Isandulelo: I-SVG (Static Var Generator), okungukuthi, i-high-voltage static var generator, eyaziwa nangokuthi i-advanced static var compensator ASVC (Advanced Static Var Compensator) noma isinxephezelo esimile STATCOM (Static Compensator), SVG (isinxephezelo esimile) kanye Nezintathu I-inverter ye-voltage yesigaba samandla aphezulu iwumgogodla, futhi i-voltage yayo ephumayo ixhunywe ohlelweni nge-reactor, futhi igcina imvamisa nesigaba esifanayo ne-voltage yohlangothi lwesistimu, futhi amandla okukhiphayo anqunywa ngokulungisa ubudlelwano phakathi kokuphumayo. I-voltage amplitude kanye nesistimu ye-voltage amplitude Imvelo kanye nomthamo we-, lapho i-amplitude yayo inkulu kune-voltage amplitude yohlangothi lwesistimu, izokhipha amandla asebenzayo we-capacitive, futhi uma incane kunalokho, izokhipha amandla asebenzayo asebenzayo.Iqondise ngokuqondile kudivayisi yesinxephezelo samandla asebenzayo aguqukayo ngeziguquli zebhuloho le-semiconductor yamandla azishintshayo.
Ngakho-ke ingakanani ububanzi bokusetshenziswa kwe-SVG (isinxephezelo esimile)?
Okokuqala, i-SVG evame ukusetshenziswa kakhulu (i-static compensator) isetshenziswa kakhulu ohlelweni oluzimele lwegridi yabasebenzisi bezimboni.Ngoba iminyango efanele yezwe, njengomnyango wokuphakelwa kukagesi, izolawula isici sikagesi kanye nekhwalithi yamandla alaba basebenzisi bezimboni.Kunezithiyo eziningi kanye nemikhawulo.Lokho kusho ikakhulukazi lezo zabasebenzisi bezimboni.Ukusetshenziswa kwamandla kuphezulu kakhulu.Abasebenzisi badinga ukusebenzisa i-SVG (Static Compensator) ukuze bathole isinxephezelo samandla asebenzayo asendaweni.Ngakolunye uhlangothi, inganciphisa ukusetshenziswa kwayo kwamandla futhi ifinyelele inhloso yokonga amandla nokunciphisa ukukhishwa, ngakolunye uhlangothi.Ikwazi ukufinyelela umkhakha wokuphakelwa kukagesi embonini.inikezwe.Isici samandla nezidingo zekhwalithi yamandla.
I-SVG (i-static compensator) ihamba phambili ekuxazululeni izinkinga ezibangelwa isici samandla, ukuchezuka kwe-voltage, ukuguquguquka kwamandla kagesi kanye nokucwayiza.Ngakho i-SVG (isinxephezelo esimile) ingaxazululwa ngokuphelele.Ukuziphatha kwesinxephezelo samandla asebenzayo wezitshalo zamandla omoya.Ikakhulukazi nezinye izinto zikagesi ezifana nama-capacitor nama-reactors.Ngokusetshenziswa kwe.Ingenza izindleko zesistimu yesinxephezelo samandla asebenzayo ahlanganisiwe abe phansi.Ngesikhathi esifanayo, ngenxa yobukhulu obuncane be-SVG (Static Compensator), inokuqina okuhle.Asikho isidingo sokugadwa kwabantu, okwenza ukuthi amapulazi omoya akhelwe noma yikuphi lapho ekhona.Ukwakhiwa ngesikhathi esisodwa kwe-SVG (Static Compensator).
Kuleyo mithombo ye-harmonic ebangela okuqukethwe okukhulu nama-harmonics we-oda eliphezulu, isibonelo.Ukushaqeka okusebenzayo kuvame ukwenzeka ezinhlelweni zikagesi zezimboni.Umphumela we-Gaussian slope kanye neleveli eseceleni kuzoba amandla kagesi wegridi.khiqiza amagagasi ahlanekezelwe.Njengoba i-SVG (i-static compensator) ngokwayo ayiwona umthombo wama-harmonics.ngesikhathi esifanayo.Inemisebenzi yokunxephezela isici samandla asebenzayo kanye nokuqeda ama-harmonics amuncwe.
Ngesikhathi esifanayo, i-SVG (i-static compensator) ibuye ifanele lezo zindawo lapho imishini kagesi izobangela ukungalingani kwezigaba ezintathu.Igridi yamandla yezigaba ezintathu engalingani izokhiqiza ama-harmonic aphezulu kanye nama-currents alandelanayo angalungile.Yenza ukuhlanekezela kwamandla kagesi kube nzima kakhulu.Izodala ukushintshashintsha kwe-voltage kanye nokucwayiza.I-SVG (Isinxephezelo Esimile).Inesivinini sokuphendula esishesha kakhulu.Impendulo yesistimu ingaphansi kuka-5ms, futhi ayikwazi ukuhlinzeka ngogesi wegridi ozinzile njengamathuluzi kagesi.kanye namandla asebenzayo.Ngesikhathi esifanayo, ingaphinda isuse ukungalingani kwezigaba ezintathu ngokusebenzisa umsebenzi wayo wesinxephezelo sezinto ezingaphansi.Thuthukisa ukusetshenziswa kwemishini efana nama-traction transformer, futhi ngesikhathi esifanayo ucindezele ama-oscillations aphansi ohlelweni.
I-SVG (i-static compensator) isebenzisa ubuchwepheshe obuhlukahlukene noma be-PWM ukunciphisa kakhulu okuqukethwe kwe-harmonics kumanje wesinxephezelo, futhi umthamo wayo nezindleko zincane kakhulu kunezikhondezeli ezivamile zendabuko, ama-capacitor reactor, kanye ne-TCR elawulwa yi-thyristor.Imele i-SVC yendabuko nokunye.I-SVG static compensator inkambiso yentuthuko yesikhathi esizayo.
