Inkqubo yeprojekthi kufuneka isebenzise imida yokusebenza evunyiweyo yemodeli enikiweyo kunye nayo nayiphi na amaxwebhu okuthotywa kwamandla ajoliswe kule projekthi. Olo lwazi lwenza ukuba ingxelo yokwamkelwa kombane ihlale idityaniswe neemeko zovavanyo zokwenene.
Yintoni uvavanyo lokwamkelwa komgangatho wamandla lwe-BESS?
Uvavanyo lokwamkelwa lomgangatho wamandla lwe-BESS yinkqubo yokuqalisa elawulwayo ethelekisa ukusebenza kombane okulinganisiweyo kumda we-AC ovunyelwene ngawo nemigangatho emisiweyo yeprojekthi. Ngokuqhelekileyo iquka impendulo yefactor yamandla, ukubekwa phambili kwe-P/Q, idatha ye-harmonic kunye neerekhodi ezixhasayo zemitha, izilawuli kunye neziganeko. Le nkqubo isayiniweyo ichaza iimeko zokusebenza kunye nothelekiso lokwamkelwa.
Yeyiphi idatha ekufuneka irekhodwe ngexesha lovavanyo lomgangatho wamandla e-BESS?
Ngenisa indawo ye-PCC, isazisi semitha, useto lwe-analyzer, umthombo wexesha, ivoltage, i-current, i-frequency, i-kW, i-kvar, i-kVA, i-power factor kunye nedatha ye-harmonic efunekayo kwiprojekthi. Yongeza imo yokusebenza ye-BESS, umyalelo we-PCC, impendulo elinganisiweyo, i-SOC, umda okhutheleyo, imeko yomthwalo wesiza kunye nayo nayiphi na irekhodi le-alam okanye lokuphambuka. Gcina idatha ekrwada ethunyelweyo kunye nengxelo esayiniweyo.
Yintoni umnini ekufuneka ayivume phambi kokuqaliswa kokusebenza kwe-BESS malunga nomgangatho wamandla?
Vuma imida yokulinganisa, isalathiso sedayagramu yomgca omnye, ulungiselelo lwezixhobo zovavanyo, iimeko zokusebenza, imiyalelo yamandla kunye namandla asabela, uphahla lwe-P/Q, indlela ye-harmonic, imigqaliselo yokwamkelwa, iindima zabangqina, indlela yokugcina idatha kunye nenkqubo yokuphambuka. Oku kuvunywa kunika i-EPC kunye nomthengisi isiseko esinye esicacileyo sokwenza uvavanyo lwasenkundleni nokulungiselela ingxelo yokunikezela.
