Isithando somlilo sekristale esisodwa luhlobo lwezixhobo ezisebenzisa i-heater yegraphite ecocekileyo ukunyibilikisa izinto eziluhlaza ze-polycrystalline ezifana neeseli ze-photovoltaic kwindawo enqabileyo yegesi, kwaye isebenzisa indlela ye-Czochralski ukukhulisa i-crystal eyodwa engena-dislocation.Iziko elinye lekristale lisetyenziswa ngokuqhelekileyo.Iimveliso ezininzi ezifana ne-silicon ye-monocrystalline, i-monocrystalline germanium, kunye ne-monocrystalline gallium arsenide zizinto ezibalulekileyo ezibonakalayo kwishishini le-electronics kunye namanye amashishini aphezulu.Ngokukhula okuqhubekayo kophuhliso loqoqosho lwelizwe lam, ukusetyenziswa kweziko lekristale enye kuya kuba banzi.
Njengenye yamasebe abalulekileyo eziko zoshishino, iziko lekristale enye idla amandla amaninzi.Iindleko eziphezulu zombane kunye nongcoliseko oluphezulu lwe-harmonic lukhokelela ekuthotyweni komgangatho wemveliso, oye waba yintliziyo ebuhlungu kubasebenzisi abaninzi be-crystal eyodwa.Ukuphendula kwiimfuno ezingxamisekileyo zokukhuselwa kwendalo kunye nokonga amandla kubathengi abaninzi beziko le-polysilicon kwihlabathi liphela, abaninzi abavelisi benze imizamo kunye nemizamo elungileyo.Abantu abaninzi bazama ukukhusela inkqubo kwi-transients, i-surges kunye neemveliso zokunciphisa i-harmonic ukwenza iiprojekthi zokuguqulwa kwezobuchwepheshe kwinkqubo yesithando somlilo se-polysilicon, kodwa usetyenziso lwangempela lubonisa ukuba i-harmonic frequencies of the polysilicon furnace ubukhulu becala yi-5th, 7th kunye ne-11. Ubuninzi bomthamo wamanzi we-sub-harmonic budlula i-45%, i-7th harmonic 20%, i-11 ye-harmonic 11%, izinga lokulahlekelwa kwesakhelo lilonke lidlula i-49.43%, umbane omncinci we-0.4570 kuphela, kunye nowona mandla aphezulu ngu-0.6464 kuphela. ).Ngoko ke, indlela yokulawula i-pulse yangoku yezi zixhobo ayinakuhoywa, kwaye umphumo wokonga amandla awunelisi.Eyona nto imbi kakhulu kukuba amandla akhoyo e-pulse agqithisa kakhulu kuluhlu lwezixhobo zombane, kwaye kulula ukonakalisa emva kokusetyenziswa kwexesha elide.Iziganeko eziphezulu zeengozi zichaphazela ukusebenza okuqhelekileyo kwemveliso yenkampani, okubangela inkcitho yemithombo kunye noxinzelelo lwabathengi.
Iseti yezixhobo zembuyekezo yokucoca eyenzelwe mna ngolu hlobo lwezixhobo zinokucombulula ngempumelelo ezi ngxaki zingentla (iindlela ezimbini: ukuba zombini ulawulo lwe-harmonic kunye nembuyekezo yamandla asebenzayo kufuneka ukuba udlule umgangatho, sisebenzisa i-harmonic control loop + i-reactive power adjustment Loop; ukusebenza okuqhelekileyo kufuna kuphela imbuyekezo yamandla asebenzayo, kwaye umba wamandla ugqitha ummiselo.Ayinakulawula kuphela i-harmonics, kodwa iphinde ihlawule imithwalo esebenzayo.Inokuphelisa ngokupheleleyo ungcoliseko lwendalo esingqongileyo kunye nokuphucula amandla.Inzuzo ebalulekileyo yezoqoqosho.Iindleko zokusebenza zinokufunyanwa kwakhona kwisithuba seenyanga ezi-3 ukuya kwezi-5.
eyona nto ibalulekileyo:
1. Kwinkqubo yesoftware yabathengi *, i-harmonics yeempawu ezicacileyo, ezinje: 5th, 7th, 11th, 13th, njl. Isiphumo sokucoca siyabonakala.
