stabilize the land. The current area is used at the moment for crops. Because of

this factor, during construction phase (for the turbine emplacements, for the technical spaces and for

the access roads) it will be necessary to remove the green cover, and replace it with a proper

mechanically stabilized layer.

Module 2 periphery Dolhesti commune

The topographic configuration of the land from the studied zone is cvasiplan, with height

differences between +459m and +496m.

GEOGRAFICALLY, the area in which the investment will be located, is part of the morpho

structural unit of Podisul Moldovei, subunit of the Podisul Sucevei, characterized by landscape

characterized by low hills and mostly covered by woods; The region is severed by the Somuzul Mare

valley ( generally oriented from West to East).

The form of the parcels in the field is an irregular one.

According to the norm P.100/1 2006, the area surrounding the Liteni city is characterized by

the fallowing values:

ground acceleration .............................................................ag = 0,16;

corner period ....................................................................Tc = 0,7 sec;

the region falls in the rate 6 seismic region after Msk scale.

The land studied does not have any particular geophysical characteristics, because of this there is

no need for special works regarding land improvement. At the moment the studied zone is used as

grazing land

This intersection between the county road DJ 208 and the communal road DC 6 will need to be

redesigned in order to accommodate the oversized transport vehicles.

The access road will need to undergo the fallowing intervention s in order to facilitate the access of

the oversized transport loads:

- Widening of the communal road DC 6 from the intersection with the county road DJ 208 for a length of 134 m;

- Reshaping, widening, ballasting and road paving with asphalt of the communal road DC

for

a

length

of

2533,15

m;

- Reshaping, widening, ballasting of the communal road DC 6 for a length of 134,72 m; - Reshaping, widening, ballasting and road paving with asphalt of the communal road DC

6 for a length of 1180,87 m; - Construction of stabilizing walls for a length of 2 X 195 m; - Construction of stabilizing walls for a length of 1140 m; - Works for stabilization of the Rotunda Hill for a length of 1140m;

- Reshaping, widening, ballasting of the service road DE 6A for a length of 2231,64 m; - Replacement of old culverts and mounting new ones where is the case (10 pcs.); - Arrangement of grooves and shoulders of the access roads for their entire length;

The construction of the access road will be made in order to have the fallowing road structure:

- Base layer of crushed stone of 30 cm thickness; - A layer of mixed ballast of 25 cm thickness; - Carriageway surface of 5 m; - Shoulders of 2 X 0,75 m; - Pears trenches 2 X 0,5 m; - Layer of Asphalt concrete ( rough) BAR 16 of 5 cm thickness ( in the places where the

technical solution imposes it);

Also on the area through which the access road leads to the module 1 of the wind farm, additional

stabilization works will be done for a length of 1180,7 m ( this works will be comprised of planting

shrubs that will help stabilize the Rotunda Hill).

Internal roads for the two models that make the current wind farm

The access in the t o mod les of the ind farm is pro ided as fallo s:

8/13/2019 FS final 10.2012

7/117


The roads layout will also be used to lay down the interconnection infrastructure for the two

modules (high voltage cables, data cables, etc.).

Works for stabilizing the Rotunda Hill

Taking in consideration the unstable character of the East and South East part of the Rotunda Hill,

several works for hill stabilization will have to be done, specifically in the area in which two of the six

turbines that make up the module 1 Liteni will be installed.

Works to arrange site organization

I order to properly arrange the site organization and in order to have a proper storage area for the

equipment that makes a turbine (the tower, nacelle, rotor, blades, etc.), a technical space was

considered. This technical space is located on Dolhesti commune land, has a surface of 22 ha, it is

located on the route of the access road and it is roughly in the middle of the two modules that

comprise the wind farm ( approx. 1 km from Module 1 Liteni and 2 km from Module 2 Dolhesti).

Construction works needed for emplacing and mounting of the wind turbines

For the two modules of the wind farm, the beneficiary took in consideration the same type of

turbines, namely wind turbines of 3 MW ( with a power factor between 0,9 and 0,95 imposed by

the solution study that was approved in the EON MOLDOVA CTE).

The specific characteristics of these turbines will be detailed in the specialized technical

memorandum ( that is annexed to the present study).

In conclusion, in the field, for each turbine, a foundation with a diameter of 22 m will be made

(permanent surface occupied by this is 380 sqm.). Also during the construction phase for the

foundations, the necessary cabling works (high voltage and data transmission) will be executed in

order to facilitate a proper work flow for the interconnection of the wind turbines. The effective

surface allocated to each turbine (specified in the tabulation papers) will be of 500 sqm. During the

construction phase a larger area will be available for the site organization for each turbine ( this is

specified in the public private partnerships done with the commune of Dolhesti and Liteni city and

also in the contracts made with private owners) to allow proper conditions for the mounting of the

turbine ( 3000 sqm. for each turbine).

