Mumakore achangopfuura, photovoltaic simba rekugadzira tekinoroji yakafambira mberi nekusvetuka uye miganhu, uye yakaiswa simba yakawedzera nekukurumidza. Zvisinei, photovoltaic simba rekugadzira rine zvikanganiso zvakadai sepakati uye zvisingadzoreki. Isati yabatwa, yakakura-yakananga yakananga kugetsi yemagetsi ichaunza hukuru hukuru uye inokanganisa kushanda kwakagadzikana kwemagetsi emagetsi. . Kuwedzera simba rekuchengetedza magetsi kunogona kuita kuti photovoltaic simba rekugadzira zvigadziriswe zvakanaka uye zvakagadzikana kubuda kune gridhi, uye hukuru-hukuru hwekuwana kune grid hahuzokanganisa kugadzikana kwegridhi. Uye photovoltaic + kuchengetedza simba, iyo system ine yakakura application renji.
Photovoltaic kuchengetedza system, kusanganisira solar modules, controllers,inverters, mabhatiri, mitoro nemimwe michina. Parizvino, kune nzira dzakawanda dzehunyanzvi, asi simba rinoda kuunganidzwa pane imwe nzvimbo. Parizvino, pane kunyanya maviri epamusoro: DC coupling "DC Coupling" uye AC coupling "AC Coupling".
1 DC yakabatanidzwa
Sezvinoratidzwa mumufananidzo uri pasi apa, simba reDC rinogadzirwa ne photovoltaic module rinochengetwa mubhatiri pack kuburikidza nemutongi, uye grid inogonawo kuchaja bhatiri kuburikidza ne bidirectional DC-AC converter. Nzvimbo yekuunganidzira yesimba iri panoperera bhatiri reDC.
Nheyo yekushanda yeDC coupling: kana photovoltaic system iri kushanda, mutungamiri weMPPT anoshandiswa kutengesa bhatiri; apo mutoro wemagetsi uri kudiwa, bhatiri ichasunungura simba, uye ikozvino inotarirwa nemutoro. Iyo simba rekuchengetedza sisitimu yakabatana kune grid. Kana mutoro wacho uri muduku uye bhatiri yakazara zvakakwana, photovoltaic system inogona kupa simba kune gridhi. Kana simba remutoro rakakura kudarika simba rePV, grid nePV inogona kupa simba kumutoro panguva imwe chete. Nekuti photovoltaic simba rekugadzira uye mutoro wekushandisa simba hauna kugadzikana, zvinodikanwa kuvimba nebhatiri kuenzanisa simba rehurongwa.
2 AC yakabatanidzwa
Sezvinoratidzwa mumufananidzo uri pasi apa, iyo yakananga ikozvino inogadzirwa ne photovoltaic module inoshandurwa kuva alternating current kuburikidza ne inverter, uye inodyiswa zvakananga kumutoro kana kutumirwa kune gridhi. Iyo grid inogona zvakare kuchaja bhatiri kuburikidza nebidirectional DC-AC bidirectional converter. Nzvimbo yekuunganidza simba iri pamagumo ekutaurirana.
Iyo yekushanda musimboti we AC coupling: inosanganisira photovoltaic magetsi ekupa system uye bhatiri magetsi ekupa system. Iyo photovoltaic system inosanganisira photovoltaic arrays uye grid-yakabatana inverters; iyo bhatiri system ine bhatiri packs uye bidirectional inverters. Aya masisitimu maviri anogona kushanda akazvimirira pasina kupindirana, kana anogona kupatsanurwa kubva kune yakakura magetsi grid kuti agadzire micro-grid system.
Zvese zviri zviviri kubatanidza DC uye AC coupling parizvino mhinduro dzakakura, imwe neimwe iine zvayakanakira nezvayakaipira. Maererano nemashandisirwo akasiyana, sarudza mhinduro yakakodzera. Izvi zvinotevera kuenzanisa kwezvigadziriso zviviri.
