Ndekupi kurasikirwa kwe photovoltaic power station?

Simba chiteshi kurasikirwa kunobva pane photovoltaic array absorption kurasikirwa uye inverter kurasikirwa
Pamusoro pekukanganisa kwezvinhu zvekushandisa, kubuda kwemagetsi emagetsi ephotovoltaic kunokanganisawo nekurasikirwa kwemagetsi ekugadzira chiteshi uye michina yekushandisa. Kukura kwekurasikirwa kwemidziyo yemagetsi, kugadzirwa kwemagetsi kudiki. Iko kurasikirwa kwemidziyo ye photovoltaic chiteshi chemagetsi kunonyanya kusanganisira zvikamu zvina: photovoltaic square array absorption kurasikirwa, inverter kurasikirwa, simba rekuunganidza mutsara uye bhokisi rekushandura kurasikirwa, booster station kurasikirwa, nezvimwe.

(1) Kurasika kwekunyura kweiyo photovoltaic array ndiko kurasikirwa kwesimba kubva kune photovoltaic array kuburikidza nebhokisi rekubatanidza kusvika kuDC yekuisa kupera kweiyo inverter, kusanganisira photovoltaic chikamu chekutadza kurasikirwa kwemidziyo, kurasikirwa kwekudzivirira, kurasikirwa kwekona, DC tambo kurasikirwa, uye musanganisi. bhokisi kurasikirwa kwebazi;
(2) Inverter kurasikirwa inoreva kurasikirwa kwesimba kunokonzerwa ne inverter DC kusvika ku AC kutendeuka, kusanganisira inverter kutendeuka kwekubudirira kurasikirwa uye MPPT yakakura simba rekutsvaga kukwanisa kurasikirwa;
(3) Mutsara wekuunganidza simba uye bhokisi rekushandura kurasikirwa ndiko kurasikirwa kwesimba kubva kuA AC yekuisa kuguma kweiyo inverter kuburikidza nebhokisi rekushandura kusvika kumagetsi emagetsi ebazi rimwe nerimwe, kusanganisira inverter outlet kurasikirwa, bhokisi rekushandura kushandura kurasikirwa uye mu-plant line. kurasikirwa;
(4) Iyo booster station kurasikirwa kurasikirwa kubva pamagetsi emagetsi ebazi rega rega kuburikidza nechiteshi chinosimudzira kuenda kumamita egedhi, kusanganisira kurasikirwa kukuru kweshanduko, kurasikirwa kwechiteshi, kurasikirwa kwebhazi uye kumwe kurasikirwa kwemutsetse wechiteshi.

Mushure mekuongorora data raGumiguru rematatu emagetsi emagetsi emagetsi ane hunyanzvi hwe65% kusvika 75% uye huwandu hwakaiswa hwe20MW, 30MW uye 50MW, mhedzisiro inoratidza kuti photovoltaic array absorption kurasikirwa uye kurasikirwa inverter ndizvo zvinhu zvikuru zvinokanganisa kubuda. yechiteshi chemagetsi. Pakati pavo, iyo photovoltaic array ine yakanyanya kunyura kurasikirwa, inoverengera inosvika 20 ~ 30%, ichiteverwa nekurasikirwa inverter, inoverengera inenge 2 ~ 4%, nepo mutsara wekuunganidza simba uye bhokisi rekuchinja kurasikirwa uye booster chiteshi kurasikirwa kuri kudiki, pamwe nehwerengedzo yeanenge Akaverengerwa kweinenge 2%.
Kumwe ongororo yeyataurwa pamusoro apa 30MW photovoltaic magetsi chiteshi, mari yekuvaka yayo ingangoita 400 miriyoni yuan. Kurasikirwa kwemagetsi kwechiteshi chemagetsi muna Gumiguru kwaive 2,746,600 kWh, inoverengera 34.8% yeiyo theoretical simba rekugadzira. Kana ikaverengerwa pa 1.0 yuan pa kilowatt-awa, yakazara muna Gumiguru Kurasika kwaive 4,119,900 yuan, iyo yakave nemhedzisiro yakakura pahupfumi hwechiteshi chemagetsi.

Nzira yekudzikisa sei kurasikirwa kwe photovoltaic power station uye kuwedzera simba rekugadzira
Pakati pemhando ina dzekurasikirwa kwe photovoltaic power plant equipment, kurasikirwa kwemutsara wekuunganidza uye bhokisi rekushandura uye kurasikirwa kwechiteshi chekusimudzira zvinowanzoenderana nekushanda kwemidziyo pachayo, uye kurasikirwa kunenge kwakagadzikana. Nekudaro, kana iyo midziyo ikakundikana, inokonzeresa kurasikirwa kukuru kwesimba, saka zvinodikanwa kuve nechokwadi chekushanda kwayo kwakajairika uye kwakagadzikana. Kune photovoltaic arrays uye inverters, kurasikirwa kunogona kuderedzwa kuburikidza nekuvaka kwekutanga uye gare gare kushanda nekugadzirisa. Ongororo chaiyo ndeyotevera.

