Ng'anjo imodzi ya kristalo ndi mtundu wa zipangizo zomwe zimagwiritsa ntchito chotenthetsera choyera kwambiri cha graphite kusungunula zipangizo za polycrystalline monga maselo a photovoltaic m'malo osowa mpweya, ndipo amagwiritsa ntchito njira ya Czochralski kuti ikule kristalo imodzi yopanda kusuntha.Ng'anjo za kristalo imodzi zimagwiritsidwa ntchito kwambiri.Zogulitsa zambiri monga silicon ya monocrystalline, monocrystalline germanium, ndi monocrystalline gallium arsenide ndizofunikira kwambiri pamakampani opanga zamagetsi ndi mafakitale ena apamwamba kwambiri.Ndi kukula kosalekeza kwa chitukuko cha chuma cha dziko langa, kugwiritsa ntchito ng'anjo imodzi ya kristalo kudzawonjezereka.
Monga imodzi mwa nthambi zofunika za ng'anjo za mafakitale, ng'anjo za kristalo imodzi zimawononga mphamvu zambiri.Mtengo wapamwamba wamagetsi ndi kuipitsidwa kwakukulu kwa harmonic kumabweretsa kuwonongeka kwa khalidwe la mankhwala, zomwe zakhala zowawa kwambiri kwa ogwiritsa ntchito ng'anjo ya crystal imodzi.Poyankha zofunikira zachangu zoteteza chilengedwe ndi kupulumutsa mphamvu kwa makasitomala ambiri ang'anjo ya polysilicon padziko lonse lapansi, opanga ambiri ayesetsa kuchita bwino komanso kuyesa.Anthu ambiri amayesa kuteteza dongosolo ku transients, surges ndi mankhwala harmonic kupondereza kuchita ntchito zamakono kusintha pa dongosolo polysilicon ng'anjo, koma ntchito yeniyeni limasonyeza kuti mafunde a harmonic a polysilicon ng'anjo makamaka 5, 7 ndi 11 harmonics (5) Madzi ochuluka a subharmonic amaposa 45%, 7th harmonic 20%, 11th harmonic 11%, chiwerengero cha kutaya kwa chimango chimaposa 49.43%, mphamvu yocheperako ndi 0.4570 yokha, ndipo mphamvu yaikulu ndi 0.6464 yokha ).Choncho, njira yoyendetsera pulse panopa ya zipangizozi sizinganyalanyazidwe, ndipo mphamvu zopulumutsa mphamvu sizokhutiritsa.Choyipa kwambiri ndi chakuti mphamvu ya pulse panopa imaposa zida zamagetsi zonyamula katundu, ndipo ndizosavuta kuwononga pambuyo pozigwiritsa ntchito nthawi yayitali.Kuchuluka kwa ngozi kumakhudza momwe kampaniyo imagwirira ntchito, zomwe zimapangitsa kuti zinthu ziwonongeke komanso kuvutika kwamakasitomala.
Seti ya zida zolipirira zosefera zomwe ndidapanga zida zamtunduwu zimatha kuthana bwino ndi mavuto omwe ali pamwambawa (njira ziwiri: ngati zonse zowongolera za harmonic ndi kubwezeredwa kwa mphamvu zogwira ntchito zimafunikira kupitilira muyezo, timagwiritsa ntchito harmonic control loop + reactive power adjustment Loop; ntchito yachibadwa imangofunika kubwezeredwa kwa mphamvu yamagetsi, ndipo mphamvu yamagetsi imaposa momwe zimakhalira.Sizingangowongolera ma harmonics, komanso kubweza katundu wotakataka.Ikhoza kuthetsa kuipitsidwa kwa chilengedwe ndi harmonic ndikuwongolera mphamvu.Zopindulitsa zazikulu zachuma.Ndalama zogwirira ntchito zimatha kubwezeredwa mkati mwa miyezi 3 mpaka 5.