1 mutengo wekuenzanisa
DC coupling inosanganisira controller, bidirectional inverter uye transfer switch, AC coupling inosanganisira grid-yakabatana inverter, bidirectional inverter uye magetsi ekugovera kabati. Kubva pakuona kwemutengo, mutongi anodhura kupfuura grid-yakabatana inverter. Iyo yekuchinjisa switch zvakare yakachipa pane kabati yekugovera magetsi. Iyo DC yekubatanidza chirongwa inogona zvakare kugadzirwa kuita yekudzora uye inverter yakasanganiswa muchina, inogona kuchengetedza mutengo wemidziyo uye mitengo yekuisa. Naizvozvo, mutengo weDC coupling scheme wakadzikira zvishoma pane weiyo AC coupling scheme.
2 Kushanda kwekuenzanisa
DC coupling system, controller, bhatiri uye inverter zvakabatana munhevedzano, kubatana kuri padyo, asi kuchinjika kwakashata. Mune AC coupling system, grid-yakabatana inverter, bhatiri rekuchengetedza uye bidirectional converter inofanana, kubatana hakuna kuoma, uye kushanduka kwakanaka. Semuenzaniso, mune yakatogadzikwa photovoltaic system, zvakakosha kuisa simba rekuchengetedza simba, zviri nani kushandisa AC coupling, chero bhatiri uye bidirectional converter yakaiswa, hazvizokanganisa iyo yekutanga photovoltaic system, uye iyo simba rekuchengetedza sisitimu Mumutemo, iyo dhizaini haina hukama hwakananga neiyo photovoltaic system uye inogona kutsanangurwa maererano nezvinodiwa. Kana iri ichangobva kuisirwa off-grid system, photovoltaics, mabhatiri, uye inverters dzinofanirwa kugadzirwa zvinoenderana nemushandisi wemutoro simba uye mashandisiro emagetsi, uye DC coupling system inonyanya kukodzera. Nekudaro, simba reiyo DC coupling system idiki, kazhinji iri pasi pe500kW, uye zviri nani kudzora yakakura sisitimu neAC coupling.
3 kunyatso kuenzanisa
Kubva pakuona kwe photovoltaic utilization performance, zvirongwa zviviri izvi zvine maitiro avo. Kana mushandisi akatakura zvakawanda mukati mezuva uye zvishoma usiku, zviri nani kushandisa AC coupling. Iyo photovoltaic modules inopa zvakananga simba kumutoro kuburikidza negridhi-yakabatana inverter, uye kubudirira kunogona kusvika Kupfuura 96%. Kana mutoro wemushandisi uri muduku mukati mezuva uye zvakanyanya usiku, uye photovoltaic simba rekugadzira rinoda kuchengetwa masikati uye rinoshandiswa usiku, zviri nani kushandisa DC coupling. Iyo photovoltaic module inochengetedza magetsi kune bhatiri kuburikidza nemutongi, uye kubudirira kunogona kusvika kupfuura 95%. Kana iri AC coupling, Photovoltaics inofanira kutanga yashandurwa kuva AC simba kuburikidza ne inverter, uye yozoshandurwa kuva DC simba kuburikidza ne bidirectional converter, uye kushanda kwayo kuchadonha kusvika ku90%.
Ameninsolar'sN3Hx yakatevedzana yakakamurwa chikamu invertersinotsigira AC coupling uye yakagadzirirwa kusimudzira solar simba masisitimu. Tinotambira vaparidzi vakawanda kuti vabatane nesu mukusimudzira zvigadzirwa zvitsva izvi. Kana iwe uchifarira kuwedzera chigadzirwa chako chinopihwa uye nekupa emhando yepamusoro inverters kune vatengi vako, tinokukoka iwe kuti ubatane nesu uye ubatsirwe kubva kune yepamusoro tekinoroji uye kuvimbika kweiyo N3Hx yakatevedzana. Bata nesu nhasi kuti tiongorore uyu mukana unonakidza wekubatana uye kukura muindasitiri yesimba rinowanikwazve.
