Kune nzira dzakawanda dzekudzikisa harmonic, asi hapana mhinduro yekugadzirisa matambudziko ese.Simba rakasiyana rekupa, mutoro wakasiyana, tinoda isu tinopa yakanakisa mhinduro yekudzikisa iyo harmonic.
Tafura iri pazasi inoenzanisa yeTHDi yeakasiyana harmonic mitigate matekinoroji zvisati zvaitika.
| Nhanhatu kupomba vfd hapana reactor/kukachidzwa | Nhanhatu dzakapomba vfd Yakaderera DC bhazi capacitor | Nhanhatu kupomba vfd+5% reactor/kuchika | 3 chikamu vfd inoshanda kumberi kwekupedzisira drive | Nhanhatu pulse vfd + passive sefa | Multipulse vfd | |
| Typical THDi | 90--120% | 35--40% | 35--45% | 3--5% | 5--10% | 12 pulse:10--12% 18 kupomba: 5--6% |
| Pros | Yakareruka uye yakaderera mutengo mhinduro, inogamuchirwa kumisikidzwa ine yakaderera huwandu hwemadhiraivha madiki | Yakareruka uye yakaderera mutengo mhinduro inokonzeresa kumwe kudzikisira kweazvino harmonics | Yakajairika mhinduro mumashandisirwo eHVAC | Yakanakisa harmonic kuita kweimwe yemhinduro. Kugona kuwedzera goho voltage panguva yakaderera-mutsara mamiriro. Unity fundamental power factor. Inogona kupa regenerative braking | Tichifunga kuti nzvimbo yemuviri iripo, iyo passive harmonic sefa inogona kuwedzerwa mushure mekunge drive yaiswa, kana harmonics yakatemwa kuva dambudziko. | Traditional harmonic kuderedza nzira. |
| Cons | Yakakwira harmonic yemukati, isingakurudzirwe kuisirwa neakakwira huwandu hwemadhiraivha. | Kukanganiswa kwemagetsi epamusoro, kudarika matanhatu pulse vfd ine 5% reactor/chochi. | Masisitimu ane huwandu hukuru kana hukuru hukuru hwemadhiraivha, angangoda kumwe kudzikamisa harmonic. | Iyo drive pachayo inogadzira kupisa kwakawedzera zvishoma pane yakajairwa matanhatu pulse drive ine reactor. | Inotungamira simba chinhu pamitoro yakareruka kunze kwekunge mafirita capacitor adzimwa yedunhu. Ngozi yemaresonances pakati pesefa capacitors uye mamwe macapacitor muhurongwa. | Optimal harmonic performance inoda yakanyatso dzikama AC simba rekudya nekushomeka kwemashure. Zvakaoma kwazvo kudzorera mumunda. |
Nekuenderera mberi kwekuvandudza kweIGBT tekinoroji yemagetsi, iyo nyowani-nhatu-nhanhoactive sefayakasimudzirwa zvakanyanya uye inoshandiswa mumusika.APFinowana chiratidzo chemazuva ano munguva chaiyo kuburikidza nekunze kwekushandura ikozvino, uye inoparadzanisa chikamu cheharmonic kuburikidza neyemukati yekuona dunhu, uye inogadzira muripo wezvino neinopesana nechikamu cheharmonics muhurongwa kuburikidza neIGBT inoshandura simba kuti ione basa rekusefa. kunze harmonic.
Izvo zvakabuda muripo wezvino weAPFinosiyana nemazvo zvinoenderana neiyo dynamic harmonics yehurongwa, saka hapazove nedambudziko rekuripa.Pamusoro pe,APFine overload kuchengetedza basa.Kana iyo harmonic yehurongwa yakakura kupfuura iyo sefa yehuwandu, mudziyo unogona kudzikamisa otomatiki kuburitsa kwe100% yakayerwa huwandu pasina kuwandisa.
