Abathengi abaninzi bahlala besibuza malunga nomahluko phakathi kokucoca okusebenzayo kunye ne-static var generator, ngoku mandikunike impendulo.
Isihluzi samandla asebenzayo APFluhlobo olutsha lwezixhobo zokulawula amandla e-harmonic ezenziwe ngetekhnoloji ye-elektroniki yamandla anamhlanje kunye nokusetyenzwa komqondiso wedijithali titeknoloji esekelwe kwizixhobo zeDSP ezinesantya esiphezulu.Iquka iinxalenye ezimbini eziphambili: umyalelo wesekethe yokusebenza yangoku kunye nembuyekezo yesiphaluka sesizukulwana sangoku.Umyalelo wesekethe yokusebenza yangoku ijonga okwangoku emgceni ngexesha lokwenyani, iguqula isiginali ye-analog yangoku ibe ngumqondiso wedijithali, ithumela umqondiso kwi-high-speed digital processor processor (DSP) yokucubungula, yahlula i-harmonics ukusuka kumaza asisiseko, kwaye ithumela i-drive pulse kwimbuyekezo yangoku yokuvelisa isiphaluka ngendlela ye-pulse width modulation (PWM) isignali, iqhuba i-IGBT okanye imodyuli yamandla ye-IPM.Imbuyekezo yangoku kunye ne-amplitude elinganayo kunye ne-polarity echaseneyo ye-harmonic yangoku iveliswa kwaye ifakwe kwigridi yamandla ukuhlawula okanye ukucima i-harmonic current kunye nokuphelisa ngokusebenzayo i-harmonics yamandla.
Amandla azinzileyo gumbaneyisekethe yebhulorho ezitshintshayo nge-reactor okanye iqhagamshelwe ngokuthe ngqo kwigridi yamandla, hlengahlengisa isigaba kunye ne-amplitude yecala le-AC lombane wokuphuma kwebhulorho, okanye ulawule ngokuthe ngqo icala layo le-AC langoku, ukuze isekethe ifunxe okanye ithumele ngaphandle. amandla asebenzayo okuhlangabezana neemfuno, ukufezekisa injongo yembuyekezo yamandla asebenzayo aguqukayo.
Isihluzi se-harmonic esisebenzayokunye ne-static var generator ezinye ezifanayo nezingezantsi:
1.Imilinganiselo yangaphandle ye-APF ne-SVG iyafana.Iimodyuli ezisemgangathweni zenza imveliso isebenze ngakumbi kwaye ilungelekulungele ukusebenzisa.
2.I-interface yokubeka iliso yesikrini se-APF kunye ne-SVG iyafana.
I-3.APF kunye ne-SVG zinamandlay ukubuyisela ngaxeshanye i-harmonics, amandla asebenzayo kunye nokulawula izigaba ezintathu ezingalinganiyo zangoku.
4.Isakhiwo sangaphakathi ngu-samna.
Isihluzi esisebenzayo se-harmonic kunye ne-static var umahluko wejeneretha njengezantsi:
1.Iimeko zesicelo ezahlukeneyo.I-APF isetyenziselwa ukuhluza, ngelixa i-SVG isetyenziselwa ukuhlawulela i-reactive powkwaye zisetyenziswa kwiimeko ezahlukeneyo ezineemfuno ezahlukeneyo.
2.Ukhetho kunyeiinkqubo zolawulo lwamacandelo angaphakathi zahlukile.Ngenxa yokuba imisebenzi ephambili yezi zimbini yahlukile, ijolise kwiifrikhwensi zangoku ezahlukeneyo.
3.Kukho umahluko kuluhlu lokucoca kunye nekhono.I-APF inokucoca i-2-50 ye-harmonics, ngelixa i-SVG inokuhluza kuphela i-2-13 haiimoniki.I-APF inentsebenzo engcono yokucoca, ngelixa i-SVG inokucoca kuphela i-harmonics yethu ephantsi malunga nesiqingatha somthamo wayo.
4.Kukho umahluko kwizicwangciso zeparameter.SVGIsetelwe ngokubanzi ukubuyekeza ukubaluleka kwamandla asebenzayo ngokungagqibekanga, i-APF imiselwe ngokubanzi ukubuyisela iiharmonics kuqala ngokungagqibekanga.
