Iyini I-Maximum Power Point Tracking Ku-Solar Water Pump Inverter?

Iyini I-Maximum Power Point Tracking Ku-Solar Water Pump Inverter?

I-MPPT yokulandelela indawo yamandla aphezulu isho ukuthi isiguquli silungisa amandla okukhipha ohlelo lwe-photovoltaic ngokwezimpawu zezinga lokushisa elihlukile le-ambient nokuqina kokukhanya, ukuze uhlelo lwe-photovoltaic luhlale lukhipha amandla amakhulu.

Yenzani i-MPPT?

Ngenxa yethonya lezici zangaphandle ezifana nokuqina kokukhanya nendawo ezungezile, amandla okukhipha amaseli elanga ayashintshwa, futhi ugesi okhishwa amandla okukhanya uyanda.I-inverter ene-MPPT yokulandelela amandla aphezulu iwukusebenzisa ngokugcwele amaseli elanga ukuze asebenze endaweni yamandla aphezulu.Okusho ukuthi, ngaphansi kwesimo semisebe yelanga ehlala njalo, amandla okukhipha ngemva kwe-MPPT azoba ngaphezu kwalokho ngaphambi kwe-MPPT, okuyindima ye-MPPT.

Isibonelo, cabanga ukuthi i-MPPT ayikaqali ukulandelela, lapho i-voltage ephumayo yengxenye ingu-500V.Khona-ke, ngemva kokuba i-MPPT iqale ukulandelela, iqala ukulungisa ukumelana kumjikelezo ngokusebenzisa isakhiwo sesifunda sangaphakathi ukuze ushintshe i-voltage ephumayo yengxenye futhi ushintshe ukukhishwa kwamanje kuze kube yilapho amandla okukhiphayo engaphezulu (ake sithi yi-550V esiphezulu), futhi bese ilokhu ilandelela.Ngale ndlela, okusho ukuthi, ngaphansi kwesimo semisebe yelanga ehlala njalo, amandla okukhipha ingxenye ku-voltage yokuphuma kwe-550V azoba phezulu kunalokho ku-500V, okuyindima ye-MPPT.
Ngokuvamile, ithonya le-irradiance kanye nezinguquko zokushisa kumandla okukhiphayo kubonakala ngokuqondile ku-MPPT, okusho ukuthi, i-irradiance kanye nezinga lokushisa yizici ezibalulekile ezithinta i-MPPT.

Ngokuncipha kwe-irradiance, amandla okukhipha amamojula we-photovoltaic azoncishiswa.Ngokunyuka kwezinga lokushisa, amandla okukhipha amamojula we-photovoltaic azokwehla.

I-Inverter maximum power point tracking (MPPT) iwukuthola indawo enkulu yamandla esithombeni esingenhla.Njengoba kungabonwa emfanekisweni ongenhla, iphoyinti lamandla eliphakeme liyancipha cishe ngokulinganayo njengoba i-irradiance iyancipha.

Ngokuthuthukiswa kobuchwepheshe be-elekthronikhi, ukulawulwa kwamanje kwe-MPPT kwezinhlelo zelanga ngokuvamile kuqedwa yisekethe yokuguqulwa kwe-DC/DC.Umdwebo wohlelo ukhonjiswe ngezansi.

I-photovoltaic cell array kanye nomthwalo kuxhunywe ngesekethe ye-DC/DC.Idivayisi yokulandelela amandla amaningi ihlale ithola izinguquko zamanje kanye ne-voltage ye-photovoltaic array, futhi ilungisa isilinganiso se-PWM yesignali yokushayela yesiguquli se-DC/DC ngokuvumelana nezinguquko.

Iphampu lamanzi elangai-inverteriklanywe futhi yathuthukiswa ngu-Xi 'an Noker Electric isebenzisa ubuchwepheshe be-MPPT, isebenzisa ngokuphumelelayo iphaneli yelanga, i-algorithm yokulawula ethuthukisiwe, ukusebenza okuzinzile nokuthembekile, kuwumkhiqizo onconywa kakhulu.
