I-Generator Reverse Power Maintenance

Ukusetha ukubala kwe-steam turbine ukugcinwa kwamandla aphambene ukuqinisekisa amandla okusebenza kwe-Pdz kanye nokubambezeleka kwesenzo esingu-T kokulungiswa.

1. Amandla esenzo se-Pdz setha i-turbogenerator ephambene namandla esenzo sokulondoloza amandla angabalwa ngokuvumelana nefomula elandelayo: Pdz=(Krel*P1)/η Pdz- amandla okusebenza okuguquguqukayo okugcinwa kwamandla e-Krel- ukuthembeka kwe-coefficient, thatha u-0.8 P1- amandla asetshenzisiwe nge-turbine ukuze kugcinwe isivinini sokujikeleza okuvumelanayo ngemva kokuba i-valve eyinhloko ivaliwe, ubukhulu bala mandla buhlobene nesakhiwo namandla e-turbine, Ibuye ihlotshaniswe nesakhiwo sesistimu ye-steam eyinhloko ye-turbogenerator (isakhiwo sepayipi kanye noma ngabe kukhona ipayipi lokudlula, njll.).Ngokuvamile, amandla alinganiselwe angu-1.5~2% η- amandla ejeneretha lapho ijeneretha ihudula i-turbogenerator ukuze izungezise, ​​futhi 0.98~0.99, ngakho: Pdz≈ (1.2~1.6%) PN PN- amandla alinganiselwe we-generator .Empeleni, i-Pdz= ingaba ngu-1-1.5% PN.

2.Ukubambezeleka kwesenzo ijeneretha ukubambezeleka kwesenzo sokugcinwa kwamandla okuphambene, kufanele kuhambisane nejeneretha yeturbine yesitimu ngemva kokuba ivalvu eyinhloko ivaliwe ivunyelwe ukusebenzisa isikhathi sokusetha, isikhathi esivunyelwe ngokuvamile siyi-10~15min.Ukubala nokusebenza kubonisa ukuthi uma uhlelo lwesitimu lwe-steam turbine inepayipi lokudlula, isikhathi sokusebenza kufanele sibe side.Ngakho-ke, uma ukubambezeleka kwesenzo sokunakekela kusethwa ngokuya kwesikhathi esivunyelwe ukusebenza ngemva kokuvalwa kwevalvu ye-steam turbine, 5~10min kuyancomeka.Ngemuva kwesenzo, isetshenziselwa ukukhipha insimu kazibuthe.

Ukwengeza, ama-turbogenerator amakhulu asebenzayo ngokuvamile asebenzisa ukulungiswa kwamandla ahlehlayo ukuze aqale iluphu yohambo lohlelo.Okwamanje, isikhathi sesenzo ngokuvamile sithatha 1~2s.Ukugcinwa kwamandla aphambene nokulawulwa kohlelo, ngoba isikhathi sokusebenza sifushane, ngesikhathi esifushane kakhulu ngemuva kokuvalwa kwephuzu eliyinhloko le-valve yesitimu, ngenxa ye-inertia ye-turbine ne-generator, amandla aphambene angokoqobo angase abe mancane kakhulu, ngakho-ke inani eligxilile lamandla aphambene akufanele libe likhulu kuno-1% PN.

Isingeniso sesimiso

Uma ijeneretha inamandla ahlehlayo (amaphuzu wamandla angaphandle kujeneretha, okungukuthi, ijeneretha iba isimo semoto), umsebenzi wokulungisa amandla okubuyisela emuva uyahamba.Isidingo siqoqa i-voltage yezigaba ezintathu kanye nezimpawu zamanje zezigaba ezimbili.

Ngenxa yezinhlobo ezahlukene zamandla ayisisekelo, ama-generator ahlukene angenziwa.Ukusebenzisa imithombo yamanzi kanye nokubambisana kwe-turbine yamanzi, kungenziwa kube yi-generator ye-turbine yamanzi;Ngenxa yomehluko womthamo we-reservoir kanye nokwehla kwekhanda, ama-hydro-generator anamandla ahlukene kanye nesivinini angenziwa.Kusetshenziswa amalahle, uwoyela nezinye izinsiza kanye nokusebenzisana namaboilers nezinjini ze-turbo-steam, kungenziwa ama-turbo-generator, okungamamotho anesivinini esikhulu (3000rpm).Ngaphezu kwalokho, kukhona zonke izinhlobo zamajeneretha asebenzisa amandla elanga, amandla omoya, amandla e-athomu, amandla e-geothermal, amandla olwandle, amandla e-biological nokunye.Ngaphezu kwalokho, ngenxa yokuthi umgomo wokusebenza kwe-generator uhlukile futhi uhlukaniswe waba yi-dc generator, i-asynchronous generator kanye ne-synchronous generator.Ekusetshenzisweni okubanzi kwamajeneretha amakhulu kukhona amajeneretha angama-synchronous.

I-Guangxi Dingbo Power Equipment Manufacturing Co., Ltd. eyasungulwa ngo-2006, ingumkhiqizi wejeneretha kadizili eChina, ehlanganisa ukuklama, ukuhlinzeka, ukugunyazwa kanye nokugcinwa kwesethi yejeneretha yedizili.Umkhiqizo uhlanganisa i-Cummins, i-Perkins, Volvo , Yuchai, Shangchai, Deutz, Ricardo, MTU, Weichai njll. enebanga lamandla angu-20kw-3000kw, futhi babe yisikhungo sabo semboni ye-OEM nobuchwepheshe.
