I-MV SVC yokuxazulula izinkinga ze-Flickelharmonic kanye ne-Dynamic Reactive Compensation

I-SVC yethu ihlanganisa izinhlobo ezintathu zokuhlangabezana nezidingo zezimboni namasayithi ahlukene: i-MCR, i-TSC, ne-TCR. I-MCR yohlobo lwe-SVC ithatha i-self-compated DC excitation futhi ikhawulele imodi yokusebenza yamagnetic saturation, engagcini nje ngokunciphisa kakhulu ama-harmonics akhiqiziwe, kodwa futhi enokulahlekelwa kwamandla asebenzayo aphansi kanye nesivinini sokuphendula ngokushesha. Ngokushintsha i-engeli yokucupha ye-thyristor kusistimu ye-MCR evusa amadlingozi, idigri yokugcwaliswa kwe-flux kazibuthe kumongo we-reactor yokulawula kazibuthe ingashintshwa, ngaleyo ndlela kuguqule amandla asebenzayo aphumayo we-reactor yokulawula kazibuthe.

I-MCR yohlobo lwe-SVC inokwethenjelwa okuphezulu kakhulu, mahhala ukugcinwa, kanye nempilo yesevisi engaphansi kweminyaka engama-20. Amasistimu abalulekile afana namanethiwekhi okuphakelwa kukagesi kaloliwe ohamba ngogesi anikezwe indawo yokuqala ukuze asetshenziswe; Iyakwazi ukusebenza okuzinzile nokuthembekile kunoma iyiphi indawo yokusebenza yegridi yamandla enokhahlo (njengokuhlanekezela kwe-voltage waveform, ukushintshashintsha kwe-amplitude enkulu, njll.); Ingasebenza ngokuqondile kunoma iyiphi igridi yamandla ezinga le-voltage (6-500kV), futhi kulula ukuyifaka (efana nama-transformer ajwayelekile) kanye nokulungisa iphutha; Umthamo wesinxephezelo samandla asebenzayo ungalungiswa ngokungenamkhawulo ukuze kuzuzwe umphumela wesinxephezelo ongcono kakhulu.

imininingwane yomkhiqizo

Idivayisi yesinxephezelo samandla asebenzayo anamandla e-TSC anamandla anamandla asebenzayo aqukethe isistimu yokulawula, isistimu yokucupha, isistimu yokuqapha i-thyristor, i-pulse transformer, i-capacitor, i-reactor, iyunithi yokuvikela, njll. Uhlelo lokulawula luthola amandla asebenzayo esistimu yamandla ngesikhathi sangempela, inquma ngokuzenzakalelayo igatsha le-capacitor elidinga ukushintshwa, bese lilawula iqembu elihambisanayo le-valve ye-valve iqembu. Inqubo engenhla i-othomathikhi ngokuphelele, iqinisekisa ukuthi akukho mthelela, ukukhuphuka, noma ukuguquka lapho ushintsha ama-capacitor.

Idivayisi ye-TCR yohlobo lwe-SVC ngokuyinhloko iqukethe izingxenye ezimbili: i-TCR (i-thyristor controlled reactor) ne-FC (filter capacitor bank) .Isifunda se-FC sihlanganisa umsebenzi wokuhlunga futhi singanikeza amandla asebenzayo e-capacitive, kuyilapho isifunda se-TCR sishintsha ukuphuma kwamandla asebenzayo we-reactor elawulwa yisigaba ngokusebenzisa isilawuli se-thyristor.Ngenxa yokushesha kakhulu kwe-capacitor bank). isinxephezelo esiguqukayo sesikhathi sangempela samandla asebenzayo singafinyelelwa. Ikakhulukazi ezigabeni ezintathu zokulayishwa kwesithando somlilo se-AC, ukushintshashintsha kwamandla kagesi kanye nokucwayiza okukhiqizwa kungancishiswa. Ngesikhathi esifanayo, uhlobo lwe-TCR lwe-SVC lunomsebenzi wokulawula ukuhlukaniswa kwesigaba, ongalinganisa imithwalo engalingani yezigaba ezintathu ze-AC arc furnaces neminye imithwalo, futhi icindezele ingxenye yokulandelana okungekuhle kwegridi yamandla ibe ubuncane.

Inzuzo Yemikhiqizo

• I-valve ye-thyristor ithatha indlela yokuqalisa i-photoelectric, ngokuvikelwa kwe-thyristor BOD, ikhono eliqinile lokulwa nokuphazamiseka, nokuvikelwa okuthembekile;

• Idizayini ye-valve yomzimba yamukela idizayini evundlile, enemishini ehlangene, ukusebenza okuthembekile, nomthwalo wokulungisa omncane;

• Ukuxhumana kwe-Fiber optic kusetshenziswa phakathi kwesistimu yokulawula kanye neyunithi yamandla, okuholela ekuzinzeni kwesignali ephezulu;

• I-reactor elawulwa yi-thyristor inemisebenzi yokuvikela efana nokulahlekelwa amandla ahambisanayo, ukulahlekelwa ukushaya kwenhliziyo, ukungalingani kwe-pulse, kanye nokuphazamiseka kwe-thyristor.
