Ehitusprojekti koostamise alusdokumendiks on kehtestatud Uuevärava, Tiigi ja Sarapuupõllu detailplaneering, DP Projektbüroo OÜ töö nr 01-18-DP. Projekti realiseerimise eesmärgiks on Uuevärava kinnistule Vestas V47 elektrituuliku võimsusega 500 kW, torni kõrgusega kuni 65 m ja rootori diameetriga kuni 47 m rajamine. Elektrituuliku konstruktsiooni ja vundamendi arvutused ning joonised on väljastatud firma Vestas poolt (lisa, elektrituuliku Vestas V47 tehniline spetsifikatsioon) Projekti väljaehitamisel lähtuda kehtivatest normdokumentidest: Ehitusseadustik (RT I, 05.03.2015, 1); Elektriohutusseadus (RT I 2007, 12, 64), Nõuded ehitusprojektile, (Majandus- ja taristuministri määrus nr 97, vastu võetud 17.07.2015). Enne ehitustööde algust tuleb ehitajal kirjalikult teavitada tööst puudutatud kinnistu(te) omanikke töödega alustamises, tähitud kirjaga või allkirja vastu vähemalt 3 päeva enne töödega alustamist. Tööde alustamisel tuleb informeerida tehnovõrkude valdajaid ja vajadusel täpsustada tehnovõrkude täpne asukoht surfimise teel ja kutsuda kohale trassi valdaja esindaja. Ehituse käigus kahjustada saanud maa-alune kommunikatsioon tuleb ehitajal nõuetekohaselt taastada. Ehitustöödel tekkinud küsimused ja probleemid lahendada töö käigus kooskõlastatult projekteerija ja tellijaga. Tööde alustamine on võimalik peale ehitusloa saamist omavalitsuse territooriumil kehtestatud alustel ja korras. Ehitustöödele eelnevad ehitiste ja rajatiste mahamärkimistööd on kohustuslikud. Peale käesoleva projektiga kavandatud ehitiste ja rajatiste valmimist tuleb kohustuslikus korras koostada teostusjoonised. Mõõdistus tuleb teostada mahus, mis võimaldab ehitusjärgselt kindlaks teha kasutusse antud rajatiste asukohta looduses (ka kõrguslikult). Vestas V47 elektrituuliku projekt, Uuevärava kinnistu, Sikassaare küla, Saaremaa vald DP Projektbüroo OÜ Elektrituuliku eelprojekt, töö nr. 15-23-EP Projekti koostamise kuupäev 24.03.2023 1.2 Asendiplaaniline osa Elektrituuliku asukoht Uuevärava kinnistu asub hajaasustusalal, katastriüksuse registreeritud sihtotstarve on 100% maatulundusmaa, kasutuses haritava põllumaana. Detailplaneeringuga määratud sihtotstarve on 95 % maatulundusmaa ja 5% tootmismaa. Elektrituuliku asukoht on projekteeritud Uuevärava kinnistu põhjapoolsesse ossa kuivenduskraavi lähedale. Poldrialale varem rajatud elektrituulikud jäävad 280 m (Tiigi kinnistul) ja 267 m (Sarapuupõllu kinnistul) kaugusele. Uuevärava katastriüksus piirneb põhjast Põlluääre ja Laasimetsa katastriüksustega, lõunast Sarapuupõllu ja Käenometsa katastriüksustega, idast Vene ja Käenometsa katastriüksustega ning läänest Tiigi ja Luguse katastriüksustega. Projekteeritav elektrituulik asub maaparandus- süsteemi maa-alal Sikassaare polder. Tuulik ühendatakse Sarapuupõllu kinnistul asuva alajaamaga, kus asub ka liituumispunkt. Juurdepääs Uuevärava kinnistule toimub 21140 Kuressaare-Sikassaare teelt ja Sikassaare-Upa teelt läbi Tiigi kinnistu eratee. Elektrituuliku kõrgusega ekvivalentne ringjoon (mõjuala) ulatub Tiigi, Põlluääre ja Laasimetsa kinnistutele. Elektrituuliku masti ja tiiviku põhjustatud varjutus naabekinnistute õuealasid ega puhkealasid ei koorma. Lähim elamu (Metsa, kat.tunnus 27003:001:1008) jääb projekteeritavast tuulikust ca 620 m kaugusele lääne poole, Liiva (kat.tunnus 27003:001:0866) kinnistu tootmishoone jääb projekteeritavast tuulikust ca 570 m kaugusele