RSVG高壓靜止無功發生器——35kV直掛SVG（水冷戶外）

榮信興業高(gao)壓(ya)(ya)無功補(bu)償(chang)裝置(zhi)（簡稱RSVG），采(cai)用(yong)瞬時無功功率(lv)理論(lun)的(de)無功檢測(ce)方(fang)式，以功率(lv)因數、網(wang)側(ce)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)作為控(kong)制(zhi)目標，動態跟蹤電(dian)(dian)(dian)(dian)(dian)網(wang)電(dian)(dian)(dian)(dian)(dian)能相(xiang)關指標的(de)變(bian)化，并(bing)根據變(bian)化情況調節無功輸(shu)出，實現電(dian)(dian)(dian)(dian)(dian)網(wang)的(de)高(gao)電(dian)(dian)(dian)(dian)(dian)能質量運行(xing)。控(kong)制(zhi)器采(cai)用(yong)高(gao)速DSP和(he)FPGA，實現全數字化控(kong)制(zhi)，電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)電(dian)(dian)(dian)(dian)(dian)流(liu)數字閉(bi)環和(he)載波(bo)移相(xiang)技術，信號采(cai)用(yong)光纖傳輸(shu)，實現了(le)高(gao)壓(ya)(ya)隔離，提高(gao)了(le)整(zheng)機(ji)的(de)穩定性和(he)可(ke)靠性。采(cai)用(yong)IGBT組成(cheng)的(de)H橋功率(lv)模塊鏈作為逆變(bian)主電(dian)(dian)(dian)(dian)(dian)路的(de)結構形(xing)式，拓撲簡單(dan)，性能可(ke)靠，并(bing)輔助以小容量儲能元件，整(zheng)機(ji)輸(shu)出電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)由多(duo)個電(dian)(dian)(dian)(dian)(dian)平(ping)臺(tai)階(jie)合成(cheng)階(jie)梯波(bo)，經過輸(shu)出電(dian)(dian)(dian)(dian)(dian)抗濾(lv)波(bo)后正(zheng)弦度好。RSVG由于輸(shu)出電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)電(dian)(dian)(dian)(dian)(dian)平(ping)數多(duo)，輸(shu)出波(bo)形(xing)具有更好的(de)諧(xie)(xie)波(bo)頻譜，因此RSVG可(ke)稱為“完美無諧(xie)(xie)波(bo)變(bian)流(liu)器”。