The layout of the electric cables will fallow the route of the roads in order to avoid additional

8/13/2019 FS final 10.2012

The beneficiary, S.C ULLI ROWIND S.R.L, has a solution study that analyzes the possibility to connect a

wind farm with a capacity of 30 MW in the region of Liteni Dolhesti into the National Energy System

(SEN);

The analysis done by the specialty engineers, propose as a solution for insertion into the SEN

network the construction of a 110/MT substation in the location of the wind farm, and an

interconnection cable between this substation and EON 110 kV substation in Dolhasca ( high voltage

line, cable section 185 mm, length of approx. 14 km).

If

farm,

he

can

do so, having at his disposal an additional solution study that allows a total capacity of 80 MW in the

Dolhesti Liteni region, with insertion solution into SEN at same 110 kV EON substation in Dolhasca.

All categories of works described above, will be detailed in the Technical specialties memorandums that are annexed to the present study.

3.5 The current situation of utilities in the region

In the areas where the two modules of the wind farm will be emplaced, no networks for sewers,

water supply or gas are present.

The high voltage networks ( 20 kV, 110 kV and 220 kV lines) are situated at a safe distance from

the wind farm ( from both modules) and will not interfere with the construction procedures of the

wind farm.

The interconnection cable, the low voltage lines and one telecommunication line will have to be

taken in consideration during the engineering phase.

3.6 Environmental impact assessment conclusions

By making this park the beneficiary will take into account all the factors of pollution which could

have a negative impact on the two communities.

Protection areas for these types of systems have been studied in PUZ documentations performed

for the two modules Dolhesti and Liteni.

In both PUZ we can observe the location of the two modules of the wind farm has taken into

account the development priorities of the two communities (commune of Dolhesti and Liteni city)

1. General information

WinWinD has developed an innovative wind turbine for the market with itsWWD concept. WinWinDs basic values include customer satisfaction and

the operational reliability of the products, as well as the win-win cooperationachieved between the clients and WinWinD.

On the basis of thorough technical and economic research work the WWDconcept, which allows electricity to be produced with a new innovative inte-grated power unit, was created. The basis for design was efficiency, reliabil-ity and ease of maintenance which allows the WWD concept to offer themost cost-effective production throughout its total life, combined with thelowest operating costs.WWD-3 is pitch regulated upwind wind turbine with active yaw and three-blade rotor. The turbine consist of three main parts

Rotor3 blades and hub, electrical pitch control

Integrated power unitroller bearing, planetary gear and variable speedgenerator with permanent magnets

Nacellefrequency converter, transformer and accessories

The rotor hub is connected to the gearbox casing using a play-free double-row tapered roller bearing. The bearing transfers the rotor loads directly tothe main casing, keeping the drive train free from deformation and rotorloads. The planetary gear increases the rotating speed modestly and trans-fers the torque to the low speed permanent magnet generator. All connec-tion flanges are round and concentric resulting in clearly defined borders

The frequency converter is also water cooled and installed in the nacelle.The frequency converter consists of two separate converter units. One con-verter unit is designed for 1,5MW and has 1500A IGBT-inverter units ongrid and generator side. This 2x1,5MW converter system is redundant, it ispossible to run only one 1,5MW converter if another converter is out of or-der. On the grid side there is an LC-filter for reducing harmonic currents.

The main transformer is also installed in the nacelle. It is an oil-cooled fullyencapsuled version, reinforced internally to withstand vibration. Additionallyit stands on vibration dampers. Consequently all the cable connections aremade flexible. Cooling is by natural convection plus a thermostat-controlledadditional fan. The main transformer has five voltage tap settings (2x2,5%)to make a fine adjustment according to the local grid.

6.2. RotorThe rotor consists of three blades, hub and three electrical pitchdrives. The blades are made of epoxy resin reinforced glassfibre.The blades also act as aerodynamic brakes. Normally the bladesare synchronised but in case of an emergency, each blade can becontrolled individually. The pitch system is electric and equippedwith a back-up battery or capacitor. The blades are equipped withlightning conductors.

