Amandla Ahlehla Emajeneretha Edizili

Uma ijeneretha inamandla ahlehlayo (amandla angaphandle akhomba kujeneretha, okungukuthi ijeneretha iba injini), amandla ahlehlayo avikela isinqamuli sesekethe sokukhubeka.I-voltage yezigaba ezintathu kanye namasignali amanje ezigaba ezimbili kudingeka aqoqwe.

Ngenxa yezinhlobo ezahlukene zamandla ayisisekelo, ama-generator ahlukene angenziwa.Ama-Hydrogenerator angenziwa ngamanzi nakuma-turbines.Ngenxa yomthamo wedamu elihlukile kanye nokwehla, ama-hydro-generator anomthamo ohlukile nesivinini angenziwa.Kusetshenziswa amalahle, uwoyela nezinye izinsiza, ngamaboilers nezinjini ze-turbo-steam, kungenziwa amajeneretha enjini yomusi, ikakhulukazi amamotho anesivinini esikhulu (3000rpm).Kukhona futhi amajeneretha asebenzisa ilanga, umoya, i-athomu, i-geothermal, i-tidal kanye ne-bioenergy.Ngaphezu kwalokho, ngenxa yezimiso ezihlukene zokusebenza zamajeneretha, zihlukaniswa zibe amajeneretha e-DC, ama-generator asynchronous kanye nama-generator synchronous.Amajeneretha amakhulu asetshenziswa kabanzi amajeneretha ahambisanayo.

Umkhiqizi we-generator Amandla ahlehlayo

Njengoba sonke sazi, isiqondiso samandla ejeneretha kufanele sigeleze sisuka lapho siya khona siye esiqondisweni sesistimu.Kodwa ngesizathu esithile, lapho i-turbine iphelelwa amandla futhi isishintshi se-generator outlet singahambi, isiqondiso samandla siyashintsha sisuka ohlelweni siye ku-generator, okungukuthi, i-generator iba injini esebenzayo.Kuleli qophelo ijeneretha idonsa amandla asebenzayo ohlelweni, olubizwa ngokuthi amandla aphambene.

01. Izingozi zokuphakelwa kwamandla okubuyela emuva.

Ukuvikelwa kwamandla e-generator okuphambene kubhekisela kulokho lapho i-turbine ilahlekelwa amandla ngenxa yokuvala kwevalve enkulu ngesizathu esithile, ijeneretha iphenduka ibe injini ukuze ishayele i-turbine ukuze ijikeleze.I-turbine blade ijikeleza ngesivinini esikhulu ngaphandle kwesitimu, okuzodala ukungqubuzana kokuqhuma, ikakhulukazi i-blade yesiteji sokugcina, engabangela ukushisa ngokweqile futhi kulimaze i-rotor blade.Ngakho-ke ukuvikela amandla ahlehlayo empeleni kuwukuvikela i-turbine ngaphandle kokusebenza.

02.Uhlelo lokuvikela amandla e-Generator.

Uhlelo lwe-generator ukuvikela amandla aphambene ikakhulukazi ukuvimbela ijeneretha ukuthi ivule ngokuzumayo iswishi ye-motor outlet, futhi wonke ama-valve amakhulu e-turbine awakwazi ukuvalwa ngaphansi komthwalo othile.Kulokhu, isethi ye-turbine generator ijwayele ukuhamba ngesivinini esiphezulu noma ngaphandle kokulawula.Ukuze ugweme lokhu, ngokuvikela okuthile okungekona okwesiyingi esifushane, iqala ngokuvala i-valve eyinhloko ye-turbine ngemva kokuthumela isignali yesenzo.Ngemuva kokuthi i-generator inverse power relay isetshenziswe, isignali yokuvala i-valve eyinhloko iyakhiwa futhi isango liyakhiwa.Ngemuva komkhawulo wesikhathi esifushane, uhlelo lokuvikela amandla aphambene luyakhiwa futhi ukusebenza kumiswe ngokuphelele.

03.Hlehlisa ukuvikelwa kwamandla kanye nohlelo lokuhlehlisa umehluko wokuvikela amandla.

Ukuhlehla ukuvikela amandla ukuvimbela ijeneretha ukusuka emandleni ahlehlayo ukuya enjini, eshayela ukuzungezisa kwe-turbine, okuholela ekulimaleni kwe-turbine.Phela, ngesaba ukuthi umhambisi oyinhloko uzosebenza nesistimu ngenxa yokuntuleka kwamandla! Ukuvikelwa kwamandla okuhlehla okuhleliwe kuklanyelwe ukuvimbela i-turbine ekugijimeni ngokweqile ngemva kokuba isethi yejeneretha inqanyulwe ngokuzumayo futhi i-valve eyinhloko ivalwe ngokuphelele, engakwazi kugwenywe ngokusebenzisa amandla ahlehlayo.Iphuzu elibalulekile ukuthi umhambisi oyinhloko unamandla kakhulu ukubangela iyunithi ukuthi igijime ngokweqile!

Ngakho-ke, uma sikhuluma ngokuqinile, ukuvikela amandla ahlehlayo kuyisivikelo se-relay ye-generator, kodwa ikakhulukazi ukuvikela i-turbine.Ukuvikelwa kwamandla okuhlehla kohlelo akusona isivikelo, kodwa inqubo yesenzo esethwe ukuze kuzuzwe uhambo lohlelo, okwaziwa nangokuthi uhambo lohlelo, oluvame ukusetshenziswa kumodi yokuvala shaqa.
