Ma AC frequency sakugwirizana mwachindunji ndi liwiro la injini ya siteshoni yamagetsi yamadzi, koma amagwirizana mwachindunji.
Kaya ndi zipangizo zotani zopangira magetsi, ndikofunikira kutumiza mphamvu zamagetsi ku gridi yamagetsi mutapanga mphamvu zamagetsi, kutanthauza kuti, jenereta iyenera kulumikizidwa ku gridi kuti ipange mphamvu. Ikalumikizidwa ku gridi, imalumikizidwa ndi gridi yamagetsi yonse, ndipo ma frequency kulikonse mu gridi yamagetsi ndi ofanana. Gridi yamagetsi ikakhala yayikulu, kuchuluka kwa ma frequency kumakhala kochepa komanso ma frequency amakhala okhazikika. Komabe, ma frequency a gridi yamagetsi amangogwirizana ndi ngati mphamvu yogwira ntchito ili yolinganizidwa. Pamene mphamvu yogwira ntchito yotulutsidwa ndi jenereta imakhala yayikulu kuposa mphamvu yogwira ntchito yamagetsi, ma frequency onse a gridi yamagetsi adzakwera, ndipo mosemphanitsa.
Kulinganiza mphamvu yogwira ntchito ndi nkhani yaikulu pa gridi yamagetsi. Chifukwa mphamvu ya ogwiritsa ntchito imasintha nthawi zonse, gridi yamagetsi iyenera kuonetsetsa kuti mphamvu yopangira magetsi ndi kulemera kwa katundu zikuyenda bwino. Cholinga chachikulu cha siteshoni yamagetsi yamadzi mu dongosolo lamagetsi ndikusintha ma frequency. Zachidziwikire, mphamvu yayikulu yamadzi ya Three Gorges imagwiritsidwa ntchito kwambiri popanga magetsi. Poyerekeza ndi mitundu ina ya malo opangira magetsi, malo opangira magetsi amadzi ali ndi ubwino wosintha ma frequency. Turbine yamadzi imatha kusintha liwiro mwachangu, zomwe zimatha kusinthanso mwachangu mphamvu yogwira ntchito komanso yogwira ntchito ya jenereta, kuti ilinganize mwachangu mphamvu ya gridi, pomwe mphamvu ya kutentha ndi mphamvu ya nyukiliya zimasinthasintha mphamvu ya injini pang'onopang'ono. Bola mphamvu yogwira ntchito ya gridi yamagetsi ili bwino, mphamvu yamagetsi imakhala yokhazikika. Chifukwa chake, malo opangira magetsi amadzi amathandizira kwambiri kukhazikika kwa ma frequency a gridi yamagetsi.
Pakadali pano, malo ambiri opangira magetsi ang'onoang'ono ndi apakatikati ku China ali pansi pa gridi yamagetsi. Gridi yamagetsi iyenera kukhala ndi ulamuliro pa malo opangira magetsi akuluakulu osinthira ma frequency, kuti zitsimikizire kuti ma frequency ndi voltage ya gridi yamagetsi ndi olimba. Mwachidule:
1. Gridi yamagetsi imatsimikiza liwiro la mota. Tsopano timagwiritsa ntchito ma mota ogwirizana popanga magetsi, kutanthauza kuti, kusintha kwa magetsi ndi kofanana ndi kwa gridi yamagetsi, kutanthauza, nthawi 50 mu sekondi imodzi. Pa jenereta yamagetsi yotentha yokhala ndi ma electrode awiriawiri okha, imazungulira ma revolutions 3000 pamphindi. Pa jenereta ya hydropower plant yokhala ndi ma electrode awiriawiri, imazungulira 3000 / N pamphindi. Turbine yamadzi ndi jenereta nthawi zambiri zimalumikizidwa pamodzi kudzera mu njira yotumizira yokhazikika, kotero tinganene kuti imatsimikiziridwanso ndi ma frequency a gridi yamagetsi.
2. Kodi njira yoyendetsera madzi imagwira ntchito yanji? Sinthani mphamvu yotulutsa jenereta, kutanthauza mphamvu yotumizidwa ndi jenereta ku gridi yamagetsi. Nthawi zambiri, mphamvu inayake imafunika kuti jenereta isunge liwiro lake lovomerezeka, koma jenereta ikalumikizidwa ku gridi, liwiro la jenereta limatsimikiziridwa ndi kuchuluka kwa gridi. Pakadali pano, nthawi zambiri timaganiza kuti kuchuluka kwa gridi sikunasinthe. Mwanjira imeneyi, mphamvu ya jenereta ikapitirira mphamvu yofunikira kuti isunge liwiro lovomerezeka, jenereta imatumiza mphamvu ku gridi ndipo imatenga mphamvu m'malo mwake. Chifukwa chake, injini ikapanga mphamvu pansi pa katundu wolemera, ikachotsedwa, liwiro lake lidzawonjezeka mwachangu kuchokera pa liwiro lovomerezeka mpaka kangapo, zomwe zimapangitsa ngozi zouluka!
3. Mphamvu yopangidwa ndi jenereta idzakhudzanso ma gridi, ndipo mayunitsi amagetsi amadzi nthawi zambiri amagwiritsidwa ntchito ngati mayunitsi osinthira ma frequency chifukwa cha kuchuluka kwa malamulo.
