Foreword: SVG (Static Var Generator), uas yog, high-voltage static var generator, tseem hu ua advanced static var compensator ASVC (Advanced Static Var Compensator) lossis static compensator STATCOM (Static Compensator), SVG (static compensator) thiab Peb. -phase high-power voltage inverter yog lub hauv paus, thiab nws cov zis voltage txuas nrog lub kaw lus los ntawm lub reactor, thiab khaws tib zaus thiab theem raws li qhov system sab voltage, thiab cov zis hluav taws xob txiav txim siab los ntawm kev kho cov kev sib raug zoo ntawm cov zis. voltage amplitude thiab qhov system voltage amplitude Qhov xwm thiab muaj peev xwm ntawm , thaum nws amplitude yog ntau tshaj qhov voltage amplitude ntawm lub system sab, nws yuav output capacitive reactive hwj chim, thiab thaum nws yog me dua li ntawd, nws yuav output inductive reactive zog.Nws yog hais txog cov cuab yeej rau dynamic reactive zog them los ntawm tus kheej-commutated hwj chim semiconductor choj converters.
Yog li dab tsi yog qhov kev thov ntawm SVG (static compensator)?
Ua ntej ntawm tag nrho cov, feem ntau siv SVG (static compensator) feem ntau yog siv nyob rau hauv lub ywj siab hwj chim daim phiaj system ntawm industrial cov neeg siv.Vim hais tias cov tuam haujlwm tseem ceeb hauv lub tebchaws, xws li lub tuam tsev muab hluav taws xob, yuav tswj xyuas lub zog thiab lub zog zoo ntawm cov neeg siv khoom lag luam.Muaj ntau yam kev txwv thiab kev txwv.Qhov ntawd txhais tau tias tshwj xeeb tshaj yog rau cov neeg siv khoom lag luam.Kev siv hluav taws xob ntau heev.Cov neeg siv yuav tsum siv SVG (Static Compensator) rau hauv-situ reactive zog them.Ntawm qhov tod tes, nws tuaj yeem txo nws tus kheej lub zog siv thiab ua tiav lub hom phiaj ntawm kev txuag hluav taws xob thiab txo qis emission, ntawm qhov tod tes.Muaj peev xwm ncav cuag cov khoom siv hluav taws xob rau kev lag luam.muab.Cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob zoo.
SVG (static compensator) yog qhov zoo tshaj plaws ntawm kev daws teeb meem tshwm sim los ntawm lub zog muaj zog, qhov sib txawv ntawm qhov hluav taws xob, qhov hluav taws xob hloov pauv thiab flicker.Yog li SVG (static compensator) tuaj yeem daws tau zoo kawg nkaus.Reactive zog them tus cwj pwm ntawm cua fais fab nroj tsuag.Tshwj xeeb tshaj yog nrog rau lwm yam khoom siv hluav taws xob xws li capacitors thiab reactors.Nrog kev siv.Nws tuaj yeem ua rau tus nqi ntawm kev sib koom ua ke reactive zog them nyiaj qis dua.Nyob rau tib lub sijhawm, vim qhov me me ntawm SVG (Static Compensator), nws muaj qhov ua tau zoo.Tsis muaj kev xav tau ntawm tib neeg kev saib xyuas, uas tseem tso cai rau cov cua ua liaj ua teb tsim txhua qhov chaw.Kev tsim kho ib txhij ntawm SVG (Static Compensator).
Rau cov khoom sib haum xeeb uas ua rau muaj cov ntsiab lus loj thiab kev txiav txim siab siab, piv txwv li.Reactive shocks feem ntau tshwm sim nyob rau hauv industrial hluav taws xob systems.Qhov tshwm sim Gaussian txoj kab nqes thiab sab theem yuav yog daim phiaj hluav taws xob.tsim distorted waveforms.Txij li thaum SVG (static compensator) nws tus kheej tsis yog qhov chaw ntawm kev sib haum xeeb.tib lub sijhawm.Nws muaj lub luag haujlwm ntawm kev them nyiaj rov ua haujlwm lub zog thiab tshem tawm cov khoom sib xyaw ua ke.
Nyob rau tib lub sijhawm, SVG (static compensator) kuj tsim nyog rau cov chaw uas cov khoom siv hluav taws xob yuav ua rau peb theem tsis sib npaug.Cov kab hluav taws xob tsis sib npaug ntawm peb-theem yuav tsim kom muaj kev sib haum xeeb ntau dua thiab cov kab tsis zoo sib xws.Ua kom qhov voltage distortion nyuaj.Yuav ua rau voltage hloov thiab flicker.SVG (Static Compensator).Nws muaj cov lus teb ceev heev.Cov lus teb yog tsawg dua 5ms, thiab nws tsis tuaj yeem muab cov kab hluav taws xob ruaj khov xws li cov khoom siv hluav taws xob.thiab reactive tam sim no.Nyob rau tib lub sijhawm, nws tseem tuaj yeem tshem tawm qhov tsis txaus ntawm peb-theem los ntawm kev siv nws tus kheej cov khoom them nyiaj ua haujlwm.Txhim kho kev siv cov cuab yeej xws li traction transformers, thiab tib lub sij hawm txwv tsis tshua muaj zaus oscillations hauv lub system.
SVG (static compensator) txais ntau yam los yog PWM thev naus laus zis los txo cov ntsiab lus ntawm kev sib haum xeeb hauv cov nyiaj tam sim no, thiab nws cov ntim thiab cov nqi tsawg dua li cov khoom siv ib txwm siv, cov khoom siv hluav taws xob, thiab cov thyristor-tswj reactors TCR.Sawv cev rau cov tsoos SVC thiab hais txog.SVG static compensator yog qhov kev txhim kho yav tom ntej.
