2017 inozivikanwa segore rekutanga rekugoverwa PHOTOVOLTAIC yeChina, kuwedzera kwegore kwekugoverwa kwePV yakaiswa simba inenge 20GW, inofungidzirwa kuti mhuri yakagoverwa PV yakawedzera nemisha inopfuura 500,000, iyo yezhejiang, Shandong mapurovhinzi maviri e. mhuri PV kuisirwa anopfuura 100,000 mhuri.
Sezvinozivikanwa kune vese, zvichienzaniswa nechiteshi chikuru chemagetsi pasi, nharaunda yedenga yakagoverwa photovoltaic chiteshi chemagetsi chakanyanya kuomarara, kuitira kudzivirira pesvedzero yezvipingamupinyi zvakaita separapet, zvivakwa zvakatenderedza, tambo dzepamusoro, chimney chedenga, solar. heater yemvura, uye kuti udzivise dambudziko rekusiyana kwakanangana nedenga rekuvhenekesa harienderane, inowanika padenga yekuisa nzvimbo ichaderedzwa uye iyo yakaiswa simba ichave shoma.
Kana ichi chikamu chekudzivirira chikasadzivirirwa, chiteshi chemagetsi chinokonzeresa kutevedzana uye kusawirirana kwakafanana nekuda kwekudzivirira kana kusapindirana kwemwenje, uye simba rose rekugadzira magetsi rechiteshi chemagetsi richaderedzwa.Maererano nemishumo yakakodzera yekutsvakurudza, mumvuri wepanzvimbo we photovoltaic modules uchaderedza yose yakatevedzana kugadzirwa kwemagetsi neanopfuura 30%.
Maererano nePVsyst modeling analysis, nekuda kwemaitiro e photovoltaic series, kana simba rekugadzira imwe photovoltaic module rakaderedzwa ne30%, simba rekugadzira zvimwe zvikamu muboka rose richawirawo kune imwechete yakaderera, iyo. ndiyo pfupi bhodhi mhedzisiro yehuni barrel mu photovoltaic group series system.
Tichifunga nezvemamiriro ezvinhu ari pamusoro apa, zvinokurudzirwa kuisa PV simba optimizer, iyo inogona kuzvimiririra kudzora kukwira nekudonha kwePV module yega yega, kugadzirisa matambudziko ekutevedzana uye kusawirirana kwakafanana kwemapoka ephotovoltaic anokonzerwa nekutsemuka kwakavanzika, nzvimbo dzinopisa, kuvharika kwemumvuri, kuchena kwakasiyana, kutaridzika kusingaenderane uye kuvhenekera, uye inogona kuvandudza iyo yakazara simba chizvarwa chehurongwa.
Mhosva nhatu dzakashandiswa kuongorora kushanda kweiyo photovoltaic simba optimizer.
8KW pamusoro pedenga remagetsi chiteshi, huwandu hwekugadzira hwenzvimbo yakagadziridzwa hwakawedzera ne130%, yakagadzira imwe 6 KWH yemagetsi zuva rega rega.
Iyo 8KW imba yemagetsi chiteshi inovakwa pauriri hwechitatu hwechivakwa chekugara.Zvimwe zvikamu zvakaiswa pa balcony canopy uye zvimwe zvikamu zvakaiswa pane tile pamusoro.
Iyo bhatiri module yakasvibiswa nemvura inopisa uye shongwe yemvura iri pedyo, iyo inofananidzwa nePVsyst kwemwedzi gumi nemiviri yegore.Nekuda kweizvozvo, inogadzira 63% mashoma magetsi pane zvaanofanira, chete 8.3 KWH pazuva,
Mushure mekuisirwa optimizer kune iyi nhevedzano, nekuenzanisa chizvarwa chemagetsi mumazuva gumi ezuva risati rasvika uye mushure mekuiswa, kuongororwa kunotevera:
Zuva rekutanga rekushanda kweiyo optimizer raive Zvita 20, panguva imwecheteyo, grey chikamu chekugadzira simba reboka rekuenzanisa chinowedzerwa kuti chiongororwe kusabvisa pesvedzero yemwaranzi, tembiricha uye zvimwe zvinokanganisa.Mushure mekugadzwa kweiyo optimizer, chiyero chekuwedzera kwemagetsi chiyero chiri 130%, uye avhareji yezuva nezuva kuwedzera kwesimba ndeye 6 KWH.
5.5KW pamusoro pedenga remagetsi chiteshi, kugadzirwa kwemagetsi kweiyo optimized cluster yakawedzera ne39.13%, yakagadzira yakawedzera 6.47 KWH yemagetsi mazuva ese.