6.3. Main bearing, planetary gear and generator.The rotor hub is connected to the gearbox casing using a play-free double-row tapered roller bearing. The bearing transfers the rotor through a part ofthe gear casing to the mainframe. The planetary gear increases the rotatingspeed modestly and transfers the torque to the low speed permanent mag-net generator. All connection flanges are round and concentric, resulting inclearly defined borders. This "black-box" design philosophy eases assem-bly and results in a well-defined load distribution. All possible deformationsdue to rotor loads have been taken into consideration when designing thegears.

The bearing has, integrated with the gearbox, forced oil lubrication. A dou-ble radial shaft seal arrangement with grease filling in between seals to-

6.4. Brake system

During emergency shutdown each rotor blade acts independently as anaerodynamic brake. The computer controls the system with the help ofanemometers, wind vane and other sensors.

The stop procedures are:

The normal stop : the blades synchronously driven into stormproofing position with a pitch speed of 4 degrees/s without us-ing the mechanical brakes.

The emergency stop (low-level) : the blades are driven with 4deg/s to the end position and the mechanical disk brake is acti-vated at the same time. In case of grid failure the pitch powercomes automatically from the buffer battery

The emergency stop (high-level) : the blades are driven witha certain pitch speed program. The mechanical brakes areused at the same time. In case of grid failure the pitch powercomes automatically from the buffer battery.

Each blade is equipped with a back-up battery. If one of the blade pitchesfails, the synchronisation is turned off and each blade is driven separatelyto the storm position. In case of grid failure using the battery power shall beused.

The system meets the standards of Germanischer Lloyd.

6.5. Glassfiber cover

Nacelle and hub cover are made of glassfiber sandwich. The colour is RAL7035 grey.

6.7. Foundation

The foundation is a gravity-based or pile foundation depending on the localground conditions.

The tower is connected to the foundation by a cylindrical bolted flange.

6.8. Grid connection

The main transformer in the nacelle is manufactured to meet the nominalvoltage of the interconnection grid. The transformer has adjustable windingtaps 2x2,5% and the voltage of the high voltage grid must be within 5%of nominal voltage. Frequency variations within 3 Hz (50 Hz) can be han-dled. Intermittent or rapid grid frequency fluctuations may cause damage tothe turbine. For the fatigue loads, 400 grid failures within the turbines life-

time have been assumed.

6.8.3 Frequency converter

A liquid cooled IGBT frequency converter is used for connecting the vari-able speed generator to the grid. The frequency converter consists of twoparallel connected converters (2x1,5MW) in separate cabinets resulting arobust and redundant system. The voltage level of converter grid side is690V and the grid synchronization is automatic. The power factor of gen-erator and grid side converters is adjustable. The communication betweenoperation control computer and the converter is made by CANopen field-bus. Due the effective grid side filters, the total harmonic distorsion of thegrid side current is low (THD < 4%).

6.8.4 Reactive power control

The reactive power of WWD-3 turbine can be adjusted by the frequencyconverter. It is possible to control the grid side reactive power by followingwaysPower factor = 1,0 (default)Power factor < 1,0 according to max reactive power diagram. (Note that thediagram shows the maximum value and lower reactive power productioncan be agreed).

The turbine is able to operate with a power factor of cos=0,95 (ind) tocos=0,95 (cap) with the nominal power. With partial loads the maximum

reactive power diagram is shown in figure X. Note that if a power factor

Data connection to the park can be made using broadband access, an

ISDN connection, an analogue telephone line or a GSM connection. Themost recommended method is broadband.

The production data is automatically retrieved from the wind turbine PLC tothe WinWinD Web-server. From the Web-server data can be made avail-able to customers.

The turbine control software contains several state-of-art features, which al-lows optimisation of the production based on needs of the customer, for ex-ample production optimised or noise optimised power curves, etc.

Wind turbines can be fully remote controlled, i.e. all the main functions canbe executed remotely.

6.10. Presenting the production data on the Internet

The system enables presenting the production data of the wind turbines onthe Internet. Access to the data can be free or a username with passwordcan be used. Thus the production data can be viewed regardless of theplace or time; the Internet-connection, however, is a necessity.


8/13/2019 FS final 10.2012

31/117


6.12. Self-diagnosis of the wind turbine

The wind turbine is equipped with an automatic monitoring system, whichcontinuously protects and controls the generator and the grid and adjuststhe settings according to the wind and weather conditions. This way thepower production can be optimised. During the cold season the sensorsmeasure the need for heating of the power unit and lubrication oil and en-sure a safe start.

For case of a grid drop the wind turbine has an uninterruptible power sys-tem (UPS), which ensures the control for 60 minutes.

The anemometer and wind vane of the wind turbine monitor the changes inthe wind and the technique starts and stops the plant according to the set-tings.

