Mhuri iyo DC/AC Power Ratio dhizaini mhinduro

Mukugadzirwa kweiyo photovoltaic power station system, chiyero cheiyo yakaiswa simba reiyo photovoltaic modules kune yakayerwa kugona kweiyo inverter ndeye DC / AC Power Ratio,

Mu "Photovoltaic Power Generation System Efficiency Standard" yakabudiswa muna 2012, huwandu hwehuwandu hunogadzirwa maererano ne1: 1, asi nekuda kwesimba remamiriro echiedza uye kupisa, photovoltaic modules haigoni kusvika simba rezita nguva zhinji, uye iyo inverter zvakanyanya Yese iri kumhanya isingasviki huwandu hwakazara, uye yakawanda yenguva iri padanho rekuparadza simba.

Muchiyero chakaburitswa mukupera kwaGumiguru 2020, huwandu hwehuwandu hwemagetsi emagetsi ephotovoltaic hwakasunungurwa zvakazara, uye chiyero chepamusoro chezvikamu uye inverters chakasvika 1.8: 1.Iyo chiyero chitsva ichawedzera zvakanyanya kudiwa kwemba kwezvikamu uye inverters.Inogona kuderedza mari yemagetsi uye kukurumidza kusvika kwekanguva ye photovoltaic parity.

Iri pepa richatora yakagoverwa photovoltaic system muShandong semuenzaniso, uye kuiongorora kubva pakuona kweiyo chaiyo yakabuda simba re photovoltaic modules, chiyero chekurasikirwa kunokonzerwa nepamusoro-kupa, uye hupfumi.

Parizvino, chiyero chepamusoro-kupihwa kwemagetsi emagetsi e photovoltaic munyika ari pakati pe120% ne140%.Chikonzero chikuru chekuwedzera-kupa ndechekuti maPV modules haakwanise kusvika kune yakanakisa peak simba panguva yekushanda chaiko.Zvinhu zvinokurudzira zvinosanganisira:

1).Kusakwana kwemwaranzi intensity (muchando)

2).Ambient tembiricha

3)) Tsvina uye Dust Kuvharira

4) Solar module orientation haina kunaka mukati mezuva rose (mabhuraketi ekutevera ari mashoma echimwe chinhu)

5) Solar module attenuation: 3% mugore rokutanga, 0.7% pagore pashure pacho.

6) .Kufananidza kurasikirwa mukati uye pakati petambo dze solar modules

Zuva nezuva kugadzirwa kwemagetsi macurves ane akasiyana pamusoro-yekupa reshiyo

Mumakore achangopfuura, chiyero chepamusoro-chepamusoro che photovoltaic systems chakaratidza kuwedzera kwemaitiro.

Kuwedzera kune zvikonzero zvekurasikirwa kwehurongwa, kuwedzera kuderera kwemitengo yezvikamu mumakore achangopfuura uye kuvandudzwa kweinverter tekinoroji zvakakonzera kuwedzera kwenhamba yetambo dzinogona kubatanidzwa, zvichiita kuti kuwedzeredza kuwedzere uye kuwedzera hupfumi. , kupiwa kwepamusoro-soro kwezvikamu kunogonawo kuderedza mari yemagetsi, nokudaro kuvandudza chiyero chemukati chekudzoka kwepurojekiti, saka kukwanisa kurwisana nenjodzi kwekutsvaga kweprojekti kunowedzera.

Mukuwedzera, ma-high-power photovoltaic modules ave ari maitiro makuru mukugadzirwa kweiyo photovoltaic industry panguva ino, iyo inowedzera kuwedzera mukana wekuwedzera-kugovera kwezvikamu uye kuwedzera kweimba photovoltaic yakaiswa simba.

Zvichienderana nezvikonzero zviri pamusoro apa, kuwedzeredza-kupa kwave kuri kuita kweiyo photovoltaic chirongwa chekugadzira.

