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)無功補(bu)償裝置（簡(jian)稱(cheng)RSVG），采用(yong)瞬(shun)時無功功率(lv)(lv)理論的(de)無功檢測方式(shi)，以(yi)功率(lv)(lv)因數(shu)、網(wang)側電(dian)(dian)(dian)(dian)壓(ya)作為(wei)控制目標，動態跟蹤電(dian)(dian)(dian)(dian)網(wang)電(dian)(dian)(dian)(dian)能(neng)相關(guan)指標的(de)變(bian)(bian)化(hua)(hua)，并根據變(bian)(bian)化(hua)(hua)情況調節無功輸(shu)出(chu)，實現(xian)(xian)電(dian)(dian)(dian)(dian)網(wang)的(de)高(gao)電(dian)(dian)(dian)(dian)能(neng)質(zhi)量(liang)(liang)運行。控制器(qi)采用(yong)高(gao)速DSP和(he)FPGA，實現(xian)(xian)全數(shu)字化(hua)(hua)控制，電(dian)(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)(dian)流數(shu)字閉環和(he)載(zai)波(bo)(bo)移相技(ji)術，信號采用(yong)光纖傳(chuan)輸(shu)，實現(xian)(xian)了高(gao)壓(ya)隔離，提高(gao)了整(zheng)機(ji)(ji)的(de)穩定性和(he)可靠性。采用(yong)IGBT組成(cheng)的(de)H橋功率(lv)(lv)模塊鏈作為(wei)逆變(bian)(bian)主電(dian)(dian)(dian)(dian)路的(de)結(jie)構形(xing)式(shi)，拓(tuo)撲簡(jian)單(dan)，性能(neng)可靠，并輔助以(yi)小容量(liang)(liang)儲能(neng)元件(jian)，整(zheng)機(ji)(ji)輸(shu)出(chu)電(dian)(dian)(dian)(dian)壓(ya)由(you)多個電(dian)(dian)(dian)(dian)平臺階合成(cheng)階梯波(bo)(bo)，經過輸(shu)出(chu)電(dian)(dian)(dian)(dian)抗(kang)濾波(bo)(bo)后正弦度好。RSVG由(you)于輸(shu)出(chu)電(dian)(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)(dian)平數(shu)多，輸(shu)出(chu)波(bo)(bo)形(xing)具有更好的(de)諧波(bo)(bo)頻譜(pu)，因此RSVG可稱(cheng)為(wei)“完美無諧波(bo)(bo)變(bian)(bian)流器(qi)”。