lääne poole. Väljavõte Maa-ameti X-Gis kaardirakendusest projekteeritava tuuliku asukohaga (24.03.2023) Elektrituulik Elektrituulikuks on tellija valinud Vestas V47 võimsusega 500 kW. Elektrituulik koosneb gravitatsioonitüüpi raudbetoon madalvundamendist, koonilistest tornisektsioonidest, gondlist ja rootorist koos tiivikuga. Torni kõrgus maapinnast on kuni 65 m ja absoluutkõrgus 66,6 m. Tuuliku rootori diameter on kuni 47 m. Elektrituuliku maksimaalne kõrgus vundamendist tiiviku tipuni on 81 m, absoluutne kõrgus 82,6 m. Ehitisesalune pind on 145,0 m2 Vestas V47 elektrituuliku projekt, Uuevärava kinnistu, Sikassaare küla, Saaremaa vald DP Projektbüroo OÜ Elektrituuliku eelprojekt, töö nr. 15-23-EP Projekti koostamise kuupäev 24.03.2023 (vundamendi alune pind). Tuuliku torn monteeritakse raudbetoonist ümmargusele seentüüpi või kaheksakant betoonvundamendile läbimõõduga 12,5 m. Elektrituulik ja vundament rajatakse vastavalt Vestas V47 tehnilisele spetsifikatsioonile. Tuuliku gondlile tuleb paigaldada kaks lennuohutustuld, mille parameetrid peavad vastama Rahvusvahelise Tsiviillennunduse Konventsiooni lisa 14 (ICAO Annex 14) tabelis 6-1 kirjeldatud madalintensiivsusega tüüp B tulede nõuetele. Vastavalt Sotsiaalministri määrusele „Müra normtasemed elu- ja puhkealal, elamutes ning ühiskasutusega hoonetes ja mürataseme mõõtmise meetodid“ on müra normtasemed eluhoonetes päevasel ajal 40 dB ja öisel ajal 45 dB. Projekteeritava elektrtuuliku müra normtasemed jäävad määruses nõutud mürataseme piiresse, kuna eluhooned asuvad elektrituulikust piisaval kaugusel. Tuulikute tekitatav müra sõltub tuule tugevusest. Vaiksema tuule korral on tuuliku pöörete arv väiksem ja sellega koos müratase madalam. Tuule kiiruse kasvamisel pöörete arv suureneb, kuid samal ajal tugevneb ka looduslik mürafoon, mis teataval määral varjestab tuulikute müra. Müraraport on esitatud elektrituuliku Vestas V47 tehnilises spetsifikatsioonis. Teed ja platsid Juurdepääs Uuevärava kinnistule on tagatud 21140 Kuressaare-Sikassaare teelt läbi eravaldustes kulgeva Sikassaare-Upa tee, mis läbib Marguse, Haagi, Metalliääre, Liivaääre, Soomi, Kuressaare metskond 90 ja Tiigi kinnistuid. Elektrituuliku püstitamiseks ja teenindamiseks on projekteeritud olemasolevalt teelt kruuskattega juurdepääsutee ning teenindusplats vastavalt nõuetele, mis tagavad raske- ja päästetehnika liiklemise. Projekteeritav elektrituulik, selle teeenindamiseks vajalik juurdepääsutee, plats ja liitumiskaabel asuvad maaparandussüsteemi maa-alal Sikassaare polder (tunnus 7116450020080001). Ehitustööde teostamisel maaparandussüsteemi maa-alal arvestada asendiplaanile orienteeruvalt kantud maaparandusrajatistega. Enne ehitustöid tuleb lahti- kaevamise teel teha kindlaks torude täpne asukoht ja sügavus. Drenaaži vahetus läheduses teostada kaevetööd käsitsi. Kuna maaparanduse teostusjoonised on informatiivsed ja drenaaži asukoht on orienteeruv, siis saab looduses orienteeruda suudmete ja kaevude asukohtade järgi. Juurdepääsutee ja teenindusplats tuleb võimalusel rajada ülalpool drenaažisüsteemi. Juhul, kui rahjamissügavus on suurem, tuleb tee ja teenindusplatsi alla jäävad savitorud asendada sama siseläbimõõduga plastoruga (rõngasjäikus SN 8), et vältida hilisemaid drenaažiprobleeme (nt läbivajumine, purunemine). Savitorude ühendamised plasttorudega teostada vastavaid muhve kasutades. Juurdepääsutee rajamise korral