Imowudi ehambelanayo yendabuko ixhomekeke kwi-parallel manual, edla ixesha kwaye inzima, kwaye iqondo lokuzenzekelayo liphantsi, kwaye ukukhethwa kwexesha elihambelanayo kunobudlelwane obukhulu kunye nezakhono zokusebenza zomqhubi ofanayo. Kukho izinto ezininzi zabantu, kwaye kulula ukuvela i-impulse current enkulu, ebangela umonakalo kwisethi ye-diesel generator kunye nokunciphisa ubomi besethi ye-diesel generator. Ke ngoko, i-Cummins yazisa umgaqo wokusebenza kunye noyilo lwesekethe ye-othomathikhi ehambelanayo yomlawuli we-dizeli generator set. Umlawuli we-synchronous parallel unesakhiwo esilula, ukuthembeka okuphezulu kunye nexabiso eliphezulu lesicelo sobunjineli.
Imeko efanelekileyo yokusebenza ngokuhambelanayo kweseti yejeneretha kunye negridi yamandla okanye iseti yejenereyitha kukuba iimeko ezine zonikezelo lwamandla kumacala omabini esekethe ehambelanayo , umaphuli ziyafana ncam, oko kukuthi, ukulandelelana kwesigaba. yonikezelo lwamandla kumacala omabini kwicala elihambelanayo kunye necala lenkqubo liyafana, i-voltage ilingana, i-frequency ilingana, kwaye umahluko wesigaba ngu-zero.
Ubukho bomohluko wamandla ombane kunye nokwahlukana kwamaza buya kukhokelela kutshintshiselwano oluthile lwamandla asebenzayo kunye namandla asebenzayo kumacala omabini omzuzu woqhagamshelo lwegridi kunye nendawo yoqhagamshelo, kwaye igridi okanye iseti yejenereyitha iya kuchaphazeleka kwinqanaba elithile. Ngokwahlukileyo, ubukho bokwahlukana kwesigaba buya kubangela umonakalo kwisethi ye-generator, eya kubangela i-sub-synchronous resonance kwaye yonakalise i-generator. Ngoko ke, isilawuli esihambelanayo esizenzekelayo esizenzekelayo kufuneka siqinisekise ukuba umahluko wesigaba "ngu-zero" ukugqiba uxhulumaniso lwegridi, kwaye ukwenzela ukukhawulezisa inkqubo yoxhulumaniso lwegridi, vumela uluhlu oluthile lweeyantlukwano zombane kunye nokwahlukana kwamaza.
Imodyuli ye-synchro ithatha inkqubo yokulawula isiphaluka se-analog, ithatha i-classical PI ithiyori yokulawula, ineenzuzo zesakhiwo esilula, isiphaluka esivuthiweyo, ukusebenza kakuhle kwexeshana njalo njalo. Umgaqo-nkqubo wokusebenza ngulo: Emva kokufumana i-synchronous input instruction, i-synchronizer ezenzekelayo ibona izibonakaliso ezimbini ze-AC voltage kwiiyunithi ezimbini eziza kuhlanganiswa (okanye igridi kunye neyunithi), igqibezela uthelekiso lwesigaba kwaye ivelise isignali ye-analog echanekileyo ye-DC. Isignali icutshungulwa yi-PI arithmetic circuit kwaye ithunyelwe kwi-parallel end of the electronic speed controller controller of the engine, ukwenzela ukuba umehluko wesigaba phakathi kweyunithi enye kunye neyunithi (okanye igridi yamandla) iyanyamalala ngexesha elifutshane. Ngeli xesha, emva kokuba isiphaluka sokufumanisa ukuvumelanisa siqinisekisa ukuvumelanisa, isignali yokuvala imveliso igqiba inkqubo yokuvumelanisa.
