Ibisobanuro ku bicuruzwa

Ubwa mbere, ni ubuhe buryo bukenewe bwo gukora parallel ya generator?
Inzira yose yo gushyira generator yashizwe mubikorwa byitwa parallel operation. Amashanyarazi ya mbere azakora, voltage yoherejwe muri bisi, nandi mashanyarazi yashizweho nyuma yo gutangira, hamwe na generator yabanjirije, bigomba kuba mugihe cyo gusoza, amashanyarazi ntagomba kugaragara nkimpanuka zangiza, shaft ntabwo biterwa n'ingaruka zitunguranye. Nyuma yo gufunga, rotor igomba gukururwa byihuse muri sync. (ni ukuvuga, umuvuduko wa rotor uhwanye n'umuvuduko wagenwe) Kubwibyo, moteri ya generator igomba kuba yujuje ibi bikurikira:
1. Agaciro keza na flake ya generator yashizeho voltage igomba kuba imwe.
2. Icyiciro cya voltage ya generator ebyiri nimwe.
3. Inshuro zamashanyarazi abiri ni imwe.
4. Urutonde rwicyiciro cya generator ebyiri zirahoraho.

Icya kabiri, ni ubuhe buryo bwo guhuza ibice bya generator? Nigute ushobora gukora icyarimwe icyarimwe?
Quasi-synchronous nigihe nyacyo. Hamwe na quasi-syncronisme yuburyo bubangikanye, generator yashyizeho voltage igomba kuba imwe, inshuro nimwe kandi icyiciro kirahoraho, gishobora gukurikiranwa na voltmeter ebyiri, metero ebyiri zumurongo hamwe nibipimo simusiga kandi bidahuje byashyizweho kuri disiki ya syncronous, hamwe nintambwe igereranya ibikorwa nibi bikurikira:
Imizigo yimikorere ya generator imwe yarafunzwe, na voltage yoherejwe mukabari, mugihe ikindi gice kiri mumwanya uhagaze.
Funga intangiriro yigihe kimwe, uhindure umuvuduko wa generator yashyizweho, kugirango iringanire cyangwa yegereye umuvuduko wa syncronique (itandukaniro ryinshuro hamwe nikindi gice mugice cyizunguruka), hindura voltage yumuriro wa generator uhagaze, ku buryo yegereye voltage yandi mashanyarazi yashizweho, mugihe inshuro na voltage bisa, umuvuduko wo kuzenguruka kumeza ya syncronique ugenda gahoro kandi gahoro, kandi urumuri rwerekana narwo rumurika kandi rwijimye icyarimwe; Iyo icyiciro cyigice cyo guhuzwa ari kimwe nicy'ikindi gice, icyerekezo cya metero cyerekana icyerekezo cyo hejuru kare hagati, kandi itara rya sinhron riba ryijimye. Iyo itandukanyirizo ryicyiciro hagati yikintu kigomba guhurizwa hamwe ikindi gice kinini, metero ya syncronique yerekana umwanya uri hagati, kandi itara rya syncronique riri kuri iki gihe. Iyo metero ya syncronike yerekana izenguruka isaha, byerekana ko inshuro ya generator ya syncron iri hejuru kurenza iyindi gice. Umuvuduko wa generator ya seti igomba kugabanywa, kandi umuvuduko wa generator ya seti igomba kwiyongera mugihe icyerekezo cyisaha kizunguruka ku isaha. Iyo icyerekezo cyisaha kizunguruka gahoro gahoro mucyerekezo cyisaha kandi icyerekezo cyegereye ingingo imwe, icyuma cyumuzunguruko cyikintu kigomba guhuzwa gihita gifungwa ako kanya, kugirango ibice bibiri bitanga amashanyarazi bibangikanye. Kuruhande-rwacukuwe na chronografi yahinduwe hamwe na chronoswitches.

Icya gatatu, ni iki gikwiye kwitabwaho mugihe ukora quasi-synchronous juxtaposition ya generator yashizweho?
Quasi-syncronal parallel nigikorwa cyintoki, niba ibikorwa bigenda neza kandi uburambe bwumukoresha bufite umubano ukomeye, kugirango wirinde guhuza ibice bitandukanye, imanza eshatu zikurikira ntizemewe gufungwa.
1. Iyo icyerekezo cyimbonerahamwe isa nikintu cyo gusimbuka ibintu, ntabwo byemewe gufunga, kuko hashobora kubaho cassette phenomenon imbere mumeza ya syncronique, itagaragaza neza imiterere yimvange.
2. Iyo imbonerahamwe ya syncronique izunguruka vuba, byerekana ko itandukaniro ryinshuro hagati yumurongo wa generator nizindi seti ya generator ari nini cyane, kuko igihe cyo gufunga icyuma cyumuzingi kiragoye kubyitwaramo, akenshi icyuma cyumuzunguruko ntikiba gifunze kuri gihe kimwe, ntabwo rero byemewe gufunga muriki gihe.
3. Niba isaha yerekana isaha ihagarara icyarimwe, ntabwo byemewe gufunga. Ibi ni ukubera ko niba inshuro imwe muri generator ishyiraho impinduka zitunguranye mugihe cyo gusoza, birashoboka gukora icyuma cyumuzunguruko hafi yikintu kidahuje.

Icya kane, nigute ushobora guhindura imbaraga zinyuranye zingingo zingana?
Mugihe amashanyarazi abiri adafite icyo akora, hazabaho itandukaniro rya frequency na voltage itandukaniro hagati yamaseti yombi. Kandi ku gikoresho cyo gukurikirana ibice byombi (ammeter, metero yimbaraga, metero yingufu za metero), imiterere yimbaraga zinyuma zigaragara, imwe nimbaraga zinyuranye ziterwa numuvuduko udahuye (frequency), indi nimbaraga zinyuranye zatewe nuburinganire. voltage, ihinduwe kuburyo bukurikira:
