Ukuhluzwa kweHarmonic kunye neMbuyekezo yaMandla asebenzayo

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.

I-SVG njengomthombo wamandla osebenzayo oguqukayo, isebenzisa amacandelo ekhompyutheni ye-high-speed efana ne-DSP / IGBT, idibene neenkqubo zokulawula ukuchaneka kwe-ultra, ukulandelela utshintsho lwexesha langempela kwigridi yangoku, kunye nokwandisa ixabiso le-PF kwi-0.99 ngaphakathi kwe-15ms.
Ukusetyenziswa okuxhaphakileyo komthamo omkhulu wemithwalo engahambelaniyo kunye nemithwalo yempembelelo efana nezixhobo zombane ze-elektroniki kwiigridi zothumelo kunye nokuhanjiswa kunye nabasebenzisi bemizi-mveliso kuzise iingxaki ezinzulu zomgangatho wamandla. I-SVG inokuphucula ngokubonakalayo umgangatho wamandla kwindawo yoqhagamshelo phakathi kwemithwalo kunye negridi yamandla kawonke-wonke, njengokuphucula into yamandla, ukoyisa ukungalingani kwezigaba ezithathu, ukuphelisa i-voltage flicker kunye nokuguquguquka kwamandla ombane, kunye nokucinezela ungcoliseko lwe-harmonic.
Isixhobo sembuyekezo samandla asebenzayo e-SVG esiveliswe yinkampani yethu sineengenelo kwisantya sokuphendula, umbane ozinzileyo wegridi, ukuncipha kwelahleko yenkqubo, ukonyuka kwamandla okuhambisa, ukuphuculwa komda wamandla ombane wethutyana, ukucutha i-harmonics, kunye nokuncipha kweenyawo. Inkampani yethu inonxibelelwano olusondeleyo lwezemfundo kunye nentsebenziswano yobugcisa kunye namaziko ophando awaziwayo kunye neenkampani zombane ekhaya nakwamanye amazwe. Sizimisele ukusebenza kunye nabathengi bethu ukuphucula umgangatho wamandla wegridi yamandla ngobuchwepheshe obuphambili kunye neemveliso ezikumgangatho ophezulu, kwaye sibe negalelo kugcino lwamandla, ukunciphisa ukusetyenziswa, kunye nemveliso ekhuselekileyo kwicandelo lokuvelisa umbane, ukubonelela kunye nosetyenziso.

Ujongene nengxaki enkulu yongcoliseko lwe-harmonic yamandla, i-AHF sesona sixhobo sisebenzayo sokuphucula umgangatho wamandla. I-AHF sisixhobo esitsha esikhethekileyo solawulo lwe-harmonic yamandla ephuhliswe kusetyenziswa itekhnoloji yale mihla yombane we-elektroniki kunye neteknoloji yokusetyenzwa kwemiqondiso yedijithali esekwe kwizixhobo ezisebenza ngesantya esiphezulu zeDSP. I-AHF ilingana nejeneretha yangoku ye-harmonic, elandelela amacandelo e-harmonic kwi-harmonic current kwaye ivelise i-harmonic currents kunye ne-amplitude elinganayo kunye nesigaba esichaseneyo. Umyalelo wesekethe yokusebenza yangoku ibona i-current in the circuit ngexesha langempela, iguqula i-analog signal yangoku ibe yisignali yedijithali, kwaye iyithumele kwi-high-speed digital processor (DSP) yokulungiswa komqondiso. I-harmonic kunye ne-principal currents zihlukaniswe ukuze zifumane i-current instruction, ethi ke ithunyelwe kwimbuyekezo yesizukulwana sangoku sesiphaluka ngendlela ye-pulse wide modulation (PWM) isignali ngokusebenzisa isiphaluka solawulo lokulandelela umkhondo kunye nesekethe yokuqhuba. Iimodyuli zamandla e-IGBT kunye ne-IPM ziqhutyelwa ukuvelisa imbuyekezo yangoku kunye ne-amplitude efanayo kunye ne-polarity echaseneyo njenge-harmonic current, efakwe kwigridi yamandla ukuhlawula okanye ukukhansela i-harmonic current, ukuphelisa ngokusebenzayo i-harmonics yamandla, kunye nokufezekisa ukuqhutyelwa kwe-dynamics, ngokukhawuleza, kunye nokucokisekileyo kwe-harmonics yamandla.
