SVC yathu imaphatikizapo mitundu itatu kuti ikwaniritse zosowa zamafakitale ndi masamba osiyanasiyana: MCR, TSC, ndi TCR. Mtundu wa MCR SVC umatenga kudzikonda kophatikizana ndi DC ndikuchepetsa magwiridwe antchito a maginito, omwe samangochepetsa kwambiri ma harmonics opangidwa, komanso amakhala ndi kutayika kwamphamvu kwamphamvu komanso kuthamanga kwachangu. Ndi kusintha zinayambitsa mbali ya thyristor mu dongosolo MCR malemeredwe, machulukitsidwe digiri ya maginito flux pakatikati pa maginito ulamuliro riyakitala akhoza kusinthidwa, potero kusintha zotakasika mphamvu linanena bungwe la maginito ulamuliro riyakitala.

Mtundu wa MCR SVC umakhala wodalirika kwambiri, wopanda kukonza, komanso moyo wautumiki wazaka zosachepera 20. Machitidwe ofunikira monga magetsi oyendera njanji yamagetsi apatsidwa patsogolo kuti atengedwe; Kutha kugwira ntchito yokhazikika komanso yodalirika m'malo aliwonse owopsa a gridi yamagetsi (monga kupotoza kwa ma waveform, kusinthasintha kwakukulu kwa matalikidwe, etc.); Itha kugwira ntchito mwachindunji mu gridi yamagetsi aliwonse (6-500kV), ndipo ndiyosavuta kuyiyika (yofanana ndi ma transformer wamba) ndikuwongolera; Mphamvu yolipirira mphamvu yokhazikika imatha kusinthidwa mopanda malire kuti ikwaniritse chipukuta misozi.

    The mkulu-voteji TSC zotakasika zotakasika mphamvu chipukuta misozi chipangizo tichipeza dongosolo kulamulira, kuyambitsa dongosolo, thyristor polojekiti dongosolo, zimachitika thiransifoma, capacitor, riyakitala, chitetezo unit, etc. Dongosolo kulamulira detects mphamvu zotakasika za dongosolo mphamvu mu nthawi yeniyeni, basi amatsimikiza ndi capacitor nthambi kuti ayenera kusintha, ndiyeno amazilamulira valavu gulu la thyristor kusinthana ndi gulu la capator kusintha. gulu. Njira yomwe ili pamwambayi imakhala yokhazikika, kuonetsetsa kuti palibe chokhudza, mawotchi, kapena kusintha pamene mukusintha ma capacitor.
    The TCR mtundu SVC chipangizo makamaka tichipeza mbali ziwiri: TCR (thyristor ankalamulira riyakitala) ndi FC (sefa capacitor banki) FC dera amaphatikiza kusefa ntchito ndipo angapereke chokhazikika capacitive zotakataka mphamvu, pamene TCR amasintha inductive zotakasika mphamvu linanena bungwe gawo ankalamulira riyakitala kudzera thyristor control. zenizeni zenizeni zolipirira mphamvu zotakataka zitha kukwaniritsidwa. Makamaka pazigawo zitatu za ng'anjo ya AC arc, kusinthasintha kwamagetsi ndi kuphulika komwe kumapangidwa kumatha kuchepetsedwa. Pa nthawi yomweyo, TCR mtundu SVC ali gawo kupatukana lamulo ntchito, amene angathe kulinganiza katundu wosalinganizika wa magawo atatu AC ng'anjo arc ndi katundu wina, ndi kupondereza zoipa zinayendera gawo la gululi mphamvu kuti osachepera.
