Yintoni eyona ndawo iphezulu yokuJonga uMbane kwiMguquli yeMpompo yaManzi yeSola?
Amandla aphezulu okulandelela i-MPPT ibhekisela ekubeni i-inverter ilungisa amandla okuphuma kwe-photovoltaic array ngokweempawu zeqondo lokushisa elihlukeneyo kunye nokukhanya kokukhanya, ukwenzela ukuba uluhlu lwe-photovoltaic luhlala luvelisa amandla aphezulu.
Yenza ntoni iMPPT?
Ngenxa yempembelelo yezinto zangaphandle ezifana nokukhanya kokukhanya kunye nokusingqongileyo, amandla okukhutshwa kweeseli zelanga atshintshiwe, kwaye umbane okhutshwe ngamandla okukhanya ungaphezulu.I-inverter eneMPPT yokulandelela amandla aphezulu kukusebenzisa ngokupheleleyo iiseli zelanga ukuze ziqhube kwindawo ephezulu yamandla.Oko kukuthi, phantsi kweemeko zokukhanya kwelanga rhoqo, amandla okukhutshwa emva kwe-MPPT aya kuba phezulu kunokuba phambi kwe-MPPT, eyindima yeMPPT.
Ngokomzekelo, cinga ukuba i-MPPT ayikaqali ukulandelela, xa i-voltage ephumayo yecandelo yi-500V.Emva koko, emva kokuba i-MPPT iqale ukulandelela, iqala ukulungelelanisa ukuchasana kwisekethe ngokusebenzisa isakhiwo sesiphaluka sangaphakathi ukuguqula i-voltage yemveliso yecandelo kwaye utshintshe imveliso yangoku de amandla aphumayo aphezulu (masithi yi-550V ephezulu), kwaye emva koko igcina umkhondo.Ngaloo ndlela, oko kukuthi, phantsi kweemeko zokukhanya kwelanga rhoqo, amandla okukhutshwa kwecandelo kwi-voltage ye-550V yokuphuma iya kuba phezulu kune-500V, eyindima yeMPPT.
Ngokuqhelekileyo, impembelelo ye-irradiance kunye nokutshintsha kweqondo lokushisa kumandla ophumayo ibonakala ngokuthe ngqo kwi-MPPT, oko kukuthi, i-irradiance kunye nobushushu zizinto ezibalulekileyo ezichaphazela i-MPPT.
Ngokuhla kwe-irradiance, amandla okuphuma kweemodyuli ze-photovoltaic aya kuncitshiswa.Ngokunyuka kweqondo lokushisa, amandla okuphuma kweemodyuli ze-photovoltaic aya kuncipha.
I-Inverter ubuninzi bokulandelela indawo yamandla (MPPT) kukufumana eyona ndawo iphezulu yamandla kumzobo ongentla.Njengoko kunokubonwa kulo mzobo ungasentla, eyona ndawo iphezulu yamandla iyancipha ngokulinganayo njengoko i-irradiance iyancipha.
Ngophuhliso lobuchwepheshe be-elektroniki, ulawulo lweMPPT lwangoku lwezixhobo zelanga lugqitywa ngokubanzi yi-DC/DC yokuguqulwa kwesekethe.Umzobo weskim uboniswe ngezantsi.
Uluhlu lweeseli ze-photovoltaic kunye nomthwalo uxhunyiwe ngesekethe ye-DC / DC.Isixhobo esiphezulu sokulandelela amandla sihlala sibona utshintsho lwangoku kunye ne-voltage ye-photovoltaic array, kwaye ilungelelanise umlinganiselo we-PWM wokuqhuba umqondiso we-converter ye-DC / DC ngokweenguqu.
Impompo yamanzi elangainverteryenzelwe kwaye yaphuhliswa yi-Xi 'i-Noker Electric isebenzisa iteknoloji ye-MPPT, isebenzisa ngokufanelekileyo iphaneli yelanga, i-algorithm yolawulo oluphezulu, ukusebenza okuzinzileyo kunye nokuthembekileyo, yimveliso ecetyiswayo kakhulu.
