Lapho ekhetha imikhiqizo, amakhasimende amaningi avame ukungibuza ukuthi yiniI-SVGfuthi yini umehluko phakathi kwayo ne-SVC?Ake ngikunike isingeniso, ngithemba ukuthi kuzoba usizo ekukhetheni kwakho.
Ku-SVC, singacabanga ngayo njengomthombo wamandla asebenzayo.Inganikeza amandla asebenzayo e-capacitive kugridi yamandla ngokuya ngezidingo zokufinyelela kugridi yamandla, futhi ingakwazi nokumunca amandla asebenzayo asebenzayo egridi yamandla, futhi ibhange le-capacitor ngokuvamile lixhunywa kugridi yamandla njengebhange lokuhlunga. , enganikeza amandla asebenzayo kugridi yamandla.Uma igridi ingadingi amandla amaningi asebenzayo, la mandla asebenzayo e-capacitive angamuncwa i-reactor efanayo.I-reactor current ilawulwa yisethi ye-valve ye-thyristor.Ngokulungisa i-Angle yesigaba se-thyristor trigger, singashintsha inani elisebenzayo lamanje eligeleza ku-reactor, ukuze siqinisekise ukuthi amandla asebenzayo e-SVC endaweni yokungena yegridi angavele azinzise i-voltage yephoyinti ngaphakathi kwendawo eshiwo. ububanzi, futhi udlale indima yesinxephezelo samandla asebenzayo wegridi.
I-SVGiyithuluzi elivamile lamandla kagesi, elakhiwe amamojula amathathu ayisisekelo asebenzayo: imojula yokuthola, imojula yokusebenza yokulawula kanye nemojula yokukhipha isinxephezelo.Umgomo wayo wokusebenza ukuthola ulwazi lwamanje lwesistimu ye-CT yangaphandle, bese uhlaziya ulwazi lwamanje, njenge-PF, S, Q, njll, ngokusebenzisa i-chip yokulawula;Khona-ke isilawuli sinikeza isignali yedrayivu enxeshezelwe, futhi ekugcineni isifunda se-inverter esakhiwe amandla we-electronic inverter circuit sithumela okwamanje okunxeshezelwe.
II-SVG static varIjeneretha iqukethe isekethe yebhuloho elizihambelayo elakhiwe idivayisi kagesi yamandla okucisha (IGBT), exhunywe kugridi yamandla ngokuhambisana ne-reactor, kanye ne-amplitude nesigaba se-voltage ephumayo ohlangothini lwe-AC Isifunda sebhuloho singalungiswa kahle, noma esamanje ngasohlangothini lwe-AC singalawulwa ngokuqondile.Munca ngokushesha noma ukhiphe amandla asebenzayo adingekayo ukuze ufinyelele inhloso yokulungiswa okusheshayo kwamandla asebenzayo.Njengedivayisi yesinxephezelo esebenzayo, ayikwazi ukulandelela kuphela umfutho wamanje womthwalo we-impulse, kodwa futhi ulandelele futhi unxephezele okwamanje i-harmonic.
I-SVGkanye ne-SVC isebenza ngokuhlukile.I-SVG iyidivayisi yesinxephezelo samandla esebenzayo esuselwe kumadivayisi kagesi.Ilungisa amandla asebenzayo ngokulawula ukuvula nokuvala amandla emishini kagesi.I-SVC iyidivayisi yesinxephezelo samandla esebenzayo esekelwe kudivayisi esabelayo, elungisa amandla asebenzayo ngokulawula inani lokusabela le-reactor eguquguqukayo.Ngenxa yalokho, i-SVG inokusabela okusheshayo nokunemba okuphezulu, kuyilapho i-SVC inomthamo omkhulu nokusebenza okuzinzile.
I-SVG ne-SVC zilawulwa ngendlela ehlukile.I-Static var generatorisebenzisa imodi yokulawula yamanje, okungukuthi, ngokuya ngesigaba kanye nobukhulu bamanje ukuze ilawule amandla kagesi avuliwe futhi avaliwe.Le modi yokulawula ingafinyelela ukulungiswa okunembile kwamandla asebenzayo, kodwa idinga isivinini sokuphendula esiphezulu samanje.Futhi i-SVC yamukela imodi yokulawula i-voltage, okungukuthi, ngokuya ngesigaba kanye nobukhulu be-voltage ukulawula inani lokusabela kwe-reactor eguquguqukayo.Le modi yokulawula ingabona ukulungiswa okuzinzile kwamandla asebenzayo, kodwa idinga isivinini sokuphendula se-voltage ephezulu.
Ububanzi bokusetshenziswa kwe-SVG ne-SVC buhlukile.I-SVG ilungele izinhlelo zokusebenza ezidinga ukushintshashintsha kwamandla kagesi aphezulu, njengezitshalo zikagesi, iziteshi ezincane kanye namabhizinisi amakhulu ezimboni.Ingathuthukisa ukuqina kwamandla kagesi kanye nekhwalithi yamandla wesistimu yamandla ngokuphendula okusheshayo nokulawula okunembayo.I-SVC ilungele izinhlelo zokusebenza ezidinga ukuguquguquka okuphezulu kwamanje, njengezithando zomlilo ze-arc kagesi, ezokuthutha zikaloliwe nezimayini.Ingathuthukisa isici samandla nokuzinza kwesistimu yamandla nge
ukulungisa lamanje ngokuzinza.
