I-voltage kwicala le-DC lenkqubo yelanga inyuka yaya kwi-1500v, kwaye ukukhuthaza nokusetyenziswa kweeseli ezingama-210 zibeka phambili iimfuno zophuhliso lwe-fotovolstaic. Emva kokuba i-voltage yenkqubo inyuswe, ikhupha imiceli mngeni kwi-insumpas kunye nokhuseleko lwenkqubo, kwaye inyuse umngcipheko wokuqhekeka, kunye nesekethe yangaphakathi. Iimpazamo ezihambelana noko zenzeka.
Ukuze ihambelane namacandelo akwandisiweyo, abavelisi be-inverter banyusa igalelo langoku lomtya ukusuka kwi-20a ukuya kwi-20A -.Umvelisi wegalelo langoku, umenzi we-Inverter oye walungisa uyilo lwangaphakathi lwe-MPPP kwaye lwandise amandla okufikelela I-MPTPT ukuya kwezintathu okanye ngaphezulu Ukusombulula le ngxaki, i-DC switch enomsebenzi "we-DC ekrelekrele we-DC" ivele njengoko amaxesha ayifunayo.
01 Umahluko phakathi kokuSupotha ngokwesiko kunye nokutshintsha kwe-DC
Okokuqala, ukutshintshwa kwe-DC yendabuko inokuqhekeka ngaphakathi kwexesha le-15a, emva koko kunokwaphula i-voltage ye-15a kwaye ungene ngaphakathi. , ihlala ingakwazi ukwaphula isiphaluka esifutshane okwangoku.
Owona mahluko mkhulu phakathi kokutshintsha kweswiti kunye nomqhekezi wesekethe kukuba umtyholi wesekethe unokwaphula isiphaluka esifutshane, kwaye isekethe emfutshane ngoku kwimeko yesiphoso esikhulu kunophawu lwesekethe ; Ukusukela kwisekethe nje ifutshane ye-Photovoltaic kwicala le-DC lihlala malunga ne-1.2 amaxesha okuqhutywa ngoku, ezinye izinto zokutshintsha okanye ukutshintshela kwi-Switches ikwanokuqhekeza icala le-DC.
Okwangoku, i-Smart DC Switter esetyenziswe yi-Inverter, ukongeza ekuhlangabezeni i-IEC60943 i-IEC60947, ikwahlukane netyala eligqithileyo lokwaphula indleko isombulula ingxaki yomtya wangoku. Kwangelo xesha, utshintsho lwe-DC lwe-DC ludityaniswe ne-DSP ye-ingerter, ukuze iyunithi yohambo inokuthi iqonde ngokuchanekileyo kwaye ngokukhawuleza iqaphele imisebenzi enjengokhuselo olugqithisileyo kunye nokukhusela kwisekethe.
Umzobo wombane we-Smart DC
I-02 yenkqubo yelanga ifuna ukuba xa inani lamajelo afakiweyo emityalweyo phantsi kwe-MPTP nganye ngu-MPTP ngu-MPPT ngu-DC. Umsebenzi kunye nolondolozo lomsebenzi wokutshintshwa rhoqo kwe-fuse kwi-DC. I-Interters Sebenzisa i-DC i-DC Switches endaweni ye-fuse. I-MPTP inokufaka amaqela ama-3 omtya. Phantsi kweemeko ezigwenxa kakhulu, kuya kubakho umngcipheko wokuba amaqela ama-2 akhoyo aya kuvela kwiqela eli-1 lemitya. Ngeli xesha, utshintsho lwe-DC olukrelekrele luya kuvula i-DC Switch ngokusebenzisa ukukhululwa kwe-shint kwaye ikhuphe ngexesha. isekethe yokuqinisekisa ukususwa kweziphoso.
Umzobo we-Schept ye-MPPPT yomtya wangoku
Ukukhutshwa kwe-shint ngokuyintloko ilahleko kunye nesixhobo sokuhamba, esisebenza kwi-volmuge echaziweyo kwi-SHICS, kunye nezenzo ezinjenge-Electromagnetic Trake, kunye ne-shippiking ivuliwe ihlala isetyenziswa kulawulo lwe-InHe-Off-Off Smart DC Switter ilungiselelwe kwi-Initter ye-One-Inaverter, i-DC Switch ingakhutshwa kwaye ivulwe kwisekethe i-DC ukuba ikhuphe isekethe ye-DC.
Ku-Abwer usebenzisa umsebenzi wokukhusela uhambo lwe-SHunt, kuqala kufuneka inyanzelise ukuba i-Sunt yeLant Clail ifumana amandla oKhuseleko ngaphambi kokuba isebenze ngayo umsebenzi ophambili wesekethe onokuthi aqinisekiswe.
03 IXESHA LOKUSETYENZISWA KWEXESHA LOKUGQIBELA
Njengoko ukhuseleko lwe-Photovoltaic Plane fumana ingqwalaselo ngakumbi, imisebenzi yokhuseleko enje nge-ASCI kunye ne-RSD sele ikhankanyiwe ngakumbi kwaye kutsha nje.SMart DC. Xa kwenzeke impazamo, i-Smart DC itshintshe ngokufanelekileyo kulawulo olukuyo kunye nolawulo olupheleleyo lwe-smart switch switch. Emva kwentshukumo ye-Afci okanye i-RSD, i-DSP iya kuthumela umqondiso wokuhamba ukuze uhambise ngokuzenzekelayo i-DC DC ye-DC. Yenza indawo yeqonga ecacileyo yokuqinisekisa ukhuseleko lwabasebenzi bolondolozo. Xa i-DC ye-DC iqhekeza enkulu yangoku, iya kuchaphazela ubomi bombane bokutshintsha. Xa usebenzisa i-DC ye-DC ye-DC, ukwaphula kuphela kutya ubomi boomatshini bokutshintsha kwe-DC, ekhusela ngokufanelekileyo ubomi bombane kunye nokucima i-Arc swiption ye-DC.
Ukusetyenziswa kwe-DC ye-DC ye-DC ye-DC yenza ukuba kwenzeke ukuba ikwazi ukuthembeka "Ukuvalwa kweqhosha" le-inverter kwimbonakalo yolawulo lwe-DSP; I-DC Supction ye-Inverter ingakhawuleza kwaye Ngokuchanekileyo ivaliwe nge-DSP isiphawuli, esenza indawo enokuthenjwa yokusebenza.
Isishwankathelo se-04
Ukusetyenziswa kwe-DC ye-DC ye-DC icombulula ingxaki yokukhuselwa kwemali eyamkelweyo, kodwa nokuba umsebenzi wokuhamba okude kunye nolondolozo lwendlela yokufumana ukusebenza kunye nolondolozo kunye nokuphucula ukhuseleko lwabasebenzisi kwiimeko zonyango. Ukukwazi ukujongana neempazamo kukufuna isicelo kunye nokuqinisekiswa kweS-SMART DC kwishishini.
IXESHA LOKUQALA: NgoFebruwari-16 ukuya ku-2003
