Intshayelelo: SVG (Static Var Generator), oko kukuthi, high-voltage static var jenereyitha, eyaziwa ngokuba advanced static var compensator ASVC (Advanced Static Var Compensator) okanye static compensator STATCOM (Static Compensator), SVG (static compensator) kunye The ezintathu I-inverter ye-high-power voltage ingundoqo, kwaye i-voltage yayo yokuphuma iqhagamshelwe kwinkqubo nge-reactor, kwaye igcina i-frequency kunye nesigaba njenge-voltage yecala lenkqubo, kwaye amandla aphumayo amiselwa ngokulungelelanisa ubudlelwane phakathi kwemveliso. I-voltage amplitude kunye ne-system ye-voltage amplitude Ubume kunye nomthamo we-, xa i-amplitude yayo inkulu kune-voltage amplitude yecala lenkqubo, iya kukhupha amandla asebenzayo e-capacitive, kwaye xa incinci kunoko, iya kukhupha amandla asebenzayo asebenzayo.Ibhekiselele ngokukodwa kwisixhobo sembuyekezo yamandla aguqukayo ngokuzitshintsha-tshintsha amandla okuguquguqula ibhulorho ye-semiconductor.
Ke ngoko uthini umda wosetyenziso lwe-SVG (i-static compensator)?
Okokuqala, eyona SVG isetyenziswa ngokuqhelekileyo (i-static compensator) isetyenziswa kakhulu kwinkqubo yegridi yamandla ezimeleyo yabasebenzisi bemizi-mveliso.Kuba amasebe afanelekileyo elizwe, afana nesebe lobonelelo ngombane, aya kulawula umba wombane kunye nomgangatho wamandla waba basebenzisi bemizi-mveliso.Kukho imiqobo emininzi kunye nemida.Oko kuthetha ngakumbi abo babasebenzisi bemizi-mveliso.Ukusetyenziswa kwamandla kuphezulu kakhulu.Abasebenzisi kufuneka basebenzise iSVG (Static Compensator) kwimbuyekezo yamandla asebenzayo angaphakathi.Ngakolunye uhlangothi, inokunciphisa ukusetyenziswa kwamandla ayo kwaye ifezekise injongo yokonga amandla kunye nokunciphisa ukukhutshwa, kwelinye icala.Ukwazi ukufikelela kwicandelo lonikezelo lwamandla kushishino.inikwe.Umba wamandla kunye neemfuno zomgangatho wamandla.
I-SVG (i-static compensator) yeyona nto ingcono ekusombululeni iingxaki ezibangwe sisimo samandla, ukutenxa kombane, ukuguquguquka kombane kunye nokuqhwanyaza.Ke i-SVG (i-static compensator) inokusombulula ngokugqibeleleyo.Ukuziphatha kwembuyekezo yamandla asebenzayo kwizityalo zamandla omoya.Ngokukodwa kunye nezinye izixhobo zombane ezifana ne-capacitors kunye ne-reactors.Ngokusetyenziswa kwe.Inokwenza iindleko zenkqubo yembuyekezo yamandla asebenzayo adibeneyo asezantsi.Kwangaxeshanye, ngenxa yobungakanani obuncinci beSVG (Static Compensator), inokuqina okuhle.Kukho imfuneko encinane yolawulo lwabantu, nto leyo evumela ukuba iifama zomoya zakhiwe naphi na apho zikhoyo.Ulwakhiwo ngaxeshanye lwe-SVG (i-Static Compensator).
Kuloo mithombo ye-harmonic ebangela umxholo omkhulu kunye ne-harmonics ephezulu, umzekelo.Izothuso ezisebenzayo zihlala zisenzeka kwiinkqubo zombane kwimizi-mveliso.Isiphumo se-Gaussian slope kunye nenqanaba lecala liya kuba yi-voltage yegridi.velisa iimo zamaza ezigqwethekileyo.Ekubeni i-SVG (i-static compensator) ngokwayo ayingomthombo we-harmonics.ngaxeshanye.Inemisebenzi yokubuyisela amandla asebenzayo kunye nokuphelisa i-harmonics efunliweyo.
Ngelo xesha, i-SVG (i-static compensator) nayo ifanelekile kwezo ndawo apho izixhobo zombane ziza kubangela ukungalingani kwesigaba sesithathu.Igridi yamandla engalungelelananga yamanqanaba amathathu iya kuvelisa i-harmonics ephezulu kunye nemisinga yolandelelwano olubi.Yenza ukuphazamiseka kombane kube nzima ngakumbi.Iya kubangela ukuguquguquka kwamandla ombane kunye ne-flicker.I-SVG (i-Static Compensator).Inesantya sokuphendula esikhawulezayo.Impendulo yenkqubo ingaphantsi kwe-5ms, kwaye ayikwazi ukubonelela kuphela amandla ombane wegridi ezinzileyo njengezixhobo zombane.kunye nentshukumo yangoku.Ngexesha elifanayo, inokuphelisa ukungalingani kwezigaba ezintathu ngokusebenzisa umsebenzi wayo wembuyekezo ye-sub-item.Ukuphucula ukusetyenziswa kwezixhobo ezifana neziguquli zokutsala, kwaye kwangaxeshanye ucinezele i-oscillations ephantsi-frequency kwinkqubo.
I-SVG (i-static compensator) ithatha iteknoloji eninzi okanye ye-PWM ukunciphisa kakhulu umxholo we-harmonics kwimbuyekezo yangoku, kwaye umthamo wayo kunye neendleko zincinci kakhulu kune-condensers eziqhelekileyo eziqhelekileyo, i-capacitor reactors, kunye ne-thyristor-controlled reactors TCR.Imele iSVC yemveli njalo njalo.I-SVG static compensator yindlela yophuhliso yexesha elizayo.