Kutora iyo 6kW yemhuri photovoltaic magetsi chiteshi chakaiswa nemuridzi semuenzaniso, LONGi 540W modules, iyo inowanzoshandiswa mumusika wakagoverwa, inosarudzwa.Inofungidzirwa kuti avhareji ye20 kWh yemagetsi inogona kugadzirwa pazuva, uye gore negore simba rekugadzira simba rinenge 7,300 kWh.

Maererano nemagetsi emagetsi ezvikamu, ikozvino kushanda kwepamusoro pekushanda nzvimbo ndeye 13A.Sarudza mainstream inverter GoodWe GW6000-DNS-30 pamusika.Iyo yakanyanya kupinza ikozvino yeiyi inverter ndeye 16A, iyo inogona kuenderana nemusika wazvino.yakakwirira yezvino zvikamu.Kutora 30-gore avhareji kukosha kwegore rose kwemwaranzi yemwenje zviwanikwa muYantai Guta, Shandong Province sereferensi, masisitimu akasiyana-siyana ane akasiyana pamusoro-chikamu reshiyo akaongororwa.

2.1 system inoshanda

Kune rimwe divi, kupa-kuwedzeredza kunowedzera kugadzirwa kwemagetsi, asi kune rumwe rutivi, nekuda kwekuwedzera kwenhamba yemamodule ezuva padivi reDC, kurasikirwa kwakafanana kwemasolar module mutambo yezuva uye kurasikirwa kwe DC mutsara wekuwedzera, saka kune yakakwana yehuwandu hwehuwandu, kuwedzera kushanda kweiyo system.Mushure mePVsyst simulation, iyo system inoshanda pasi peakasiyana mareshiyo eiyo 6kVA system inogona kuwanikwa.Sezvinoratidzwa mutafura iri pasi apa, kana huwandu hwehuwandu huri pamusoro pe 1.1, kushanda kwegadziriro kunosvika pakakwirira, izvo zvinorevawo kuti kushandiswa kwehuwandu hwezvikamu ndiyo yakakwirira panguva ino.

Kushanda kweSistimu uye kugadzirwa kwemagetsi kwegore kune akasiyana mareshiyo

2.2 kugadzirwa kwemagetsi nemari

Zvinoenderana nemaitiro ehurongwa pasi peakasiyana pamusoro-yekupa ratios uye theoretical yekuora mwero wemamodule mumakore makumi maviri, gore negore kugadzirwa kwemagetsi pasi peakasiyana-anopa ratios anogona kuwanikwa.Zvinoenderana ne-on-grid magetsi mutengo we 0.395 yuan/kWh (mutengo wemagetsi webenchmark yemarasha desulfurized muShandong), mari yegore rekutengesa magetsi inoverengerwa.Mibairo yekuverenga inoratidzwa mutafura iri pamusoro.

2.3 Kuongorora kwemari

Mutengo ndiwo unonyanya kufunga nezvevashandisi veimba photovoltaic mapurojekiti.Pakati pavo, photovoltaic modules uye inverters ndiyo huru yezvigadzirwa zvekushandisa, uye zvimwe zvinhu zvinobatsira zvakadai se photovoltaic brackets, midziyo yekudzivirira uye tambo, pamwe chete nekuisa-inoenderana mari yeprojekti. kuvaka.Uyezve, vashandisi vanofanirawo kufunga nezvemutengo wekuchengetedza photovoltaic magetsi emiti.Mutengo wepakati pekugadzirisa unotora 1% kusvika 3% yemutengo wekudyara.Mumutengo wakazara, photovoltaic modules account ye50% kusvika 60%.Zvichienderana nemutengo wepamusoro wekushandisa zvinhu, iyo yazvino imba photovoltaic mutengo weyuniti mutengo wakada kuratidzwa mune inotevera tafura:

Zvinogona kuonekwa kubva pakuongorora kwepamusoro kuti kunyange zvazvo simba regore negore rekugadzira uye mari ichawedzera nekuwedzera kwehuwandu hwekupa huwandu, mari yekudyara ichawedzerawo.Mukuwedzera, tafura iri pamusoro apa inoratidza kuti hurongwa hwekugadzirisa huri 1.1 nguva yakawanda Yakanakisisa kana yakabatanidzwa.Saka, kubva pane imwe nyanzvi yekuona, 1.1x yakawandisa inokwana.

