Iyo yechinyakare parallel modhi inotsamira pane yemanyorero parallel, iyo inotora nguva uye inorema, uye dhigirii re automation yakaderera, uye sarudzo yeinoenderana nguva ine hukama hukuru nehunyanzvi hwekushanda hweanoshanda anofanana. Pane zvakawanda zvezvinhu zvevanhu, uye zviri nyore kuratidzika hombe impulse ikozvino, izvo zvinokonzeresa kukuvadza kune dizeli jenareta set uye kupfupisa hupenyu hweiyo dhiziri generator set. Naizvozvo, Cummins inosuma iyo yekushanda musimboti uye dhizaini dhizaini yeiyo otomatiki synchronous parallel controller yedhiziri jenareta set. Iyo synchronous parallel controller ine chimiro chakareruka, kuvimbika kwakanyanya uye yakakwirira engineering application kukosha.
Mamiriro akakodzera eiyo synchronous parallel mashandiro ejenareta seti uye gidhi remagetsi kana jenareta seti ndeyekuti mana ehurumende mamiriro emagetsi pamativi ese ari maviri eparallel circuit, breaker yakafanana chaizvo, kureva kuti, kutevedzana kwechikamu. yesimba rekupa pamativi ese ari maviri edivi rakafanana uye chikamu chehurongwa chakafanana, voltage yakaenzana, frequency yakaenzana, uye mutsauko wechikamu i zero.
Kuvapo kwekusiyana kwevoltage uye frequency musiyano kunotungamira kune imwe shanduko yesimba rinoshanda uye rinoshanda simba pamativi ese eiyo grid yekubatanidza nguva nenzvimbo yekubatanidza, uye gidhi kana jenareta seti ichakanganisika kune imwe nhanho. Kusiyana neizvi, kuvepo kwekusiyana kwechikamu kunokonzeresa kukuvadza kune jenareta seti, izvo zvinokonzeresa sub-synchronous resonance uye kukuvadza jenareta. Naizvozvo, yakanaka otomatiki synchronous parallel controller inofanirwa kuve nechokwadi chekuti mutsauko wechikamu "zero" kupedzisa iyo grid yekubatanidza, uye kuti ikurumidze iyo grid yekubatanidza maitiro, bvumidza humwe huwandu hwekusiyana kwemagetsi uye frequency mutsauko.
Iyo synchro module inotora iyo analog yedunhu control system, inotora yekare PI control theory, ine zvakanakira chimiro chakareruka, dunhu rakakura, kuita kwakanaka kwenguva pfupi uye zvichingodaro. Musimboti wekushanda ndewekuti: Mushure mekugamuchira iyo synchronous yekuraira, iyo otomatiki synchronizer inoona maviri AC voltage masaini pamayuniti maviri kuti abatanidzwe (kana gidhi neyuniti), inopedzisa kuenzanisa kwechikamu uye inogadzira yakagadziriswa analog DC chiratidzo. Chiratidzo chinogadziriswa nePI arithmetic circuit uye chinotumirwa kumagumo akafanana emagetsi ekugadzirisa kukurumidza kwejini, kuitira kuti mutsauko wepakati pakati peimwe unit uye imwe unit (kana kuti girasi remagetsi) inonyangarika munguva pfupi. Panguva ino, mushure meiyo synchronization yekuona wedunhu inosimbisa kuwiriranisa, iyo inobuda yekuvhara chiratidzo inopedzisa kuwiriranisa maitiro.
