Ukuhlunga kwe-Harmonic kanye Nesinxephezelo Samandla Asebenzayo

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.

I-SVG njengomthombo wamandla asebenzayo ashukumisayo, isebenzisa izingxenye zekhompuyutha ezinesivinini esikhulu njenge-DSP/IGBT, ehlanganiswe nezinhlelo zokulawula ukunemba okukhulu, ukulandelela izinguquko zesikhathi sangempela kugridi yamanje, nokwandisa inani le-PF libe ngu-0.99 phakathi kuka-15ms.
Ukusetshenziswa okusabalele komthamo omkhulu wemithwalo engaqondile kanye nemithwalo eshukumisayo efana nemishini kagesi kagesi kumagridi okudlulisa nokusabalalisa kanye nabasebenzisi bezimboni kulethe izinkinga ezinkulu zekhwalithi yamandla. I-SVG ingathuthukisa kakhulu ikhwalithi yamandla endaweni yokuxhuma phakathi kwemithwalo negridi yamandla omphakathi, njengokuthuthukisa isici samandla, ukunqoba ukungalingani kwezigaba ezintathu, ukuqeda ukucwayiza kwamandla kagesi kanye nokushintshashintsha kwamandla kagesi, nokucindezela ukungcoliswa kwe-harmonic.
Idivayisi yesinxephezelo samandla asebenzayo e-SVG ekhiqizwa inkampani yethu inezinzuzo ngesivinini sokuphendula, ugesi wegridi ozinzile, ukuncipha kokulahlekelwa kwesistimu, ukukhuphuka kwamandla okudlulisela, ukuthuthukiswa komkhawulo wamandla kagesi wesikhashana, ukuncishiswa kwama-harmonics, kanye nokuncishiswa kwezinyathelo. Inkampani yethu inokuxhumana okuseduze kwezemfundo nokubambisana kwezobuchwepheshe nezikhungo zocwaningo ezaziwayo nezinkampani zikagesi ekhaya naphesheya. Sizimisele ukusebenzisana namakhasimende ethu ukuze sithuthukise izinga lamandla egridi kagesi ngobuchwepheshe obuthuthukisiwe nemikhiqizo eseqophelweni eliphezulu, futhi sibambe iqhaza ekongiweni kukagesi, ekunciphiseni ukusetshenziswa, kanye nokukhiqizwa okuphephile emikhakheni yokuphehla ugesi, ukuhlinzeka, kanye nokusetshenziswa kwamandla.

Ibhekene nenkinga enzima yokungcoliswa kwe-harmonic yamandla, i-AHF iyithuluzi elisebenza kahle kakhulu lokuthuthukisa ikhwalithi yamandla. I-AHF iyisisetshenziswa esisha esikhethekile sokulawula i-harmonic yamandla esakhiwe kusetshenziswa ubuchwepheshe besimanje bamandla kagesi kanye nobuchwepheshe bokucubungula amasignali edijithali okusekelwe kumadivayisi okucubungula e-DSP anesivinini esikhulu. I-AHF ilingana nejeneretha yamanje ye-harmonic, elandelela izingxenye ze-harmonic ku-harmonic current futhi ikhiqize ama-harmonic currents nge-amplitude elinganayo nesigaba esiphambene.I-AHF iqukethe izingxenye ezimbili: umjikelezo wokusebenza kwamanje kanye nesifunda sesinxephezelo sesizukulwane samanje. Umjikelezo wokusebenza kwamanje weziyalezo uhlonza i-current in circuit ngesikhathi sangempela, uguqule isignali yamanje ye-analog ibe isignali yedijithali, futhi iyithumele kuphrosesa yedijithali enesivinini esikhulu (i-DSP) ukuze kucutshungulwe isignali. Ama-harmonic kanye nama-basic currents ahlukaniswa ukuze kutholwe isifundiso samanje, esibe sesithunyelwa kumjikelezo wesizukulwane samanje sesinxephezelo ngendlela yesignali ye-pulse wide modulation (PWM) ngokusebenzisa isifunda sokulawula ukulandelwa kwamanje kanye nesekethe yedrayivu. Amamojula wamandla e-IGBT kanye ne-IPM aqhutshwa ukuze akhiqize amandla amanje esinxephezelo ane-amplitude efanayo ne-polarity ephambene ne-harmonic current, efakwa kugridi yamandla ukuze kunxeshezelwe noma kukhanselwe i-harmonic yamanje, ukuqeda ngenkuthalo ukuhambisana kwamandla, futhi kuzuzwe ukucubungula okuguquguqukayo, okusheshayo, nokuphelele kokuvumelana kwamandla.
