I-HYSVGC series hybrid static var dynamic compensation device

Incazelo emfushane:

Idivayisi yesinxephezelo samandla asebenzayo aguqukayo e-low-voltage asebenzayo asebenzayo ifakwe kusistimu yokusabalalisa amandla kagesi aphansi ukuze kuthuthukiswe ikhwalithi kagesi wokusatshalaliswa kwamandla kagesi aphansi, kuthuthukiswe izinga lokusebenza nezinga lokuphatha lesinxephezelo samandla asebenzayo, kanye nokunikeza kangcono amakhasimende amandla.Kumandla asebenzayo aphansi we-low-voltage azenzakalelayo Idivayisi yesinxephezelo samandla asebenzayo asebenzayo ayingxubevange ephansi ene-voltage ephansi ethuthukiswayo futhi yanwetshwa ngesisekelo sedivayisi yesinxephezelo.

Ukwakhiwa kanye nomgomo wokusebenza we-HYSVGC
akha:
Ukwakheka kwesistimu ye-HYSVGC = isilawuli (ICMS) + imojula ye-SVG + jikelele ye-LC ICMS yokulawula edidiyelwe kanye nohlelo lokuqapha ukuze usethe imodi yokusebenza nemingcele ehlobene ye-LC ne-SVG, ukuboniswa kwesikhathi sangempela solwazi lwamandla, idatha ngaphambi nangemva kwesinxephezelo, umdwebo we-waveform, ukulawula nokuqapha isimo sokusebenza se-SVGLC Amachweba amadala ayishumi nesishiyagalombili, ukugcwaliseka okuguquguqukayo kwezinhlobo ezahlukene zenhlanganisela ye-SVG+LC Imojula ye-SVG iphendula ngokushesha ekushintsheni kwamandla asebenzayo esistimu, isinxephezelo samandla esisebenzayo sesinxephezelo esingaphezulu kwe-LC noma isinxephezelo esingaphansi ku-0.99 ukuze kuzuzwe ukushintsha okungenasinyathelo, isinxephezelo. amandla aguqukayo aguqukayo ajwayelekile i-LC Buyekeza amandla asebenzayo azinzile kakhulu futhi angavamile ukushintsha emthwalweni
umgomo wokusebenza:
Ukungaqhubeki okubangelwa ukushintsha kwephakethe le-TSC kuxazululwa ngokuphuma okuqhubekayo kwamandla asebenzayo wemojula ye-SVG, ukuze kuzuzwe umphumela wesinxephezelo esiqhubekayo esiguqukayo.

Imingcele Yezobuchwepheshe

isikhathi sokuphendula esisheshayo

Qaphela: Ijika elibomvu ijika lamanje elisebenzayo, futhi ijika elibomvu iwumphumela wamanje wesinxephezelo se-SVG.Ukusabela okusheshayo kufinyelelwa yimojula ye-SVG.Isikhathi sokuphendula esisheshayo se-SVG <50us, isikhathi sokuphendula esigcwele <<15 ms="">
I-SVG ku-HYSVGC ibonisa izinzuzo zokushintshwa kwamandla kagesi.Ku-SVC yendabuko, i-thyristor iwumsebenzi wokushintsha ngokushesha kuphela, ongakwazi ukubonisa inani "lokushintsha okusheshayo kwe-high-frequency" (imvamisa engaphezu kuka-100ms uma ushintsha, kuyilapho i-IGBT ku-SVG ingumzuzwana ongu-1) izikhathi zokushintsha iwashi zingadlula u-15000. izikhathi)
isicelo nezimo
Ngokuhlanganisa noma iyiphi ingxenye yamandla (imojula ye-SVG noma i-LC) kuhlelo lwe-HYSVGC,
Ukulungiswa kokusebenza kohlelo lwe-HYSVGC kungenziwa: uhla lwesinxephezelo lwe-HYSVGC lusuka ku- -1 kuya ku-1;
Thatha umthamo wesinxephezelo esingu-300kvar njengesibonelo:

umphumela wesinxephezelo
100~200ms:
Lapho amandla asebenzayo omthwalo ekhuphuka ngokuzumayo, i-LC ayinaso isikhathi sokuthatha isinyathelo, futhi i-SVG izophendula ngesikhathi sangempela ukunxephezela amandla asebenzayo wesistimu;
200~500ms:
I-LC iphendula isinxephezelo sokufaka, ngalesi sikhathi i-SVG izonciphisa umthamo wesinxephezelo ngesikhathi sangempela;
900~1000ms:
Lapho amandla asebenzayo omthwalo ehla ngokuzumayo, i-LC ayinaso isikhathi sokunqamula i-capacitor yokufaka, futhi i-SVG izothumela isinxephezelo esibuyisela emuva amandla asebenzayo ngesikhathi sangempela ukuze kunxeshezelwe umthamo omningi we-LC;
1000ms~:
I-LC isusa umthamo wesinxephezelo owedlulele, futhi ngalesi sikhathi, i-SVG izolandelela izinguquko zamandla asebenzayo esistimu ngesikhathi sangempela futhi isuse amandla asebenzayo asele ohlelweni.

Okwedlule: Isihlungi esisebenzayo sekhabhinethi ye-HYAPF

Olandelayo: Uchungechunge lwe-HYSVG idivayisi yesinxephezelo samandla asebenzayo anamandla kagesi aphezulu
