Jenareta Mugadziri Kunze-kwedanho Dziviriro

Jenereta stator pasi chikanganiso chekudzivirira chejenareta stator imwe-chikamu chepasi chidziviriro chekudzivirira, katatu neimwe yakakosha zero sequence voltage uye harmonic voltage yezvikamu zviviri, yekutanga harmonic zero sequence voltage yekudzivirira muchina muswe unopera kusvika 95% nharaunda ye stator inotenderera imwe- chikamu chekumisa kukanganisa, iyo inoratidzwa simba patani mu zero sequence voltage musimboti, panguva t1 (3 s) nyora kunze kwekuita magineti mumhinduro;Yechitatu harmonic voltage inodzivirira stator inotenderera imwe-chikamu chekudzika chikanganiso kubva kumuswe kusvika 30% yemagumo emuchina, iyo inoumbwa nejenareta isina kwayakarerekera point uye musimboti wechitatu harmonic wekupera kwemuchina, uye unoshanda chiratidzo kuburikidza nenguva t2 (5s).Ose ari maviri anoumba 100% stator grounding dziviriro.Dziviriro ine PT wire break lock.

Stator tendeuka kushandura kudzivirira kwejenareta

Dziviriro inoumbwa nelongitudinal zero-sequence voltage uye isina kunaka kutevedzana dhigirii yekutadza kurongedza.Iyo PT disconnection blocking chiyero inoiswa sechidziviriro chikuru che-inter-turn, inter-phase short circuit uye stator winding opening welding mukati mejenareta.Icho chinokanganisa chikamu chisina kunaka chekutevedzana kwegwara chinoona iyo longitudinal zero sequence voltage criterion inoona iyo longitudinal 3U0 inobuda ne 3PT yakavhurika katatu inomonereka iyo yakabatana zvakananga kune jenareta isina kwayakarerekera asi isina kudzika kuburikidza nekuona iyo yakaipa kutevedzana simba rejenareta.Chengetedzo chiito chinomira zvachose.

Jenereta mugadziri kunze-kwe-nhanho kudzivirira

Dziviriro inoshandisa matatu impedance zvinhu, kuburikidza neiyo impedance trajectory shanduko kuona huwandu hweanotsvedza danda uye kuona nzvimbo yeoscillation centre.Panyaya yekukanganisa kwepfupi, system oscillation, voltage circuit break, nezvimwewo, kudzivirira kubva kumisoperation.Chengetedza chiito chese pane chiratidzo;Kana iyo oscillation centre iri mukati mejenareta uye transformer boka, chikamu chekudzivirira ini chinotanga kutumira murairo wekufamba kuburikidza neT1 (0.5s), uye chiito ndechekudzima magineti.Kana iyo oscillation centre iri kunze kwejenereta-transformer seti, chikamu chekudzivirira II chinotangwa kuratidza kuburikidza neT2 (2S).Dziviriro yakashongedzerwa neyezvino yekuvhara mudziyo kuti ive nechokwadi chekuti ikozvino haipfuure yakayerwa kunze-ye-nhanho yekutyora ikozvino yedunhu redunhu kana redunhu radzimwa.

Low frequency accumulative protection

Low frequency accumulation protective reaction system frequency kudzikisa kuwedzera kwekuita kweiyo turbine turbine, dziviriro inoumbwa neanonzwa frequency relay uye counter, kukiya yekubuda wedunhu breaker anobatsira mabikirwo (kureva, iyo yakaderera frequency jenareta inobuda yenguva yekuunganidza kuchengetedza zvakare. kurega kumhanya), iyo cumulative system frequency yakaderera pane 47.5 Hz frequency kuseta nguva, kana iyo yakatarwa kukosha kweiyo yakazara nguva kusvika 3000 masekonzi, Signal inotumirwa mushure me30 masekondi kunonoka.Chishandiso chinogona kutariswa munguva chaiyo panguva yekushanda: kukosha kwekugara, frequency F uye yakaunganidzwa nguva yekuratidzira.Differential dziviriro jenareta uye transformer boka, differential kudzivirira transformer uye yakakwirira musiyano kudzivirirwa ndiyo huru kudzivirira interphase pfupi redunhu kukanganisa akadzivirirwa zvinoriumba, kushandisa reshiyo akabhureki musimboti.Kukanganisa kwekunze-kwe-zone kunogona kuvimbika kusaenzana ikozvino kunokonzerwa nekusaenderana kweCT maitiro ega ega, uye in-zone chengetedzo yekukanganisa inogona kuita zvine hanya.Kuti udzivise kudzivirira misoperation pasi petransformer inrush ikozvino, dziviriro inotora yechipiri harmonic kukiya.Kudzivirirwa kunoshongedzerwa nebasa rekuvhara kusiyanisa kuyerera kweyero pasina yechipiri harmonic wave, uye chikanganiso chinogona kubviswa ipapo ipapo kana musiyano wezvino unosvika pakukosha kwekuisa.Dziviriro ine CT mutsara wekuvhara yekuvhara basa (isina kunyatso shandiswa).CT mutsara wekuputsa kusarura kwakafanana nejenareta kusiyana kwekudzivirira.

Guangxi Dingbo Power Equipment Manufacturing Co., Ltd. yakavambwa muna 2006, inogadzira dhiziri jenareta muChina, iyo inobatanidza dhizaini, kugovera, kutumira uye kugadzirisa dhiziri jenareta.Chigadzirwa chinofukidza Cummins, Perkins, Volvo, Yuchai, Shangchai, Deutz , Ricardo, MTU, Weichai etc. nesimba siyana 20kw-3000kw, uye vave yavo OEM fekitari uye tekinoroji centre.
