Taw Qhia Rau Txoj Cai Ntawm Diesel Generators

Tom qab lub ntsiab valve ntawm lub turbine raug kaw, daim phiaj sib txuas turbogenerator ua haujlwm raws li lub cev muaj zog synchronous, nqus lub zog nquag thiab rub lub turbine tig, yog li tsim lub zog reactive rau lub cev.Vim hais tias lub ntsiab valve ntawm lub chav turbine tau raug kaw, lub chav turbine tail hniav thiab seem seem ntawm chav sib txhuam, tsim tawg puas, overheating puas tom qab ua hauj lwm mus sij hawm ntev.Gas thiab dej turbines kuj tseem ua rau cov neeg tsiv teb tsaws chaw. Lub tshuab hluav taws xob rov qab lub zog tiv thaiv tsuas yog tiv thaiv lub turbine los ntawm kev puas tsuaj.

Kev teeb tsa ntawm chav turbine thim rov qab kev tiv thaiv hluav taws xob yog los txiav txim siab tiv thaiv kev ua haujlwm fais fab Pdz thiab kev ua haujlwm ncua T.

1, Lub zog ua haujlwm ntawm kev tiv thaiv hluav taws xob rov qab ntawm lub turbogenerator tuaj yeem xam raws li hauv qab no: Pdz = (krel * P1) / ηPdz- lub zog ua haujlwm ntawm kev tiv thaiv hluav taws xob rov qab krel- kev ntseeg tau coefficient, siv 0.8 P1- lub zog siv los ntawm lub turbine tswj lub synchronous ceev tom qab lub ntsiab valve raug kaw, Nws muaj feem xyuam rau cov qauv thiab lub peev xwm ntawm chav turbine.Nws kuj muaj feem xyuam rau cov qauv ntawm lub ntsiab chav dej ntawm lub tshuab hluav taws xob turbine (pipeline qauv thiab seb puas muaj cov kav dej bypass, thiab lwm yam).Raws li ib txwm muaj, lub zog ntsuas η ntawm 1.5 ~ 2% (qhov ua tau zoo thaum lub tshuab hluav taws xob tsav lub tshuab hluav taws xob tig mus) yog 0.98 ~ 0.99, yog li: PDZ∑ (1.2 ~ 1.6%) PN - lub zog ntsuas ntawm lub tshuab hluav taws xob.Qhov tseeb, Pdz = 1-1.5% PN yog qhov zoo dua.

2 、 Kev ua haujlwm qeeb .Qhov kev ncua sijhawm ntawm lub tshuab hluav taws xob tiv thaiv hluav taws xob yuav tsum tau teeb tsa raws li lub sijhawm tso cai khiav ntawm lub ntsiab valve kaw ntawm lub tshuab hluav taws xob turbine.Lub sijhawm tso cai yog feem ntau 10 ~ 15 feeb.Kev suav thiab kev xyaum ua haujlwm qhia tau hais tias thaum lub tshuab turbine muaj bypass yeeb nkab, lub sijhawm ua haujlwm tau ntev dua.Yog li ntawd, yog tias qhov kev tiv thaiv ncua sij hawm tau teem caij raws li lub sijhawm tso cai khiav tom qab lub ntsiab valve ntawm chav turbine raug kaw, 5 ~ 10 feeb tuaj yeem noj.Tom qab kev txiav txim, nws yog siv rau demagnetization.

Tsis tas li ntawd, feem ntau cov turbogenerators loj hauv kev ua haujlwm siv thim rov qab kev tiv thaiv hluav taws xob los pib qhov programmed mus ncig ua si.Hauv qhov no, lub sijhawm ua haujlwm feem ntau siv sijhawm 1 txog 2s.Rau programmed inverse zog tiv thaiv, vim lub sij hawm ua hauj lwm luv luv, qhov tseeb inverse hwj chim tej zaum yuav me me vim lub inertia ntawm lub chav turbine thiab generator nyob rau hauv ib tug luv luv lub sij hawm tom qab lub ntsiab valve raug kaw, yog li ntawd tus nqi ruaj khov ntawm lub zog inverse yuav tsum. tsis ntau tshaj 1% PN.

Generator Chaw tsim tshuaj paus kev taw qhia txoj cai

Thaum lub tshuab hluav taws xob muaj hluav taws xob rov qab (qhov hluav taws xob sab nraud taw qhia rau lub tshuab hluav taws xob, piv txwv li lub tshuab hluav taws xob dhau los ua lub cev muaj zog), lub zog rov qab tiv thaiv qhov kev txiav txim hluav taws xob los ntawm tripping.Peb theem voltage thiab ob theem tam sim no teeb liab yuav tsum tau sau.

Vim yog cov qauv sib txawv ntawm lub zog tseem ceeb, cov tshuab hluav taws xob sib txawv tuaj yeem ua tau.Hydrogenerators tuaj yeem tsim los ntawm dej thiab turbines.Vim muaj peev xwm sib txawv ntawm lub reservoir thiab poob, hydro-generators nrog lub peev xwm sib txawv thiab ceev tuaj yeem tsim.Siv cov thee, roj thiab lwm yam kev pab, nrog rau cov boilers thiab turbo-steam xyaw, chav turbine generators yuav ua tau, feem ntau high-ceev motors (3000rpm).Kuj tseem muaj cov tshuab hluav taws xob uas siv hnub ci, cua, atomic, geothermal, tidal thiab bioenergy.Tsis tas li ntawd, vim yog cov qauv kev ua haujlwm sib txawv ntawm cov tshuab hluav taws xob, lawv tau muab faib ua DC generators, asynchronous generators thiab synchronous generators.Cov generators loj siv dav yog synchronous generators.