Zvisinei, kubva pakuona kwevatengesi, hazvina kukwana kufunga nezvekugadzirwa kwe photovoltaic systems kubva kune unyanzvi hwehutano.Izvo zvinodiwawo kuongorora kukanganisa kwe-over-allocation pamari yekudyara kubva pakuona kwehupfumi.

Zvinoenderana nemutengo wekudyara uye mari yekugadzira magetsi pasi peiyo iri pamusoro akasiyana chiyero chesimba, iyo kWh mutengo weiyo sisitimu yemakore makumi maviri uye pre-mutero wemukati mwero wekudzoka unogona kuverengerwa.

LCOE uye IRR pasi peakasiyana overprovisioning ratios

Sezvinoonekwa kubva pamufananidzo uri pamusoro, kana huwandu hwekugovanisa hudiki, kugadzirwa kwemagetsi uye mari yehurongwa inowedzera nekuwedzera kwechiyero chekugovera, uye iyo yakawedzera mari panguva ino inogona kuvhara mari yakawedzerwa nekuda kwekupfuura. kugoverwa.Kana chiyero chemasimba chakanyanya kukura, chiyero chemukati chekudzoka kwegadziriro zvishoma nezvishoma chinoderera nekuda kwezvinhu zvakadai sekuwedzera zvishoma nezvishoma mumuganhu wesimba rechikamu chakawedzerwa uye kuwedzera kwekurasikirwa kwemutsara.Kana huwandu hwehuwandu huri 1.5, chiyero chemukati chekudzoka IRR chekudyara kwehurongwa ndicho chikuru.Saka, kubva pakuona kwehupfumi, 1.5: 1 ndiyo yakakwana yehuwandu hwehuwandu hwegadziriro ino.

Kuburikidza nenzira imwechete seya pamusoro, iyo yakakwana yehuwandu hwehuwandu hwehurongwa huri pasi pehunyanzvi hwakasiyana hunoverengerwa kubva pamaonero ehupfumi, uye mhedzisiro yacho ndeiyi:

Nekushandisa iyo solar resource data yeShandong, pasi pemamiriro eakasiyana ehuwandu hwehuwandu, simba reiyo photovoltaic module inobuda inosvika kune inverter mushure mekurasika inoverengerwa.Kana huwandu hwehuwandu huri 1.1, kurasikirwa kwehurongwa ndiko kuduku, uye chikamu chekushandiswa kwechikamu ndicho chepamusoro-soro panguva ino.Zvisinei, kubva kune imwe nzvimbo yehupfumi, apo huwandu hwehuwandu huri 1.5, mari yemapurojekiti e photovoltaic ndiyo yakakwirira. .Paunenge uchigadzira photovoltaic system, kwete chete chiyero chekushandiswa kwezvikamu pasi pezvinhu zveunyanzvi zvinofanirwa kutariswa, asiwo hupfumi ndiyo kiyi yekugadzira chirongwa.Kuburikidza nekuverenga kwehupfumi, 8kW system 1.3 ndiyo inodhura zvakanyanya kana ichinge yakawandisa, 10kW system 1.2 ndiyo inodhura zvakanyanya kana ichinge yawandisa, uye 15kW system 1.2 ndiyo inodhura zvakanyanya kana ichinge yawandisa. .

Kana iyo nzira imwe chete inoshandiswa pakuverengera kwehupfumi hwehuwandu hwehuwandu muindasitiri nekutengeserana, nekuda kwekuderedzwa kwemutengo pawatt yehurongwa, iyo yehupfumi optimal capacity reshiyo ichave yakakwirira.Mukuwedzera, nekuda kwezvikonzero zvemusika, mari ye photovoltaic systems ichasiyanawo zvikuru, iyo ichaitawo zvakanyanya kuverengwa kwehuwandu hwehuwandu hwehuwandu.Ichi ndichowo chikonzero chakakosha nei nyika dzakasiyana-siyana dzakaburitsa zvirambidzo pachiyero chekugadzirisa kweiyo photovoltaic system.
