Chidwi chiyenera kuperekedwa ku vuto la 90% kulephera kwa 1.5MW mayunitsi odyetsedwa kawiri.

Wind Power Network News: Makina osinthira ndiye njira yayikulu yamagetsi yama turbine yamphepo.Ntchito yake ndikugwirizanitsa jenereta ndi gululi, ndikusintha mphamvu zopanda mphamvu za AC zotulutsa mphamvu ndi jenereta mu mphamvu yafupipafupi ya AC mphamvu kupyolera mu makina osinthira ndikutumiza ku gridi.Dongosolo lake lozizira limapereka kutentha kwa mphamvu yamagetsi mu kabati yosinthira kuti kutentha kwa magetsi kukhale mkati mwazonse.

Masiku ano, makina osinthira a unit 1.5MW, omwe akhala akugwira ntchito kwa zaka zambiri, ali ndi ntchito zosiyanasiyana monga kutentha kwambiri kwa intaneti, chinyezi chambiri mu kabati yosinthira, kutsekeka kwa gawo la inverter, kuwonongeka pafupipafupi kwa contactor inverter fyuluta, ndi kusakhazikika kwa chizindikiro cha inverter.Mavuto, mavutowa angapangitse makina opangira mphepo kuti azigwira ntchito ndi mphamvu zochepa, kapena kuyambitsa ngozi zoopsa zachitetezo monga kuwomba ma modules ndi makabati oyaka.

Mu gawo la 1.5MW lodyetsedwa kawiri, makina osinthira pafupipafupi ndi amodzi mwazinthu zazikulu zagawo.Ntchito yake yayikulu ndikuzindikira kuwongolera ndi kulumikizana kwa gridi ya mphamvu yotulutsa ya turbine yamphepo mwa kusangalatsa jenereta.Zikumveka kuti patatha zaka zambiri zautumiki, kukwera mtengo wogula ma module amagetsi a 1.5MW odyetsedwa kawiri, kuwonongeka pafupipafupi kwa ma inverter filter contactors, ndi kulephera kwa Converter kwavutitsa eni magetsi amphepo mobwerezabwereza chifukwa chakuchepetsa mtengo ndikuwonjezeka. kuchita bwino.NS.

Kapangidwe ka makina opangira magetsi opangidwa ndi mphepo mowirikiza kawiri.

Mlandu 1: Kusintha komweko kuti mukwaniritse kusintha kosasinthika kwa ma module amphamvu a inverter

Popeza mtengo wogulira ma module obwera kunja ndi wokwera, kodi tingaganizire kuwasintha ndi ma module apakhomo amtundu womwewo?Pankhani imeneyi, katswiri luso luso la Beijing Jinfeng Huineng Technology Co., Ltd. ananena kuti kwenikweni, makampani zoweta kale anaika maganizo amenewa kuchita.Zikumveka kuti mu kamangidwe ka mankhwala m'malo kwa gawo inverter wa 1.5MW awiri kudyetsedwa wagawo, kukula ndi mawonekedwe tanthauzo la zoweta mankhwala mphamvu wagawo akhala kwathunthu zogwirizana ndi choyambirira wagawo mphamvu.Komanso, mankhwalawa ayesedwa mwamphamvu ndikutsimikiziridwa, zizindikiro zonse zogwirira ntchito zimakwaniritsa zofunikira zogwiritsira ntchito, ndipo teknoloji ndi khalidwe lafika pamlingo wokhwima.

Kuchokera pa zojambula zojambula kupita ku mphamvu yeniyeni yeniyeni, kukula kwake ndi mawonekedwe a mawonekedwe a chinthu chodzipangira chokha chimagwirizana ndi mphamvu yapachiyambi, ndipo ntchitoyo imakhala yokhazikika komanso yodalirika.

Tinganene kuti m'malo m'malo mwangwiro amathetsa mavuto a nthawi yaitali zogula mkombero ndi mkulu kukonza ma modules mphamvu kunja.Ndikoyenera kutchula kuti zinthu zomwe zilipo panopa zimatha kukwaniritsa ma module angapo.

Komanso, mu kusintha wapadera wa mayunitsi 1.5MW awiri kudyetsedwa, Jinfeng Hui Mphamvu pafupifupi anapanga ntchito luso kusintha kuphimba zitsanzo zambiri za kusefa kukhathamiritsa, mabuku kasamalidwe Converter, etc., mogwira kuchepetsa pafupipafupi Converter kulephera mlingo ndi kuonetsetsa chitetezo cha gulu.Odalirika ntchito.

Mlandu 2: Kulephera kwa 90%!Njira yothetsera kutentha kwakukulu kosinthira ndi kusalowerera kwa stator contactor

Kuphatikiza pa ma frequency converters, otembenuza omwe amatumizidwa kunja amagwiritsidwanso ntchito kwambiri m'magawo odyetsedwa kawiri a 1.5MW.M'chilimwe, kulephera kwa kutentha kwa otembenuza ena kumakhala pafupifupi 90% ya kulephera kwapachaka kwa otembenuza, zomwe zimakhudza kwambiri ntchito yotetezeka ya makina opangira mphepo.

The misalignment wa Converter stator contactor ndi chimodzi mwa mavuto ambiri panopa.Kusokonezeka kwa pulogalamu ya olamulira kapena kuwonongeka kwa hardware kudzachititsa kuti mphepo yamkuntho ikhale yophatikizika mu gridi yamagetsi mumkhalidwe woyimilira ndikuwotcha zigawo zikuluzikulu za converter.

Poganizira zolakwika ziwiri zomwe zili pamwambazi za kutentha kwakukulu ndi kuyamwa mwangozi, njira yothetsera vutoli yomwe ilipo panopa ndi kuthetsa vuto la kutentha kwambiri pogwiritsa ntchito nsanja kuti apange utsi wokwera;mabasi a DC samayimitsidwa kale, cholumikizira cha stator sichitsekedwa, ndi stator The contactor imachotsedwa pamene itaya mphamvu kuteteza stator contactor kuti isakokedwe molakwika, kuti athetse vuto la stator contactor kukhala. kukokedwa ndi kuwonongeka kwa bolodi loyang'anira dera.
