Palibe ubale wachindunji pakati pa ma AC frequency ndi liwiro la injini ya siteshoni yamagetsi yamadzi, koma pali ubale wosalunjika.
Kaya ndi zipangizo zotani zopangira magetsi, zimafunika kutumiza mphamvu ku gridi pambuyo popanga magetsi, kutanthauza kuti, jenereta iyenera kulumikizidwa ku gridi kuti ipange magetsi. Gridi yamagetsi ikakhala yayikulu, kuchuluka kwa ma frequency kumachepetsa, komanso kuchuluka kwa ma frequency kumakhala kokhazikika. Ma gridi amangogwirizana ndi ngati mphamvu yogwira ntchito ili yolinganizidwa. Pamene mphamvu yogwira ntchito yotulutsidwa ndi jenereta ili yayikulu kuposa mphamvu yogwira ntchito yamagetsi, kuchuluka kwa magetsi onse ku gridi yamagetsi kudzawonjezeka. , mosemphanitsa.
Kulinganiza mphamvu yogwira ntchito ndi vuto lalikulu mu gridi yamagetsi. Chifukwa chakuti mphamvu ya ogwiritsa ntchito imasintha nthawi zonse, gridi yamagetsi iyenera kuonetsetsa kuti mphamvu yopangira magetsi ndi kulemera kwa katundu zikuyenda bwino. Kugwiritsa ntchito kwambiri malo opangira magetsi m'makina amagetsi ndikuwongolera ma frequency. Cholinga chachikulu cha magetsi akuluakulu amadzi ndi kupanga magetsi. Poyerekeza ndi mitundu ina ya malo opangira magetsi, malo opangira magetsi ali ndi ubwino wowongolera 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, mphamvu ya nyukiliya, ndi zina zotero, zimasintha mphamvu ya injini pang'onopang'ono. Bola mphamvu yogwira ntchito ya gridi ili bwino, mphamvu yamagetsi imakhala yokhazikika. Chifukwa chake, malo opangira magetsi amadzi ali ndi gawo lalikulu pakukhazikika kwa ma frequency a gridi.
Pakadali pano, malo ambiri opangira magetsi ang'onoang'ono ndi apakatikati mdziko muno ali pansi pa gridi yamagetsi, ndipo gridi yamagetsi iyenera kukhala ndi ulamuliro wonse pa malo opangira magetsi akuluakulu osinthira ma frequency kuti zitsimikizire kukhazikika kwa ma frequency ndi magetsi a gridi yamagetsi. Mwachidule:
1. Gridi yamagetsi imasankha liwiro la mota. Tsopano timagwiritsa ntchito ma mota ogwirizana popanga magetsi, zomwe zikutanthauza kuti liwiro la kusintha ndi lofanana ndi la gridi yamagetsi, kutanthauza, kusintha 50 pa sekondi. Pa jenereta yomwe imagwiritsidwa ntchito pafakitale yamagetsi yotentha yokhala ndi ma electrode awiriawiri okha, ndi ma revolution 3000 pamphindi. Pa jenereta yamagetsi yamadzi yokhala ndi ma electrode awiriawiri a n, ndi ma revolution 3000/n pamphindi. Gudumu lamadzi ndi jenereta nthawi zambiri zimalumikizidwa pamodzi ndi njira yotumizira yokhazikika, kotero tinganene kuti imadziwitsidwanso ndi kuchuluka kwa gridi.
2. Kodi ntchito ya makina osinthira madzi ndi yotani? Sinthani mphamvu ya jenereta, kutanthauza mphamvu yomwe jenereta imatumiza ku gridi. Nthawi zambiri pamafunika mphamvu inayake kuti jenereta isunge liwiro lake lovomerezeka, koma jenereta ikalumikizidwa ku gridi, liwiro la jenereta limatsimikiziridwa ndi kuchuluka kwa gridi, ndipo nthawi zambiri timaganiza kuti kuchuluka kwa gridi sikusintha. Mwanjira imeneyi, mphamvu ya jenereta ikapitirira mphamvu yofunikira kuti isunge liwiro lovomerezeka, jenereta imatumiza mphamvu ku gridi, ndipo mosemphanitsa imayamwa mphamvu. Chifukwa chake, injini ikapanga mphamvu yokhala ndi katundu wambiri, ikachotsedwa pa sitima, liwiro lake lidzawonjezeka mwachangu kuchokera pa liwiro lovomerezeka mpaka kangapo, ndipo n'zosavuta kuyambitsa ngozi yothamanga!
3. Mphamvu yopangidwa ndi jenereta idzakhudzanso kuchuluka kwa magetsi a gridi, ndipo chipangizo chamagetsi chamadzi nthawi zambiri chimagwiritsidwa ntchito ngati chipangizo chowongolera ma frequency chifukwa cha kuchuluka kwa mphamvu yoyendetsera magetsi.
