Nangona kunjalo, amandla emveliso yentsimbi ekrwada yaseTshayina isaxhomekeke kwimiqathango yomgaqo-nkqubo, kwaye ngo-2008 inyuke yaya kutsho kwiitoni ezizizigidi ezingama-660 ngonyaka.Ngeli xesha, i-tsunami yezemali ebangelwa yi-British subprime mortgage crisis iye yasasazeka kwihlabathi.Ngaphantsi kokudityaniswa koqoqosho lwehlabathi, iChina nayo isengozini.Urhwebo lwangaphandle, iimfuno zotyalo-mali, umhlaba kunye neminye imiba ivaliwe.Iinkampani zentsimbi ziphakathi kwemizi-mveliso yemveliso echatshazelwa koku.
Uhlalutyo lomgangatho wamandla kunye nenkqubo yolawulo lwenkqubo yokuhanjiswa kwamandla kwi-metallurgical iron and steel industry ikakhulu ifunda ukupheliswa kwembuyekezo yamandla asebenzayo kunye neengxaki zolawulo lwe-harmonic kwinkqubo yokuhanjiswa kwamandla.Iimveliso eziphambili zibandakanya isihluzo samandla asebenzayo, isixhobo sembuyekezo yamandla aphantsi-voltage esebenzayo, i-static var Generators, izixhobo zembuyekezo ye-hybrid dynamic filter, izixhobo zembuyekezo ze-hybrid dynamic attenuation, izixhobo ezikrelekrele eziguqukayo zembuyekezo zamandla, ezifanelekileyo kubakhuseli be-harmonic kunye nezinye izixhobo zombane kulwakhiwo olutsha. , ukwakhiwa ngokutsha, ukwandiswa, kunye neeprojekthi zohlaziyo lobuchwephesha kwimizi-mveliso, izakhiwo zokuhlala kunye nezakhiwo zikawonke-wonke Imbuyekezo yamandla asebenzayo, ukucinezelwa kwe-harmonic kunye nolawulo olubanzi, njl. njl., ukunika izisombululo zoyilo ezifanelekileyo ngokweengxaki zomgangatho wamandla weentlobo ezahlukeneyo zeshishini kunye neentlobo zomthwalo, ezinokuphucula umgangatho wonikezelo lwamandla kunye nokuqinisekisa ukusebenza ngokukhuselekileyo kunye noqoqosho lwenkqubo yamandla.
Imithwalo efana ne-DC extruders kunye ne-rectifiers ivelisa isixa esikhulu se-harmonic yangoku ngexesha lokusebenza.Ukuba ayilawulwa, iya kuchaphazela kakhulu ukusebenza okukhuselekileyo kwegridi yamandla kunye nemithwalo ebuthathaka kwigridi yamandla.Ukongeza, umba wamandla wemithwalo yesantya eguquguqukayo efana noomatshini be-DC extrusion isephantsi kakhulu, kwaye umthwalo osebenzayo uguquguquka ngakumbi.Imbuyekezo yamandla asebenzayo asezantsi-voltage (ikhabhinethi ye-capacitor) ayinakufakwa ekusebenzeni okuqhelekileyo, kuba ayinakuxhathisa kwaye isuse impembelelo ye-pulse yangoku, okukhokelela kwinkcitho enkulu yamandla ombane.Nangona ikhabhinethi ye-capacitor inokufakwa ekusebenzeni, kuyingozi kakhulu ukutshisa i-fuse kunye nokukhupha i-capacitor ngexesha elifutshane.
Ixabiso lomsebenzisi weMbuyekezo yaMandla asebenzayo kunye noLawulo lweHarmonic
Lungisa i-harmonics, unciphise i-harmonic yangoku engeniswe kwisoftware yenkqubo, kwaye uqwalasele imigangatho yoshishino yenkampani yethu;
Imbuyekezo yamandla asebenzayo, umba wamandla ukuya kumgangatho, ukuthintela izohlwayo ezivela kwiinkampani zobonelelo ngombane;
Emva kwembuyekezo yamandla asebenzayo, umbane wangoku we-software yenkqubo uyancitshiswa, kwaye izinga lokusetyenziswa kwamandla kwe-transformer liyenyuka.Ukonga amandla.
Iingxaki onokudibana nazo?
1. Umbane wokuqengqeleka wesixhobo sokusila sangoku sisezantsi kakhulu, umjikelo wokusebenza umfutshane, isantya sikhawuleza, kwaye ukuguquguquka okungavumelekanga kukhulu phantsi komthwalo wempembelelo.
2. I-DC rolling mill ayinayo kuphela amandla aphantsi, kodwa iphinda ivelise i-harmonics ephezulu, echaphazela ukusebenza okuqhelekileyo kwezixhobo zombane.
Isisombululo sethu:
1. Khetha umjelo wokhuseleko wokucoca ulwelo olunye lwecebo loyilo lwesixhobo sokucoca ukucoca ulwelo lokucoca ulwelo lwangoku lwenkqubo yesoftware kwaye ubuyekeze umthwalo osebenzayo ngaxeshanye;
2. Yamkela isixhobo sembuyekezo yokhuseleko oluguqukayo lweHongyan ukuhlangabezana neemfuno zomthwalo wempembelelo yembuyekezo yamandla asebenzayo kunye nolawulo lwe-harmonic.Ukuqwalasela ngokufanelekileyo izinga lokuphendula ngokwemiqathango ye-harmonic yenkqubo, ubuyekeze amandla asebenzayo enkqubo, kwaye wenze ukuba amandla ombane afikelele ngaphezu kwe-0.95;
3. Sebenzisa i-Hongyan filter esebenzayo ukulawula i-harmonics ephezulu, kwaye usebenzise isixhobo sembuyekezo yokhuseleko oluguqukayo ukubuyisela amandla asebenzayo enkqubo, kwaye amandla asebenzayo e-harmonic aya kufikelela kumgangatho emva kokufakwa ekusebenzeni;
4. Sebenzisa i-Hongyan TBB isixhobo sokuvelisa esingasebenziyo ukunika amandla angasebenziyo kwinqanaba ngalinye lenkqubo, kwaye ulawule i-harmonic nganye yenkqubo.
