Kudyidzana Kwemajenareta

Reverse magetsi ekugadzirisa anonziwo simba rekutungamira kugadzirisa.Kazhinji kutaura, iyo simba kutungamira kwe jenareta inofanira kunge iri kutungamira kwejenereta kubhazi, asi kana jenareta inorasikirwa nemagnetism kana chimwe chikonzero chejenareta, jenareta inogona kushanduka kuita motokari yekushanda, kureva, tora simba rinoshanda kubva muhurongwa.Iri ndiro simba rinopikisa.Kana simba rekuchinjika rasvika pane imwe kukosha, chiito chekugadzirisa jenareta, kana chiito chekuratidza kana chiito chekugumburwa.

Iyo grid-yakabatana turbogenerator inoshanda seyakafanana mota mushure mekunge vheji huru ye turbine yakavharwa: inotora simba rinoshanda uye inokwevera iyo turbine rolling, iyo inogona kutumira reactive simba kune system.Nekuti vharuvhu hombe yeturbine yemhepo yakavharwa, blade yemuswe weturbine inopokana neinosara mutsi uye inoita kurasikirwa kwekuputika, uko kunokuvadzwa nekupisa mukati mekushanda kwenguva refu.Gasi nemvura turbine zvakare injodzi huru kune vanotanga movers.Jenareta reverse simba rekugadzirisa chikuru chekugadzirisa steam turbine kubva mukukuvadza.

Kuseta kuverenga kweiyo steam turbine inverse simba rekugadzirisa ndeyekuona simba rekushanda Pdz uye chiito kunonoka T chekugadzirisa.

1. Simba rekuita rePdz set turbogenerator inverse simba rekugadzirisa simba rekuita rinogona kuverengerwa maererano neformula inotevera: Pdz = (Krel * P1)/η Pdz- Inverse simba rekuchengetedza simba rekushanda simba Krel- kuvimbika coefficient, tora 0.8 P1- simba rinoshandiswa ne turbine kuchengetedza synchronous kutenderera kumhanya mushure mekunge vharafu huru yavharwa, saizi yesimba iri inoenderana neiyo turbine chimiro uye kugona, Zvakare zvine chekuita nechimiro cheiyo main steam system ye turbogenerator (pipeline chimiro uye kana paine bypass. pombi, nezvimwewo), kazhinji tora 1.5~2% yesimba rakayerwa η- kushanda zvakanaka kana jenareta ichikweva turbogenerator kutenderera, tora 0.98~0.99 saka: Pdz≈ (1.2~1.6%) PN PN- iyo yakayerwa simba re jenareta.Mukuita, Pdz = inogona kuva 1-1.5% PN.

2. chiito kunonoka jenareta inverse simba rekugadzirisa chiito kunonoka, kunofanira kuenderana nemhepo inopisa turbine jenereta mushure mokunge vharuvhu yakavharwa yakabvumirwa kushanda nguva yekuisa, nguva inobvumirwa inowanzova 10 ~ 15min.Iko kuverenga uye kuita kwekuita kunoratidza kuti kana iyo steam turbine steam system iine bypass pombi, iyo inobvumirwa kushanda nguva yakareba.Nokudaro, kana kunonoka kwechiito chekugadzirisa kwakagadzirirwa maererano nenguva yakabvumirwa kumhanya mushure mokunge vheji huru ye turbine yakavharwa, 5 ~ 10min inokurudzirwa.Mushure mekuita, inoshandiswa kubvisa magnetic field.

Pamusoro pezvo, iwo maturbogenerator makuru ari kushanda anonyanya kushandisa reverse magetsi kugadzirisa kutanga chirongwa cherwendo loop.Parizvino, nguva yekuita inowanzova 1 ~ 2s.Kana iri kuchengetedzwa kwechirongwa-inodzorwa inverse simba, nekuda kwenguva pfupi yekushanda, iyo inoshanda inverse simba inogona kunge iri diki kwazvo munguva pfupi pfupi mushure meiyo main steam valve point yakavharwa nekuda kwe inertia ye turbine uye jenareta, saka. iyo yakagadziriswa kukosha kweiyo inverse simba haifanire kunge yakakura kupfuura 1% PN.

Kana jenareta iine reverse simba (yekunze simba mapoinzi kune jenareta, kureva, jenareta inova mamiriro emota), reverse simba rekugadzirisa oparesheni redunhu breaker rwendo.Matatu echikamu magetsi uye maviri echikamu masaini masaini anoda kuunganidzwa.Nekuda kwemhando dzakasiyana dzesimba rekutanga, majenareta akasiyana anogona kugadzirwa.Nekubatana kwezviwanikwa zvemvura uye turbine yemvura, hydro-jenareta inogona kugadzirwa.Nekuda kwekusiyana kwesimba rekuchengetedza uye kudonha kwemusoro, mahydrogenerators ane hunyanzvi hwakasiyana uye kumhanya anogona kuitwa.Nekushandiswa kwemarasha, oiri uye zvimwe zviwanikwa, uye neiyo boiler, turbine uye steam injini, iyo turbine jenareta inogona kugadzirwa, iyo inonyanya kumhanyisa mota (3000rpm).Pamusoro pezvo, kune marudzi ese emajenareta anoshandisa solar, mhepo, atomic, geothermal, tidal, bioenergy uye rimwe simba.Uye zvakare, nekuti iyo nheyo yekushanda yejenareta yakasiyana, inogona kukamurwa kuita DC jenareta, asynchronous jenareta uye synchronous jenareta.Iwo majenareta makuru anoshandiswa zvakanyanya majenareta anowirirana.

Dingbo ine mhando yemusango yemajenareta edhiziri:Volvo / Weichai / Shangcai/Ricardo/Perkins uye zvichingodaro, kana uchida pls taura nesu