drenaažitorudele lähemale kui 2 m tuleb savitorud asendada plasttorudega (rõngasjäikus SN 8) ja teostada nõuetekohased ühendused. Kollektori lõhkumine on keelatud, sest selle tagajärjel halvendatakse kõrval asuvate katastriüksuste kuivendussüsteemi toimimist, st tekib liigniiskus. Juurdepääsutee asukoha valikul tuleb juhinduda sellest, et tee ületaks drenaaži minimaalselt, st valida koht, kus tee läheb üle vähima arvu torude ja ei ületaks drenaaži ühenduskohti. Ehitustööde käigus vigastatud drenaaž tuleb nõuetekohaselt taastada ja maaparandussüsteem peab peale ehitustöid jääma nõuetekohaselt toimima. 1.3 Ehituskonstruktsioonide ja tehnoloogia osa Vundamendi projekti aluseks on VESTAS V47 tuuliku vundamendi tehase poolt koostatud originaaljoonised. Vundament valatakse r/b taldmikule ja kindlustatakse täitematerjaliga. Kõik elektrituuliku mastist ülekanduvad jõud peavad saama vastu võetud vundamendiga. Seda saavutatakse reguleeritavate ankrupoltide ringiga vundamendi peal. Joonised ankrupoltide kohta annab iga torni puhul eraldi Vestas. Torni ja rootori kogumass esitatakse Vestas V47 elektrituuliku projekt, Uuevärava kinnistu, Sikassaare küla, Saaremaa vald DP Projektbüroo OÜ Elektrituuliku eelprojekt, töö nr. 15-23-EP Projekti koostamise kuupäev 24.03.2023 vastavalt tehase toodangu andmetele. Elektrituuliku vundamendi mass peab ületama torni ja rootori kogumassi vähemalt kolmekordselt. Kõik elektrituuliku mastist kulgevad kaablid läbivad vundamenti ning seetõttu peab läbiviik olema peidetud ja sisestatud kaitsetorudesse. Vundamendi läbimõõduks on 12,5 m ning rajatakse maapinnaga ühele tasapinnale. Vundamendi sisse on valatud VESTAS V47 terastorni alumine sektsioon, mille külge kinnituvad torni ülejäänud sektsioonid. Tuuliku vundament on valatud monoliitsest raudbetoonist C30/37 arvestades kõiki tuulikuid tarniva firma tehnilises ülesandes toodud nõudeid. Betooni kvaliteet peab vastavama EN206-1 nõuetele. Kõik betoonkonstruktsioonid peavad vastama järgmiste normdokumentide nõuetele: Eurocode 2 : EN 1992-1:2004 Design of Concrete Structures Eurocode 7: EN 1997: Geotechnical design Armeerimine teostatakse vastavalt armeerimisjoonisele. Elektrituuliku torni ja tiiviku püstitamiseks kasutatakse elektrituuliku Vestas V47 tehnilist spetsifikatsiooni. Esimeses etapis monteeritakse vundamendile koonilised tornisektsioonid, seejärel kinnitatakse kondel ja lisatakse tiivik. 1.4 Elektri- ja sidepaigaldiste osa Elektripaigaldised Elektrituuliku liitumine võrguga on projekteeritud madalpingel läbi olemasoleva liitumispunkti, mis asub Sarapuu kinnistu alajaamas projkteeritavast elektrituulikst ca 220 m kaugusel. Rajatavate elektripaigaldiste kohta koostatakse eraldi tehniline projekt. Maandused. Vastavalt elektrituuliku tehnilistele nõuetele tuleb projekteerida ja välja ehitada maanduspaigaldis, milline peab tagama maandustakistuse maksimaalselt kuni 10Ω. Vaskmaandur 50 mm² paigaldatakse ümber tuuliku torni ning maandatakse vajadusel kahest vastastikusest punktist vertikaalsete 6 m elektroodmaanduritega. Maanduse rajamiseks koostatakse eraldi tehniline projekt. Side. Elektrituulik ühendatakse kiudoptiliste kaablite kaudu andmesidevõrku. Kiudoptilised kaablid paigaldatakse samadel trassidel samadesse kaevikutesse tuulikut teenindavate kaablitega. Paigaldatavate sidekaablite ühenduste kohta koostatakse eraldi projekt elektriprojekti koosseisus.

