MV SVC daws teeb meem Flickelharmonic thiab Dynamic Reactive Compensation

Peb SVC suav nrog peb hom kom tau raws li cov kev xav tau ntawm kev lag luam thiab chaw sib txawv: MCR, TSC, thiab TCR. MCR hom SVC txais nws tus kheej ua ke DC excitation thiab txwv kev sib nqus saturation ua hauj lwm hom, uas tsis tsuas yog txo cov generated harmonics, tab sis kuj muaj tsawg active zog poob thiab ceev teb ceev. Los ntawm kev hloov lub triggering lub kaum sab xis ntawm lub thyristor nyob rau hauv lub MCR excitation system, lub saturation degree ntawm cov hlau nplaum flux nyob rau hauv cov tub ntxhais ntawm lub magnetic tswj reactor yuav hloov, yog li hloov lub reactive hwj chim muaj peev xwm tso zis ntawm lub magnetic tswj reactor.

MCR hom SVC muaj kev ntseeg siab heev, tsis muaj kev saib xyuas, thiab kev pabcuam lub neej tsis pub tsawg tshaj 20 xyoo. Cov tshuab tseem ceeb xws li hluav taws xob railway traction fais fab mov network tau muab qhov tseem ceeb rau kev saws me nyuam; Muaj peev xwm ua haujlwm ruaj khov thiab txhim khu kev qha hauv txhua qhov chaw ua haujlwm hnyav hluav taws xob (xws li qhov hluav taws xob waveform distortion, loj amplitude fluctuations, thiab lwm yam); Nws tuaj yeem ua haujlwm ncaj qha hauv txhua qhov hluav taws xob hluav taws xob hluav taws xob (6-500kV), thiab yooj yim rau nruab (zoo ib yam li cov tshuab hloov hluav taws xob zoo tib yam) thiab debug; Lub reactive fais fab nyiaj them peev xwm tuaj yeem hloov kho infinitely kom ua tiav cov txiaj ntsig zoo tshaj plaws.

cov khoom paub meej

Lub high-voltage TSC dynamic reactive zog them nyiaj ntaus ntawv muaj xws li ib tug tswj system, triggering system, thyristor xyuas system, mem tes transformer, capacitor, reactor, tiv thaiv chav tsev, thiab lwm yam. Lub kaw lus tswj xyuas lub reactive zog ntawm lub hwj chim system nyob rau hauv lub sij hawm, txiav txim siab lub capacitor ceg uas yuav tsum tau hloov, thiab ces tswj lub ceg ntawm thyristor hloov mus rau lub valve. pawg capacitor. Cov txheej txheem saum toj no yog ua tiav tag nrho, ua kom tsis muaj kev cuam tshuam, nce siab, lossis kev hloov pauv thaum hloov cov capacitors.

TCR hom SVC ntaus ntawv feem ntau muaj ob ntu: TCR (thyristor tswj reactor) thiab FC (filter capacitor bank).The FC circuits combines filtering function and can provide fixed capacitive reactive power, hos TCR circuit change the inductive reactive power output of the phase controlled reactor by thyristor control.Due to the speed of 1 dynamic reactive reactive hwj chim. milliseconds, real-time dynamic them nyiaj ntawm reactive zog yuav ua tau tiav. Tshwj xeeb tshaj yog rau peb-theem AC arc furnace loads, qhov voltage fluctuations thiab flicker generated yuav txo tau. Nyob rau tib lub sijhawm, TCR hom SVC muaj cov txheej txheem kev sib cais, uas tuaj yeem sib npaug ntawm qhov tsis sib npaug ntawm peb-theem AC arc rauv thiab lwm yam khoom thauj, thiab txo qis qhov tsis zoo ntawm daim phiaj hluav taws xob mus rau qhov tsawg kawg nkaus.
