AC magetsi ekupa system

Iyo AC magetsi ekupa sisitimu yekutaurirana magetsi inverter inoumbwa neakakwira-voltage magetsi ekugovera michina, kutsika-pasi transformer, mafuta jenareta, UPS uye yakaderera-voltage magetsi ekugovera michina. Iyo AC magetsi ekupa system inogona kuve nemhando nhatu dzeAC magetsi masosi: iyo mains simba rinopihwa neiyo substation, iyo yega-ine AC simba rinopihwa nejenareta remafuta, uye iyo backup AC simba rinopihwa neUPS.

(1) Majenareta emafuta Kuti bhatiri rirege kubuda zvakanyanya kunokonzerwa nekudzima kwemagetsi kwenguva refu, Mahofisi ezvekufambiswa kwemashoko kazhinji ane majenareta emafuta. Kana mains simba ravharwa, midziyo yekukurukurirana inogona kushandiswa nedhiziri jenareta set. Muchina wemafuta wakakamurwa kuita wakajairwa oiri muchina uye otomatiki yekutanga oiri muchina. Kana simba rekushandisa rinokanganiswa, jenareta remafuta richatanga kugadzira magetsi. Sezvo iyo mains magetsi emagetsi ane hupfumi uye akavimbika kupfuura iwo ejenareta yemafuta, midziyo yekutaurirana inowanzo fambiswa neiyo mains pasi pemamiriro eiyo mains.

(2) Kuti uve nechokwadi chekuti magetsi ekutaurirana haana kukanganiswa uye kwenguva pfupi-isina, UPS inogona kushandisa static AC isingapindiki magetsi ekupa system, inozivikanwawo seUPS. UPS inowanzo umbwa nemabhatiri, rectifiers, inverters uye static switch. Kana mains ari normal, mains uye inverter yakabatana mukufanana kuti ipe AC simba remidziyo yekutaurirana, uye iyo inverter inogadziriswa ne mains kuti ipe simba kwairi. Panguva imwe, rectifier inochajawo bhatiri, uye bhatiri riri muchimiro chekuyangarara chaji chakafanana. Apo simba rekutengesa rinovhiringidzwa, bhatiri rekuchengetedza rinopa simba re AC kumidziyo yekukurukurirana kuburikidza ne inverter, uye kutendeuka pakati pe inverter uye simba rekutengeserana kunopedzwa ne AC static switch.

(3) AC simba rekugovera pani Chinangwa cheAC simba rekugovera pani ndechekuisa mains simba uye kugovera simba kune akasiyana mitoro yeAC.. Kana mains avhiringwa kana iyo AC voltage isingaite (overvoltage, undervoltage uye kushaya kuenzana), iyo yakaderera-voltage simba rekugovera pani inogona kutumira otomatiki masaini anowirirana.

(4) Connection mode - AC simba rekuchengetedza modhi Iyo AC simba rezviteshi zvakakura zvekutaurirana rinowanzo kupihwa neakakwira-voltage magetsi grid., uye iyo yakazvimirira magetsi shanduko midziyo inogadzirirwa yega. Iyo base station midziyo inowanzorenda magetsi evagari zvakananga. Kuti uvandudze kuvimbika kwemagetsi, zviteshi zviviri zvinowanzounzwa mumagetsi maviri akakwira-voltage nezvikamu zviviri mumahofisi akakosha ekutaurirana hub., uye dzinosumwa nemitsetse yakatsaurirwa, kazhinji imwe yekushandiswa kukuru uye imwe ndeye backup, wobva wadzika pasi kuti upe michina yekutaurirana yakasiyana-siyana uye mwenje kuburikidza netransformer midziyo Equipment, pamusoro pekuva nejenareta yavo yemafuta, kana paita tsaona. Iyo general station inongopinza mutsara mumwechete wemagetsi mains kubva kune grid, uye wozobatana nejenareta remafuta rakazvipa se backup. Zvimwe zviteshi zvidiki zvemahofisi uye zviteshi zvenharembozha zvinongobatana nemagetsi emagetsi (panguva imwechete yakashongedzerwa nebhatiri rine huwandu hwakakwana), uye jenareta remafuta chigadziro chakaiswa mumotokari.
