RSVG高壓靜止無功發生器——35kV直掛SVG（水冷戶外）

榮(rong)信興業高(gao)(gao)壓(ya)(ya)無(wu)功補償裝置（簡(jian)稱RSVG），采(cai)(cai)(cai)用(yong)(yong)瞬時無(wu)功功率理論的(de)無(wu)功檢測方式(shi)，以功率因數、網(wang)側(ce)電(dian)(dian)(dian)壓(ya)(ya)作為(wei)控制目標，動態跟蹤電(dian)(dian)(dian)網(wang)電(dian)(dian)(dian)能相(xiang)關(guan)指(zhi)標的(de)變(bian)化(hua)，并(bing)根據變(bian)化(hua)情況調節(jie)無(wu)功輸(shu)出(chu)(chu)，實現電(dian)(dian)(dian)網(wang)的(de)高(gao)(gao)電(dian)(dian)(dian)能質量(liang)運行(xing)。控制器采(cai)(cai)(cai)用(yong)(yong)高(gao)(gao)速DSP和FPGA，實現全數字化(hua)控制，電(dian)(dian)(dian)壓(ya)(ya)電(dian)(dian)(dian)流數字閉環和載波移相(xiang)技(ji)術，信號(hao)采(cai)(cai)(cai)用(yong)(yong)光纖傳輸(shu)，實現了高(gao)(gao)壓(ya)(ya)隔(ge)離，提高(gao)(gao)了整(zheng)機的(de)穩定性和可(ke)靠性。采(cai)(cai)(cai)用(yong)(yong)IGBT組成的(de)H橋功率模塊鏈(lian)作為(wei)逆變(bian)主電(dian)(dian)(dian)路的(de)結構形(xing)式(shi)，拓撲簡(jian)單，性能可(ke)靠，并(bing)輔助以小容量(liang)儲(chu)能元(yuan)件，整(zheng)機輸(shu)出(chu)(chu)電(dian)(dian)(dian)壓(ya)(ya)由多(duo)(duo)個電(dian)(dian)(dian)平臺(tai)階(jie)合成階(jie)梯波，經(jing)過輸(shu)出(chu)(chu)電(dian)(dian)(dian)抗濾(lv)波后(hou)正弦(xian)度(du)好(hao)。RSVG由于輸(shu)出(chu)(chu)電(dian)(dian)(dian)壓(ya)(ya)電(dian)(dian)(dian)平數多(duo)(duo)，輸(shu)出(chu)(chu)波形(xing)具有更好(hao)的(de)諧波頻(pin)譜(pu)，因此RSVG可(ke)稱為(wei)“完美無(wu)諧波變(bian)流器”。
