Abalawuli bentlawulo yeMPPTokanyeUbuninzi boMkhondo waMandla oMbaneAbalawuli beTyala luhlobo lwabalawuli bentlawulo abalandelela amandla kwindawo ephezulu yamandla.
Yintoni isiLawuli seNtlawulo yeMPPT?
Umlawuli wentlawulo yeMPPT uqinisekisa ukuba imithwalo iyayifumanaubuninzi bangokuukuba isetyenziswe (ngokutshaja ibhetri ngokukhawuleza). Elona nqanaba lamandla linokuqondwa njengesixhoboamandla ombane afanelekileyoapho amandla aphezulu anikezelwa kwimithwalo, ngeilahleko encinci.Oku kukwabizwa ngokuqhelekileyo njengeamandla ombane aphezulu.
Yintoni eyona ndawo iphezulu yamandla (MPP)?
Ieyona ndawo iphezulu yamandla (MPP)ichaza inqaku kumbane wangoku (IV) igophe apho isixhobo sePV selanga sivelisa eyona mveliso inkulu, okt apho imveliso yamandla akhoyo (I) kunye nombane (V) iphezulu. I-MPP inokutshintsha ngenxa yezinto zangaphandle ezifana nobushushu. , iimeko zokukhanya kunye nokusebenza kwesixhobo.Ukuze kuqinisekiswe ukukhutshwa kwamandla aphezulu (i-Pmax) yesixhobo se-PV yelanga ngokujonga le miba yangaphandle,Awona mandla aphezulu eetraki zemveliso (MPPT)inokusetyenziselwa ukulawula ukuxhathisa kwesixhobo.
Basebenza njani abalawuli bentlawulo yeMPPT?
Nabani na oqheleneyo neempawu zokutshaja nokukhupha ibhetri uqhelene nento yokuba amandla ombane ebhetri ayahluka kumxholo wokutshaja.Njengoko umpompoza ngoku ukusuka kumandla aphezulu ukuya kwisakhono esiphantsi, kokukhona uqina umsinga okanye umahluko wombane. iukuhamba kwangoku.Olu lwakhiwo lunokubakho lunokwenziwa umnqantsa ngeendlela ezimbini:
1. Ngokwandisa amandla ombane emveliso yeSolar Panel
2. Ngokunciphisa amandla ombane ebhetri (ukukhupha ibhetri)
Umlawuli-Awona manqaku aphezulu[/caption]
Ukusebenzisa i-voltage yepaneli eyandisiweyo ukuhambisa amandla aphezulu
Ngoku iibhetri zinokuhlawuliswa kuphela ukuba umbane ophumayo wepaneli yelanga mkhulu kuneebhetri, ukuququzelela ukuhamba kwangoku ukusuka kwiphaneli ukuya kwibhetri. iradiance).Ngemini enelanga amandla ombane aphumayo anokuba phezulu kunokorated imveliso yombane, ngelixa ngexesha losuku lwamafu i-voltage ephumayo mhlawumbi ingaphantsi.Abalawuli abaqhelekileyo abanawo amandla okusebenzisa lo mbane ophezulu wokukhupha amandla ukuhambisa amandla amaninzi.Nangona kunjalo abalawuli bentlawulo yeMPPT banakho ukulungisa umbaneukuze ufumane ukunyuswa kwangoku ngexesha leemfuno zepeak.MPPT ihambisa phezulu kunentlawulo elinganisiweyo kwibhetri njengoko ikwazi ukulungelelanisa umbane kumlinganiselo wangoku.
Ukusebenzisa amandla ombane ebhetri ukuhambisa amandla aphezulu
Okwangoku kunye neVoltage zihambelana ngokungafaniyo enye kwenye.Ngamanye amagama, ukuba ukunyuka kwangoku, i-voltage yehla kunye ne-vice versa.Ngokunciphisa i-current ngokuzisa ukuchasana kwindlela yangoku, umlawuli wentlawulo ye-MPPT unokunyusa umbane.Okuumlinganiselo wombane kumlinganiselo wangokuUlungelelwaniso lubizwa ngokuba Ubuninzi bokulandelela indawo yamandla.I-MPPT yonyusa ibhetri ekhoyo malunga ne-25% ukuya kwi-30%.Okubalulekileyo ukugcina engqondweni kukuba i-80% yebhetri ekhutshiweyo iya kuthi.ukuhlawulisa ngokukhawulezangaphezu kwe-50% yebhetri ekhutshweyo. Isizathu salokhu kukuba xa ibhetri iqala ukukhupha, i-voltage yayo iyancipha.Imkhulu umsantsaphakathi kombane ophumayo wepaneli yelanga kunye nombane webhetri, kokukhona okukhona kuya kuqukuqela kwibhetri, kwaye ibhetri iya kuhlawuliswa ngokukhawuleza.
Iindlela ezidityanisiweyo zokutshaja ibhetri ngokupheleleyo
Abalawuli bentlawulo yeMPPT basebenzisa yomibini imigaqo ekhankanywe ngasentla ukuhambisa ubuninzi bamandla.ii-set-points ezihlengahlengiswayoenokuthi ihlelwe kwaye ilungelelaniswe ngokweemfuno zakho.Ukuba ufuna ukukhetha phakathi komgangatho kunye nomlawuli wentlawulo weMPPT, ngokuqhelekileyo uhlawula kancinane umlawuli ofanelekileyo weMPPT yindlela yokuhamba.
