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)功(gong)(gong)(gong)補償裝置（簡稱(cheng)RSVG），采用(yong)瞬時無(wu)功(gong)(gong)(gong)功(gong)(gong)(gong)率(lv)理(li)論的無(wu)功(gong)(gong)(gong)檢測方式，以功(gong)(gong)(gong)率(lv)因數(shu)、網(wang)側電(dian)(dian)(dian)壓(ya)(ya)作為控(kong)制(zhi)目標，動態(tai)跟蹤電(dian)(dian)(dian)網(wang)電(dian)(dian)(dian)能相(xiang)關指標的變化(hua)(hua)，并(bing)根(gen)據變化(hua)(hua)情況(kuang)調節無(wu)功(gong)(gong)(gong)輸出(chu)(chu)，實現電(dian)(dian)(dian)網(wang)的高電(dian)(dian)(dian)能質量運(yun)行。控(kong)制(zhi)器采用(yong)高速(su)DSP和(he)(he)FPGA，實現全數(shu)字化(hua)(hua)控(kong)制(zhi)，電(dian)(dian)(dian)壓(ya)(ya)電(dian)(dian)(dian)流(liu)數(shu)字閉環和(he)(he)載波(bo)移相(xiang)技(ji)術，信號采用(yong)光纖(xian)傳(chuan)輸，實現了(le)高壓(ya)(ya)隔離，提高了(le)整機(ji)(ji)的穩定性和(he)(he)可(ke)靠性。采用(yong)IGBT組(zu)成(cheng)的H橋功(gong)(gong)(gong)率(lv)模塊(kuai)鏈作為逆變主電(dian)(dian)(dian)路(lu)的結構形(xing)式，拓(tuo)撲(pu)簡單，性能可(ke)靠，并(bing)輔(fu)助以小(xiao)容(rong)量儲能元件，整機(ji)(ji)輸出(chu)(chu)電(dian)(dian)(dian)壓(ya)(ya)由多個(ge)電(dian)(dian)(dian)平臺階(jie)合成(cheng)階(jie)梯(ti)波(bo)，經過輸出(chu)(chu)電(dian)(dian)(dian)抗濾波(bo)后正弦度好。RSVG由于輸出(chu)(chu)電(dian)(dian)(dian)壓(ya)(ya)電(dian)(dian)(dian)平數(shu)多，輸出(chu)(chu)波(bo)形(xing)具有更好的諧波(bo)頻(pin)譜，因此(ci)RSVG可(ke)稱(cheng)為“完美無(wu)諧波(bo)變流(liu)器”。
