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(ya)無(wu)功(gong)補償裝置（簡稱RSVG），采用(yong)瞬時無(wu)功(gong)功(gong)率理論的無(wu)功(gong)檢測方式，以功(gong)率因數(shu)、網側電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)作為控(kong)制(zhi)目標(biao)，動態跟蹤電(dian)(dian)(dian)(dian)(dian)(dian)網電(dian)(dian)(dian)(dian)(dian)(dian)能(neng)(neng)相(xiang)關指標(biao)的變(bian)化，并(bing)根據(ju)變(bian)化情況(kuang)調節無(wu)功(gong)輸出(chu)，實現電(dian)(dian)(dian)(dian)(dian)(dian)網的高(gao)(gao)電(dian)(dian)(dian)(dian)(dian)(dian)能(neng)(neng)質量(liang)運行。控(kong)制(zhi)器采用(yong)高(gao)(gao)速(su)DSP和FPGA，實現全(quan)數(shu)字(zi)化控(kong)制(zhi)，電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)流數(shu)字(zi)閉環和載(zai)波(bo)移相(xiang)技術，信號采用(yong)光(guang)纖傳輸，實現了高(gao)(gao)壓(ya)隔離，提高(gao)(gao)了整機(ji)的穩定性(xing)和可靠性(xing)。采用(yong)IGBT組成的H橋功(gong)率模塊(kuai)鏈作為逆變(bian)主電(dian)(dian)(dian)(dian)(dian)(dian)路的結構形式，拓(tuo)撲簡單，性(xing)能(neng)(neng)可靠，并(bing)輔助以小容(rong)量(liang)儲能(neng)(neng)元件，整機(ji)輸出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)由多個(ge)電(dian)(dian)(dian)(dian)(dian)(dian)平(ping)臺階合成階梯波(bo)，經過輸出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)抗濾波(bo)后正弦度好(hao)。RSVG由于輸出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)平(ping)數(shu)多，輸出(chu)波(bo)形具有更(geng)好(hao)的諧波(bo)頻(pin)譜，因此RSVG可稱為“完(wan)美(mei)無(wu)諧波(bo)變(bian)流器”。
