Komabe, mphamvu yaku China yopanga zitsulo zosapanganika ikadali yoletsedwa ndi malamulo, ndipo mu 2008 idakwera mpaka matani 660 miliyoni pachaka.Panthawiyi, tsunami yazachuma yomwe idayambitsidwa ndi vuto la kubwereketsa nyumba yaku Britain subprime yafalikira padziko lonse lapansi.Pansi pa kuphatikiza kwachuma padziko lonse lapansi, China ilinso pachiwopsezo.Malonda akunja, zofunikira zandalama, malo ndi zina zaletsedwa.Makampani azitsulo ali m'gulu la mafakitale opanga zomwe zakhudzidwa ndi izi.
Kusanthula kwamphamvu kwamphamvu ndi kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake.Zogulitsa zazikuluzikulu zikuphatikizapo fyuluta yamagetsi yogwira ntchito, chipangizo chochepetsera mphamvu chochepa chamagetsi, static var Generators, hybrid dynamic filter compensation devices, hybrid dynamic attenuation compensation zipangizo, zida zanzeru zogwiritsira ntchito mphamvu zowonongeka, zoyenera zotetezera harmonic ndi zipangizo zina zamagetsi mu zomangamanga zatsopano. , kumanganso, kukulitsa, ndi ntchito yokonza luso m'mafakitale, wamba ndi nyumba za anthu Zowonongeka mphamvu chipukuta misozi, harmonic kuponderezedwa ndi kasamalidwe mabuku, etc., kupereka mayankho oyenerera kapangidwe malinga ndi mphamvu khalidwe mavuto a mitundu yosiyanasiyana makampani ndi katundu mitundu, amene angathe kusintha ubwino wa magetsi ndikuonetsetsa kuti magetsi akuyenda bwino komanso achuma.
Katundu monga DC extruder ndi rectifiers kutulutsa kuchuluka kwa harmonic panopa pa ntchito.Ngati sichiwongoleredwa, chidzakhudza kwambiri ntchito yotetezeka ya gridi yamagetsi ndi katundu wovuta mu gridi yamagetsi.Kuonjezera apo, mphamvu yamagetsi othamanga osinthika monga makina a DC extrusion akadali otsika kwambiri, ndipo katundu wothamanga amasinthasintha kwambiri.Kulipiritsa kwamphamvu kwamagetsi otsika kwambiri (capacitor cabinet) sikungagwire ntchito bwino, chifukwa sikungathe kukana ndikuchotsa kugunda kwamphamvu, zomwe zimapangitsa kuwononga kwambiri mphamvu zamagetsi.Ngakhale kabati ya capacitor ingagwiritsidwe ntchito, ndizoopsa kwambiri kuwotcha fuse ndikutulutsa capacitor mu nthawi yochepa.
Kufunika kwa Wogwiritsa Ntchito Kulipiridwa Kwa Mphamvu Zowonongeka ndi Kuwongolera kwa Harmonic
Konzani ma harmonics, kuchepetsa mphamvu ya ma harmonic yomwe imalowetsedwa mu pulogalamu yamakina, ndikuganiziranso zamakampani athu;
Kulipiritsa kwamphamvu kwamphamvu, mphamvu yamagetsi mpaka muyezo, kupewa chindapusa kuchokera kumakampani opanga magetsi;
Pambuyo pakubwezeredwa kwamphamvu kwamagetsi, mphamvu yamagetsi yamagetsi yamagetsi imachepetsedwa, ndipo mphamvu yogwiritsira ntchito thiransifoma ikuwonjezeka.Kupulumutsa mphamvu.
Mavuto omwe mungakumane nawo?
1. Mphamvu yogubuduza ya mphero yachindunji ndi yotsika kwambiri, kayendetsedwe kake kakugwira ntchito ndi kakang'ono, liwiro limakhala lofulumira, ndipo kusinthasintha kosavomerezeka ndi kwakukulu pansi pa katundu wokhudzidwa.
2. Mphero yopukutira ya DC sikuti imakhala ndi mphamvu yochepa chabe, komanso imapanga ma harmonics apamwamba, omwe amakhudza ntchito yachibadwa ya zipangizo zamagetsi.
Yankho lathu:
1. Sankhani njira imodzi yokha yotetezera fyuluta ya Hongyan passive fyuluta kamangidwe kachipangizo kuti muzisefa kugunda kwamakono kwa pulogalamu yamakono ndikubwezera katundu wotakataka nthawi imodzi;
2. Kutengera Hongyan mphamvu chitetezo chipukuta misozi chipangizo kukwaniritsa zofunika katundu zotakasika mphamvu chipukuta misozi ndi kulamulira harmonic.Konzani momveka bwino kuchuluka kwa ma reactance molingana ndi momwe ma harmonic amagwirira ntchito, lipirani mphamvu yokhazikika yadongosolo, ndikupangitsa kuti mphamvuyo ifike pamwamba pa 0,95;
3. Gwiritsani Hongyan yogwira fyuluta kulamulira ma harmonics mkulu-kuti, ndi ntchito zazikulu chitetezo chipukuta misozi chipangizo kubwezera dongosolo zotakasika mphamvu, ndi harmonic zotakasika mphamvu adzafika muyezo pambuyo kuika mu ntchito;
4. Gwiritsani ntchito Hongyan TBB zosinthika zosagwira ntchito m'badwo chipangizo kupereka mphamvu chopanda mphamvu gawo lililonse la dongosolo, ndi kusamalira harmonic aliyense wa dongosolo.
