Ngohlelo oluxhunywe yi-solar, isikhathi nesimo sezulu kuzobangela izinguquko emisebeni yelanga, futhi i-voltage endaweni yamandla izoshintsha njalo. Ukuze wandise inani likagesi elenziwe, liqinisekiswa ukuthi amaphaneli elanga angahanjiswa ngokukhishwa okuphezulu kakhulu lapho ilanga libuthakathaka futhi liqinile. Amandla, imvamisa uhlelo lokukhuphula lungezwa kwi-inverter ukunweba amavolula endaweni yalo yokusebenza.
Uchungechunge olulula olulandelayo luyachaza ukuthi kungani kufanele usebenzise ukukhulisa ukukhulisa, futhi kukhulisa uhlelo olukhulisa khona kungasiza uhlelo lwamandla elanga ukukhulisa amandla kagesi.
Kungani Kukhulisa Ukukhulisa Umjikelezo?
Okokuqala, ake sibheke uhlelo olujwayelekile lwe-Inverter emakethe. Siqukethe umjikelezo wokukhulisa umjikelezo kanye nomjikelezo we-inverter. I-Middle ixhunyiwe ngebhasi le-DC.
Isifunda se-Inverter sidinga ukusebenza kahle. Ibhasi le-DC kumele libe liphakeme kune-Grid Voltage Peak (uhlelo lwesigaba ezintathu luphakeme kunenani eliphakeme le-Line Voltage), ukuze amandla akwazi ukuphuma kugridi phambili. Imvamisa yokusebenza kahle, ibhasi le-DC livame ukuguquka nge-grid voltage. , ukuqinisekisa ukuthi iphakeme kunegridi yamandla.
Uma i-voltage yephaneli iphakeme kune-voltage edingekayo yebhasi, i-inverter izosebenza ngokuqondile, futhi i-voltage voltage izoqhubeka nokulandela iphuzu eliphakeme. Kodwa-ke, ngemuva kokufinyelela emfunekweni ye-voltage ephansi, ayikwazi ukwehliswa okunye, futhi iphuzu eliphezulu lokusebenza kahle alikwazi ukutholwa. Ububanzi be-MPPT buphansi kakhulu, okunciphisa kakhulu ukusebenziseka kosizo lwamandla futhi inzuzo yomsebenzisi ayinakuqinisekiswa. Ngakho-ke kumele kube nendlela yokwenza lokhu ukushiyeka, futhi onjiniyela basebenzisa umjikelezo wokuqinisa amandla ukufeza lokhu.
Kukhuthaza kanjani ukukhulisa umkhawulo we-MPPT ukukhulisa ukukhiqizwa kwamandla?
Lapho i-voltage yephaneli iphakeme kune-voltage edingwa yibhasi, amandla okuthuthukisa asesimweni sokuphumula, amandla alethwa kwi-inverter nge-didoode yayo, futhi i-inverter iqeda ukulandelwa kwe-MPPT. Ngemuva kokufinyelela ama-voltage adingekayo eBhisbar, i-inverter ayikwazi ukuthatha izintambo. I-MPPT isebenze. Ngalesi sikhathi, isigaba sokuqinisa amandla sathathwa ukulawula kwe-MPPT, salandela i-MPPT, futhi saphakamisa ibha lebhasi ukuze liqinisekise ukuthi lizosebenza.
Ngobubanzi obubanzi be-MPPT TRACKING, uhlelo lwe-inverter lungadlala indima ebalulekile ekwandiseni amavolushi amaphaneli elanga ekuseni ekuseni, uhhafu wobusuku nezinsuku zemvula. Njengoba singabona esikrinini esingezansi, amandla wesikhathi sangempela asobala. Gqugquzela.
Kungani i-inverter enkulu yamandla ivame ukusebenzisa amasekethe wokuqinisa amandla amaningi ukukhulisa isibalo semibuthano ye-MPTT?
Isibonelo, uhlelo lwe-6kW, ngokulandelana ophahleni olungama-3KW lube ophahleni olubili, kufanele kukhethwe amalungu amabili ama-MPPT avela endaweni empumalanga, i-voltage kanye namandla aphansi, futhi i-B lise liphansi kakhulu, futhi ntambama kuphansi. Lapho kunomehluko phakathi kwama-voltages amabili, i-voltage ephansi kufanele ikhuliswe ukuze ilethe amandla ebhasini futhi iqinisekise ukuthi isebenza endaweni ephezulu yamandla.
Isizathu esifanayo, indawo enamagquma endaweni eyinkimbinkimbi kakhulu, ilanga lizodinga i-irradiation ethe xaxa, ngakho-ke idinga ama-imperttive aphakathi aphezulu, ngakho-ke amandla ama-50kw-80kw ngokuvamile angu-3-4 mpt.
