光伏(fu)直驅技(ji)術、五大運(yun)行模式(shi)、分布式(shi)自發多用、三元(yuan)換流技(ji)術、綠色(se)變(bian)頻技(ji)術
光伏發電(dian)(dian)系統(tong)不發電(dian)(dian)，主機(ji)向電(dian)(dian)網取電(dian)(dian)運(yun)行，機(ji)組(zu)相(xiang)當(dang)于(yu)常規高效變頻離心機(ji)。
主機(ji)不(bu)工作(zuo)，光伏(fu)發(fa)(fa)電(dian)(dian)系(xi)統(tong)所(suo)發(fa)(fa)電(dian)(dian)能全部(bu)向電(dian)(dian)網送電(dian)(dian)，機(ji)組提供光伏(fu)逆變器功能，系(xi)統(tong)相(xiang)當于一個(ge)常(chang)規光伏(fu)發(fa)(fa)電(dian)(dian)站。
當光(guang)伏發(fa)(fa)(fa)電功率(lv)(lv)等于主(zhu)機耗電功率(lv)(lv)時，光(guang)伏系統(tong)所發(fa)(fa)(fa)電能(neng)全部用于主(zhu)機耗電，光(guang)伏發(fa)(fa)(fa)電系統(tong)所發(fa)(fa)(fa)電能(neng)完(wan)全自發(fa)(fa)(fa)自用，對外“零(ling)耗電”。
當光伏發電(dian)(dian)功率大于主機耗(hao)電(dian)(dian)功率時，光伏發電(dian)(dian)系統(tong)所發電(dian)(dian)能(neng)部分(fen)用于主機耗(hao)電(dian)(dian)，剩余部分(fen)輸向電(dian)(dian)網。
當(dang)光伏(fu)發電(dian)(dian)功率(lv)小于主機耗電(dian)(dian)功率(lv)時，光伏(fu)發電(dian)(dian)系統所(suo)發電(dian)(dian)能不足以驅動(dong)主機工作，需(xu)要從電(dian)(dian)網補充部(bu)分電(dian)(dian)能。
光伏直驅利用(yong)率達99%，比(bi)常規(gui)發電(dian)(dian)并網+空調系統用(yong)電(dian)(dian)模式提升效率6%-8%，發用(yong)電(dian)(dian)動態切換時(shi)間小于10ms，被廣東省科(ke)學技術(shu)廳鑒定(ding)委員會(hui)鑒定(ding)為“國(guo)際領先”。
