Imodi yendabuko yokufana incike ekufana okwenziwa ngesandla, okudla isikhathi futhi okukhathazayo, kanti izinga lokuzenzakalela liphansi, futhi ukukhetha isikhathi sokufana kunobuhlobo obuhle namakhono okusebenza omqhubi ohambisanayo. Kunezici eziningi zabantu, futhi kulula ukubonakala komshini omkhulu wokuphambuka, obangela umonakalo kusethi yejenereyitha yedizili futhi kufinyeze impilo yesethi yejenereyitha yedizili. Ngakho-ke, iCummins yethula isimiso sokusebenza kanye nomklamo wesekethe yesilawuli esihambisanayo esizenzakalelayo sesethi yejenereyitha yedizili. Isilawuli esihambisanayo esihambisanayo sinesakhiwo esilula, ukuthembeka okuphezulu kanye nenani eliphezulu lokusetshenziswa kobunjiniyela.
Isimo esifanele sokusebenza okuhambisanayo kwesethi yejeneretha kanye negridi yamandla noma isethi yejeneretha ukuthi izimo ezine zesimo sokuphakelwa kwamandla kuzo zombili izinhlangothi zesekethe ehambisanayo ，breaker zifana ncamashi, okungukuthi, ukulandelana kwesigaba sokuphakelwa kwamandla kuzo zombili izinhlangothi zohlangothi oluhambisanayo kanye nohlangothi lwesistimu kuyafana, i-voltage iyafana, imvamisa iyafana, kanti umehluko wesigaba ungu-zero.
Ukuba khona komehluko we-voltage kanye nomehluko wemvamisa kuzoholela ekushintsheni okuthile kwamandla asebenzayo kanye namandla asebenzayo kuzo zombili izinhlangothi zomzuzu wokuxhuma kwegridi kanye nendawo yokuxhuma, futhi isethi yegridi noma yejeneretha izothinteka ngezinga elithile. Ngokuphambene nalokho, ukuba khona komehluko wesigaba kuzobangela umonakalo kusethi yejeneretha, okuzobangela ukuzwakala okungaphansi kokuvumelanisa futhi kulimaze ijeneretha. Ngakho-ke, isilawuli esihle esihambisanayo esizenzakalelayo kufanele siqinisekise ukuthi umehluko wesigaba “ungu-zero” ukuqedela uxhumano lwegridi, futhi ukuze kusheshiswe inqubo yokuxhuma kwegridi, kuvumela ububanzi obuthile bomehluko we-voltage kanye nomehluko wemvamisa.
Imojula ye-synchro isebenzisa uhlelo lokulawula isekethe ye-analog, isebenzisa ithiyori yokulawula ye-PI yakudala, inezinzuzo zesakhiwo esilula, isekethe esivuthiwe, ukusebenza okuhle kwesikhashana njalo njalo. Umgomo osebenzayo uthi: Ngemva kokuthola imiyalelo yokufaka ye-synchronous, i-synchronizer ezenzakalelayo ithola izimpawu ezimbili ze-AC voltage kumayunithi amabili okufanele ahlanganiswe (noma igridi neyunithi), iqedela ukuqhathaniswa kwesigaba futhi ikhiqize isignali ye-analog DC elungisiwe. Isignali icutshungulwa yisekethe ye-PI arithmetic bese ithunyelwa ekugcineni okuhambisanayo kwesilawuli sokulawula isivinini se-elekthronikhi senjini, ukuze umehluko wesigaba phakathi kweyunithi eyodwa nenye iyunithi (noma igridi yamandla) unyamalale ngesikhathi esifushane. Ngalesi sikhathi, ngemva kokuba isekethe yokuthola ukuvumelanisa iqinisekisile ukuvumelanisa, isignali yokuvala okukhiphayo iqedela inqubo yokuvumelanisa.
