Sisitemu yo kugenzura imikorere ibangikanye
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. (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 za seti ebyiri zitanga amashanyarazi ni zimwe.
4. Icyiciro cyurukurikirane rwibice bibiri bitanga amashanyarazi birahuye.
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 guhurizwa hamwe nikimwe nikindi gice, icyerekezo cya metero cyerekana cyerekana hejuru ya kare kare hagati, kandi itara rya sinhron riba ryijimye. Iyo itandukanyirizo ryicyiciro hagati yikintu kigomba guhurizwa hamwe nikindi gice kinini, metero ya syncronike yerekana umwanya uri hagati, kandi itara rya syncronique riri kuri iki gihe. Iyo metero ya syncronike yerekana izunguruka ku isaha, byerekana ko inshuro ya generator ikora irenze iyindi gice. Umuvuduko wa generator ya seti igomba kugabanywa, kandi umuvuduko wamashanyarazi ya standby ugomba kwiyongera mugihe icyerekezo cyisaha kizunguruka kumasaha. Iyo icyerekezo cyisaha kizunguruka gahoro gahoro mucyerekezo cyisaha kandi icyerekezo cyegereye ingingo imwe, icyuma cyumuzunguruko cyigice cyo guhurizwa hamwe kirahita gifungwa ako kanya, kugirango ibice bibiri bitanga amashanyarazi bibangikanye. Kuruhande-rwakuweho 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 ibintu bya cassette imbere mumeza ya syncronique, bitagaragaza neza imiterere yimvange.
2. 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:
