Dab tsi yog qhov cuam tshuam ntawm Excitation Poob rau Generator

Thaum lub sij hawm ib txwm ua hauj lwm ntawm lub tshuab hluav taws xob, lub excitation dheev ploj tag nrho los yog ib feem, uas yog hu ua poob ntawm excitation ntawm lub tshuab hluav taws xob.

Ntawm cov khoom ntawm lub tshuab hluav taws xob diesel, lub tshuab hluav taws xob tseem ceeb heev.Tom qab siv lub tshuab hluav taws xob diesel ntev ntev, lub tshuab hluav taws xob tuaj yeem poob excitation.Qhov xwm txheej no yog qhov qub.Tab sis qhov xwm txheej no yuav cuam tshuam rau qhov system. Dab tsi yog qhov cuam tshuam ntawm excitation loass rau lub tshuab hluav taws xob?

1.Low-excitation thiab poob-of-excitation generators absorb reactive zog los ntawm lub system, ua rau lub voltage ntawm lub hwj chim system poob.Yog hais tias lub reactive zog cia nyob rau hauv lub hwj chim system yog tsis txaus, qhov voltage ntawm ib co ntsiab lus nyob rau hauv lub hwj chim system yuav qis dua Tus nqi tso cai yuav ua rau kom ruaj khov kev khiav hauj lwm ntawm lub load thiab txhua lub hwj chim qhov chaw, thiab txawm ua rau lub voltage ntawm lub hwj chim system. vau.

2.Thaum lub tshuab hluav taws xob poob nws qhov kev zoo siab, vim qhov poob qis, lwm lub tshuab hluav taws xob hauv lub tshuab hluav taws xob yuav ua rau lawv cov hluav taws xob reactive tso tawm raws li qhov kev txiav txim ntawm qhov kev hloov kho tsis siv neeg ntawm cov khoom excitation, yog li ua rau qee qhov cov tshuab hluav taws xob , transformers los yog kab rau overcurrent, Nws backup tiv thaiv tej zaum yuav malfunction vim overcurrent, uas yuav nthuav lub Scope ntawm kev huam yuaj.

3.Tom qab lub tshuab hluav taws xob poob nws qhov kev sib nqus, vim lub viav vias ntawm lub tshuab hluav taws xob lub zog ua haujlwm thiab qhov poob ntawm qhov system voltage, nws yuav ua rau cov khoom siv hluav taws xob nyob ib puag ncig thiab lub kaw lus, lossis ntawm ntau qhov chaw ntawm lub zog hluav taws xob, poob. synchronization, ua rau lub kaw lus poob synchronization.Oscillation tshwm sim.

4.Qhov ntau dua qhov ntsuas lub peev xwm ntawm lub tshuab hluav taws xob, qhov ntau dua qhov reactive zog tsis txaus los ntawm qhov tsis tshua muaj excitation thiab poob ntawm excitation, thiab lub peev xwm ntawm lub tshuab hluav taws xob me me, lub peev xwm me me los them rau qhov reactive zog tsis txaus.Yog li ntawd, qhov ntau dua qhov piv ntawm ib lub tshuab hluav taws xob muaj peev xwm rau tag nrho lub peev xwm ntawm lub zog hluav taws xob, qhov loj dua qhov cuam tshuam tsis zoo rau lub zog hluav taws xob.

Dab tsi yog vim li cas rau qhov poob ntawm excitation ntawm lub tshuab hluav taws xob?

(1) Lub cim tom qab lub tshuab hluav taws xob poob nws qhov kev zoo siab: lub stator tam sim no thiab lub zog nquag ntawm lub tshuab hluav taws xob tau nce sai sai tom qab kev poob qis, thiab qhov sib piv nce thiab pib viav vias.

(2) Lub tshuab hluav taws xob tseem tuaj yeem xa qee qhov ntawm lub zog ua haujlwm tom qab tsis muaj kev zoo siab, thiab khaws cov kev taw qhia ntawm lub zog hluav taws xob xa tawm, tab sis tus taw tes ntawm lub ntsuas hluav taws xob ua ntu zus.

(3) Raws li tus stator tam sim no nce, nws lub ammeter pointer kuj ua ntu zus.

(4) Los ntawm lub zog reactive xa mus rau lub zog absorbed reactive, tus pointer kuj ua ntu zus.Tus nqi ntawm reactive zog absorbed yog kwv yees li proportional rau tus nqi ntawm reactive zog ua ntej poob ntawm excitation.

(5) Lub rotor Circuit Court induces alternating tam sim no thiab alternating magnetomotive quab yuam nrog plam zaus, yog li tus pointer ntawm lub rotor voltmeter kuj ncua sij hawm viav vias.

(6) Lub pointer ntawm lub rotor ammeter kuj oscillates ib ntus, thiab tus nqi tam sim no yog me dua li ua ntej qhov poob ntawm excitation.

(7) Thaum lub rotor Circuit Court qhib, ib qho eddy tam sim no yog induced nyob rau saum npoo ntawm lub rotor lub cev los ua ib tug rotating magnetic teb, uas kuj generates ib tug npaum li cas ntawm asynchronous zog.

Yuav ua li cas daws qhov teeb meem ntawm excitation poob ntawm lub tshuab hluav taws xob?

(1) Tom qab tsis muaj kev tiv thaiv excitation yog qhib qhib, lub excitation hom yog cia li hloov, thiab lub active load txo yog invalid thiab ua nyob rau hauv lub mus txawv tebchaws, nws yuav tsum tau ua raws li kev huam yuaj;

(2) Yog hais tias lub de-excitation hloov yog tripped los ntawm kev ua yuam kev, lub de-excitation hloov yuav tsum tau muab rov qab tam sim ntawd.Yog tias qhov rov qab kaw tsis ua tiav, lub tshuab hluav taws xob yuav raug tshem tawm thiab nres tam sim;

(3) Yog hais tias qhov poob ntawm excitation yog vim tsis ua hauj lwm ntawm lub excitation regulator AVR, tam sim ntawd hloov lub AVR los ntawm lub chaw ua hauj lwm channel mus rau lub standby channel, thiab hloov mus rau phau ntawv ua hauj lwm yog hais tias lub automatic hom tsis ua hauj lwm;

(4) Tom qab lub tshuab hluav taws xob poob kev zoo siab thiab lub tshuab hluav taws xob tsis mus, cov khoom siv hluav taws xob yuav tsum raug txo mus rau 120MW hauv 1.5min, thiab lub sijhawm tso cai khiav tom qab poob ntawm cov hlau nplaum yog 15min;

(5) Yog hais tias qhov poob ntawm excitation ua rau lub tshuab hluav taws xob oscillate, lub tshuab hluav taws xob yuav tsum tau txiav thiab kaw tam sim ntawd, thiab tom qab ntawd rov qab txuas rau kab sib chaws tom qab qhov excitation rov qab los.

Thaum lub tshuab hluav taws xob tshwm sim poob ntawm qhov excitation, peb yuav tsum paub qhov laj thawj thiab daws qhov teeb meem hauv lub sijhawm, kom tsis txhob cuam tshuam rau lub tshuab hluav taws xob.Dingbo Fais fab tsis tsuas yog muab kev txhawb nqa, tab sis kuj tsim diesel generator teeb , yog tias koj muaj kev npaj yuav, txais tos hu rau peb los ntawm email dingbo@dieselgeneratortech.com.
