Kusiyana pakati pa sefa yogwira ya harmonic ndi static var jenereta

Makasitomala ochulukirachulukira nthawi zambiri amatifunsa za kusiyana pakati pa zosefera za harmonic ndi static var jenereta, tsopano ndikupatseni yankho.

Active mphamvu fyuluta APFndi mtundu watsopano wa zida zowongolera zamagetsi zomwe zimapangidwa ndiukadaulo wamakono wamagetsi amagetsi ndi makina a digito tukadaulo wozikidwa pazida zothamanga kwambiri za DSP.Lili ndi magawo awiri akulu: kulamula mayendedwe apano komanso chipukuta misozi cham'badwo wamakono.Lamulo lomwe likugwira ntchito pano limayang'anira zomwe zikuchitika pamzere mu nthawi yeniyeni, kutembenuza chizindikiro cha analogi kukhala chizindikiro cha digito, kutumiza chizindikirocho ku purosesa yothamanga kwambiri ya digito (DSP) kuti ikonzedwe, imalekanitsa ma harmonics ku mafunde ofunikira, ndi imatumiza kugunda kwagalimoto kudera lomwe likupanga chipukuta misozi ngati chizindikiro cha pulse wide modulation (PWM), imayendetsa gawo lamphamvu la IGBT kapena IPM.Mphamvu yolipirira yomwe ili ndi matalikidwe ofanana ndi polarity yosiyana ya ma harmonic panopa imapangidwa ndikubayidwa mu gululi yamagetsi kuti alipire kapena kuletsa ma harmonic panopa ndikuchotsa mwachangu ma harmonics amphamvu.

Static zotakataka mphamvu gmpweyandi dera lodziyendetsa la mlatho kudzera pa riyakitala kapena lolumikizidwa mwachindunji ndi gridi yamagetsi, sinthani gawo ndi matalikidwe a mbali ya AC ya voteji yamagetsi amagetsi, kapena kuwongolera mwachindunji mbali yake ya AC, kuti dera litenge kapena kutumiza kunja. mphamvu yogwira ntchito kuti ikwaniritse zofunikira, kukwaniritsa cholinga cha chipukuta misozi champhamvu.

Chosefera chogwira ntchitondi static var jenereta zina zofananira pansipa:

1.Miyeso yakunja ya APF ndi SVG ndi yofanana.Ma module okhazikika amapangitsa kupanga kukhala kothandiza komanso kosavutakuzigwiritsa ntchito.

2.The polojekiti kukhudza chophimba mawonekedwe a APF ndi SVG ndi chimodzimodzi.
3.APF ndi SVG ali ndi kuthekeray kubwezera nthawi imodzi ma harmonics, mphamvu yogwira ntchito ndikuwongolera magawo atatu osagwirizana pano.

4.Mapangidwe amkati ndi saine.

Zosefera za harmonic ndi static var jenereta kusiyana monga pansipa:

1.Zigawo zosiyana zogwiritsira ntchito.APF imagwiritsidwa ntchito kwambiri posefa, pomwe SVG imagwiritsidwa ntchito makamaka polipira mphamvu yogwira ntchitoer ndipo amagwiritsidwa ntchito muzochitika zosiyanasiyana ndi zofunikira zosiyanasiyana.

2.Kusankhidwa ndinjira zowongolera za zigawo zamkati ndizosiyana.Chifukwa ntchito zazikuluzikulu za ziwirizi ndizosiyana, zimatsata ma frequency osiyanasiyana.

3.Pali kusiyana kwa zosefera ndi kuthekera.APF imatha kusefa ma 2-50 ma harmonics, pomwe SVG imatha kusefa 2-13 hama monics.APF imachita bwino kusefa, pomwe SVG imatha kusefa ma harmonics athu otsika ndi pafupifupi theka la mphamvu zake.

4.Pali kusiyana kwa magawo a parameter.SVGnthawi zambiri imayikidwa kuti ipereke chiwongola dzanja champhamvu chokhazikika mwachisawawa, APF nthawi zambiri imayikidwa kuti ibwezere ma harmonics poyamba mwachisawawa.
