RSVG高壓靜止無功發生器——35kV直掛SVG（水冷戶外）

榮(rong)信興業高(gao)壓(ya)無(wu)功(gong)(gong)(gong)補償(chang)裝置（簡稱(cheng)RSVG），采(cai)(cai)用(yong)瞬時無(wu)功(gong)(gong)(gong)功(gong)(gong)(gong)率(lv)理論的無(wu)功(gong)(gong)(gong)檢測方式(shi)，以(yi)功(gong)(gong)(gong)率(lv)因數(shu)(shu)、網(wang)側電壓(ya)作為控制(zhi)目標，動(dong)態跟蹤(zong)電網(wang)電能(neng)相關指標的變(bian)化(hua)(hua)，并根據變(bian)化(hua)(hua)情況調節無(wu)功(gong)(gong)(gong)輸(shu)出(chu)，實(shi)(shi)現電網(wang)的高(gao)電能(neng)質(zhi)量(liang)運行(xing)。控制(zhi)器采(cai)(cai)用(yong)高(gao)速DSP和FPGA，實(shi)(shi)現全數(shu)(shu)字化(hua)(hua)控制(zhi)，電壓(ya)電流(liu)數(shu)(shu)字閉環和載(zai)波(bo)移相技術，信號采(cai)(cai)用(yong)光纖傳輸(shu)，實(shi)(shi)現了高(gao)壓(ya)隔離，提高(gao)了整機(ji)(ji)的穩定性(xing)和可靠性(xing)。采(cai)(cai)用(yong)IGBT組成的H橋功(gong)(gong)(gong)率(lv)模(mo)塊鏈作為逆(ni)變(bian)主電路的結構形式(shi)，拓撲簡單，性(xing)能(neng)可靠，并輔助(zhu)以(yi)小容量(liang)儲能(neng)元件(jian)，整機(ji)(ji)輸(shu)出(chu)電壓(ya)由(you)多(duo)個(ge)電平臺階合成階梯波(bo)，經(jing)過輸(shu)出(chu)電抗(kang)濾波(bo)后正弦度好。RSVG由(you)于輸(shu)出(chu)電壓(ya)電平數(shu)(shu)多(duo)，輸(shu)出(chu)波(bo)形具有更(geng)好的諧(xie)波(bo)頻譜，因此RSVG可稱(cheng)為“完美無(wu)諧(xie)波(bo)變(bian)流(liu)器”。
