Zvakadaro, crude steel production capacity ichiri pasi pezvirambidzo zvemitemo, uye muna 2008 yakakwira kusvika pakubuda pagore kwematani 660 miriyoni.Panguva ino, tsunami yemari yakakonzerwa neBritish subprime mortgage crisis yapararira pasirese.Pasi pekubatana kwehupfumi hwenyika, China iri panjodzi zvakare.Kutengeserana kune dzimwe nyika, zvinodiwa zvekudyara, zvivakwa uye zvimwe zvinhu zvakavharwa.Makambani esimbi ari pakati pemaindasitiri ekugadzira akabatwa neizvi.
Iyo simba remhando yekuongorora uye manejimendi sisitimu yekugovera simba mune metallurgical iron uye simbi indasitiri inonyanya kudzidza kubviswa kweiyo reactive simba muripo uye harmonic manejimendi matambudziko musimba rekugovera sisitimu.Zvigadzirwa zvikuru zvinosanganisira inoshanda simba sefa, yakaderera-voltage reactive simba rekubhadhara mudziyo, static var Majenareta, hybrid dynamic filter compensation devices, hybrid dynamic attenuation compensation devices, intelligent dynamic reactive power compensation devices, yakakodzera harmonic vadziviriri uye mamwe magetsi emagetsi mukuvaka kutsva. , kuvakazve, kuwedzera, uye mapurojekiti ekugadzirisa hunyanzvi mumaindasitiri, zvivakwa zveveruzhinji uye zvivakwa zveveruzhinji Reactive simba muripo, kudzvanywa kweharmonic uye manejimendi akazara, nezvimwewo, inopa mhinduro dzakakodzera dzekugadzira zvinoenderana nezvinetso zvemhando yemagetsi emhando dzakasiyana dzeindasitiri uye mhando dzemutoro, izvo zvinogona kuvandudza kunaka kwesimba rekupa uye kuve nechokwadi chekuchengetedza uye hupfumi kushanda kwesimba remagetsi.
Mitoro yakadai seDC extruders uye rectifiers inoburitsa yakawanda yeharmonic ikozvino panguva yekushanda.Kana ikasadzorwa, inokanganisa zvakanyanya kushanda kwakachengeteka kwegidhi remagetsi uye mitoro inorema mugedhi remagetsi.Uye zvakare, iyo simba chinhu chekuchinja kumhanyisa mitoro senge DC extrusion michina ichiri yakadzikira, uye reactive mutoro unochinja zvakanyanya.Iyo yechinyakare yakaderera-voltage reactive simba muripo (capacitor kabati) haigone kuiswa mune yakajairika kushanda, nekuti haigone kuramba uye kubvisa kukanganiswa kwepulse ikozvino, zvichikonzera kukanganisa kwakakomba kwemagetsi emagetsi.Kunyange kana iyo capacitor cabinet inogona kuiswa mukushanda, zvine ngozi zvikuru kupisa fuse uye kusunungura capacitor munguva pfupi.
Mushandisi Kukosha kweReactive Power Compensation uye Harmonic Control
Gadzirisa maharmonics, dzikisa harmonic ikozvino yakaunzwa musoftware software, uye funga nezvekambani yedu indasitiri zviyero;
Reactive simba rinoita muripo, simba chinhu kusvika pachiyero, kudzivirira mafaindi kubva kumakambani emagetsi;
Mushure mekugadzirisa simba rekubhadhara, simba rekushandisa ikozvino yepurogiramu yepurogiramu inoderedzwa, uye chiyero chekushandisa simba chekushandura chinowedzerwa.Kuchengetedza magetsi.
Matambudziko aungasangana nawo?
1. Iyo inotenderedza simba chinhu chechigayo chakananga ikozvino yakadzikira, kutenderera kwekushanda kupfupi, kumhanya kuri kukurumidza, uye kusarudzika kusingaite kwakakura pasi pesimba rekuita.
2. Iyo DC rolling mill haina kungoita simba shoma, asiwo inogadzira yakakwirira-yakarongeka harmonics, iyo inokanganisa kushanda kwemaitiro emagetsi emagetsi.
Mhinduro yedu:
1. Sarudza imwe-tuned sefa yekuchengetedza chiteshi cheHongyan passive sefa mudziyo dhizaini dhizaini yekusefa kunze pulse ikozvino yesoftware software uye kubhadhara reactive mutoro panguva imwe chete;
2. Adopt Hongyan simba kuchengeteka muripo mudziyo kusangana zvinodiwa kukanganisa mutoro reactive simba muripo uye harmonic kudzora.Zvinonzwisisika gadzirisa reactance rate maererano ne harmonic mamiriro ehurongwa, kubhadhara reactive simba regadziriro, uye ita kuti simba rekuita risvike pamusoro pe 0.95;
3. Shandisa Hongyan inoshingaira sefa kudzora yakakwirira-odha harmonics, uye kushandisa simba kuchengeteka muripo mudziyo kutsiva hurongwa reactive simba, uye harmonic reactive simba richasvika mureza pashure kuiswa mukushanda;
4. Shandisa Hongyan TBB ine simba isingashande yechizvarwa mudziyo kuti upe simba risingashande kune chimwe nechimwe chikamu chehurongwa, uye gadzirisa imwe neimwe harmonic yehurongwa.
