RSVG高壓靜止無功發生器——35kV直掛SVG（水冷戶外）

榮信興業高壓(ya)(ya)無(wu)(wu)功(gong)補償裝置（簡(jian)稱(cheng)RSVG），采用(yong)瞬(shun)時無(wu)(wu)功(gong)功(gong)率理論的(de)(de)(de)無(wu)(wu)功(gong)檢測(ce)方式，以(yi)功(gong)率因數、網(wang)側電(dian)(dian)(dian)(dian)壓(ya)(ya)作(zuo)為控制目標，動態跟蹤(zong)電(dian)(dian)(dian)(dian)網(wang)電(dian)(dian)(dian)(dian)能(neng)(neng)相關(guan)指標的(de)(de)(de)變化，并(bing)根據變化情況調節無(wu)(wu)功(gong)輸(shu)出(chu)，實現(xian)電(dian)(dian)(dian)(dian)網(wang)的(de)(de)(de)高電(dian)(dian)(dian)(dian)能(neng)(neng)質量運(yun)行。控制器采用(yong)高速DSP和(he)FPGA，實現(xian)全數字(zi)化控制，電(dian)(dian)(dian)(dian)壓(ya)(ya)電(dian)(dian)(dian)(dian)流(liu)數字(zi)閉環和(he)載波(bo)(bo)(bo)移相技術，信號采用(yong)光纖傳輸(shu)，實現(xian)了(le)(le)高壓(ya)(ya)隔(ge)離，提高了(le)(le)整機(ji)的(de)(de)(de)穩(wen)定性(xing)和(he)可靠(kao)性(xing)。采用(yong)IGBT組成的(de)(de)(de)H橋功(gong)率模塊鏈作(zuo)為逆變主電(dian)(dian)(dian)(dian)路的(de)(de)(de)結構形式，拓撲簡(jian)單，性(xing)能(neng)(neng)可靠(kao)，并(bing)輔(fu)助以(yi)小(xiao)容量儲能(neng)(neng)元件，整機(ji)輸(shu)出(chu)電(dian)(dian)(dian)(dian)壓(ya)(ya)由多個電(dian)(dian)(dian)(dian)平臺階合成階梯波(bo)(bo)(bo)，經過輸(shu)出(chu)電(dian)(dian)(dian)(dian)抗濾波(bo)(bo)(bo)后正弦度好。RSVG由于(yu)輸(shu)出(chu)電(dian)(dian)(dian)(dian)壓(ya)(ya)電(dian)(dian)(dian)(dian)平數多，輸(shu)出(chu)波(bo)(bo)(bo)形具有更好的(de)(de)(de)諧波(bo)(bo)(bo)頻譜，因此RSVG可稱(cheng)為“完美無(wu)(wu)諧波(bo)(bo)(bo)變流(liu)器”。
