Umkhiqizi weGeneretha Utshela Ingozi Yokusebenza Kwesigaba

Isethi yejeneretha yedizili: ngenjini, ijeneretha kanye nokwakheka kohlelo lokulawula, okubizwa kanjalo isethi yegenerator. Isethi yejeneretha yedizili luhlobo lwemishini yamandla ethatha injini yedizili njengesihambisi esikhulu futhi ishayela ijeneretha ehambisanayo ukukhiqiza ugesi.Iwumshini wokuphehla ugesi onesiqalo esisheshayo, ukusebenza kahle nokugcinwa kahle, ukutshalwa kwezimali okuncane nokuvumelana nezimo kwemvelo okuqinile.

Uma ijeneretha isebenza ngokujwayelekile, inikeza amandla asebenzayo futhi asebenzayo ohlelweni, futhi i-stator yamanje ibambezela ngemuva kwe-voltage yokugcina nge-Engeli.Lesi simo sibizwa nge-post-operation.Lapho i-excitation current yehla kancane kancane, ijeneretha iyashintsha isuka ekunikezeni amandla asebenzayo iye ekumunceni amandla asebenzayo asuka ohlelweni, kanye ne-stator yamanje ishintsha ukusuka ekubambezelekeni ukuya ku-voltage yetheminali yejeneretha ehamba phambili nge-Engeli.Lesi simo sibizwa ngokuthi ukusebenza kwesigaba esiholayo.Uma ijeneretha ehambisanayo isebenza kusengaphambili, amandla ashukumisayo ancipha kakhulu, futhi amandla okukhiqiza u-Eq ancipha ngokufanele.Kusuka ku-p-power Angle relation, lapho amandla asebenzayo engashintshi, i-Angle yamandla izokhula ngokulinganayo, isilinganiso samandla wesinyathelo sonke sizokwehla ngokuhambisanayo, futhi ukuzinza kwe-generator kuzokwehla.Umkhawulo wayo wokuzinza uhlobene nesilinganiso sesifunda esifushane se-generator, ukusabela kwangaphandle, ukusebenza kwesilawuli se-excitation esizenzakalelayo nokuthi ngabe siyasetshenziswa yini.

Uma kuqhathaniswa nokusebenza kwakamuva, ukuvuza kwe-flux ekugcineni kwe-stator ijeneretha ukwanda ekusebenzeni okuthuthukisiwe.Ikakhulukazi umugqa generator umthwalo uphakeme, isiphetho ukuvuza kazibuthe kukhulu ekusebenzeni evamile, ekupheleni core ingcindezi ibhekisela izinga lokushisa isixhumi ukwanda, kusengaphambili isigaba operation kazibuthe ukuvuza ukuvuza, izinga lokushisa liyaqina.Ngesikhathi sokusebenza kwesigaba sokuhola, i-voltage yokugcina ye-generator iyancipha, futhi i-voltage asizayo iyancipha ngokufanele.Uma idlula i-10%, izothinta ukusebenza kwamandla asizayo.

Ngakho-ke, ukujula kokusebenza kwejeneretha yokuvumelanisa kufanele kunqunywe ngokuhlolwa.Okungukuthi, mangakanani amandla asebenzayo angamuncwa ukuze kugcinwe ukuzinza okumile nokudlulayo kwesistimu, futhi ukukhuphuka kwezinga lokushisa kwengxenye ngayinye akuweqi umkhawulo ukuze kuhlangatshezwane nezidingo zamandla kagesi.

Izingozi ezibangelwa ukusebenza kwesigaba komkhiqizi wejeneretha:

1. Ukwandisa umthwalo osebenzayo we-generator kuzokwenza i-generator ingazinzi, okuzoholela kalula ekusebenzeni okungazinzile kwe-generator ngisho nokuvela kwezingozi ze-oscillation zesistimu.

2. Qhubeka nokunciphisa amandla e-excitation ye-generator futhi ukwandise ukujula kwesigaba esithuthukisiwe se-generator, okungase kuholele ekulahlekelweni kwesenzo sokuvikela i-excitation ye-generator noma ukusebenza okungazinzile kwe-generator.

3. Uma i-generator igijima kusengaphambili, i-stator yamanje iyanda futhi ukushisa kwe-stator kuyanda;Uma ijeneretha isebenza kusenesikhathi, izinga lokuvuza kwe-flux ekupheleni kwe-stator liyakhuphuka, okwenza ukushisa kokugcina kube kubi kakhulu, futhi izinga lokushisa lekhoyili ye-stator ye-generator lizoqhubeka likhuphuka.

4. Uma i-generator isebenza ngaphambi kwesigaba, i-voltage ye-generator outlet iyancishiswa, ukuze i-voltage yebhasi ye-6KV iyancipha.Amandla kagesi aphezulu anokuvikelwa kwe-undervoltage azokwehla;Kuyo yonke imishini kagesi esebenzayo, i-voltage yebhasi iyancipha futhi ukwanda kwamanje, okubangela ukuthi okokusebenza kushise.Ukusebenza isikhathi eside kungalimaza ukufakwa kwensimbi.
