Kwiminyaka yakutshanje, itekhnoloji yokuzala kwefoto ye-Photovlic ihambile ngokutyibilika kunye nemida, kwaye ifakwe amandla akhule ngokukhawuleza. Nangona kunjalo, isizukulwana sombane sineentsilelo ezifana nokuthintela kunye nokungalawuleki. Ngaphambi kokuba kujongwane nayo, ukufikelela ngokuthe ngqo ngqo kwigridi yamandla kuya kuzisa ifuthe elikhulu kwaye kuchaphazele ukusebenza okuzinzileyo kwegridi yamandla. . Ukongeza amakhonkco ogcino lwamandla anokwenza i-Photovoltaic isizukulwane sombane kwaye ikhutshiwe ngokuthe ngqo kwigridi, kunye nokufikelela kakhulu kwigridi akuyi kuchaphazela uzinzo lwegridi. Kunye nefotovoltaic + ukugcina amandla, inkqubo inoluhlu olubanzi lwesicelo.
Inkqubo yokuGcina ifoto, kubandakanya iimodyuli zeSolar, abalawuli,amantshontsho, iibhetri, imithwalo kunye nezinye izixhobo. Okwangoku, zininzi iindlela zobugcisa, kodwa amandla kufuneka aqokelelwe kwinqanaba elithile. Okwangoku, ubukhulu becala zii-topologies ezimbini: I-DC Coupling "i-DC Coupling" kunye ne-Ac Couplng "coupling".
I-1 dc idityaniswe
Njengoko kubonisiwe kumzobo ongezantsi, amandla e-DC oveliswe yimodyuli yefotovoltaic igcinwe kwipakethi yebhetri ngomlawuli, kwaye igridi inokubiza ibhetri nge-bidirectial didirectial datchter ye-bidirectial. Indawo yokuhlanganisana yamandla ikwibhetri ye-DC.
Umgaqo wokuSebenza we-DC Coupng: Xa inkqubo yefotovoltaic iyasebenza, i-MPTP yokulawula isetyenziselwa ukubiza ibhetri; Xa umthwalo wombane unyanzelekile, ibhetri iyakukhulula amandla, kwaye okwangoku igqitywe ngumthwalo. Inkqubo yokugcina amandla iqhagamshelwe kwigridi. Ukuba umthwalo omncinci kwaye ibhetri ihlawulisiwe ngokupheleleyo, inkqubo yefotovoltaic inokubonelela ngamandla kwigridi. Xa amandla omthwalo mkhulu kune-PV yamandla, igridi kunye ne-PV inokubonelela ngamandla kumthwalo ngaxeshanye. Kuba i-Photovoltaic Society kunye nokusetyenziswa kwamandla okuLayitha azizinzile, kuyimfuneko ukuxhomekeka kwibhetri ukulungelelanisa amandla enkqubo.
I-2 i-ac idityaniswe
Njengoko kubonisiwe kumzobo ongezantsi, othe ngqo oveliswe yimodyuli yefotovoltaic iguqulwa ibe yingcaciso ye-inverter ngoku, kwaye ikhutshelwe kwigridi. Igridi inokuhlawulisa ibhetri nge-bidirectional i-bidirectial bidirectial. Indawo yokuhlanganisana yamandla ikwisiphelo soNxibelelwano.
Umgaqo wokuSebenza we-AC Pualling: Kubandakanya inkqubo yokuhambisa amandla e-Potovltaic kunye nenkqubo yokubonelela ngebhetri. Inkqubo yefotovoltaic iqulathe uluhlu lweefotovoltaic kunye ne-grid engaphakathi; Inkqubo yebhetri iqulethe iipakethi zebhetri kunye ne-bidirectial. Ezi nkqubo zimbini zinokusebenza ngokuzimeleyo ngaphandle kokuphazamisana, okanye zinokwahlulwa kwigridi enkulu yamandla ukwenza inkqubo yegridi encinci.
Zombini i-DC Coupling kunye neCoupling ye-DC kunye ne-AC ye-AC ngoku kufuneke ngoku izisombululo, nganye nganye ineengenelo nezingalunganga. Ngokwezicelo ezahlukeneyo, khetha esona sisombululo sifanelekileyo. Oku kulandelayo luthelekiso lwezi zisombululo zibini.
