Ukulahleka kwe-Photovoltaic Power Station?

Ukulahleka kwesiteshi samandla kususelwa ekulahlekelweni kwe-Photovoltaic Array Adrorption Ukulahleka nokulahleka kwe-Inverter
Ngaphezu komthelela wezici zomthombo, umphumela wezitshalo zamandla ze-Photovoltaic nazo ziyathinteka ekulahlekelweni kokukhiqizwa kwesiteshi samandla nemishini yokusebenza. Lapho kukhululwa khona umshini wokulahleka kwamandla esiteshini, omncane isizukulwane samandla. Ukulahleka Kwemishini Ye-Photovoltaic Power Station ikakhulukazi kuhlanganisa izigaba ezine: Ukulahleka kwe-Photovoltaic Square Array Adrorption Ukulahleka, Ukulahleka Kwamandla, Umugqa Wokuqoqwa Kwamandla kanye nokulahleka kwesiteshi sebhokisi, njll.

Ngemuva kokuhlaziya idatha ka-Okthoba yamandla kagesi ama-Photovoltaic ngokusebenza okuphelele kwama-65% kuya ku-75% kanye ne-20mw kanye ne-50mw, ukulahleka kwe-inverter kuyizinto eziphambili ezithinta umphumela wesiteshi samandla. Phakathi kwazo, i-Photovoltaic array ilahlekelwe kakhulu, i-accounting cishe ama-20 ~ 30%, alandelwa ukulahleka kwe-inverter, ukulahleka kwamandla okuguquguquka kwamandla okusebenza kwama-2 ~ 4%.
Ukuhlaziywa okuqhubekayo kwesiteshi samandla kagesi esishiwo ngenhla, ukutshala imali kwalo kokwakha kungama-yuan angama-400 ezigidi. Ukulahleka kwamandla kwesiteshi samandla ngo-Okthoba kwakungu-2 746,600 kWh, kubangelwa ama-34.8% esizukulwaneni samandla e-theory. Uma kubalwa ku-1.0 yuan ngehora le-kilowatt ngehora, inani ngo-Okthoba ukulahleka kwakungu-4,119,900 yuan, owayenomthelela omkhulu ezinzuzweni zezomnotho zesiteshi samandla.

Ungakunciphisa kanjani ukulahleka kwesiteshi samandla we-Photovoltaic futhi kwandise ukukhiqizwa kwamandla
Phakathi kwezinhlobo ezine zokulahleka kwemishini yezitshalo zamandla e-Photovoltaic, ukulahleka komugqa wokuqoqa kanye ne-box transformer kanye nokulahleka kwesiteshi sokuBooster kuvame ukuhlobene kakhulu nokusebenza kwemishini uqobo, futhi ukulahleka kuzinzile. Kodwa-ke, uma imishini yehluleka, kuzodala ukulahleka okukhulu kwamandla, ngakho-ke kuyadingeka ukuqinisekisa ukusebenza kwayo okujwayelekile nokuzinzile. Okwe-Photovoltaic arrays kanye ne-inverters, ukulahleka kungancishiswa ngokwakha kusenesikhathi nasekusebenzeni kwakamuva nokunakekelwa. Ukuhlaziywa okuthile kungokulandelayo.

