RSVG高壓靜止無功發生器——35kV直掛SVG（水冷戶外）

榮信興業高(gao)壓(ya)無功(gong)(gong)補(bu)償裝置(zhi)（簡稱RSVG），采用瞬時無功(gong)(gong)功(gong)(gong)率(lv)理論的(de)(de)(de)無功(gong)(gong)檢測方(fang)式(shi)，以功(gong)(gong)率(lv)因數(shu)、網側電(dian)(dian)(dian)壓(ya)作(zuo)為控制目標，動(dong)態跟蹤電(dian)(dian)(dian)網電(dian)(dian)(dian)能相關指(zhi)標的(de)(de)(de)變化(hua)，并根(gen)據變化(hua)情(qing)況調(diao)節無功(gong)(gong)輸出(chu)，實(shi)現(xian)(xian)電(dian)(dian)(dian)網的(de)(de)(de)高(gao)電(dian)(dian)(dian)能質量(liang)運行。控制器采用高(gao)速DSP和(he)FPGA，實(shi)現(xian)(xian)全數(shu)字(zi)(zi)化(hua)控制，電(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)流數(shu)字(zi)(zi)閉環和(he)載波(bo)(bo)(bo)移相技術，信號采用光纖傳輸，實(shi)現(xian)(xian)了高(gao)壓(ya)隔離，提高(gao)了整機(ji)的(de)(de)(de)穩定性(xing)和(he)可(ke)靠性(xing)。采用IGBT組成的(de)(de)(de)H橋功(gong)(gong)率(lv)模塊鏈作(zuo)為逆變主電(dian)(dian)(dian)路的(de)(de)(de)結構形式(shi)，拓撲簡單，性(xing)能可(ke)靠，并輔助以小容量(liang)儲(chu)能元(yuan)件，整機(ji)輸出(chu)電(dian)(dian)(dian)壓(ya)由多個電(dian)(dian)(dian)平臺階合成階梯波(bo)(bo)(bo)，經過(guo)輸出(chu)電(dian)(dian)(dian)抗濾波(bo)(bo)(bo)后正(zheng)弦度(du)好。RSVG由于輸出(chu)電(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)平數(shu)多，輸出(chu)波(bo)(bo)(bo)形具有更(geng)好的(de)(de)(de)諧(xie)波(bo)(bo)(bo)頻譜(pu)，因此RSVG可(ke)稱為“完(wan)美無諧(xie)波(bo)(bo)(bo)變流器”。