Introduction The Vestas 660 kW wind turbines are based on the experience gained from the V39-500 kW and V39/42/44-600 kW wind turbines. The Vestas 660 kW wind turbines are available in two versions with the same swept areas and the same climatic conditions. The difference between the two versions consists in the V47-660 kW having a synchronous rotor speed of 28.5 rpm and one generator. The V47-660/200 kW has two seperate generators running at two different synchronous speeds (26 and 20 rpm). The V47 turbines uses the superior variable slip concept, which was introduced in the Vestas 600 kW turbines (V39/42/44). This feature ensures a smooth power output and at the same time reduces the loads significantly. The special Vestas Optitip® feature is standard on both Vestas 660 kW turbines. This feature provides the optimum tip angle at all times with respect to power performance and noise emission. 2. Type Approvals The wind turbines are designed in accordance with IEC 1400-1 , DS472 (“Teknisk Grundlag”), Germanisher Lloyd IV part 1 and NEN 6096/2. 3. Climatic Conditions The wind climate for a given site is normally specified by a Weibull distribution. The Weibull distribution is described by an A and a C factor. The A factor is proportional to the mean wind speed and the C factor defines the shape of the Weibull distribution or in other words long term variations of hours at different wind speeds. Turbulence is the factor which describes short term wind variation/fluctuations. In the table below the design wind conditions for the Vestas 660 kW wind turbine are listed.

Country specific conditions and approvals. Concerning park installations the conditions of section 9 are to be observed, and for other conditions Vestas must be consulted. 3.1 Stop wind speed / restart wind speed The turbine stops for high wind speed when the exponential mean wind speed averaged during 100 seconds is above the stop wind speed level. The turbine restarts when the exponential mean wind speed averaged during 100 seconds, is below the reset wind speed, and stays below the stop wind speed for 1 minute. 3.2 Site specific loads The turbines can be placed under various climatic conditions: where the air density, turbulence intensity and the mean wind speed are the parameters to be considered. If the turbulence intensity is high the turbine loading increases and the turbine lifetime decreases, on the contrary the loading will be reduced and the lifetime extended if the mean wind speed or/and turbulence is low. Therefore, the turbines can be placed on sites with high turbulence intensity if the mean wind speed is suitable low. Vestas has to examine the climatic conditions if the prescribed is exceeded. 3.3 Low Temperature version The VestasV47-660 kW turbine is also available as a Low Temperature version. __________________________________________________________________________________ Vestas 660 kW Variable Slip Wind Turbine, V47-660 kW and V47-660/200 kW Date: 02-05-00 Class: 1 Item no.: 943111.R4 Page: 5 of 27 This version is equipped with special heat treated steel components when necessary, and the nacelle has built in heaters.

