RSVG高壓靜止無功發生器——35kV直掛SVG（水冷戶外）

榮信(xin)(xin)興業高壓無(wu)功(gong)(gong)(gong)補償裝置（簡稱(cheng)RSVG），采(cai)用瞬時無(wu)功(gong)(gong)(gong)功(gong)(gong)(gong)率(lv)理(li)論的(de)(de)(de)無(wu)功(gong)(gong)(gong)檢測方式(shi)，以功(gong)(gong)(gong)率(lv)因(yin)數、網(wang)(wang)側電(dian)(dian)(dian)(dian)壓作為(wei)(wei)控制目(mu)標(biao)，動態跟蹤電(dian)(dian)(dian)(dian)網(wang)(wang)電(dian)(dian)(dian)(dian)能相(xiang)關指標(biao)的(de)(de)(de)變化(hua)(hua)，并根據變化(hua)(hua)情況調節無(wu)功(gong)(gong)(gong)輸出(chu)(chu)，實(shi)現(xian)電(dian)(dian)(dian)(dian)網(wang)(wang)的(de)(de)(de)高電(dian)(dian)(dian)(dian)能質量(liang)運(yun)行。控制器采(cai)用高速DSP和FPGA，實(shi)現(xian)全數字化(hua)(hua)控制，電(dian)(dian)(dian)(dian)壓電(dian)(dian)(dian)(dian)流數字閉(bi)環(huan)和載(zai)波(bo)(bo)(bo)移相(xiang)技術，信(xin)(xin)號(hao)采(cai)用光纖傳輸，實(shi)現(xian)了高壓隔(ge)離(li)，提高了整機(ji)的(de)(de)(de)穩定性(xing)和可(ke)靠性(xing)。采(cai)用IGBT組成的(de)(de)(de)H橋(qiao)功(gong)(gong)(gong)率(lv)模塊鏈作為(wei)(wei)逆變主電(dian)(dian)(dian)(dian)路的(de)(de)(de)結構形式(shi)，拓(tuo)撲(pu)簡單(dan)，性(xing)能可(ke)靠，并輔(fu)助以小(xiao)容量(liang)儲能元(yuan)件，整機(ji)輸出(chu)(chu)電(dian)(dian)(dian)(dian)壓由多(duo)個電(dian)(dian)(dian)(dian)平臺階合(he)成階梯波(bo)(bo)(bo)，經過輸出(chu)(chu)電(dian)(dian)(dian)(dian)抗濾波(bo)(bo)(bo)后正弦(xian)度好(hao)。RSVG由于(yu)輸出(chu)(chu)電(dian)(dian)(dian)(dian)壓電(dian)(dian)(dian)(dian)平數多(duo)，輸出(chu)(chu)波(bo)(bo)(bo)形具有更好(hao)的(de)(de)(de)諧波(bo)(bo)(bo)頻譜(pu)，因(yin)此RSVG可(ke)稱(cheng)為(wei)(wei)“完(wan)美無(wu)諧波(bo)(bo)(bo)變流器”。
