RSVG高壓靜止無功發生器——35kV直掛SVG（水冷戶外）

榮信興(xing)業高壓(ya)無(wu)功(gong)補償裝置（簡稱RSVG），采(cai)用(yong)瞬(shun)時無(wu)功(gong)功(gong)率理(li)論(lun)的(de)無(wu)功(gong)檢測(ce)方(fang)式，以(yi)功(gong)率因(yin)數(shu)、網側電(dian)(dian)壓(ya)作為(wei)(wei)控制(zhi)目標，動態跟蹤電(dian)(dian)網電(dian)(dian)能(neng)相關指標的(de)變(bian)化(hua)，并根據(ju)變(bian)化(hua)情況調節無(wu)功(gong)輸(shu)(shu)(shu)出(chu)，實(shi)現(xian)(xian)電(dian)(dian)網的(de)高電(dian)(dian)能(neng)質(zhi)量運行(xing)。控制(zhi)器(qi)(qi)采(cai)用(yong)高速DSP和FPGA，實(shi)現(xian)(xian)全數(shu)字(zi)化(hua)控制(zhi)，電(dian)(dian)壓(ya)電(dian)(dian)流數(shu)字(zi)閉(bi)環(huan)和載波(bo)(bo)移相技術，信號采(cai)用(yong)光纖傳輸(shu)(shu)(shu)，實(shi)現(xian)(xian)了(le)高壓(ya)隔離，提高了(le)整(zheng)機(ji)的(de)穩(wen)定性和可靠性。采(cai)用(yong)IGBT組成的(de)H橋功(gong)率模塊鏈作為(wei)(wei)逆變(bian)主電(dian)(dian)路的(de)結構形(xing)式，拓撲簡單，性能(neng)可靠，并輔助以(yi)小容量儲能(neng)元件(jian)，整(zheng)機(ji)輸(shu)(shu)(shu)出(chu)電(dian)(dian)壓(ya)由多個電(dian)(dian)平臺階合成階梯波(bo)(bo)，經過輸(shu)(shu)(shu)出(chu)電(dian)(dian)抗濾波(bo)(bo)后正(zheng)弦度好(hao)。RSVG由于輸(shu)(shu)(shu)出(chu)電(dian)(dian)壓(ya)電(dian)(dian)平數(shu)多，輸(shu)(shu)(shu)出(chu)波(bo)(bo)形(xing)具有(you)更好(hao)的(de)諧波(bo)(bo)頻譜，因(yin)此RSVG可稱為(wei)(wei)“完美(mei)無(wu)諧波(bo)(bo)變(bian)流器(qi)(qi)”。
