Nhanganyaya: SVG (Static Var Generator), kureva, high-voltage static var jenareta, inozivikanwawo seAdvanced static var compensator ASVC (Advanced Static Var Compensator) kana static compensator STATCOM (Static Compensator), SVG (static compensator) uye Iwo matatu -phase yakakwira-simba voltage inverter ndiyo musimboti, uye inobuda voltage yakabatana kune sisitimu kuburikidza nereactor, uye inochengeta yakafanana frequency nechikamu seyo system side voltage, uye simba rekubuda rinotemwa nekugadzirisa hukama pakati pezvinobuda. voltage amplitude uye system voltage amplitude Chimiro uye kugona kwe, kana amplitude yakakura kupfuura voltage amplitude yedivi resystem, inoburitsa capacitive reactive simba, uye kana idiki pane izvozvo, inoburitsa inductive reactive simba.Iyo inoreva zvakananga kune mudziyo weiyo dynamic reactive simba muripo neself-commutated power semiconductor bridge converters.
Saka ndeipi chiyero chekushandiswa kweSVG (static compensator)?
Chekutanga pane zvese, iyo inonyanya kushandiswa SVG (static compensator) inonyanya kushandiswa mune yakazvimirira magetsi grid system yevashandisi vemaindasitiri.Nekuti madhipatimendi akakodzera enyika, akadai sedhipatimendi remagetsi, achadzora simba remagetsi nemhando yemagetsi evashandisi veindasitiri ava.Pane zvakawanda zvinodzivisa uye zvinogumira.Izvi zvinoreva kunyanya izvo zvevashandisi veindasitiri.Kushandiswa kwesimba kwakanyanya.Vashandisi vanofanirwa kushandisa SVG (Static Compensator) kune in-situ reactive simba muripo.Kune rumwe rutivi, inogona kuderedza kushandiswa kwayo kwesimba uye kuzadzisa chinangwa chekuchengetedza simba uye kuderedza emission, kune rumwe rutivi.Kukwanisa kusvika kune magetsi emagetsi kune indasitiri.kupiwa.Simba chinhu uye simba remhando zvinodiwa.
SVG (static compensator) inonyanya kugadzirisa matambudziko anokonzerwa nemagetsi factor, voltage deviation, voltage fluctuation uye flicker.Saka SVG (static compensator) inogona kugadziriswa zvakakwana.Reactive power compensation maitiro ezvidyarwa zvemagetsi emhepo.Kunyanya nemamwe midziyo yemagetsi senge capacitors uye reactors.Nekushandiswa kwe.Inogona kuita kuti mutengo weiyo integrated reactive power compensation system udzikire.Panguva imwecheteyo, nekuda kwehukuru hudiki hweSVG (Static Compensator), ine kusimba kwakanaka.Pane zvishoma zvinoda kutarisirwa kwevanhu, izvo zvinobvumirawo mapurazi emhepo kuti avakwe pose paanenge ari.Kuvakwa panguva imwe chete kweSVG (Static Compensator).
Kune izvo zvinyoro zvinyoro zvinokonzeresa zvakakura zvemukati uye yakakwirira-yakarongeka maharmonics, semuenzaniso.Reactive kuvhunduka kunowanzoitika mumaindasitiri emagetsi masisitimu.Iyo inokonzeresa Gaussian kutsetseka uye padivi nhanho ichave iyo grid voltage.kugadzira mafungu akashatiswa.Sezvo SVG (static compensator) pachayo haisi sosi yeharmonics.panguva imwe.Iyo ine mabasa ekubhadhara reactive simba chinhu uye kubvisa yakanyura harmonics.
Panguva imwecheteyo, SVG (static compensator) inokodzerawo kune idzo nzvimbo uko michina yemagetsi inokonzeresa kusaenzana kwenhatu-chikamu.Iyo isina kuenzana yechitatu-chikamu chemagetsi gidhi ichaita yakakwira harmonics uye yakaipa sequence currents.Ita kuti kukanganiswa kwemagetsi kuve kwakaoma.Ichakonzera kushanduka kwevoltage uye flicker.SVG (Static Compensator).Ine kukurumidza kupindura nekukurumidza.Mhinduro yehurongwa iri pasi pe5ms, uye haingogone kupa yakagadzika grid voltage semidziyo yemagetsi.uye reactive ikozvino.Panguva imwecheteyo, inogonawo kubvisa kusaenzana kwezvikamu zvitatu nekushandisa yayo yega-sub-item compensation function.Kuvandudza mashandisirwo emidziyo yakadai sema traction transformers, uye panguva imwechete kudzvanyirira yakaderera-frequency oscillations muhurongwa.
SVG (static compensator) inotora tekinoroji yakawandisa kana yePWM kudzikisa zvakanyanya zvirimo mumaharmonics muripo wekubhadhara ikozvino, uye huwandu hwayo uye mutengo idiki zvakanyanya pane zvakajairika zvechinyakare condensers, capacitor reactor, uye thyristor-inodzorwa reactor TCR.Inomiririra yechinyakare SVC uye zvichingodaro.SVG static compensator ndiyo ramangwana rekusimudzira maitiro.
