Isingeniso Somgomo Wamajeneretha Edizili

Ngemuva kokuthi i-valve eyinhloko ye-turbine ivaliwe, i-turbogenerator exhunywe kugridi isebenza njengenjini ehambisanayo, idonsa amandla asebenzayo futhi ihudule i-turbine ukuze ijikeleze, ngaleyo ndlela ikhiqize amandla asebenzayo ohlelo.Ngenxa yokuthi i-valve eyinhloko ye-steam turbine ivaliwe, i-steam turbine tail blade kanye nensalela yokungqubuzana kwesitimu, okwenza umonakalo wokuqhuma, umonakalo oshise ngokweqile ngemva kokusebenza isikhathi eside.Izinjini zegesi namanzi nazo zilimaza kakhulu isihambisi esikhulu. Ijeneretha ukuhlehla ukuvikela amandla ikakhulukazi kuvikela i-turbine emonakalweni.

Ukulungiselelwa kokuvikelwa kwamandla okuphambene ne-steam turbine ukucacisa amandla esenzo sokuvikela i-Pdz kanye nokubambezeleka kwesenzo esingu-T.

1, Amandla okusebenza okuvikela amandla ahlehlayo e-turbogenerator angabalwa kanje :Pdz =(krel * P1)/ηPdz- amandla okusebenza we-reverse amandla ukuvikela i-krel- ukuthembeka coefficient, thatha 0.8 P1- amandla adliwe i-turbine yokugcina isivinini sokuvumelanisa ngemva kokuba i-valve eyinhloko ivaliwe, Ihlobene nesakhiwo namandla we-steam turbine.Ibuye ihlotshaniswe nesakhiwo sesistimu ye-steam eyinhloko ye-generator turbine (isakhiwo sepayipi nokuthi ngabe kukhona amapayipi okudlula, njll.).Ngaphansi kwezimo ezivamile, amandla alinganiselwe η ka-1.5 ~ 2%(ukusebenza kahle lapho ijeneretha ishayela ijeneretha yomshini ukuze izungezise) ngu-0.98~0.99, ngakho :PDZ∑(1.2 ~ 1.6%) PN - amandla alinganiselwe wejeneretha.Eqinisweni, i-Pdz = 1-1.5% PN ingcono.

2, Ukubambezeleka kwesenzo .Ukubambezeleka kwesenzo sokuvikela amandla aphambene nejeneretha kufanele kusethwe ngokuya kwesikhathi esivumelekile sokusebenza sokuvala kwevalvu eyinhloko yejeneretha ye-turbine.Isikhathi esivumelekile ngokuvamile siyimizuzu eyi-10 ~ 15.Ukubala nokusebenza kubonisa ukuthi uma isistimu ye-steam turbine inepayipi yokudlula, isikhathi esivumelekile sokusebenza siba side.Ngakho-ke, uma ukubambezeleka kwesenzo sokuvikela kusethwa ngokuya kwesikhathi esivunyelwe sokusebenza ngemuva kokuvalwa kwevalvu eyinhloko ye-steam turbine, imizuzu emi-5 ~ 10 ingathathwa.Ngemva kwesenzo, isetshenziswa demagnetization.

Ngaphezu kwalokho, ama-turbogenerator amaningi amakhulu asebenzayo asebenzisa ukuvikelwa kwamandla ahlehlayo ukuze aqalise amasekhethi ohambo ahleliwe.Kuleli qophelo, isikhathi sesenzo ngokuvamile sithatha amasekhondi angu-1 ukuya kwangu-2.Ngokuvikela amandla aphambene nohlelo, ngenxa yesikhathi esifushane sokusebenza, amandla wangempela aphambene angase abe mancane ngenxa ye-inertia ye-steam turbine kanye nejeneretha ngesikhathi esifushane ngemva kokuvalwa kwe-valve eyinhloko, ngakho-ke inani eligxilile lamandla aphambene kufanele kungabi ngaphezu kuka-1%PN.

Umkhiqizi we-generator isingeniso isimiso

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.
