I-MV SVC yokuSombulula iingxaki ze-Flickelharmonic kunye neDynamic Reactive Reactive

I-SVC yethu ibandakanya iindidi ezintathu ukuhlangabezana neemfuno zamashishini ahlukeneyo kunye neziza: i-MCR, i-TSC, kunye ne-TCR. Uhlobo lwe-MCR lwe-SVC luthatha i-self edityanisiweyo yokuvuselela i-DC kunye nokunciphisa imowudi yokusebenza yamagnetic saturation, enganciphisi kakhulu i-harmonics eveliswayo, kodwa inokulahlekelwa kwamandla asebenzayo kunye nesantya sokuphendula ngokukhawuleza. Ngokuguqula i-engile yokuqalisa i-thyristor kwinkqubo yokuvuselela i-MCR, iqondo lokuzalisa i-flux yamagnetic kumbindi we-reactor yokulawula magnetic inokuguqulwa, ngaloo ndlela itshintsha amandla asebenzayo aphumayo kwi-reactor yokulawula magnetic.

Uhlobo lwe-MCR lwe-SVC lunokuthembeka okuphezulu kakhulu, ukugcinwa simahla, kunye nobomi benkonzo obungekho ngaphantsi kweminyaka engama-20. Iinkqubo ezibalulekileyo ezifana nothungelwano lombane wokutsalwa komzila kaloliwe zinikwe ingqwalaselo ephambili ukuze zamkelwe; Iyakwazi ukusebenza ngokuzinzileyo kunye nokuthembekileyo kuyo nayiphi na indawo yokusebenza yegridi yamandla obunzima (njengokuphazamiseka kwe-voltage waveform, ukuguquguquka okukhulu kwe-amplitude, njl.); Iyakwazi ukusebenza ngokuthe ngqo kuyo nayiphi na igridi yamandla ombane (6-500kV), kwaye kulula ukuyifaka (ifana neziguquli eziqhelekileyo) kunye nokulungiswa; Umthamo wembuyekezo yamandla asebenzayo unokulungiswa ngokungenasiphelo ukuphumeza eyona mpembelelo ilungileyo.

iinkcukacha zemveliso

I-high-voltage TSC dynamic reactive imbuyekezo isixhobo amandla iquka inkqubo yolawulo, inkqubo ebangela, thyristor esweni inkqubo, ipulse transformer, capacitor, reactor, iyunithi yokukhusela, njl. Inkqubo yolawulo ibhaqa amandla asebenzayo enkqubo yamandla ngexesha lokwenyani, imisela ngokuzenzekelayo isebe le-capacitor elifuna ukutshintshelwa, kwaye emva koko ilawula iqela le-valve ye-capastor yesebe elilawulayo iqela. Le nkqubo ingentla izenzekelayo ngokupheleleyo, iqinisekisa ukuba akukho mpembelelo, ukunyuka, okanye utshintsho xa utshintshe i-capacitors.

Isixhobo sohlobo lwe-TCR uhlobo lwe-SVC ikakhulu luqulethwe ngamacandelo amabini: i-TCR (i-reactor elawulwa yi-thyristor) kunye ne-FC (i-filter capacitor bank) .Isekethe ye-FC idibanisa umsebenzi wokucoca kwaye inokubonelela nge-fixed capacitive amandla asebenzayo, ngelixa i-TCR isiphaluka sitshintsha i-inductive reactive power output ye-reactor elawulwa yi-phase ngokulawulwa kwe-thyristor. ixesha lokwenyani imbuyekezo eguquguqukayo yamandla asebenzayo inokufezekiswa. Ngokukodwa kwimigangatho emithathu yomthwalo we-arc arc, ukuguquguquka kombane kunye ne-flicker eyenziweyo inokuncitshiswa. Ngelo xesha, uhlobo lwe-TCR lwe-SVC lunomsebenzi wokulawula ukuhlukana kwesigaba, esinokulinganisa imithwalo engalinganiyo yezigaba ezintathu ze-AC arc furnaces kunye neminye imithwalo, kwaye icinezele icandelo elibi lokulandelelana kwegridi yamandla ukuya kubuncinci.

Iimveliso eziluncedo

• I-valve ye-thyristor ithatha i-photoelectric triggering method, kunye nokukhusela i-BOD ye-thyristor, ikhono elinamandla lokuchasana nokuphazamiseka, kunye nokukhusela okuthembekileyo;

• Uyilo lomzimba wevalvu wamkela uyilo oluthe tyaba, olunesixhobo esibambeneyo, ukusebenza okuthembekileyo, kunye nomthwalo onganeno wokulondolozwa;

• Unxibelelwano lwe-Fiber optic lusetyenziswa phakathi kwenkqubo yokulawula kunye neyunithi yamandla, okubangela ukuzinza komqondiso ophezulu;

• I-reactor elawulwa yi-thyristor inemisebenzi yokukhusela efana nokulahlekelwa kwamandla e-synchronous, ukulahleka kwe-pulse, ukungalingani kwe-pulse, kunye nokuphazamiseka kwe-thyristor.
