Ukuvikelwa kombani kwezinhlelo zamandla omoya Umbani yinto eqinile yokukhishwa komkhathi ende, engabangela ngokuqondile noma ngokungaqondile izinhlekelele ezikhungweni eziningi ezingaphezulu. Njengezinkundla eziphakeme ngaphezu komhlaba, izinjini zomoya zichayeka emkhathini isikhathi eside futhi zivame ukutholakala ezindaweni ezivulekile, lapho zisengozini yokushaywa umbani. Uma kwenzeka umbani ushaya, amandla amakhulu akhishwa umbani azodala umonakalo omkhulu kuma-blades, izinto zokudlulisa amandla, ukukhiqiza ugesi kanye nemishini yokuguqula kanye nohlelo lokulawula lwenjini yomoya, okuholela ezingozini zokunqamuka kwamayunithi kanye nokulahlekelwa okukhulu kwezomnotho. Amandla omoya angavuseleleka futhi angamandla ahlanzekile. Ukukhiqizwa kwamandla omoya kuwumthombo wamandla onezimo zokuthuthukiswa kwesikali esikhulu kakhulu. Ukuze uthole amandla omoya engeziwe, umthamo owodwa we-turbine yomoya uyakhula, ukuphakama kwefeni kuyanda nokuphakama kwehabhu nobubanzi be-impeller, futhi ingozi yombani iyanda. Ngakho-ke, isiteleka sombani sekuyinhlekelele yemvelo eyingozi kakhulu ekusebenzeni okuphephile kwe-wind turbine emvelweni. Uhlelo lwamandla omoya lungahlukaniswa ngamazinga amaningana ezindawo zokuvikela ngokuvumelana nokuvikelwa kombani kusuka ngaphandle kuya ngaphakathi. Indawo engaphandle kakhulu yindawo ye-LPZ0, okuyindawo eqondile yombani futhi enobungozi obukhulu. Lapho ingaphakathi, ingozi iyancipha. Indawo ye-LPZ0 yakhiwe ngokuyinhloko idivayisi yokuvikela umbani yangaphandle, ukhonkolo oqinisiwe kanye nesakhiwo sepayipi lensimbi ukuze kwakhiwe ungqimba lokuvimbela. I-Overvoltage ingena kakhulu emgqeni, kungenxa yomvikeli ohlinzayo ukuvikela imishini. Uchungechunge lwe-TRS izivikeli ezikhethekile zokuhlinza zamasistimu amandla omoya zisebenzisa isici sokuvikela ukugcwala ngokweqile okunezici ezinhle kakhulu ezingaqondile. Ngaphansi kwezimo ezijwayelekile, umvikeli ohlinzayo usesimweni sokumelana okuphezulu kakhulu, futhi amandla avuzayo acishe abe ziro, ukuze kuqinisekiswe ukunikezwa kwamandla okuvamile kwesistimu yamandla omoya. Lapho isistimu ikhuphuka ngokweqile, isistimu yamandla omoya echungechunge lwe-TRS yomvikeli ohlinzayo ngokushesha ekuqhutshweni kwesikhathi se-nanosecond, ikhawulela i-amplitude ye-overvoltage ekuphepheni kwezinto zokusebenza ngaphakathi kwendawo yokusebenza, ngesikhathi esifanayo ikhiphe amandla okusebenza adluliselwe emhlabathini, bese ihlinza isivikelo futhi ngokushesha esimweni sokumelana okuphezulu, okungaphazamisi umsebenzi ojwayelekile wesistimu yamandla omoya.