(1) Ukwehluleka nokulahleka kwamamojula we-Photovoltaic kanye nemishini yebhokisi le-combiner
Kunemishini yokutshala yamandla e-PhotoVoltaic Power. Isitshalo samandla esingu-30mw Photovoltaic ngalesi sibonelo esingenhla sinamabhokisi ahlanganisiwe angama-420, ngalinye linamagatsha ayi-16 (linamagatsha ayi-6720), futhi inani ngalinye lamabhethri), inani eliphelele lemishini) Lapho likhudlwana inani, likhuphuka imvamisa yokwehluleka kwemishini kanye nokulahleka kwamandla. Izinkinga ezijwayelekile zifaka phakathi ukushiswa kwamamojula we-Photovoltaic, umlilo ebhokisini lokuhlangana, amaphaneli ebhethri aphukile, amaphaneli ebhethri ebhilidi, ukuqinisa ukwamukelwa kwale ngxenye futhi kuqinisekiswe ngezindlela ezisebenzayo zokuhlola kanye nokwamukela. Izinga lemishini yesiteshi samandla lihlobene nekhwalithi, kufaka phakathi ikhwalithi yemishini yefektri, ukufakwa kwamathuluzi kanye nokuhlelwa okuhlangabezana namazinga okuqamba, kanye nekhwalithi yokwakha yesiteshi samandla. Ngakolunye uhlangothi, kuyadingeka ukuthuthukisa izinga lokusebenza elihlakaniphile lesiteshi samandla bese uhlaziya idatha yokusebenza ngokusebenzisa izindlela ezisebenzayo zokuthola ubunzima, yenza ukuxazulula izinkinga zomsebenzi, bese unciphisa ukulahleka kwesiteshi samaphoyinti, futhi kunciphise ukulahleka kwesiteshi samaphoyinti, futhi kunciphise ukulahleka kwesiteshi samaphoyinti, futhi kunciphise ukulahleka kwesiteshi samaphoyinti.
(2) ukulahleka komthunzi
Ngenxa yezinto ezifana ne-angle yokufaka kanye nokuhlelwa kwamamojula we-Photovoltaic, amanye amamojula we-Photovoltaic avinjelwe, okuthinta umphumela wamandla we-Photovoltaic uhlu futhi kuholele ekulahlekelweni kwamandla. Ngakho-ke, ngesikhathi sokwakhiwa nokwakhiwa kwesiteshi samandla, kuyadingeka ukuvikela amamojula we-Photovoltaic ukuba abe semthunzini. Ngasikhathi sinye, ukuze kuncishiswe umonakalo kumamojula we-Photovoltaic yi-Hot Spot Phenomenon, inani elifanelekile le-Bypass Dianes kufanele lifakwe ukuhlukanisa umucu webhethri ezingxenyeni eziningana, ukuze i-turtage string string kanye namanje ilahlekelwe ngokulinganayo ukunciphisa ukulahleka kukagesi.

(3) ukulahleka kwe-angle
I-angle yokuthambekela ye-array ye-Photovoltaic iyahlukahluka kusuka ku-10 ° kuya ku-90 ° kuya ngenhloso, futhi ubude buvame ukukhethwa. Ukukhethwa kwe-angle kuthinta ubukhulu bemisebe yelanga ngakolunye uhlangothi, ngakolunye uhlangothi, isizukulwane samandla amamojula we-photovoltaic siyathinteka ezintweni ezifana nothuli neqhwa. Ukulahleka kwamandla okubangelwa isembozo seqhwa. Ngasikhathi sinye, i-angle yamamojula we-Photovoltaic ingalawulwa izindlela ezihlakaniphile ezisebenzayo ukuzivumelanisa nezinguquko ezinkathini zonyaka kanye nesimo sezulu, futhi wandise amandla okuphehla amandla esiteshini samandla.
(4) Ukulahleka kwe-Inverter
Ukulahleka kwe-inverter kuboniswa ikakhulukazi ezicini ezimbili, okukodwa ukulahleka okubangelwa ukusebenza kahle kwe-inverter, kanti okunye ukulahleka okubangelwa amandla okulandela amandla e-MPPT main power we-inverter. Zombili izici zinqunywa ngokusebenza kwe-inverter uqobo. Inzuzo yokunciphisa ukulahleka kwe-inverter ngokusebenza kamuva nokulungiswa kuncane. Ngakho-ke, ukukhethwa kwemishini esigabeni sokuqala sokwakhiwa kwesiteshi samandla kukhiyiwe, futhi ukulahleka kuncishiswa ngokukhetha i-inverter ngokusebenza okungcono. Esigabeni sokusebenza kwakamuva kanye nesondlo, idatha yokusebenza ye-inverter ingaqoqwa futhi ihlaziywe ngezindlela ezihlakaniphile ukuhlinzeka ukwesekwa kwezinqumo zokukhethwa kwamathuluzi esiteshini samandla esiteshini esisha.

Ukusuka ekuhlaziyweni okungenhla, kungabonakala ukuthi ukulahleka kuzokwenza ukulahleka okukhulu ezitshalweni zamandla we-photovoltaic, kanye nokusebenza okuphelele kwesitshalo samandla kufanele kuthuthukiswe ngokunciphisa ukulahleka ezindaweni ezibalulekile kuqala. Ngakolunye uhlangothi, kusetshenziswa amathuluzi okwamukela okusebenzayo ukuqinisekisa ikhwalithi yemishini nokwakhiwa kwesiteshi samandla; Ngakolunye uhlangothi, enqubweni yokusebenza kwesiteshi samandla nokulungiswa, kuyadingeka ukusebenzisa izindlela ezisebenzayo ezisebenzayo ukwenza ngcono ukukhiqizwa kanye nezinga lokusebenza kwesiteshi samandla futhi kwandise isizukulwane samandla.
