Xa ukhetha iimveliso, abathengi abaninzi bahlala bendibuza ukuba yintoni naSVGkwaye yintoni umahluko phakathi kwayo kunye ne-SVC?Makhe ndikunike intshayelelo, ndiyathemba ukuba iya kuba luncedo kukhetho lwakho.
Kwi-SVC, sinokucinga ngayo njengomthombo wamandla osebenzayo.Inokubonelela nge-capacitive reactive power kwigridi yamandla ngokweemfuno zofikelelo kwigridi yamandla, kwaye inokufunxa amandla asebenzayo asebenzayo egridi yamandla, kwaye ibhanki ye-capacitor ihlala iqhagamshelwe kwigridi yamandla njengebhanki yokucoca. , enokubonelela ngamandla asebenzayo kwigridi yamandla.Xa igridi ayifuni amandla amaninzi asebenzayo, le capacitive engasebenziyo yamandla esebenzayo inokufunxwa yireactor ehambelanayo.I-reactor current ilawulwa yisethi yevalve ye-thyristor.Ngokulungelelanisa i-Angle yesigaba se-thyristor, sinokutshintsha ixabiso elisebenzayo langoku elihambayo kwi-reactor, ukuze kuqinisekiswe ukuba amandla asebenzayo e-SVC kwindawo yokufikelela kwigridi angakwazi nje ukuzinzisa umbane wenqaku ngaphakathi kwendawo echaziweyo. uluhlu, kwaye udlale indima yembuyekezo yamandla asebenzayo wegridi.
SVGsisixhobo sombane esiqhelekileyo samandla, esiqulunqwe ziimodyuli ezintathu ezisisiseko ezisebenzayo: imodyuli yokufumanisa, imodyuli yokusebenza yolawulo kunye nemodyuli yokuphuma kwembuyekezo.Umgaqo wayo wokusebenza kukufumanisa ulwazi lwangoku lwenkqubo ye-CT yangaphandle, kwaye emva koko uhlalutye ulwazi lwangoku, njenge-PF, S, Q, njl., ngokusebenzisa i-chip yokulawula;Emva koko umlawuli unika isignali ye-drive ehlawulwayo, kwaye ekugqibeleni i-inverter circuit eyakhiwe ngamandla e-electronic inverter circuit ithumela umbane ohlawulelwayo.
II-SVG static varIjenereyitha iqulathe isekethe yebhulorho ezitshintshayo eyenziwe sisisixhobo sombane esicinyiweyo (IGBT), esiqhagamshelwe kwigridi yamandla ngokunxuseneyo kwireactor, kunye neamplitude kunye nesigaba sombane ophumayo kwicala le-AC Isekethe yebhulorho inokulungelelaniswa ngokufanelekileyo, okanye okwangoku kwicala le-AC linokulawulwa ngokuthe ngqo.Ukufunxa ngokukhawuleza okanye ukukhupha amandla asebenzayo afunekayo ukufezekisa injongo yohlengahlengiso olukhawulezayo lwamandla asebenzayo.Njengesixhobo sembuyekezo esebenzayo, ayinakukwazi ukulandelela kuphela i-impulse current yomthwalo we-impulse, kodwa iphinde ilandele kwaye ihlawule i-harmonic current.
SVGkunye ne-SVC isebenza ngokwahlukileyo.I-SVG sisixhobo sembuyekezo yamandla esebenzayo esekwe kwizixhobo zombane.Ilungelelanisa amandla asebenzayo ngokulawula ukuvula nokucima izixhobo zombane zombane.I-SVC sisixhobo sembuyekezo yamandla esebenzayo esekwe kwisixhobo sokuphendula, esilungisa amandla asebenzayo ngokulawula ixabiso le-reactance ye-reactor variable.Ngenxa yoko, i-SVG inempendulo ekhawulezayo kunye nokuchaneka okuphezulu, ngelixa i-SVC inomthamo omkhulu kunye nokusebenza okuzinzile.
I-SVG kunye ne-SVC zilawulwa ngokwahlukileyo.Static var generatorisebenzisa imo yolawulo lwangoku, oko kukuthi, ngokwesigaba kunye ne-amplitude yangoku ukulawula i-electronics power on and off.Le ndlela yokulawula inokufezekisa uhlengahlengiso oluchanekileyo lwamandla asebenzayo, kodwa ifuna isantya esiphezulu sokuphendula sangoku.Kwaye i-SVC ithatha imo yokulawula i-voltage, oko kukuthi, ngokwesigaba kunye ne-amplitude ye-voltage ukulawula ixabiso le-reactance ye-reactor variable.Le mowudi yokulawula inokuqonda uhlengahlengiso oluzinzileyo lwamandla asebenzayo, kodwa ifuna isantya sokuphendula amandla ombane aphezulu.
Umda wokusetyenziswa kwe-SVG kunye ne-SVC nayo yahlukile.I-SVG ilungele izicelo ezifuna ukuguquguquka okuphezulu kwamandla ombane, okufana nezixhobo zombane, izitishi ezincinci kunye namashishini amakhulu emizi-mveliso.Inokuphucula ukuzinza kwamandla ombane kunye nomgangatho wamandla wenkqubo yamandla ngokuphendula ngokukhawuleza kunye nolawulo oluchanekileyo.I-SVC ilungele izicelo ezifuna ukuguquguquka okuphezulu kwangoku, okufana neziko zombane ze-arc, ukuhamba ngololiwe kunye nemigodi.Inokuphucula into yamandla kunye nokuzinza kwenkqubo yamandla ngo
ukulungelelanisa yangoku ngokuzinzileyo.
