RSVG高壓靜止無功發生器——35kV直掛SVG（水冷戶外）

榮信興業(ye)高(gao)(gao)壓無(wu)功(gong)補償裝(zhuang)置（簡稱RSVG），采用(yong)瞬時無(wu)功(gong)功(gong)率理論的(de)無(wu)功(gong)檢測(ce)方式(shi)，以功(gong)率因數、網側電(dian)(dian)(dian)(dian)壓作(zuo)為(wei)控(kong)制目標，動態(tai)跟蹤電(dian)(dian)(dian)(dian)網電(dian)(dian)(dian)(dian)能(neng)(neng)相關指標的(de)變(bian)(bian)化，并根據變(bian)(bian)化情(qing)況調節(jie)無(wu)功(gong)輸(shu)(shu)(shu)出(chu)(chu)，實現電(dian)(dian)(dian)(dian)網的(de)高(gao)(gao)電(dian)(dian)(dian)(dian)能(neng)(neng)質量運(yun)行(xing)。控(kong)制器(qi)采用(yong)高(gao)(gao)速DSP和FPGA，實現全數字(zi)化控(kong)制，電(dian)(dian)(dian)(dian)壓電(dian)(dian)(dian)(dian)流(liu)數字(zi)閉環和載(zai)波(bo)(bo)(bo)移相技術(shu)，信號采用(yong)光纖傳輸(shu)(shu)(shu)，實現了(le)高(gao)(gao)壓隔離(li)，提(ti)高(gao)(gao)了(le)整機(ji)的(de)穩(wen)定性和可(ke)靠性。采用(yong)IGBT組成(cheng)(cheng)的(de)H橋(qiao)功(gong)率模塊鏈作(zuo)為(wei)逆變(bian)(bian)主電(dian)(dian)(dian)(dian)路的(de)結構形(xing)式(shi)，拓撲簡單(dan)，性能(neng)(neng)可(ke)靠，并輔(fu)助以小容量儲能(neng)(neng)元件，整機(ji)輸(shu)(shu)(shu)出(chu)(chu)電(dian)(dian)(dian)(dian)壓由(you)多個電(dian)(dian)(dian)(dian)平臺(tai)階(jie)合成(cheng)(cheng)階(jie)梯波(bo)(bo)(bo)，經(jing)過(guo)輸(shu)(shu)(shu)出(chu)(chu)電(dian)(dian)(dian)(dian)抗(kang)濾(lv)波(bo)(bo)(bo)后正弦度好。RSVG由(you)于輸(shu)(shu)(shu)出(chu)(chu)電(dian)(dian)(dian)(dian)壓電(dian)(dian)(dian)(dian)平數多，輸(shu)(shu)(shu)出(chu)(chu)波(bo)(bo)(bo)形(xing)具有更好的(de)諧波(bo)(bo)(bo)頻譜，因此(ci)RSVG可(ke)稱為(wei)“完美無(wu)諧波(bo)(bo)(bo)變(bian)(bian)流(liu)器(qi)”。