6.13. Condition monitoring

The mechanical reliability of the wind turbine is ensured with a conditionmonitoring system. E.g. vibration and temperature is measured by usingsensors. Condition monitoring system analyses the data received from thesensors and gives a warning to the turbine controller if alarm limits are ex-ceeded. Condition monitoring system provides trends, frequency spec-trums, time domain signals as well as technical details of the wind turbine toenable accurate analysis of possible faults.

6.14. Lightning protection

The most advanced lightning protection technology in the field is used. Thefollowing principles are applied

Lightning conductor in each blade Optional registration cards Varistors and fuses in the terminal box of the generator Varistors and fuses on the connectors of the inverter Shielded sensor cables Overvoltage protection on the high voltage side of the transformer

7. Earthing system

The earthing system of WWD-3 turbine consists of a ring type earthingelectrode around the foundation in the soil and connection wires from thering to the flange of the tubular tower. The main earthing bus-bar is alsoconnected to the flange of the tower and the earth termination shall have aresistance 10 . The 50mm2 copper electrode is used as a electrode wireand the electrode joints in the soil shall be weld joined to get permanentand low-resistance connections. The earthing system must be designed for

local soil conditions and if the resistance of 10 cant be met with ring typeelectrode, then ground rods must be added to the earthing system.The star point of the main transformer is earthed, which means that the tur-bine main circuit is a TN-system.

8. Options

8.1. Anti-icing of blades

Ice sensors or an anti-icing equipment of the blades is available as an op-tion.

8.2. Aviation lights

The following aviation light options are available:

1. Low intensity. Red 10-200 cd.2. Medium intensity. Red/white/dual 200-2000 cd.3. Medium intensity. Red/white/dual 2000-20000 cd.

The options are designed according to the ICAO and the FAA codes.

When installed in a wind farm, the obstruction light flashes can be synchro-nised throughout the whole wind farm.

8.4. High voltage switchgear

The high voltage switchgear can be delivered as well.

9. Type Approvals

The Design Assessment is the equivalent to the German Typenprfung. Itis a certification of the basic documents of the machine, stating that thesafety philosophy is correct, all safety devices and machine componentsare correctly dimensioned and the machine has the calculated lifetime of 20years.

The WWD3 is being assessed by Germanischer Lloyd (GL). The designassessment is valid for the machine head (Rotor and Nacelle).

The tower will be certified separately, because it is often designed site-specific. Winwind performs the tower certifications through TV Tech-nischer berwachungs Verein.

All data are valid at sea level (1,225 kg/m3). Periodic operational disturbances and generator power de-rating

may be caused by a combination of high winds, low voltage or hightemperature.

WinWinD recommends that the electrical grid is as close to nominalas possible with little variation in frequency.

A certain time allowance for turbine warm-up must be expected fol-lowing a grid dropout and/or periods of very low ambient tempera-ture.

All listed start/stop parameters (e. g. wind speeds and temperatures)are equipped with hysteresis control. This can, in certain borderlinesituations, result in turbine stops even though the ambient conditionsare within the listed operation parameters.

General technical report

1. General Considerations

The beneficiary, SC Ulli ROWIND SRL, together with the general designer set the location of a total of 10 wind turbines, each with a capacity of 3 MW, in the localities Liteni and Dolhesti.

Following wind measurements made to determine the optimal location the hills Rotunda and

Plesului were chosen.

After studying ways of access, ownership papers identified in the field a conclusion has been reached to establish two wind farm modules that will form Liteni Dolhesti investment, as follows:

Module 1 Liteni, will contain a total of 6 wind turbines with an installed capacity of 3MW/turbine (PUZ studied area 65 ha);

Module 2 Dolhesti, will contain a total of 4 wind turbines with a capacity of 3 MW/turbine (PUZ studied area 45 ha);

Corroborating with the situation in the field with the one in the solution study, the data provided by the manufacturer of turbines has led to the following scheme selection area:

Module 1 periphery Liteni city

The land studied is in the public domain of the Liteni city but also some emplacements belong to private owners:

4 of the wind turbines will be located on land owned by the Liteni city (4 X 500 m permanently occupied , 4 X 2500 m occupied during construction phase);

2 of wind turbines will be located on private land owners (2 X 500 m permanently occupied , 2 X 2500 m occupied during construction phase);

Technical space will be located on land owned by the city of Liteni (1 x 3000 m); The wind farm access road (to be achieved by upgrading and rehabilitation of communal

road DC 6 over a length of 1180.87 m and a width of 5 m carriageway and shoulders of 2 X 0.75 m);

Internal roads of the wind farm will be made on land belonging to the city of Liteni on an

0.75 m, and the rehabilitation 6A service road over a length of 2231.64 meters, with a roadway width of 5 m and shoulders of 2 X 0.75 m);

Internal roads of the wind farm will be made on land belonging to the commune of Dolhesti on an area of 7414 square meters.

