I-SVG 3-35KV 1-100Mvar isixhobo sembuyekezo yamandla ombane aphezulu
Ingcaciso yeMveliso
I-SVG yi-static var compensator, eyimveliso emele yesicelo sobugcisa kwintsimi yembuyekezo yamandla asebenzayo.I-TDSVG idityaniswe ngokunxuseneyo negridi yamandla, elingana nomthombo osebenzayo oguqukayo wangoku.Ngokulungelelanisa i-amplitude kunye nesigaba se-voltage yemveliso kwicala le-AC le-inverter, okanye ukulawula ngokuthe ngqo i-amplitude kunye nesigaba somlinganiselo wayo wangoku we-AC, unokukhawuleza ukufunxa okanye ukhuphe konke ukulungiswa kwamandla asebenzayo.Xa ulawulo lwangoku oluthe ngqo lwamkelwa, kungekhona nje kuphela ukunyanzeliswa komthwalo we-impulse ukulandelwa kunye nokuhlawulwa, kodwa kunye ne-harmonic current inokulandelwa kwaye ihlawule.Ukusebenzisa iteknoloji yokuguqula i-elektroniki ukuvelisa umsinga olingana kunye nochasene nento ehlawulwayo, iyacima enye kwenye, kwaye i-factor yamandla ingaba kufutshane ne-1.

Iimpawu zemveliso
(1) Inomsebenzi we-anti-harmonic ukuqinisekisa ukhuseleko lwenkqubo.I-TDSVG ngumthombo okhoyo olawulwayo, ohlawula kuphela umbane osebenzayo osebenzayo, kwaye i-harmonic current yenkqubo ayiyi kubangela umonakalo kwisixhobo sembuyekezo, ukwandisa ubomi bayo kunye nokunciphisa umsebenzi wokulondoloza.Kwangaxeshanye, ukuphepha ukukhulisa harmonic enokuthi kubangelwa capacitor bank of the reactionance series, kwaye uthintele ezinye izixhobo kunye nezixhobo imbuyekezo kwinkqubo ukuba zonakaliswe ngenxa overvoltage harmonic;
(2) Imbuyekezo egudileyo eqhubekayo, isantya esiphezulu sokuphendula senza ukuba umphumo wembuyekezo wombane ube ngcono.I-TDSVG inokulandela utshintsho lomthwalo, ngokuguquguqukayo kwaye ngokuqhubekayo ihlawule into yamandla, inokuvelisa amandla asebenzayo, kwaye inokufunxa amandla asebenzayo, iyisuse ngokupheleleyo imeko yamandla asebenzayo ngasemva;
(3) Inokusombulula ingxaki yomthwalo ongalinganiyo;
(4) Ayipheleli nje ekuveliseni i-harmonics, kodwa inokuthi ihlawule ngokuguquguqukayo kwii-harmonics ngelixa ihlawula amandla asebenzayo;
(5) Iimpawu zemithombo yangoku, i-output reactive current ayichatshazelwa yi-voltage yebhasi, kubandakanywa neempawu zohlobo lwe-impedance, i-output current iyancipha ngokuhambelana nombane webhasi;
(6) Akukho mpembelelo yesikhashana, akukho ukuvala i-inrush yangoku, akukho ukuvutha kwakhona kwe-arc ngexesha lokutshintsha, kwaye inokutshintshwa kwakhona ngaphandle kokukhutshwa;
(7) Ukugcinwa okuncinci kunye neendleko eziphantsi zokusebenza;
(8) Kulula ukuyifaka, ukuseta kunye nokucoca, kwaye ujongano lucacile kwaye lucacile.
Ukusetyenziswa kwemveliso kunye neenzuzo
