Vim li cas thiaj xaiv pebPeb Qhov Zoo

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.

SVG raws li lub zog muaj zog reactive, siv cov khoom siv hluav taws xob ceev xws li DSP / IGBT, ua ke nrog cov kev tswj hwm kev tswj hwm, txhawm rau taug qab lub sijhawm hloov pauv hauv daim phiaj tam sim no, thiab nce PF tus nqi rau 0.99 hauv 15ms.
Kev siv dav dav ntawm lub peev xwm loj uas tsis yog-linear loads thiab impulse loads xws li cov khoom siv hluav taws xob hluav taws xob hauv kev sib kis thiab kev faib cov phiaj xwm thiab cov neeg siv kev lag luam tau coj teeb meem loj zog. SVG tuaj yeem txhim kho lub zog zoo ntawm qhov chaw sib txuas ntawm cov khoom thauj thiab cov phiaj xwm pej xeem, xws li kev txhim kho lub zog, kov yeej peb theem tsis txaus, tshem tawm qhov hluav taws xob flicker thiab qhov hluav taws xob hloov pauv, thiab txo qis kev sib haum xeeb.
SVG dynamic reactive fais fab nyiaj them nyiaj ntaus ntawv tsim los ntawm peb lub tuam txhab muaj qhov zoo hauv cov lus teb ceev, ruaj khov kab hluav taws xob, txo qhov kev poob qis, nce kev sib kis quab yuam, txhim kho kev hloov pauv hluav taws xob, txo kev sib haum xeeb, thiab txo qis hneev taw.Qhov kev txhim kho ntawm SVG vam khom ntawm peb lub tuam txhab muaj zog technical zog, siv tag nrho peb cov kev tshawb fawb, tsim, tsim, thiab kev xeem muaj peev xwm. Peb lub tuam txhab muaj kev sib raug zoo kev kawm thiab kev koom tes nrog cov kws tshawb fawb paub zoo thiab cov tuam txhab hluav taws xob hauv tsev thiab txawv teb chaws. Peb txaus siab ua haujlwm ua ke nrog peb cov neeg siv khoom los txhim kho lub zog zoo ntawm daim phiaj hluav taws xob nrog cov cuab yeej siv siab tshaj plaws thiab cov khoom zoo, thiab pab txhawb kev txuag hluav taws xob, txo kev noj, thiab kev nyab xeeb hauv kev tsim hluav taws xob, khoom siv, thiab kev noj haus.

Tau ntsib nrog cov teeb meem loj ntawm lub zog sib haum xeeb muaj kuab paug, AHF yog cov cuab yeej zoo tshaj plaws los txhim kho lub zog zoo. AHF yog cov cuab yeej tshwj xeeb tshiab rau kev tswj hwm kev sib haum xeeb tsim los siv cov cuab yeej hluav taws xob niaj hnub siv hluav taws xob thiab cov teeb liab ua cov cuab yeej siv hluav taws xob raws li kev ua haujlwm siab DSP. AHF yog sib npaug rau lub tshuab hluav taws xob tam sim no, uas taug qab cov khoom sib haum xeeb hauv cov khoom sib haum xeeb tam sim no thiab tsim cov kev sib haum xeeb nrog qhov sib npaug ntawm qhov sib npaug thiab qhov sib npaug. Cov kev qhia tam sim no ua haujlwm Circuit Court kuaj pom cov tam sim no hauv Circuit Court hauv lub sijhawm, hloov cov teeb liab analog tam sim no rau hauv cov teeb liab digital, thiab xa mus rau high-speed digital processor (DSP) rau kev ua cov teeb liab. Cov kev sib haum xeeb thiab qhov tseem ceeb tam sim no raug cais kom tau txais cov lus qhia tam sim no, tom qab ntawd xa mus rau qhov them nyiaj tam sim no hauv Circuit Court nyob rau hauv daim ntawv ntawm pulse width modulation (PWM) teeb liab los ntawm kev tswj xyuas tam sim no thiab tsav Circuit Court. Lub IGBT thiab IPM fais fab modules tau tsav los tsim cov nyiaj them tam sim no nrog tib lub amplitude thiab opposite polarity raws li cov kev sib haum xeeb tam sim no, uas yog txhaj rau hauv daim phiaj fais fab kom them los yog tshem tawm cov kev sib haum xeeb tam sim no, nquag tshem tawm lub zog sib haum xeeb, thiab ua tiav kev sib tw, nrawm. , thiab kev ua tiav ntawm lub zog sib haum xeeb.

IGES tuaj yeem them nyiaj rau qhov muag tsis pom kev hauv kev saib xyuas thiab kev tiv thaiv ntawm cov chaw nres tsheb hauv av uas twb muaj lawm, thiab yog qhov kev ceeb toom ntxov thiab kev tiv thaiv uas paub txog kev tswj hwm digital thiab ntse ntawm substation grounding networks. IGES tuaj yeem muab ntau lub ntsiab lus thiab ntau qhov kev soj ntsuam online hauv lub sijhawm tiag tiag thiab cov ntaub ntawv waveform, ua tib zoo saib xyuas cov kab ke hauv av kev nyab xeeb kev nyab xeeb, muaj kev ceeb toom ua haujlwm, thiab muaj peev xwm tiv thaiv ntau yam overvoltage thiab grounding kev nyab xeeb txaus ntshai nyob rau hauv lub thib ob system.
