Nheyo yekugadzira simba rezuva re photovoltaic tekinoroji inoshandura zvakananga simba rechiedza kuita simba remagetsi nekushandisa simba re photovoltaic re semiconductor interface. Chinhu chikuru chetekinoroji iyi i solar cell. Masero ezuva anoputirwa uye anodzivirirwa muzvikamu zvakatevedzana kuti aumbe solar cell module yakakura uye ozobatanidzwa ne power controller kana zvimwe zvakafanana kuti aumbe mudziyo wekugadzira simba re photovoltaic. Maitiro ese aya anonzi photovoltaic power generation system. Sisitimu yekugadzira simba re photovoltaic ine ma solar cell arrays, ma battery packs, ma charge and discharge controllers, solar photovoltaic inverters, ma combiner boxes nezvimwe zvishandiso.
Sei uchishandisa inverter mu solar photovoltaic power generation system?
Inverter mudziyo unoshandura direct current kuita alternating current. Solar cells dzinogadzira DC power muzuva, uye DC power inochengetwa mubhatiri iDC power zvakare. Zvisinei, DC power supply system ine miganhu mikuru. AC loads dzakadai se fluorescent lamps, TVs, firiji, uye electric fans muhupenyu hwezuva nezuva hazvigone kushandiswa neDC power. Kuti photovoltaic power generation ishandiswe zvakanyanya muhupenyu hwedu hwezuva nezuva, inverters dzinogona kushandura direct current kuita alternating current dzinodiwa.
Sechikamu chakakosha chekugadzira simba re photovoltaic, inverter ye photovoltaic inonyanya kushandiswa kushandura direct current inogadzirwa nema photovoltaic modules kuita alternating current. Inverter haina basa rekushandura DC-AC chete, asiwo ine basa rekuwedzera mashandiro e solar cell uye basa rekudzivirira kukanganisa kwesystem. Zvinotevera ipfupiso yemabasa e automatic operation and shutdown e photovoltaic inverter uye maximum power tracking control function.
1. Basa guru rekutevera simba repamusoro
Kubuda kwe solar cell module kunosiyana zvichienderana nekusimba kwemwaranzi yezuva uye tembiricha ye solar cell module pachayo (chip temperature). Pamusoro pezvo, sezvo solar cell module iine hunhu hwekuti voltage inoderera sezvo magetsi achiwedzera, pane nzvimbo yakakodzera yekushanda uko simba guru rinogona kuwanikwa. Kusimba kwemwaranzi yezuva kuri kuchinja, uye zviri pachena kuti nzvimbo yakakodzera yekushanda iri kuchinjawo. Zvichienderana nekuchinja uku, nzvimbo yekushanda ye solar cell module inogara iri panzvimbo yepamusoro yesimba, uye sisitimu inogara ichiwana simba guru rinobuda kubva mu solar cell module. Kudzora uku ndiko kutonga kwesimba guru rekutevera. Chinhu chikuru chema inverters ema solar power systems ndechekuti anosanganisira basa re maximum power point tracking (MPPT).
2. Kushanda otomatiki uye basa rekumisa
Mushure mekubuda kwezuva mangwanani, simba remwaranzi yezuva rinowedzera zvishoma nezvishoma, uye kubuda kwesero rezuva kunowedzerawo. Kana simba rekubuda rinodiwa neinverter rasvika, inverter inotanga kushanda yega. Mushure mekushanda, inverter inotarisa kubuda kwesero rezuva nguva dzese. Chero bedzi simba rekubuda kwesero rezuva rakakura kupfuura simba rekubuda rinodiwa kuti inverter ishande, inverter icharamba ichishanda; inomira kusvika zuva ranyura, kunyangwe paine makore uye mvura ichinaya. Inverter inogonawo kushanda. Kana kubuda kwesero rezuva kwava kudiki uye kubuda kwesero rezuva kwava pedyo ne0, inverter ichaumba mamiriro ekumira.
Pamusoro pemabasa maviri akatsanangurwa pamusoro apa, inverter ye photovoltaic inewo basa rekudzivirira kushanda kwayo yoga (ye grid-connected system), automatic voltage adjustment function (ye grid-connected system), DC detection function (ye grid-connected system), uye DC grounding detection function (ye grid-connected systems) nemamwe mabasa. Mu solar power generation system, kushanda zvakanaka kwe inverter chinhu chakakosha chinosarudza kugona kwe solar cell uye kugona kwebhatiri.
