RSVG高壓靜止無功發生器——35kV直掛SVG（水冷戶外）

榮信興業高(gao)(gao)(gao)壓(ya)(ya)無(wu)功(gong)補償裝(zhuang)置（簡稱(cheng)RSVG），采用(yong)(yong)瞬時無(wu)功(gong)功(gong)率(lv)理(li)論的(de)(de)無(wu)功(gong)檢測方式(shi)，以功(gong)率(lv)因數(shu)(shu)、網側(ce)電(dian)(dian)壓(ya)(ya)作(zuo)(zuo)為(wei)控制目標(biao)(biao)，動態跟蹤電(dian)(dian)網電(dian)(dian)能(neng)(neng)相關指(zhi)標(biao)(biao)的(de)(de)變(bian)化，并根(gen)據變(bian)化情況調節(jie)無(wu)功(gong)輸出(chu)，實(shi)(shi)現(xian)電(dian)(dian)網的(de)(de)高(gao)(gao)(gao)電(dian)(dian)能(neng)(neng)質(zhi)量運(yun)行。控制器采用(yong)(yong)高(gao)(gao)(gao)速DSP和FPGA，實(shi)(shi)現(xian)全數(shu)(shu)字(zi)化控制，電(dian)(dian)壓(ya)(ya)電(dian)(dian)流(liu)數(shu)(shu)字(zi)閉環和載波(bo)移(yi)相技(ji)術，信號采用(yong)(yong)光纖傳輸，實(shi)(shi)現(xian)了高(gao)(gao)(gao)壓(ya)(ya)隔(ge)離，提高(gao)(gao)(gao)了整機的(de)(de)穩定(ding)性和可(ke)靠性。采用(yong)(yong)IGBT組(zu)成的(de)(de)H橋功(gong)率(lv)模(mo)塊(kuai)鏈作(zuo)(zuo)為(wei)逆變(bian)主電(dian)(dian)路的(de)(de)結構(gou)形式(shi)，拓撲(pu)簡單，性能(neng)(neng)可(ke)靠，并輔助(zhu)以小(xiao)容量儲能(neng)(neng)元(yuan)件，整機輸出(chu)電(dian)(dian)壓(ya)(ya)由(you)(you)多(duo)個電(dian)(dian)平臺階合(he)成階梯(ti)波(bo)，經過輸出(chu)電(dian)(dian)抗濾(lv)波(bo)后正弦(xian)度好(hao)。RSVG由(you)(you)于(yu)輸出(chu)電(dian)(dian)壓(ya)(ya)電(dian)(dian)平數(shu)(shu)多(duo)，輸出(chu)波(bo)形具有更(geng)好(hao)的(de)(de)諧波(bo)頻譜，因此RSVG可(ke)稱(cheng)為(wei)“完美無(wu)諧波(bo)變(bian)流(liu)器”。
