RSVG高壓靜止無功發生器——35kV直掛SVG（水冷戶外）

榮信(xin)興業(ye)高壓(ya)無(wu)功(gong)補(bu)償裝置（簡稱(cheng)RSVG），采(cai)用瞬時無(wu)功(gong)功(gong)率理(li)論的(de)(de)無(wu)功(gong)檢測方(fang)式，以功(gong)率因(yin)數(shu)、網側(ce)電(dian)(dian)(dian)(dian)壓(ya)作為控制(zhi)(zhi)目(mu)標，動態跟蹤電(dian)(dian)(dian)(dian)網電(dian)(dian)(dian)(dian)能(neng)相(xiang)關(guan)指(zhi)標的(de)(de)變(bian)化(hua)，并(bing)根據變(bian)化(hua)情況(kuang)調節無(wu)功(gong)輸出(chu)(chu)，實(shi)現(xian)電(dian)(dian)(dian)(dian)網的(de)(de)高電(dian)(dian)(dian)(dian)能(neng)質量運行。控制(zhi)(zhi)器采(cai)用高速(su)DSP和FPGA，實(shi)現(xian)全數(shu)字化(hua)控制(zhi)(zhi)，電(dian)(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)(dian)流數(shu)字閉環和載波(bo)(bo)移相(xiang)技術，信(xin)號(hao)采(cai)用光纖傳輸，實(shi)現(xian)了高壓(ya)隔離，提(ti)高了整(zheng)機的(de)(de)穩定性(xing)和可靠性(xing)。采(cai)用IGBT組成(cheng)(cheng)的(de)(de)H橋(qiao)功(gong)率模(mo)塊鏈作為逆變(bian)主電(dian)(dian)(dian)(dian)路的(de)(de)結構形式，拓撲簡單，性(xing)能(neng)可靠，并(bing)輔助(zhu)以小容量儲能(neng)元件，整(zheng)機輸出(chu)(chu)電(dian)(dian)(dian)(dian)壓(ya)由多個電(dian)(dian)(dian)(dian)平(ping)臺階合成(cheng)(cheng)階梯波(bo)(bo)，經過輸出(chu)(chu)電(dian)(dian)(dian)(dian)抗濾波(bo)(bo)后正弦(xian)度(du)好。RSVG由于輸出(chu)(chu)電(dian)(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)(dian)平(ping)數(shu)多，輸出(chu)(chu)波(bo)(bo)形具(ju)有(you)更好的(de)(de)諧波(bo)(bo)頻譜，因(yin)此RSVG可稱(cheng)為“完(wan)美無(wu)諧波(bo)(bo)變(bian)流器”。
