Mumakwikwi anotyisa e "grid parity" muindasitiri yephotovoltaic, mutengo wekugadzirisa wekilowatt-awa yega yega yemagetsi une chekuita nekukwikwidza kwekutanga kwemabhizinesi. Sechishandiso chakakosha mukugadzira solar cell modules, iko kurongeka kwepuratifomu inofamba yephotovoltaic tambo welding muchina inobata zvakananga kunaka kwewelding uye kugona kwekugadzira. Iyo granite inofamba chikuva yakatsaurirwa kune photovoltaic tambo welding michina, ine yekupedzisira dimensional kugadzikana kwe0.5μm/gore, inopa rutsigiro rwehunyanzvi mukudzikisa mutengo pa kilowatt-awa kubva kune akawanda mativi. .
Kugadzikana kwepamusoro kunovimbisa kuti welding yakarurama uye inoderedza tsvina yezvinhu
Munguva yetambo welding process ye photovoltaic masero, kutsauka munzvimbo yewelding kunogona kutungamira mukusabatana kwakabatana kwemaseru, nekudaro kukanganisa kugona kwekugadzira magetsi kwemamodule uye kunyange kugadzira zvigadzirwa zvisina kunaka. Iyo yechinyakare inofamba chikuva inokonzeresa dimensional deformation nekuda kwezvinhu zvakaita sekuchinja kwekushisa kwezvakatipoteredza uye mechanic vibration, zvichikonzera kutsauka munzvimbo yewelding. Iyo coefficient yekuwedzera kwekupisa kwegranite yemitambo yepuratifomu ndeye (4-8) × 10⁻⁶/℃. Yakasanganiswa neyakaomeswa uye yakaenzana chimiro chemukati, dimensional kugadzikana kwe 0.5μm / gore inogona kuwanikwa. .
Kutora 1GW photovoltaic module yekugadzira mutsara semuenzaniso, kana yakajairwa chikuva chekufamba chikagamuchirwa, kutsauka kwenzvimbo yewelding kunokonzerwa nedimensional deformation inodarika 0.1mm, izvo zvinogona kuita kuti chiyero chewelding chemasero ezuva chikwire kusvika pa3%. Paunenge uchishandisa granite mitambo mapuratifomu, iyo welding defect rate inogona kudzorwa mukati me 0.5%. Kune yega yega kuderedzwa kwe1% muyero yekuremara, anopfuura miriyoni imwe yeyuan inokosha yemasero ebhatiri anogona kuchengetwa gore rega rega, achidzikisa zvakananga mutengo wekugadzira wezvikamu uye nekuisa hwaro hwekudzikira kwemutengo pakilowatt-awa. .
Deredza kuwanda kwekugadzirisa kwemidziyo uye kuvandudza kugadzirwa kwakanaka
Chikuva chekufamba chine hurombo husina kugadzikana chinokonzeresa kukurumidza kupera kwemidziyo yekutapurirana uye kudzikira kwenzvimbo nekuda kwedeformation panguva yekushandiswa kwenguva refu, uye nekudaro inoda kugara ichigadziriswa uye kugadzirisa michina. Granite mitambo yemapuratifomu, nekugadzikana kwayo kwakatanhamara, inogona kunyatso kudzikisa kuitika kwematambudziko akadaro. .
Nekuda kweiyo diki dimensional mutsauko we 0.5μm pagore, iyo yekupfeka dhigirii yezvikamu zvakakosha senge nzira yekutapurirana uye yekumisikidza sensor yemuchina wetambo welding inoderedzwa zvakanyanya. Zvinoenderana neiyo chaiyo yekuyera data yeimwe photovoltaic yekugadzira bhizinesi, mushure mekutora granite inofamba chikuva, kutenderera kwekutenderera kwetambo welding muchina wakawedzerwa kubva kamwe pamwedzi kusvika kamwe chete pakota, uye imwe nguva yekuchengetedza yakapfupikiswa kubva kumaawa masere kusvika kumaawa matatu. Kudzikiswa kwehuwandu hwekugadziriswa kwemidziyo kunoreva kukwirira kwekugadzira uye kuderera kwekushandisa kwemidziyo uye mari yekugadzirisa. Zvichienderana netambo yekugadzira ine simba regore re500MW, inogona kuwedzera nguva yekugadzira inoshanda nemaawa angangosvika mazana maviri gore rega rega, kugadzira mamwe mafotovoltaic modules anokosha kupfuura 5 miriyoni yuan, uye zvakanyanya kuderedza mutengo pakilowatt-awa. .
