RSVG高壓靜止無功發生器——35kV直掛SVG（水冷戶外）

榮信興業高壓(ya)(ya)無(wu)(wu)(wu)功(gong)(gong)補償裝置(zhi)（簡稱RSVG），采用瞬(shun)時無(wu)(wu)(wu)功(gong)(gong)功(gong)(gong)率理(li)論(lun)的(de)(de)(de)無(wu)(wu)(wu)功(gong)(gong)檢測(ce)方(fang)式，以(yi)功(gong)(gong)率因數(shu)、網側電(dian)(dian)壓(ya)(ya)作為控制(zhi)目標(biao)，動態跟(gen)蹤電(dian)(dian)網電(dian)(dian)能(neng)相關指標(biao)的(de)(de)(de)變化(hua)，并根據變化(hua)情(qing)況調節無(wu)(wu)(wu)功(gong)(gong)輸(shu)(shu)(shu)出(chu)，實現電(dian)(dian)網的(de)(de)(de)高電(dian)(dian)能(neng)質(zhi)量運行。控制(zhi)器采用高速DSP和FPGA，實現全數(shu)字(zi)化(hua)控制(zhi)，電(dian)(dian)壓(ya)(ya)電(dian)(dian)流數(shu)字(zi)閉環和載波移相技術，信號采用光纖傳輸(shu)(shu)(shu)，實現了高壓(ya)(ya)隔離，提高了整機(ji)的(de)(de)(de)穩定性和可(ke)靠性。采用IGBT組成的(de)(de)(de)H橋功(gong)(gong)率模塊(kuai)鏈作為逆變主電(dian)(dian)路的(de)(de)(de)結(jie)構(gou)形式，拓(tuo)撲簡單，性能(neng)可(ke)靠，并輔助以(yi)小(xiao)容量儲能(neng)元件，整機(ji)輸(shu)(shu)(shu)出(chu)電(dian)(dian)壓(ya)(ya)由(you)多(duo)個(ge)電(dian)(dian)平臺階合成階梯波，經過輸(shu)(shu)(shu)出(chu)電(dian)(dian)抗(kang)濾波后正弦度好。RSVG由(you)于輸(shu)(shu)(shu)出(chu)電(dian)(dian)壓(ya)(ya)電(dian)(dian)平數(shu)多(duo)，輸(shu)(shu)(shu)出(chu)波形具有更好的(de)(de)(de)諧波頻譜，因此RSVG可(ke)稱為“完美(mei)無(wu)(wu)(wu)諧波變流器”。