(1) Kukundikana uye kurasikirwa kwe photovoltaic modules uye musanganisi bhokisi midziyo
Kune akawanda photovoltaic power plant equipment. Iyo 30MW photovoltaic power plant mumuenzaniso wepamusoro ine 420 mabhokisi ekubatanidza, rimwe nerimwe rine matavi gumi nematanhatu (mapazi e6720), uye rimwe nerimwe rine mapaneru makumi maviri (mabhatiri e134,400) Bhodhi), iyo yose yemidziyo yakakura. Kuwanda kwenhamba, kunowedzera kuwanda kwekutadza kwemidziyo uye kuwedzera kurasikirwa kwemagetsi. Zvinetso zvakajairika zvinonyanya kusanganisira kupiswa kunze kwe photovoltaic modules, moto pabhokisi rekubatanidza, kuputsika kwebheteri panels, nhema welding yevatungamiri, zvikanganiso mubazi redunhu rebhokisi rekubatanidza, nezvimwewo Kuti uderedze kurasikirwa kwechikamu ichi, pane imwe. ruoko, tinofanira kusimbisa kupedzisa kubvuma uye nechokwadi kuburikidza zvinobudirira ongororo uye kugamuchirwa nzira. Hunhu hwemagetsi chiteshi chemagetsi chine hukama nemhando, kusanganisira mhando yemidziyo yefekitori, kuisirwa kwemidziyo uye kurongeka kunoenderana nemaitiro ekugadzira, uye kunaka kwekuvaka kwechiteshi chemagetsi. Nekune rimwe divi, zvinodikanwa kuvandudza hungwaru hwekuita basa rechiteshi chemagetsi uye kuongorora iyo data yekushandisa kuburikidza nehungwaru nzira dzekubatsira kuti uzive nekufamba kwenguva Fault source, ita-point-to-point kugadzirisa, kuvandudza mashandiro ekushanda. nevashandi vekuchengetedza, uye kuderedza kurasikirwa kwechiteshi chemagetsi.
(2) Shading kurasikirwa
Pamusana pezvinhu zvakadai sekona yekuisa uye kurongeka kwe photovoltaic modules, mamwe ma photovoltaic modules akavharwa, izvo zvinokanganisa simba rekubuda kwe photovoltaic array uye zvinotungamirira pakurasikirwa kwesimba. Nokudaro, panguva yekugadzira uye kuvakwa kwechiteshi chemagetsi, zvakakosha kudzivirira ma photovoltaic modules kubva mumumvuri. Panguva imwecheteyo, kuitira kuderedza kukuvadzwa kwe photovoltaic modules nechiitiko chinopisa, nhamba yakakodzera ye bypass diodes inofanira kuiswa kuti iparadzanise tambo yebhatiri muzvikamu zvakawanda, kuitira kuti bhatiri tambo voltage uye Ikozvino inorasika. zvakaenzana kuderedza kurasikirwa kwemagetsi.

(3) Kurasika kwekona
Iyo inclination angle ye photovoltaic array inosiyana kubva 10 ° kusvika 90 ° zvichienderana nechinangwa, uye latitude inowanzosarudzwa. Kusarudzwa kwemakona kunokanganisa kusimba kwezuva kune rumwe rutivi, uye kune rumwe rutivi, simba rekugadzira photovoltaic modules rinokanganiswa nezvinhu zvakadai seguruva nechando. Kupera simba kunokonzerwa nechando chivharo. Panguva imwecheteyo, kona ye photovoltaic modules inogona kudzorwa nehungwaru nzira dzekubatsira kugadzirisa kuchinja kwemwaka uye mamiriro ekunze, uye kuwedzera simba rekugadzira simba rechiteshi chemagetsi.
(4) Inverter kurasikirwa
Inverter kurasikirwa kunonyanya kuratidzwa muzvikamu zviviri, imwe ndiyo kurasikirwa kunokonzerwa nekushandurwa kwekushanda kweiyo inverter, uye imwe ndiyo kurasikirwa kunokonzerwa neMPPT yakakura simba rekutsvaga simba rekushandura. Zvose zviri zviviri zvinogadziriswa nekushanda kweiyo inverter pachayo. Kubatsira kwekudzikisa kurasikirwa kweinverter kuburikidza nekushanda kwekupedzisira nekugadzirisa zvishoma. Nokudaro, kusarudzwa kwemidziyo panguva yekutanga yekuvakwa kwechiteshi chemagetsi yakavharwa, uye kurasikirwa kunoderedzwa nekusarudza inverter nekushanda kwakanaka. Muchikamu chekupedzisira chekushanda nekugadzirisa, iyo data yekushanda ye inverter inogona kuunganidzwa uye kuongororwa nenzira dzakangwara kuti ipe rutsigiro rwesarudzo yekusarudzwa kwemidziyo yechiteshi chemagetsi chitsva.

Kubva pakuongorora kwepamusoro, zvinogona kuonekwa kuti kurasikirwa kunokonzera kurasikirwa kukuru mumagetsi emagetsi e photovoltaic, uye kushanda kwese kwesimba remagetsi kunofanira kuvandudzwa nekuderedza kurasikirwa munzvimbo dzinokosha kutanga. Kune rimwe divi, maturusi ekugamuchira anobudirira anoshandiswa kuve nechokwadi chemhando yemidziyo uye kuvakwa kwechiteshi chemagetsi; nerumwe rutivi, mukuita basa remagetsi chiteshi uye kugadzirisa, zvinodikanwa kushandisa zvine hungwaru nzira dzekubatsira kuvandudza kugadzirwa uye mashandiro edanho rechiteshi chemagetsi uye kuwedzera kugadzirwa kwemagetsi.