Wedzera hupenyu hwebasa remidziyo uye kuderedza mari yekudyara
Mari yekudyara yemidziyo yekugadzira photovoltaic yakakwira, uye hupenyu hwesevhisi hwemidziyo hunokanganisa zvakananga kudzoka kwekudyara kwemabhizinesi. Nekuda kwekuchinja-kwenguva refu dhimensional uye deformation yezvimiro, akajairwa mafambiro mapuratifomu anowanzo kutadza kusangana nepamusoro-chaiyo kugadzirwa kweanoda kweanopfuura makore mashanu. Nekuda kweizvozvo, mabhizinesi anofanirwa kutsiva zvishandiso pachine nguva, zvichiwedzera kudzvanywa kweiyo inogadziriswa asset investment. .
Mapuratifomu emitambo yeGranite, ane chimiro chayo chakagadzikana uye chemakemikari zvimiro, anogona kuchengetedza yakanyanya kunaka panguva yekushandiswa kwenguva refu uye zvinobudirira kuwedzera hupenyu hwese hwesevhisi yemuchina wetambo welding. Dhata kubva kune imwe photovoltaic midziyo yekugadzira inoratidza kuti tambo welding muchina wakashongedzerwa negranite inofamba chikuva unogona kuramba uchichengetedza welding chinzvimbo mukati me ± 0.1mm mushure mekugara uchishandiswa kwemakore masere, ichisangana nezvinodiwa zvekugadzira zvemhando yepamusoro-inoshanda. Kusiyana neizvi, zvishandiso zvinoshandisa zvakajairika mapuratifomu ekufambisa zvinoda kuti zvigadziriswe zvepakati kana kuti muchina wese uvandudzwe mushure memakore mashanu. Kuwedzerwa kwehupenyu hwesevhisi yemidziyo inogonesa iyo yakatarwa yekudyara mari yemabhizinesi kugovaniswa kwenguva yakareba, zvichiwedzera kudzikisa chikamu chekuderera kwemidziyo mumutengo pa kilowatt-awa. .
Kufambisa kugadzirwa kwezvikamu zvinobudirira uye kuwedzera mari yekugadzira magetsi
Iyo dimensional kugadzikana ye 0.5μm/gore inopa vimbiso kune photovoltaic tambo welding muchina kuti uwane yakakwirira-chaiyo welding, zvichiita kuti mabhizinesi abudise photovoltaic modules nepamusoro-soro. Mumashandisirwo ezviteshi zvemagetsi anoshanda, epamusoro-anoshanda anogona kuwana yakakwira kugadzirwa kwemagetsi uye yakaderera attenuation mwero, nekudaro kuwedzera iyo yese yekugadzira magetsi mari yechiteshi chemagetsi. .
Semuyenzaniso, iwo maviri-mativi maviri-magirazi modules ane yakakwirira-chaiyo welding anogona kuwedzera simba rekugadzira magetsi ne3% kusvika 5% zvichienzaniswa nemamodule akajairwa. Tora 100MW photovoltaic power station semuenzaniso. Nekushandisa zvidimbu zvemhando yepamusoro, inogona kugadzira mamwe 3 kusvika 5 miriyoni kilowatt-maawa emagetsi pagore. Kuwedzera kwemari yekugadzirwa kwemagetsi kunoreva kuderedzwa kwakasiyana kwemutengo pa kilowatt-awa, kuwedzera kuwedzera hupfumi uye kukwikwidza kwemagetsi emagetsi e photovoltaic. .
Iyo granite inofamba chikuva yakatsaurirwa kune photovoltaic tambo welding michina, ine dimensional kugadzikana kwe 0.5μm/gore semubairo wayo mukuru, inoderedza zvakanyanya mutengo wekugadzirwa kwemafotovoltaic modules uye mutengo pa kilowatt-awa yezviteshi zvemagetsi kuburikidza nenzira dzakawanda dzakadai sekuona kurongeka kwakaringana, kudzikisa kugadzirwa kwemidziyo, kusimudzira kugadzirwa kwemidziyo uye kurerutsa midziyo yehupenyu. Iyo inopa yakasimba tekinoroji rutsigiro rweiyo photovoltaic indasitiri kuti iwane "grid parity" uye inoenderera budiriro.