2. I-Harmonics inokulawulwa, imbuyekezo ayisebenzi
3. Emva kokuba isixhobo sokucoca sisetyenzisiwe, sinokuphucula kakhulu umgangatho wamandla, siphucule impembelelo yangoku ebangelwa ngumthwalo wempembelelo, ukunciphisa ukuguquguquka kwamandla ombane, ukucinezela i-flicker yamandla ombane, ukuphucula ukuthembeka kwamandla ombane, kunye nokuphucula umgangatho wombane.Umbane wamandla unokunyuswa ngaphezu kwe-0.96, kwaye ukunciphisa ukulahleka komgca womsebenzisi kunokuphucula ukusebenza kakuhle kwe-transformer yokusabalalisa, kwaye inzuzo yezoqoqosho iyabonakala.
4. Izitshixo ze-vacuum zokusebenza zisetyenziselwa ukutshintshela i-loop yesihluzi ngasinye.Inkqubo yokulawula ngokuzenzekelayo icacisiwe kwaye imisebenzi yokugcinwa igqibelele, njengokukhuselwa kwangoku, ukukhuselwa kwe-voltage, ukukhuselwa kwangoku, njl. Umsebenzi wangempela unokwethenjelwa kwaye umsebenzi ulula.
Izinto eziluncedo kuLawulo lweHarmonic:
1. Emva kokufaka izixhobo zokulawula i-pulse yangoku, i-harmonic current ingancitshiswa ngokufanelekileyo, umthamo ofanelekileyo we-transformer unokunyuswa, umthamo ohambelanayo wokuthwala ikhebula nawo unyuswe, kwaye utyalo-mali lweprojekthi olufunekayo ekwandiseni luyancitshiswa.
2. Emva kokufaka izixhobo zokulawula i-pulse yangoku, ukulahlekelwa kwe-transformer kunokunciphisa ngokufanelekileyo, isalathisi sokusebenza ngokukhuselekileyo se-transformer sinokuphuculwa, kwaye injongo yokonga amandla kunye nokunciphisa ukukhutshwa kunokufezekiswa.
Izisombululo onokukhetha kuzo:
isicwangciso 1
Kulawulo oluphakathi (elufaneleke kwiziko ezininzi ezabelana nge-transformer enye kwaye zisebenze ngaxeshanye, igumbi lokuhambisa amandla lixhotyiswe ngesixhobo sembuyekezo yokucoca)
1. Sebenzisa isebe lolawulo lwe-harmonic (5, 7, 11 filter) + isebe lolawulo lwamandla asebenzayo.Emva kokuba isixhobo sembuyekezo yesihluzi sifakwe ekusebenzeni, ulawulo lweharmonic kunye nembuyekezo yamandla asebenzayo wenkqubo yonikezelo lwamandla ihlangabezana neemfuno.
2. Yamkela isihluzi esisebenzayo (susa ucwangco lwe-harmonics eguquguqukayo) kunye ne-harmonic countermeasure yesekethe yesebe (5, 7, 11 icebo lokucoca) # + uhlengahlengiso olungasebenziyo lwesekethe yesebe, kwaye emva kokubonelela kwisixhobo sembuyekezo yesihluzo, beka phambili Isicelo sembuyekezo engasebenziyo inkqubo yonikezelo lwamandla.
3. Sebenzisa izixhobo zembuyekezo ezingasebenziyo (5.5%, 6% reactors) ukucinezela i-harmonics, kwaye emva kokubeka izixhobo zembuyekezo zokucoca, zifuna inkqubo yonikezelo lwamandla ukwenza imbuyekezo engasebenziyo.
Imeko yesi-2
Ulawulo olukwisiza (seta ipaneli yembuyekezo yokucoca ecaleni kwephaneli yonikezelo lwamandla lwe-monocrystalline silicon eziko)
1. Isebe lokulawula i-Harmonic (5, 7, 11 filtering) yamkelwa, kwaye amandla asebenzayo e-harmonic afikelela kumgangatho emva kokufakwayo.
2. Khetha i-reactor yokukhusela kunye ne-filter i-double-loop power supply (i-5th kunye ne-7th filter) ukuze ugweme impembelelo efanayo, kwaye i-pulse yangoku emva kokudibanisa ayidluli inkcazo.