Kune 5.5kW pamusoro pedenga remagetsi chiteshi chakaiswa mukushanda muna 2017, tambo dzose dziri mbiri dzinobatwa nepekugara miti yakatenderedza, uye kugadzirwa kwemagetsi kwakadzikira pane yakajairika nhanho.
Zvinoenderana nemamiriro chaiwo ekudzivirira pane saiti, modhi uye kuongororwa kunoitwa mupvsyst.Tambo mbiri idzi dzine 20 photovoltaic modules, iyo ichave yakasvibiswa kwemwedzi gumi yegore, ichideredza zvakanyanya simba rose rekugadzirwa kwegadziriro.Kupfupisa, iyo photovoltaic simba optimizer inoiswa pane maviri akatevedzana emakumi maviri module munzvimbo yeprojekiti.
Mushure me 20 photovoltaic power optimizers akaiswa patambo mbiri, nekuenzanisa chizvarwa chemagetsi mumazuva mashanu ezuva risati raiswa uye mushure mekuiswa, kuongororwa kunotevera:
Zuva rekutanga rekushanda kwe optimizer raive Zvita 30, panguva imwecheteyo, grey chikamu chekugadzira simba reboka rekuenzanisa inowedzerwa kuti iongororwe kusabvisa pesvedzero yemwaranzi, tembiricha uye zvimwe zvinokanganisa.Mushure mekugadzwa kweiyo optimizer, chiyero chekuwedzera kwemagetsi chiyero chiri 39.13%, uye avhareji yezuva nezuva kuwedzera kwesimba ndeye 6.47 KWH.
2MW centralized power station, kugadzirwa kwemagetsi kwemapoka mana munzvimbo yeoptimization inowedzerwa ne105.93%, inogadzirwa imwe 29.28 KWH yemagetsi zuva rega rega.
Kune 2MW yepakati penzvimbo yemagetsi yegomo yakaiswa mukushanda muna 2015, iyo-saiti yekudzivirira yemumvuri yakaoma, iyo yakakamurwa zvakanyanya kuita zvikamu zvitatu: simba danda rekudzivirira, kudzivirira miti uye kudiki zvakanyanya kumberi uye kumashure kwepakati kwezvikamu.Iyo yekumberi uye yekumashure inodzivirira yezvikamu ichaonekwa munguva yechando nekuti zuva rekukwirira kona rinova rakaderera, asi kwete muzhizha.Pole shading uye shading yemiti inoitika gore rose.
Iyo modhi yehurongwa hwese inotangwa mupvsyst zvinoenderana nemuenzaniso maparamendi ezvikamu uye inverters muhurongwa, nzvimbo yeprojekiti uye mamiriro chaiwo ekuva shaded.Mumazuva ezuva, kurasikirwa kwemutsara kwechiedza chemwenje ndeye 8.9%.Iyo theoretical value haigone kuwanikwa nekuda kwekurasikirwa kwesimba risingaenzaniswi rinokonzerwa nekusaenderana.
Zvinoenderana nemamiriro esaiti, tambo ina dzakasarudzwa, makumi maviri nemaviri photovoltaic simba optimizers akaiswa mune imwe neimwe tambo, uye yakazara ye88 optimizers yakaiswa.Nekuenzanisa kugadzirwa kwemagetsi kusati kwaiswa uye mushure mekuiswa uye kugadzirwa kwemagetsi kweapadhuze asina kuisirwa optimizer tambo, kuongororwa kunotevera:
Mumazuva ekupisa kwezuva, kukanganiswa kwekuvhenekesa kwemamiriro ekunze kunofanirwa kuderedzwa, uye chikamu chegrey chekugadzira simba rekuenzanisa boka rinoteedzera rinofanirwa kuwedzerwa kuti riongororwe kubvisa kukanganiswa kwehuwandu hwemwaranzi, tembiricha uye humwe huwandu hwekukanganisa.Mushure mekunge iyo optimizer yaiswa, simba rekugadzira chiteshi chemagetsi 105.93% yakakwirira kupfuura iyo panguva iyo isati yaiswa, avhareji yekugadzira magetsi patambo pazuva inowedzerwa ne7.32 KWH, uye kugadzirwa kwesimba kwetambo ina. yakawedzera ne 29.28 KWH pazuva.
Nekuda kwekuderedzwa kwemahombe emagetsi emagetsi uye kuomarara kwezviwanikwa uye zvakatipoteredza zvakaita semakomo, zvinokurudzirwa kuti vanhu vazhinji vashandise nzvimbo yedenga yekuisa photovoltaic system.Isu tinopa yakakwana sisitimu yekuisa hurongwa uye inotevera solar panel yekuchenesa chirongwa.Isu tichagara takazvipira kupa vashandisi simba rakachengeteka, rakagadzikana uye rakavimbika photovoltaic.
