Amakhasimende amaningi ngokwengeziwe ngokuvamile asibuza mayelana nomehluko phakathi kwesihlungi se-harmonic esisebenzayo kanye ne-static var generator, manje ake ngikunikeze impendulo.
Isihlungi samandla asebenzayo i-APFuhlobo olusha lwemishini yokulawula i-harmonic eyenziwe ngobuchwepheshe besimanje bamandla kagesi kanye nokucubungula isignali yedijithali tubuchwepheshe obusekelwe kumadivayisi e-DSP anesivinini esikhulu.Iqukethe izingxenye ezimbili eziyinhloko: umyalo wesifunda sokusebenza kwamanje kanye nesifunda sesinxephezelo sesizukulwane samanje.Umyalo wesekethe yokusebenza yamanje uqapha okwamanje kulayini ngesikhathi sangempela, uguqule isignali yamanje ye-analog ibe isignali yedijithali, ithumele isignali kuphrosesa yesignali yedijithali enesivinini esikhulu (DSP) ukuze icutshungulwe, ihlukanise ama-harmonics kumagagasi ayisisekelo, futhi ithumela ukushaya kwedrayivu kusekethe ekhiqizayo yamanje yesinxephezelo ngendlela yesignali ye-pulse wide modulation (PWM), ishayela imojula yamandla ye-IGBT noma ye-IPM.Imanje esinxephezelayo esinobude obulinganayo kanye ne-polarity ephambene ye-harmonic current iyakhiqizwa futhi ifakwe kugridi yamandla ukuze kunxeshezelwe noma kukhanselwe i-harmonic current futhi kuqedwe ngenkuthalo ama-harmonics wamandla.
Amandla asebenzayo amile gi-eneratoriyisekhethi yebhuloho elizishintshayo nge-reactor noma exhunywe ngokuqondile kugridi yamandla, lungisa isigaba kanye nobukhulu bohlangothi lwe-AC lwevolthi yokuphuma kwesekethe yebhuloho, noma ilawule ngokuqondile uhlangothi lwayo lwamanje lwe-AC, ukuze isekethe imunce noma ithumele ngaphandle. amandla asebenzayo okuhlangabezana nezidingo, ukufeza inhloso yesinxephezelo samandla asebenzayo aguqukayo.
Isihlungi se-harmonic esisebenzayokanye ne-static var generator efanayo naleyo engezansi:
1.Ubukhulu bangaphandle be-APF ne-SVG buyafana.Amamojula ajwayelekile enza ukukhiqiza kusebenze kahle futhi kuhambisanekulula ukuyisebenzisa.
2.Isixhumi esibonakalayo sesikrini sokuthinta sokuqapha se-APF ne-SVG siyefana.
3.APF kanye ne-SVG banekhonoy ukunxephezela kanyekanye ama-harmonics, amandla asebenzayo kanye nokulawula izigaba ezintathu ezingalingani zamanje.
4.Isakhiwo sangaphakathi yi-samina.
Isihlungi esisebenzayo se-harmonic ne-static var generator umehluko njengoba ngezansi:
1.Izimo zokusebenza ezihlukene.I-APF isetshenziselwa ukuhlunga, kuyilapho i-SVG isetshenziselwa kakhulu ukunxephezela amandla asebenzayoer futhi zisetshenziswa ezimeni ezahlukene ezinezidingo ezahlukene.
2.Ukukhethwa kanyeizinqubo zokulawula zezingxenye zangaphakathi zihlukile.Ngenxa yokuthi imisebenzi esemqoka yakho kokubili ihlukile, iqondise amaza amanje ahlukene.
3.Kunomehluko ebangeni lokuhlunga kanye nekhono.I-APF ingahlunga ama-harmonics angu-2-50, kuyilapho i-SVG ingakwazi ukuhlunga kuphela ama-2-13 haama-monics.I-APF inokuhlunga okungcono kakhulu, kuyilapho i-SVG ingahlunga kuphela ama-harmonics ethu aphansi cishe cishe ingxenye yomthamo wayo.
4.Kunomehluko kuzilungiselelo zepharamitha.I-SVGngokuvamile isethelwe ukunxephezela ukubaluleka kwamandla asebenzayo ngokuzenzakalelayo, i-APF ngokuvamile isethelwe ukunxephezela okuvumelanayo kuqala ngokuzenzakalelayo.
