RSVG高壓靜止無功發生器——35kV直掛SVG（水冷戶外）

榮信(xin)興業高(gao)壓(ya)(ya)(ya)無功(gong)補償(chang)裝置（簡稱(cheng)RSVG），采用(yong)瞬時無功(gong)功(gong)率(lv)理論的(de)(de)無功(gong)檢測方式(shi)，以功(gong)率(lv)因數(shu)(shu)、網側電(dian)(dian)壓(ya)(ya)(ya)作(zuo)為(wei)控(kong)制目標，動態跟蹤(zong)電(dian)(dian)網電(dian)(dian)能相關指(zhi)標的(de)(de)變化，并根據變化情況調節無功(gong)輸(shu)(shu)出(chu)，實(shi)現電(dian)(dian)網的(de)(de)高(gao)電(dian)(dian)能質量運行(xing)。控(kong)制器(qi)采用(yong)高(gao)速DSP和(he)FPGA，實(shi)現全(quan)數(shu)(shu)字(zi)化控(kong)制，電(dian)(dian)壓(ya)(ya)(ya)電(dian)(dian)流(liu)數(shu)(shu)字(zi)閉環和(he)載波(bo)移相技術，信(xin)號(hao)采用(yong)光纖傳輸(shu)(shu)，實(shi)現了(le)高(gao)壓(ya)(ya)(ya)隔離，提高(gao)了(le)整(zheng)機的(de)(de)穩定性(xing)和(he)可(ke)靠性(xing)。采用(yong)IGBT組成的(de)(de)H橋功(gong)率(lv)模塊鏈(lian)作(zuo)為(wei)逆變主電(dian)(dian)路的(de)(de)結構形式(shi)，拓撲簡單，性(xing)能可(ke)靠，并輔助以小(xiao)容量儲能元件，整(zheng)機輸(shu)(shu)出(chu)電(dian)(dian)壓(ya)(ya)(ya)由(you)多個電(dian)(dian)平臺(tai)階(jie)合成階(jie)梯波(bo)，經過輸(shu)(shu)出(chu)電(dian)(dian)抗濾波(bo)后正弦度(du)好(hao)。RSVG由(you)于輸(shu)(shu)出(chu)電(dian)(dian)壓(ya)(ya)(ya)電(dian)(dian)平數(shu)(shu)多，輸(shu)(shu)出(chu)波(bo)形具有更(geng)好(hao)的(de)(de)諧(xie)波(bo)頻譜，因此RSVG可(ke)稱(cheng)為(wei)“完美(mei)無諧(xie)波(bo)變流(liu)器(qi)”。
