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)壓(ya)無(wu)功(gong)(gong)(gong)補(bu)償裝置（簡稱(cheng)RSVG），采(cai)用(yong)(yong)瞬時(shi)無(wu)功(gong)(gong)(gong)功(gong)(gong)(gong)率理論(lun)的(de)無(wu)功(gong)(gong)(gong)檢測方式，以(yi)功(gong)(gong)(gong)率因數(shu)、網側電(dian)(dian)(dian)(dian)壓(ya)作(zuo)為控(kong)制目標(biao)，動態跟蹤(zong)電(dian)(dian)(dian)(dian)網電(dian)(dian)(dian)(dian)能(neng)相關指標(biao)的(de)變化(hua)，并(bing)根據變化(hua)情況(kuang)調(diao)節無(wu)功(gong)(gong)(gong)輸(shu)(shu)出(chu)，實現電(dian)(dian)(dian)(dian)網的(de)高(gao)電(dian)(dian)(dian)(dian)能(neng)質量運行。控(kong)制器采(cai)用(yong)(yong)高(gao)速DSP和FPGA，實現全數(shu)字化(hua)控(kong)制，電(dian)(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)(dian)流數(shu)字閉環和載(zai)波(bo)(bo)移相技(ji)術(shu)，信號采(cai)用(yong)(yong)光纖傳輸(shu)(shu)，實現了(le)高(gao)壓(ya)隔(ge)離，提高(gao)了(le)整(zheng)機的(de)穩定性(xing)和可靠性(xing)。采(cai)用(yong)(yong)IGBT組成(cheng)的(de)H橋功(gong)(gong)(gong)率模塊(kuai)鏈作(zuo)為逆變主電(dian)(dian)(dian)(dian)路的(de)結構形(xing)式，拓撲(pu)簡單，性(xing)能(neng)可靠，并(bing)輔(fu)助以(yi)小容量儲能(neng)元件，整(zheng)機輸(shu)(shu)出(chu)電(dian)(dian)(dian)(dian)壓(ya)由多個電(dian)(dian)(dian)(dian)平臺階合成(cheng)階梯(ti)波(bo)(bo)，經過輸(shu)(shu)出(chu)電(dian)(dian)(dian)(dian)抗濾波(bo)(bo)后正弦度好。RSVG由于輸(shu)(shu)出(chu)電(dian)(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)(dian)平數(shu)多，輸(shu)(shu)出(chu)波(bo)(bo)形(xing)具有更好的(de)諧(xie)(xie)波(bo)(bo)頻譜，因此RSVG可稱(cheng)為“完美無(wu)諧(xie)(xie)波(bo)(bo)變流器”。
