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)壓(ya)(ya)無(wu)功(gong)(gong)補償裝置（簡稱RSVG），采(cai)用(yong)(yong)瞬(shun)時無(wu)功(gong)(gong)功(gong)(gong)率理論的(de)(de)(de)(de)無(wu)功(gong)(gong)檢測方(fang)式(shi)(shi)，以功(gong)(gong)率因數、網(wang)側電壓(ya)(ya)作(zuo)為(wei)控(kong)制(zhi)(zhi)目標，動(dong)態跟蹤電網(wang)電能(neng)(neng)相關指標的(de)(de)(de)(de)變(bian)化(hua)，并(bing)根據變(bian)化(hua)情況調節無(wu)功(gong)(gong)輸(shu)出(chu)(chu)，實現(xian)(xian)電網(wang)的(de)(de)(de)(de)高(gao)(gao)電能(neng)(neng)質(zhi)量(liang)運行。控(kong)制(zhi)(zhi)器采(cai)用(yong)(yong)高(gao)(gao)速DSP和FPGA，實現(xian)(xian)全數字化(hua)控(kong)制(zhi)(zhi)，電壓(ya)(ya)電流(liu)數字閉環和載(zai)波移相技術，信號采(cai)用(yong)(yong)光纖傳輸(shu)，實現(xian)(xian)了高(gao)(gao)壓(ya)(ya)隔離，提高(gao)(gao)了整(zheng)(zheng)機的(de)(de)(de)(de)穩定性和可靠(kao)性。采(cai)用(yong)(yong)IGBT組(zu)成的(de)(de)(de)(de)H橋功(gong)(gong)率模塊鏈作(zuo)為(wei)逆變(bian)主電路的(de)(de)(de)(de)結構形式(shi)(shi)，拓撲簡單，性能(neng)(neng)可靠(kao)，并(bing)輔(fu)助以小容量(liang)儲能(neng)(neng)元件，整(zheng)(zheng)機輸(shu)出(chu)(chu)電壓(ya)(ya)由多(duo)個(ge)電平臺(tai)階合(he)成階梯波，經過輸(shu)出(chu)(chu)電抗濾波后正弦度好(hao)。RSVG由于輸(shu)出(chu)(chu)電壓(ya)(ya)電平數多(duo)，輸(shu)出(chu)(chu)波形具有更好(hao)的(de)(de)(de)(de)諧波頻譜，因此RSVG可稱為(wei)“完美無(wu)諧波變(bian)流(liu)器”。
