Yuav ua li cas tswj qhov system ntawm diesel generator teeb ua haujlwm

Tam sim no, nrog kev nce ntxiv ntawm kev lag luam kev lag luam, kev siv hluav taws xob niaj hnub ntawm cov chaw zov me nyuam kuj tseem qhia txog kev sib koom ua ke. Thaum muaj hluav taws xob hluav taws xob tshwm sim, ib lub tshuab hluav taws xob ib leeg tsis tuaj yeem ua tau raws li qhov xav tau ntawm lub zog thaub qab ntawm cov ntaub ntawv chaw. Yog li ntawd, ntau chav nyob feem ntau yuav tsum tau ua haujlwm nyob rau hauv parallel. Yog li cas qhov kev tswj hwm ntawm lub tshuab hluav taws xob diesel teeb ua haujlwm li cas?

Cia wb mus saib ua ke.

1, txhawm rau ua kom muaj kev ruaj ntseg ntawm kev ua haujlwm sib luag ntawm cov tshuab hluav taws xob diesel, kev tswj xyuas feem ntau yog siv, uas txhais tau tias tau txais kev ruaj khov thiab qhov hluav taws xob los ntawm P / f droop tswj thiab Q / V droop tswj nyias. Txoj kev tswj hwm no tswj cov khoom siv hluav taws xob thiab cov hluav taws xob tawm ntawm txhua chav sib cais, tsis tas yuav tsum muaj kev sib raug zoo ntawm kev sib txuas lus ntawm cov units, ua kom tiav kev sib npaug ntawm cov chav nyob, kom ntseeg tau tias qhov kev xav tau ntawm cov khoom sib npaug thiab qhov sib npaug ntawm qhov sib npaug ntawm lub tshuab hluav taws xob diesel.

2, Cov kev tswj ceev (yuav ua haujlwm zaus) yog raws li qhov ntsuas fais fab fN ntawm lub tshuab hluav taws xob synchronous. Thaum lub zog ua haujlwm ntawm cov dej ntws qis nce mus rau Pred, qhov tso zis zaus ntawm lub tshuab hluav taws xob synchronous poob rau tus nqi ruaj khov tshiab ntawm fref. Txoj kab nqes ntawm ntu AB yog qhov hloov kho zoo li qub coefficient mp ntawm lub tshuab hluav taws xob synchronous, Δ F=fref fN, Δ P=PN Liab. Thaum lub tshuab hluav taws xob diesel ua haujlwm ua ke, txhua lub tshuab hluav taws xob dynamically kho nws cov zaus thiab lub zog kom txog rau thaum tag nrho cov kev xav tau ntawm kev thauj khoom.

3, Kev tswj hluav taws xob (reactive voltage control) system yog tib yam, thiab txoj kab nqes ntawm CD ntu yog hu ua reactive voltage droop control coefficient nq ntawm lub tshuab hluav taws xob synchronous, uas qhia txog kev sib raug zoo ntawm reactive zog increment ntawm lub generator teeb thiab lub davhlau ya nyob twg voltage deviation Δ U=Uref UN, Δ Q=QN Qred. Nws tuaj yeem pom los ntawm kev tswj hwm daim duab duab ntawm synchronous generator excitation zog chav tsev uas qhov siv hluav taws xob tau txais los ntawm kev suav ntawm kev ntsuas kev sib txuas thiab qhov sib txawv hloov kho qhov txuas, thiab tom qab ntawd muab piv nrog lub tshuab hluav taws xob qhov hluav taws xob hluav taws xob (qhov twg qhov voltage regulator yog PI ua), yog li ntawd lub tshuab hluav taws xob davhlau ya nyob twg voltage ib txwm taug qab qhov voltage hais kom sai.