Variable slip, Optislip So far the normal way of operating asynchronous wind turbine generators has been that of constant speed. An induction generator operates with almost constant speed normally within 100% to 101% of nominal speed. For a four pole generator this means operation from 1500 rpm (no load) to 1515 rpm (full load) at 50 Hz frequency. This small variation is considered insignificant, and this is why operation mode is called constant speed. When the wind speed changes it will result in corresponding power output changes. When nominal power is reached power fluctuations are undesirable. Vestas introduced pitch regulation because this feature enables maximum power to be limited to nominal as an average at high wind speeds. However, with a fixed speed generator, power fluctuations are so fast that it is only possible to keep the average power constant, and therefore rapid fluctuations will occur. These rapid fluctuations contribute to the loading of the turbine. In order to minimise the loads Vestas introduced the variable slip concept together with the V39/42/44-600 kW wind turbine and reused this concept for the Vestas V47 turbine. This feature means that it is possible electronically to vary the slip within 10% (1500 - 1650 rpm). The variable slip feature is used when a wind gust hits the rotor. The controller then allows the speed of the generator to increase slightly in response to the gust. At the same time the pitch system turns the blades to a less aggressive angle and thereby decreases the rotor rpm. The result is a 100% constant and smooth power output with a minimum of loads on; blades, main shaft and gearbox. The variable slip is a very simple, reliable and cost effective way of achieving load reductions compared to more complex solutions such as full variable speed using full scale converters. __________________________________________________________________________________ Vestas 660 kW Variable Slip Wind Turbine, V47-660 kW and V47-660/200 kW Date: 02-05-00 Class: 1 Item no.: 943111.R4 Page: 13 of 27 7.

Installation Terrain: If the terrain within a 100 m radius of the turbine has a slope of more than 10o, certain considerations may be necessary. Climatic conditions: The turbine is designed for an ambient temperature range from -20°C up to + 40°C, (10 min. average). The temperature range for the LT-version is –30°C up to + 40°C (10 minutes average). Outside these temperatures the turbine will stop and certain considerations may be necessary. The turbine can be placed in wind farms with a distance of min. 5 rotor diameters (235 m) between turbines. If the turbines are placed in only one row (perpendicular to the predominant wind direction) the distance between the turbines must as a min. be 4 rotor diameters (188 m). For operation under different conditions contact Vestas. The humidity can be 100%, (max. 10% of the time). Corrosion protection according to corrosion class 3 outside, and 1 to 2 inside, (DS/R 454). Grid connection: Intermittent or rapid power fluctuations of utility grid frequencies may cause serious damage to the wind turbine. Steady variations within + 1/-3 Hz are acceptable. The voltage operational range shall be within + 10/-6 of nominal. Grid drop-outs should only take place once per week as an average over the lifetime of the turbine. A ground connection of max. 10 Ω must be present. Furthermore, it is recommended that the turbine is connected to a TN-grid. In case of small independent grids, it will be necessary to check the actual conditions. The 5th and 7th. harmonics are sinusoidal voltage with frequencies at 250Hz and 350Hz respectively. Harmonics are caused by different equipment (e.g. welding machines), which via a transformer is connected to same power supply systems as the wind turbine. Harmonics in the power supply systems reduce the lifetime of the capacitor. The impedance voltage of the transformer and the size of the power factor correction are very important for the acceptable level of harmonics. • If a 800kVA transformer with 4.5% impedance voltage is used together with the 250 kVAr power factor correction, the 5th and 7th harmonics have to be below 3% and 2% respectively. • If a 800kVA transformer with 6% impedance voltage is used together with the 250 kVAr power factor correction, the 5th and 7th harmonics have to be below 3% and 1% respectively. It is recommended to use a 800kVA transformer with 4.5% impedance voltage for a V47-660kW wind turbine. 10. General reservations Derating of nominal power may occur with a combination of e.g. high wind, low voltage or frequency and high temperature. __________________________________________________________________________________ Vestas 660 kW Variable Slip Wind Turbine, V47-660 kW and V47-660/200 kW Date: 02-05-00 Class: 1 Item no.: 943111.R4 Page: 18 of 27 In general it is recommended that the grid voltage is as close to nominal as possible. A stationary frequency below nominal will influence the power curve. In connection with a grid drop-out and very low temperatures, a certain time of heating-up must be expected before the turbine restarts after re-establishing of the grid. If the wind turbine is placed in more than 1000 m above sea level, a higher temperature rise than usual might occur in generator, transformer and other electrical components. In this case a periodic reduction of rated power might occur, even if the ambient temperature is within the specified limits. Furthermore, also at sites in more than 1000 m above sea level there will be an increased risc of icing up. Due to continuous development and updating of VESTAS products, VESTAS reserves the right to change the specifications. __________________________________________________________________________________ Vestas 660 kW Variable Slip Wind Turbine, V47-660 kW and V47-660/200 kW Date: 02-05-00 Class: 1 Item no.: 943111.R4 Page: 19 of 27 11.

