MV SVC kugirango ikemure ibibazo bya Flickelharmonic na Dynamic Reaction Indishyi

SVC yacu ikubiyemo ubwoko butatu kugirango ihuze ibikenewe n'inganda zitandukanye: MCR, TSC, na TCR. Ubwoko bwa MCR SVC ifata ibyishimo bya DC kandi bikagabanya uburyo bwo gukora bwuzuye bwa magnetiki, ntibigabanya cyane imiterere yabyaye gusa, ariko kandi bifite imbaraga nke zo gutakaza imbaraga kandi byihuse. Muguhindura inguni ya thyristor muri sisitemu yo kwishima ya MCR, urugero rwuzuye rwuzuye rwa magnetiki rwibanze rwibanze rwa reaction ya magnetique irashobora guhinduka, bityo bigahindura imbaraga zububasha bwa reaction ziva mumashanyarazi.

Ubwoko bwa MCR SVC bufite ubwizerwe buhebuje, kubungabunga ubuntu, hamwe nubuzima bwa serivisi butari munsi yimyaka 20. Sisitemu zingenzi nkamashanyarazi ya gari ya moshi zikurura amashanyarazi zahawe umwanya wambere kugirango zemerwe; Birashoboka imikorere ihamye kandi yizewe muburyo ubwo aribwo bwose bukomeye bwa gride ikora (nko kugoreka imbaraga za voltage, kugoreka kwa amplitude, nibindi); Irashobora gukora muburyo butaziguye mumashanyarazi ayo ari yo yose (6-500kV), kandi biroroshye kuyashyiraho (bisa na transformateur zisanzwe) no gukuramo; Ubushobozi bwindishyi zingufu zirashobora guhinduka kuburyo budasubirwaho kugirango tugere ku ngaruka nziza.

ibicuruzwa birambuye

Umuvuduko mwinshi wa TSC dinamike reaction yingufu zigizwe na sisitemu yo kugenzura, sisitemu yo gukurura, sisitemu yo kugenzura thyristor, impinduramatwara ya pulse, capacitor, reaction, ishami ririnda, nibindi. Sisitemu yo kugenzura igaragaza imbaraga zidasanzwe za sisitemu yamashanyarazi mugihe nyacyo, ihita igena ishami rya capacitori igomba guhinduka, hanyuma ikagenzura itsinda rya thyristor valve ryishami rihuye kugirango rigere ku guhinduranya kwa capacitori. Ibikorwa byavuzwe haruguru byikora rwose, byemeza ko nta ngaruka, kwiyongera, cyangwa inzibacyuho mugihe uhindura ubushobozi.

Ubwoko bwa TCR ubwoko bwa SVC bugizwe ahanini nibice bibiri: TCR (reactor igenzurwa na thyristor) na FC (banki ya filter capacitor) byagezweho. Cyane cyane kubice bitatu bya AC arc itanura imitwaro, ihindagurika rya voltage na flicker byakozwe birashobora kugabanuka. Muri icyo gihe, ubwoko bwa TCR bwa SVC bufite imikorere yo gutandukanya icyiciro cyo gutandukanya, gishobora kuringaniza imizigo itaringaniye y itanura ryicyiciro cya gatatu cya arc arc hamwe nindi mizigo, kandi igahagarika ibice bikurikirana bikurikirana amashanyarazi kugeza byibuze.

Ibicuruzwa byiza

• Umuyoboro wa thyristor ukoresha uburyo bwo gukurura ifoto ya elegitoronike, hamwe na thyristor BOD ikingira, imbaraga zikomeye zo kurwanya kwivanga, nuburinzi bwizewe;

• Imiterere yumubiri wa valve ifata igishushanyo gitambitse, hamwe nibikoresho byoroheje, imikorere yizewe, hamwe nakazi gake ko kubungabunga;

• Itumanaho rya fibre optique rikoreshwa hagati ya sisitemu yo kugenzura nigice cyingufu, bikavamo ibimenyetso bihamye;

• Igikoresho cya thyristor kigenzurwa gifite imirimo yo gukingira nko gutakaza amashanyarazi ahwanye, gutakaza impiswi, kutagira impiswi, no gusenyuka kwa thyristor.
