Grid-Yakabatanidzwa Kurongeka uye Chengetedzo Chengetedzo yeSolar PV Inverters

Hurumende nemakambani emagetsi pasi rese anotarisira kuti photovoltaic simba rekugadzira richaita basa rakakosha mune ramangwana rekupa simba. Kushandura yakananga ikozvino (DC) inogadzirwa nemaseru ezuva kuita alternating yazvino (AC) iyo inokwanisa kusanganisa zvisina mutsetse mugedhi haingori dambudziko rehunyanzvi asiwo zvinoisa zvinoomesesa kune vanogadzira. PV inverters inofanirwa kuwana hunyanzvi hwekuita munzvimbo dzakasiyana siyana dzekubuda kwemagetsi uye nharaunda dzekushanda uku uchinyatso kuomerera kumazinga ekuchengetedza.

Kurongeka uye Kufunga Kwekugadzira

Photovoltaic inverter dhizaini inofanirwa kukoshesa shanduko yesimba inoshanda uku uchichengetedza kuchengetedzwa kwehurongwa. Chaiyo simba kuyerwa chinhu chakakosha mukusimudzira inverter kuita. Kutsigira mafambiro ari kuitika muphotovoltaic tekinoroji, vanogadzira inverter vanofanirwa kushandirapamwe nevagadziri vema sensor kuti vagadzire pamwe chete zvigadzirwa zvinosangana nezvichangoburwa zvinodiwa.

Kuvandudza Simba Rekugadzira Kubudirira

Kuvhura kugona kwakazara kwePV masisitimu, kuedza kunofanirwa kutarisisa kuvandudza kugadzirwa kwemagetsi kudzikisa mutengo. Parizvino, vagadziri vemasero ezuva vari kuedza kuwedzera mwenje-kune-magetsi shanduko kushanda zvakanaka, nepo PV inverter vagadziri vanotarisisa mukugadzira inotevera-chizvarwa inverters inobatanidza diagnostics uye humwe hungwaru maficha ekuwedzera simba nekubudirira. Multi-tambo tekinoroji inomiririra iri kubuda, inoita kuti tambo yega yega ive neyakazvimiririra yeMaximum Power Point Tracking (MPPT) mudziyo, nekudaro ichiwedzera kubuda kwesimba.

Zvokuchengetedza Maitiro

Nepo dhizaini isina dhizaini inobatsira kudzikisa mitengo uye kugadzirisa mashandiro, ivo vanounzawo mamwe matambudziko ekuchengetedza. Semuenzaniso, inverter inobuda inogona kunge iine zvikamu zveDC nekuda kwezvinhu zvakaita senge IGBT inochinja. Naizvozvo, chaiwo masensa azvino anofanirwa kuverengerwa panguva yekugadzira kudzikisa kudzika uye kukukurwa, kuve nechokwadi chekutevedzera akaomesesa DC jekiseni miganho munyika dzese. Pamusoro pezvo, kudzivirira kudonha kwevhu kwakakosha, kunowanzo kuwanikwa uchishandisa zvakasara zvigadziriso (RCDs) kana zvakafanana sensor mhinduro kuchengetedza sisitimu.

Sezvo tekinoroji ichifambira mberi, photovoltaic inverter dhizaini dhizaini inotarisirwa kuwedzera kuomarara. Semuyenzaniso, miganho yakabvumiranwa pasi rose pane yakazara harmonic distortion (THD) ye inverter inobuda migero inogona kubuda. Izvi zvinoda kuyerwa kwazvino kunyangwe pamafrequency akakwira zvakanyanya kupfuura akajairwa grid frequencies. Kusimbisa kubatana pakati pevagadziri veinverter uye vagadziri ve sensor vanogona kuisa hwaro hwehunyanzvi hwekuvandudza tekinoroji, nekudaro kuchengetedza mupendero wemakwikwi muindasitiri yesolar inokurumidza kubuda.

Muchidimbu, yakatarisana nemusika wezuva uri kukura, dhizaini yephotovoltaic inverters haifanire kungoteedzera kushanda kwepamusoro asi zvakare kuve nechokwadi chekuchengetedzwa kwakakwana. Kuburikidza nekuenderera mberi kwehunyanzvi hwekuvandudza tekinoroji uye kushamwaridzana kweindasitiri yepedyo, tinogona kutarisira kuona akangwara, akavimbika, uye anoshanda zvakanyanya photovoltaic inverters achibuda.
