Ukuphonononga i-Advanced Static Var Generators: Ukuguqula izisombululo zoMgangatho waMandla

Kwihlabathi lanamhlanje elihambele phambili kwezobuchwepheshe, ukubaluleka kokuqinisekisa umgangatho wamandla angowona uphezulu akunakugxininiswa ngokugqithisileyo.Ukuguquguquka kwamandla, ukuphazamiseka kwe-harmonic kunye nemiba yamandla asebenzayo ihlala ikhokelela ekonakaleni kwezixhobo, ukunciphisa ukusebenza kakuhle kunye nokwanda kokulahleka kwamandla.Kodwa ungakhathazeki, kuba isisombululo esiphumeleleyo siye savela ukuhlangabezana nale mingeni ngokuthe ngqo - iIjenereyitha yeVar eNgqongileyo (ASVG).Kule bhlog, siza kuntywila kwiimpawu eziphambili kunye nezibonelelo ze-ASVG, kunye nendlela enokuziguqula ngayo izisombululo zomgangatho wamandla.

Amandla embuyekezo yamandla asebenzayo:
I-ASVG yimveliso yokusika emele usetyenziso lwetekhnoloji yamva nje kwicandelo lembuyekezo yamandla asebenzayo.Ngokuhlengahlengisa ngamandla isigaba kunye ne-amplitude ye-voltage yokuphuma okanye ukulawula okwangoku kwicala le-AC le-inverter, amandla asebenzayo afunekayo kunye nomthamo we-harmonic unokufunxwa ngokukhawuleza okanye uhanjiswe.Olu phawu lukhethekileyo luqinisekisa uhlengahlengiso olukhawulezayo oluguquguqukayo lwamandla asebenzayo kunye nembuyekezo esebenzayo ye-harmonic, iyahlula kwizisombululo zemveli.

Ukusebenza okungenakulinganiswa kunye nokuguquguquka:
Njengoko iinkqubo zamandla zisiba nzima ngakumbi, kubalulekile ukuba ube nezisombululo eziguquguqukayo, eziphezulu zokusebenza ezilungelelanisa iimfuno zomthwalo ohlukeneyo.I-ASVG igqwesile koku, ibonelela ngeempendulo ezikhawulezileyo nezisebenzayo kwimiba yobulunga bamandla kuzo zombini iinkqubo zamandla ombane aphezulu naphantsi.Uyilo lwayo lweemodyuli luvumela ukulungelelaniswa okulula kunye nokulinganisa, okwenza ukuba ilungele usetyenziso oluhlukeneyo kunye namashishini.Nge-ASVG, unokuphucula umgangatho wamandla, ukwandisa ubomi besixhobo, kunye nokunciphisa ukulahleka kwamandla, konke kwiphakheji edibeneyo kunye nethembekileyo.

Landa kwaye ubuyekeze i-reactive current kunye ne-harmonic yangoku:
Enye yeempawu ezibalaseleyo ze-ASVG kukukwazi ukulandelela ngokuchanekileyo kunye nokuhlawula imisinga esebenzayo kunye ne-harmonic.Ngokungafaniyo nezisombululo zemveli, ezihlala zijolise kuphela kwimbuyekezo yamandla asebenzayo, i-ASVG ingaphezulu koko.Ayiqinisekisi kuphela ukuba umbane osebenzayo womthwalo ulawulwa kakuhle, kodwa uphinda usombulule ingxaki enzima yokunciphisa i-harmonic currents.Ngokwenza njalo, unokugcina inkqubo yakho yombane isebenza ngokufanelekileyo nangokufanelekileyo, ukunciphisa umngcipheko wokungaphumeleli kwezixhobo kunye nokuqinisekisa ukusebenza okungaphazanyiswa.

Eyona ndleko isebenzayo:
Ukutyala imali kwisisombululo somgangatho wamandla akufuneki kwaphule ipokotho yakho.I-ASVG igqwesile koku, ibonelela ngendlela eneendleko ngaphandle kokuthomalalisa ukusebenza okanye ukuthembeka.Ngobuchwephesha obuphezulu kunye nesixhobo solawulo olukrelekrele, izixhobo zamandla zisetyenziswa ngokufanelekileyo, okukhokelela kukongiwa kwamandla okubalulekileyo.Kwaye, imo yemodyuli yayo ithetha ukuba ungaqala ngesikhundla osidingayo kwaye wandise njengoko inkqubo yakho yamandla ikhula, unqanda iindleko ezingeyomfuneko zangaphambili kunye nokuqinisekisa ukuqina.

ukuququmbela:
IIjenereyitha yeVar eNgqongileyo (ASVG)ngumtshintshi womdlalo kwintsimi yomgangatho wamandla.Ubuchule bayo obukhethekileyo bokulungelelanisa amandla asebenzayo kunye ne-harmonics buwenza ahluke kwizisombululo zemveli.Nokuba ujongene neenkqubo zamandla ezintsonkothileyo okanye ujonge ukuphucula ubomi bezixhobo kunye nokusebenza kakuhle kwamandla, i-ASVG ibonelela ngesisombululo esona siphumo.Ukusebenza kwayo okungenakuthelekiswa nanto, ukuguquguquka kunye nokusebenza kakuhle kweendleko kuyenza ibe lukhetho lokuqala kuwo wonke amashishini.Yamkela amandla e-ASVG ukuzisa uzinzo olungazange lubonwe ngaphambili kunye nokusebenza kakuhle kwinkqubo yakho yamandla.