V47 Wind Turbine Vestas V47-660 kW with VMP-660kW-690V-50Hz controller. The Vestas V47 wind turbines is available in two versions, V47-660/200 kW and V47-660 kW. The 200 kW generator operates at low wind speeds. This 200 kW generator ensures that the noise from the blades is kept at an absolute minimum. The rotor rotates slowly and an increased power production is achieved. Vestas V47-660 kW wind turbine is a pitch regulated wind turbine, in consequence of which the blades are always pitched in the optimum angle during production as well as stop situations. The generator is a special asynchronous generator with integrated electronics, which is able to operate with a variable slip between 1 % and 10 %. Among the advantages of a pitch regulated wind turbine with variable slip the following should be mentioned: • Optimum production under all wind conditions. • Output is limited to 660 kW. • Power output is smoothed. • No motor start. • Cut in of generator at synchronous speed. • Turbine can be stopped without using the mechanical brake. • Minimising of fluctuations in the mechanical transmission system. 2. The VMP-Controller The wind turbine operates fully automatically by means of the VMP-controller (Vestas Multi Processor controller), which serves the following functions: • Before connection to the grid, the speed of rotation is synchronised to the grid frequency in order to limit the cut-in current. • Thyristor cut-in of the generator to limit the cut-in current. • Cut-in current is lower than nominal current. • Automatic yawing of the nacelle in accordance with the wind direction. • Cut-in and cut-out of the power factor correction. Power factor correction covering no-load consumption of the reactive generator power is standard. • Monitoring of the utility grid in accordance with DEFU report KR111 (Report from Danish Association of Electricity Supply Companies, 1998-04-08). • Monitoring of the operation. • Stop of the turbine in case of faults. • As an option a capacitor assembly for 100 % power factor correction can be bought. The assembly contains impedance coils which protect the capacitors from the overcurrents caused by the 7th and 11th harmonics on the grid (voltage distortion). The VMP-controller consists of a top controller and a ground controller. The top controller is located in the nacelle. The location of the ground controller depends on the choice of tubular tower or lattice tower. The ground controller is outlined on drawing 924785. __________________________________________________________________________________ Electrical Data Vestas V47-660 kW, VMP-690V-50Hz Date: 2. maj 2000 Class: Item no.: 943117.R1 Page: 4 of 18 3. Tubular Tower The ground controller is located at the bottom of the tower, see drawing no. 948606. The grid cables are led through 2 pieces of 160 mm tubes in the foundation and into the grid connection section of the ground controller. 4. Lattice Tower If the turbine is installed on lattice tower, the ground controller is located in a wooden shed between the corner legs of the lattice tower, see drawing 948600. Vestas can supply the wooden shed. The wooden shed must be secured to a concrete foundation, and the grid cables are led through 2 pieces of 160 mm tubes into the grid connection section. 5. System Earthing The transformer must have the lowvoltage gridside connected in star and this starpoint must be earthed, and connected to the earthingsystem of the turbine. It is recommended to make the grid connection as a TN-system, see IEC 364 section 312.2.1. and 413.1.3. In consequence there of, the earthing system of the turbine must be connected to the earthing system of the transformer. The connection can be made either with a separate conductor (e.g. bare copper conductor) or through the neutral conductor in the grid cable, see drawing no. 948636. If the neutral conductor is used, it must be marked with green/yellow tape at both ends and defined as a PE- conductor, according to IEC 364 section 514.3.3. __________________________________________________________________________________ Electrical Data Vestas V47-660 kW, VMP-690V-50Hz Date: 2. maj 2000 Class: Item no.: 943117.R1 Page: 5 of 18 6. Turbine Earthing System/Lightning Protection The system