I-SVG 3-35KV 1-100Mvar idivayisi yesinxephezelo samandla anamandla anamandla aqinile
Incazelo Yomkhiqizo
I-SVG iyisinxephezelo se-var esimile, okuwumkhiqizo omele wohlelo lokusebenza lobuchwepheshe emkhakheni wesinxephezelo samandla asebenzayo.I-TDSVG ixhunywe ngokuhambisana negridi yamandla, elingana nomthombo wamanje osebenzayo oguquguqukayo.Ngokulungisa i-amplitude nesigaba se-voltage ephumayo ohlangothini lwe-AC lwe-inverter, noma ukulawula ngokuqondile i-amplitude nesigaba sesilinganiso sayo samanje se-AC, ingakwazi ukumunca ngokushesha noma ikhiphe wonke Amandla asebenzayo adingekayo angafinyelela inhloso yokusheshisa nokuguquguqukayo. ukulungiswa kwamandla asebenzayo.Uma ukulawulwa kwamanje okuqondile kwamukelwa, akukhona nje kuphela ukuthi i-inrush current yomthwalo we-impulse ingalandelelwa futhi inxeshezelwe, kodwa futhi i-harmonic current ingalandelelwa futhi inxeshezelwe.Ukusebenzisa ubuchwepheshe be-inverter ye-elekthronikhi yamandla ukukhiqiza imanje elilingana neliphambene nento enxeshezelwayo, kukhansela ngaphandle, futhi isici samandla singasondela ku-1.
Incazelo Yemodeli

Izici zomkhiqizo
(1) Inomsebenzi we-anti-harmonic wokuqinisekisa ukuphepha kohlelo.I-TDSVG ingumthombo wamanje olawulekayo, onxephezela kuphela amandla asebenzayo ayisisekelo, futhi i-harmonic current yesistimu ngeke ibangele umonakalo kumpahla yesinxephezelo, yandise ukuphila kwayo futhi yehlise umthwalo wokulungisa.Ngesikhathi esifanayo, gwema ukukhulisa i-harmonic okungenzeka kubangelwe ibhange le-capacitor lokusabela kochungechunge, futhi uvimbele ezinye izinto zokusebenza kanye nemishini yesinxephezelo ohlelweni ukuthi ingalinyazwa ngenxa yokugcwala kwe-harmonic;
(2) Isinxephezelo esisheshayo esiqhubekayo esibushelelezi, isivinini sokuphendula esiphezulu senza umphumela wokunxephezela ngokucwayiza kwamandla kagesi ube ngcono.I-TDSVG ingalandela izinguquko zomthwalo, inxephezele ngamandla nangokuqhubekayo isici samandla, ingakhiqiza amandla asebenzayo, futhi ingakwazi ukumunca amandla asebenzayo, isuse ngokuphelele isimo samandla asebenzayo emuva;
(3) Ingaxazulula inkinga yomthwalo ongalingani;
(4) Akukhona nje kuphela ukuthi akukhiqizi ama-harmonics, kodwa futhi kunganxephezela ngokuguquguqukayo kuma-harmonics ngenkathi kunxephezela amandla asebenzayo;
(5) Izici zamanje zomthombo, amandla asebenzayo aphumayo akuthintwa ugesi webhasi, okuhlanganisa izici zohlobo lwe-impedance, okukhiphayo kwamanje kuncipha ngokuhambisana ne-voltage yebhasi;
(6) Awukho umthelela wesikhashana, akukho ukuvala kwe-inrush current, akukho ukuvutha kabusha kwe-arc ngesikhathi sokushintsha, futhi ingashintshwa futhi ngaphandle kokukhishwa;
(7) Ukunakekela okuncane kanye nezindleko eziphansi zokusebenza;
(8) Kulula ukufaka, ukusetha nokulungisa iphutha, futhi isixhumi esibonakalayo sicacile futhi sicacile.
Isicelo somkhiqizo kanye nezinzuzo
Izicelo Ezijwayelekile
I-SVG inezinhlelo zokusebenza eziningi ezinamandla kagesi aphansi futhi aphezulu lapho ukusetshenziswa kwazo kunikeza izinzuzo eziningi.
⦿ Ukufakwa okunesidingo esiguqukayo samandla asebenzayo esishintshayo njengeziko likagesi ze-arc nezigayo zamabhola.
⦿ Imithwalo enamandla kakhulu lapho isici samandla siguquguquka ngokushesha noma ezinyathelweni ezinkulu njengama-cranes, imishini yokugaya, imishini yokushisela, njll.
⦿ Ukulungiswa kwezinto ezihamba phambili zamandla njengasezindaweni zedatha ezivumela ukusebenza kwamajeneretha asekelayo.

Izinzuzo zama-Static Var Generator (SVG):
1. Ikhono lokuletha isinxephezelo samandla asebenzayo kanye ne-inductive.
2. Kwenzelwe izinhlelo zokusebenza ezinamandla kakhulu lapho amabhange ama-capacitor ajwayelekile noma amabhange e-reactor engakwazi ukulandelela imithwalo.
3. Vumela isinxephezelo semithwalo ephakelwa amajeneretha ngaphandle kwengozi yokunxeshezelwa ngokweqile.
4. Faka amandla asebenzayo adingwa umthwalo ngaso leso sikhathi ohlelweni.
5. Ubukhulu obungaphezulu akudingekile: Umthamo wesinxephezelo ulingana nomthamo ofakiwe.
6. Akuthintwa ukwehla kwamandla kagesi enethiwekhi.Amandla asebenzayo aphelele anganikezwa ukuze ahlangabezane nesidingo esidingekayo ngaphansi kwezinga elincishisiwe lamandla kagesi wenethiwekhi.