2. Technical Considerations

Given the fact that the investment Building wind farms in LiteniDolhesti region takes place within the territory of two administrative units, technical documentation will treat each

UAT separately, namely Module 1 to UAT LIteni city and Module 2 on UAT Dolhesti commune.

To ensure investment in the area will be made the fallowing mandatory cadastral works:

Verification of the tabulation / Properties papers available; It will bring up to date all land documents in accordance with the laws in force; It will get excerpts land for each parcel will be subject to investment; It

will

Access road report

1. General Considerations

As with all the parts from the current investment, namely Construction of a wind farm in the

Dolhesti Liteni region, also the access road has to be divided up and treated into 2 separates

documentations, based on the fact that the two modules of the wind farm are located on two

separate administrative entities: Liteni city and Dolhesti commune.

2. Description of the investment

The main access road to the wind farm will be constituted by the communal road DC 6. This road

it connects to the county road DJ 208, that will serve as main road for accessing the region Liteni

Dolhesti.

In order to accommodate the overload transport capacity (caused by the supply transport with

turbine equipment), the intersection between DC 6 and DJ 208 needs to be redone, by widening the

intersection in order to meet the minimum curve requirement for the oversized transport.

Module 1 Liteni:

The access road to the Liteni module is made up by the communal road DC 6.

Module 2

Dolhesti:

The access road to the Dolhesti module its comprised from two roads:

Communal road DC 6; Service road DE 6A;

3. Technical Data

Module 1 Liteni

To achieve access to the wind farm module in the Liteni city , Suceava County, the following

interventions are required:

The road is not paved and specific road shows and strains degradation of land, weak gravel and

unmaintained;

On the road platform existence of settlements was showed, forming potholes and ruts;

No road system clearly revealed, previously performed ballasting works being made especially in

critical places routes with plastic roadbed due to water stagnation, but not solved the problem of

water leakage from the road continues Platform degradation;

Existing ditches for storm water discharges are down and no longitudinal slope and stagnant water

in closed basins, where the slope is greater lateral longitudinal grooves, after rainfalls fallen,

accumulate water flow at high speed produces degradation of the road platform, these sections must

be performed pears concrete ditches;

Existing culverts are damaged (broken or completely tubes are clogged);

Existing culverts are appropriate section tube to drain existing gullies or water flow in ditches;

No different from the carriageway verges, no cross slope to drains, stagnant water in ponds platform accelerates the degradation process;

The road is not stabilized; the land on which is laid out has a serious landslide problem, because of

this a supporting wall is needed;

Geometry of the cross and longitudinal slopes cannot ensure correct operation of culverts;

Missing work for traffic safety;

Indicators for kilometers and indicators for hectometer are missing; no traffic indicators that have

fluency traffic on these roads, connecting the county road DJ 208 and the communal road DC 6 are

not arranged there. Danger of accidents in these intersections area being made.

Key features of the proposed constructions

Total length of roads: 1180.87 m of which:

Communal roads: 1180.87 m;

Carriageway area: 5904.35 sqm of which:

Module 2 Dolhesti

To achieve access to the wind farm module in the Dolhesti commune , Suceava County, the following

interventions are required:

widening of the intersection between the communal road Dc 6 and the county road DJ 208;

widening of the communal road DC 6 from the intersection with DJ 208 for a length of 134 m;

Reshaping, widening, ballasting , paving the way with asphalt of the communal road DC 6 over a

length of 2533.15 m;

Reshaping, widening, ballasting of the communal road DC 6 over a length of 134,72 m;

Reshaping, widening, ballasting of the service road DE 6A over a length of 2231.64 m;

The land on which the proposed work is situated is owned by Dolhesti commune.

Existing situation:

In terms of technical condition, communal road under study is as follows:

Does not have adequate bearing capacity for taking a traffic needed construction and operation of

wind farms;

The road is not paved and specific road shows and strains degradation of land, weak gravel and

unmaintained;

On the road platform existence of settlements was showed, forming potholes and ruts;

No road system clearly revealed, previously performed ballasting works being made especially in

critical places routes with plastic roadbed due to water stagnation, but not solved the problem of
