Yintoni i-MPTP kunye ne-MPTP ye-hybrid yenverter?

Ukusebenza kwezityalo zamandla ePhotovoltaic, sihlala sinethemba lokwandisa ukuguqulwa kwamandla okukhanya kumandla ombane ukuze kugcine iimeko ezifanelekileyo zomsebenzi. Ke, sinokunyusa njani amandla okuvelisa amandla kwizityalo zamandla eFotovoltaic?

Namhlanje, masithethe malunga nento ebalulekileyo echaphazela amandla okuvelisa amandla ePhotvoltaic yezityalo zamandla - itekhnoloji yokulandela umkhondo wamandla, yiyo le nto siyibizaI-MPTP.

Eyona nkqubo iphambili yokulandela umkhondo wenqaku (i-MPTPT) yenkqubo yombane ivumela iphaneli ye-photovoltaic ukukhupha amandla ombane ngokuhlengahlengisa imeko yokusebenza kwemodyuli yombane. Ingayigcina ngokufanelekileyo indawo ethe ngqo eveliswe yiphaneli yelanga kwibhetri, kwaye inokusombulula ngokufanelekileyo ukusetyenziswa kwamandla kunye nemizi mveliso kwiindawo ezikumgangatho kunye nemizi mveliso kwiindawo ezikude kunye neendawo zokhenketho ezingenakugutyungelwa ziigridi zendalo, ngaphandle kongcoliseko lwendalo.

Umlawuli we-MPTP unokufumana i-volmuge evelisiweyo yephaneli ye-solar ngexesha le-voltage ephezulu kunye nexabiso langoku (vi) ukuze inkqubo ihlawulise ibhetri ngeyona ndlela iphambili. Isetyenziswe kwiinkqubo zeSolar Photostaic, ukulungelelanisa umsebenzi weephaneli zesolar, iibhetri, kunye nemithwalo yingqondo yendlela yefotovoltaic.

Indima ye-MPTP

Umsebenzi we-MPTP unokuvezwa kwisivakalisi esinye: amandla okukhutshelwa kweseli yefotovoltaic inxulumene neflogi yokusebenza ye-MPTP. Kuphela kuxa isebenza kwi-voltage efanelekileyo kakhulu kunokuba amandla awo okukhupha anexabiso elikhethekileyo.

Kuba iiseli zelanga zichaphazeleka zizinto zangaphandle ezifana nobunzulu bokukhanya kunye nokusingqongileyo, ukutshintsha amandla abo, kwaye ubukhali bokukhanya kuvelisa umbane ngakumbi. I-inverter ene-MPTP ephezulu yokulandela umkhondo wamandla kukusebenzisa ngokupheleleyo iiseli zelanga kwaye kubenza baqhube kwinqanaba eliphezulu lamandla. Oko kukuthi, phantsi kwemeko yemitha yelanga rhoqo, amandla okukhupha emva kokuba i-MPPP iya kuba iphakame ngaphezu kwalonto ngaphambi kokuba i-MPTP.

I-MPTP yokulawula ifezekiswa ngokubanzi ngesekethe ye-DC / DC, uluhlu lwe-photovoltaic sels iqhagamshelwe kumthwalo ngesekethe i-DC / DC, kwaye eyona fowuni iphezulu yokulandela umkhondo ihlala iphezulu

Fumana utshintsho lwangoku kunye ne-voltage yeefotovoltaic uluhlu, kwaye uhlengahlengise umjikelo we-PWM umqondiso we-DC / DC ngotshintsho.

Kwisekethe elinemigca, xa ukuchasana komthwalo kulingana nokuchasana kwangaphakathi kokunikezelwa kwamandla, ukuhambisa amandla kuneyona nto iphambili yamandla. Nangona zombini iiseli zefotovoltaic kunye ne-DC / i-DC yokuguqula zinamandla, zinokuthathwa njengeziphaluka ezimfutshane ngexesha elifutshane kakhulu. Ke ngoko, ukuba nje ukunyangeka okulinganayo kwesekethe yeDC-DC kuyalungiswa kangangokuba ihlala ilingana nokungaxhathisi kwangaphakathi kweseli yefoto, kwaye i-MPPP yeseli ye-Photovoltaic inokufezekiswa.

Ilayini, nangona kunjalo, lifutshane kakhulu, linokuthathwa njengesekethe elayini. Ke ngoko, ixesha elide njengokulingana kwesekethelwano lwe-DC-DC lihlengahlengiswa ukuze lilingane nefotovoltaic

Ukuxhathisa kwebhetri kungakuqaphela iziphumo eziphambili zeseli yefotovoltaic kwaye ikwaqonda i-MPPP yeseli yefotovoltaic.

Ukusetyenziswa kwe-MPTP

Ngokuphathelele isikhundla se-MPTP, abantu abaninzi baya kuba nemibuzo: kuba i-MPTP ibaluleke kangaka, kutheni singayiboni ngokuthe ngqo?

Ngokwenyani, i-MPPP idityaniswe kwi-inverter. Ukuthatha i-micromifoverter njengomzekelo, inqanaba lemodyuli ye-MPTP ye-MPTP ye-track inqaku eliphezulu lemodyuli ye-PV nganye nganye. Oku kuthetha ukuba nokuba imodyuli yefotovoltaic ayisebenzi, ayiyi kuchaphazela amandla okuvelisa amandla ezinye iimodyuli. Umzekelo, kuyo yonke inkqubo yefotovoltaic, ukuba imodyuli enye ivinjelwe ngama-50% ukukhanya kwelanga, olonalawulo lwendlela ephezulu yamandla kwezinye iimodyuli ziya kuqhubeka nokugcina impumelelo yabo ephezulu yokuvelisa.

Ukuba unomdla kwiI-MPTP ye-hybrid yenverteryamkelekile ukuba uqhagamshelane ne-Potvoltaic DerailinceFunda ngokugqithisileyo.