I-1 yeendleko Thelekisa
I-DC Coupling ibandakanya i-inverter, i-bidirectialter engaphakathi kunye nokutshintsha kwe-windows, i-AC ye-AC ibandakanya i-Inverter-qho exhunyiwe, i-INAPIREALLL INTERT kunye neKhabhinethi yokuHanjiswa kweNtsha. Ukusuka kwimbono yeendleko, umlawuli unexabiso eliphantsi kune-interter exhunyiweyo. Ukutshintshela okutshintshiselana kuyabiza kakhulu kunekhabhathi yokuhambisa amandla kwiKhabhinethi. Inkqubo yokudibanisa i-DC ingenziwa kulawulo kunye nomatshini ohlangeneyo ongaphakathi, onokwenza iindleko zempahla kunye neendleko zokufaka. Ke ngoko, iindleko zenkqubo yokudibanisa i-DC ye-DC iphantsi kakhulu kuneso seskimu sokudibana.
Uthelekiso olu-2 lokwenza isicelo
Inkqubo yokudibanisa i-DC, umlawuli, ibhetri kunye ne-inverter ixhunyiwe kothotho, unxibelelwano lusondele, kodwa ukuguquguquka kuhluthwa. Kwinkqubo ye-AC ye-AC ye-AC, i-Inverter-qho edibeneyo, ibhetri yokugcina kunye nokuguquguquka kweBhidirectial yi-gcal, unxibelelwano aluqini, kwaye ukuguquguquka kulungile. Umzekelo, kwinkqubo esele ifakiwe yifotovoltaic, kuyimfuneko ukufaka inkqubo yokugcina amandla, kungcono ukusebenzisa i-ACP ye-AC, okoko kufakwe ibhetri kwaye ayiyi kuchaphazela inkqubo ye-bidiretaic, kwaye ayizukuchaphazela inkqubo ye-bidirestaic, kwaye Inkqubo yokuGcina amandla kumgaqo, uyilo alunalo ubudlelwane ngqo nenkqubo yefotovoltaic kwaye inokugqitywa ngokweemfuno. Ukuba yinkqubo yegridi esandula ukwenziwa, iifotovoltaics, iibhetri, kunye nentsholongwane kufuneka zenziwe ngokomthwalo womsebenzisi kunye nokusetyenziswa kwamandla, kunye nenkqubo yokudibanisa i-DC ifanelekile ngakumbi. Nangona kunjalo, amandla enkqubo yokudibanisa i-DC incinci, ngokubanzi ngaphantsi kwe-500KW, kwaye kungcono ukulawula inkqubo enkulu ngenkqubo ye-AC.
I-3 yokusebenza kakuhle
Ngokwembono yokusetyenziswa kwefotovoltaic ukusebenza kakuhle, ezi nkqubo zibini zineempawu zazo. Ukuba umsebenzisi ulayisha ngaphezulu emini kwaye ngaphantsi ebusuku, kungcono ukusebenzisa i-ACP yokuCovula. Iimodyuli zefotovoltaic zinikezela ngqo amandla kumthwalo kwi-Interter-uqhagamshelo kwigridi, kwaye ukusebenza kakuhle kunokufikelela ngaphezulu kwe-96%. Ukuba umthwalo womsebenzisi uluncinci phakathi kwemini kwaye ngaphezulu ebusuku, kunye ne-Photovoltaic amandla kufuneka agcinwe phakathi kwemini kwaye kungcono ukusebenzisa ukuhlangana kwe-DC. Imodyuli yefotovoltaic igcina umbane kwibhetri ngomlawuli, kunye nokusebenza kakuhle kunokufikelela ngaphezulu kwe-95%. Ukuba i-AC iCoupling, iifotovoltaics kufuneka ziguqulwe zibe ngamandla e-AC nge-inverter, kwaye emva koko iguqulwe ibe ngamandla e-DC ngomguquli we-bidirectial, kwaye ukusebenza kakuhle kuya kuthi ga kwi-90%.
Amenssolar'sI-N3hx Seription ye-Invers yeSigaba seNqakuInkxaso yokudibanisa kwe-AC kwaye yenzelwe ukuphucula iinkqubo zelanga. Samkela abasasazi abangaphezulu kokuzibandakanya nathi ekukhuthazeni ezi mveliso ziyintsha.