mbali yayikulu:
1. Pulogalamu yamakasitomala *, mawonekedwe omveka bwino, monga: 5, 7, 11, 13, etc. Zosefera ndizodziwikiratu.
2. Ma Harmonics amatha kuyang'aniridwa, chipukuta misozi sichigwira ntchito
3. Chida chosefera chikayamba kugwira ntchito, chimatha kuwongolera mphamvu yamagetsi, kuwongolera zomwe zikuchitika chifukwa cha kuchuluka kwa mphamvu, kuchepetsa kusinthasintha kwamagetsi, kupondereza kuphulika kwamagetsi, kuwongolera kudalirika kwamagetsi, ndikuwongolera mtundu wamagetsi.Mphamvu yamagetsi imatha kukulitsidwa kupitilira 0.96, ndipo kuchepetsedwa kwa kutayika kwa mzere wa ogwiritsa ntchito kumatha kupititsa patsogolo kunyamula bwino kwa chosinthira chogawa, ndipo phindu lazachuma likuwonekera.
4. Zosintha za vacuum zimagwiritsidwa ntchito posintha chipika chilichonse cha fyuluta.Dongosolo lodzilamulira lodziwikiratu ndi mwatsatanetsatane ndipo ntchito zosamalira zimakhala zangwiro, monga chitetezo chamakono, chitetezo chamagetsi, chitetezo chamakono, etc. Ntchito yeniyeniyo ndi yodalirika ndipo ntchitoyo ndi yosavuta.
Ubwino wa Harmonic Governance:
1. Pambuyo poika zida zoyendetsera pulse panopa, mphamvu ya harmonic ikhoza kuchepetsedwa momveka bwino, kuchuluka kwa mphamvu ya transformer kukhoza kuwonjezeka, mphamvu yonyamulira chingwe ikuwonjezekanso, ndipo ndalama za polojekiti zomwe zimafunikira kuti ziwonjezeke zimachepetsedwa.
2. Pambuyo poyika zida zoyendetsera pulse panopa, kutayika kwa transformer kungachepetsedwe bwino, ndondomeko yoyendetsera ntchito yotetezeka ya transformer ikhoza kukonzedwa bwino, ndipo cholinga cha kupulumutsa mphamvu ndi kuchepetsa utsi chikhoza kutheka.
Mayankho omwe mungasankhe:
plan 1
Kwa kasamalidwe kapakati (oyenera ng'anjo zingapo zomwe zimagawana thiransifoma imodzi ndikugwira ntchito nthawi imodzi, chipinda chogawa magetsi chimakhala ndi chipangizo cholipirira zosefera)
1. Gwiritsani ntchito nthambi yolamulira ya harmonic (5, 7, 11 fyuluta) + nthambi yoyendetsera mphamvu yogwira ntchito.Chida cholipirira chosefera chikayamba kugwira ntchito, chiwongolero cha harmonic ndi kubwezeranso mphamvu kwamagetsi amakwaniritsa zofunikira.
2. Adopt yogwira fyuluta (chotsani dongosolo la ma harmonics amphamvu) ndi harmonic countermeasure nthambi dera (5, 7, 11 dongosolo fyuluta) # + chosayenera kusintha nthambi dera, ndipo mutatha kupereka kwa fyuluta zida chipukuta misozi, perekani patsogolo Pempho la chipukuta misozi cholakwika cha dongosolo lamagetsi.
3. Gwiritsani ntchito zida zolipirira zolakwika (5.5%, 6% reactors) kupondereza ma harmonics, ndipo mutatha kuyika zida zolipirira zosefera, zimafunikira makina opangira magetsi kuti apereke chipukuta misozi.
Nkhani 2
Kuwongolera pamalo (khazikitsani gulu lolipirira zosefera pafupi ndi gulu lamagetsi la ng'anjo ya monocrystalline silicon)
1. Nthambi yolamulira ya Harmonic (5, 7, 11 kusefa) imatengedwa, ndipo mphamvu yogwira ntchito ya harmonic imafika pamtunda pambuyo polowera.
2. Sankhani riyakitala yoteteza ndi fyuluta yamagetsi yapawiri-loop (5th ndi 7th fyuluta) kuti mupewe kukopana, ndipo pulse panopa pambuyo kugwirizana sikudutsa ndondomeko.