should be made at the same time as the foundation work. The earthing system must be accommodated to local soil conditions. The resistance to neutral earth should normally be no higher than 10 Ω. (In the Netherlands the resistance to neutral earth must be below 2.5 Ω, when the earthing system and concrete reinforcement are connected, see drawing 948678). The earthing system shall be made as a closed ring conductor with earthing rods, see drawing 946056 or 922543. This gives the following advantages: 1. Personnel safety. The ring conductor limits step and contact voltage for persons, staying near the tower foundation in case of a lightning stroke. 2. Operational safety. The earthing rods ensure a steady and low resistance to neutral earth for the whole earthing system. The earthing system is made as follows: 1. Ring conductor in 50 mm2 Cu is established at a distance of 1 m from the foundation and approx. 1 m below ground level. 2. The ring conductor is supplemented with 2 copper coated earthing rods each of 6 m (Ø14). The earthing rods are rammed down on each side of the tower/lattice tower (180° between the earthing rods). 3. The ring conductor is connected to two tower legs or two opposite points on a tubular tower. The ground controller is connected to one of these points, see drawing no. 946056. If the resistance to neutral earth is not sufficiently low, the earthing system can be improved. 1. The two earth rods can be extended to 10 m. 2. Two extra earth rods of each of a length of 10 m can be added (90° between the 4 earth rods). __________________________________________________________________________________ Electrical Data Vestas V47-660 kW, VMP-690V-50Hz Date: 2. maj 2000 Class: Item no.: 943117.R1 Page: 6 of 18 7.

Grid connection The ground controller consists of 5 sections, see drawing 924785. In the bus bar section there is one circuit breaker for the generator (Q8) and one circuit breaker (F30) for the control circuit and light located. The control circuits can be disconnected with one circuit breaker (Q16). Circuit breakers Q8 and Q16 are lockable. When Q8 and Q16 are disconnected there will still be power for the light installation. Beneath the bus bar section the grid connection section is located, please see drawing 922551. The grid cables are conducted through 3 pieces of 110mm tubes in the foundation to the grid connection section in the ground controller. There are four terminals for respectively L1, L2, L3 and PE. The grid cables must be mounted with cable lugs. Two pieces of M12x50 bolts in each terminal are used for mounting the cable lugs. This work has to be carried out by an authorised electrician.

Harmonics are caused by different equipment (e.g. welding machines), which via a transformer is connected to same power supply systems as the wind turbine. Harmonics in the power supply systems reduce the lifetime of the capacitor. The impedance voltage of the transformer and the size of the power factor correction are very important for the acceptable level of harmonics. • If a 800kVA transformer with 4.5% impedance voltage is used together with the 250 kVAr power factor correction, the 5th and 7th harmonics have to be below 3% and 2% respectively. • If a 800kVA transformer with 6% impedance voltage is used together with the 250 kVAr power factor correction, the 5th and 7th harmonics have to be below 3% and 1% respectively. It is recommended to use a 800kVA transformer with 4.5% impedance voltage for a V47-660kW wind turbine. 10. Monitoring of the Grid The generator and the power factor correction will be disconnected if the voltage or the frequency exceeds the limits which are determined in the DEFU report KR111. __________________________________________________________________________________ Electrical Data Vestas V47-660 kW, VMP-690V-50Hz Date: 2. maj 2000 Class: Item no.: 943117.R1 Page: 8 of 18 Nominal phase voltage: UP,nom = 400 V.

The kWh- meter(s) should be located behind a window so that they can be read from outside. The kWh-meter(s) shall be connected to measuring transformers. Following measuring transformers can be used: • Current transformer : class 0.2, 600/5 A or 600/1 A. • Voltage transformers : class 0.2, 400/230 V (line-neutral). 12.
