RSVG高壓靜止無功發生器——35kV直掛SVG（水冷戶外）

榮信興業高(gao)(gao)壓(ya)(ya)無(wu)(wu)功(gong)(gong)補償裝置（簡稱(cheng)(cheng)RSVG），采用瞬時無(wu)(wu)功(gong)(gong)功(gong)(gong)率理(li)論的(de)無(wu)(wu)功(gong)(gong)檢測方式，以功(gong)(gong)率因數、網(wang)側(ce)電(dian)(dian)(dian)壓(ya)(ya)作為控(kong)(kong)制目標，動態跟(gen)蹤(zong)電(dian)(dian)(dian)網(wang)電(dian)(dian)(dian)能(neng)相關(guan)指標的(de)變(bian)化(hua)，并根據變(bian)化(hua)情(qing)況(kuang)調節(jie)無(wu)(wu)功(gong)(gong)輸(shu)(shu)(shu)出(chu)，實(shi)現電(dian)(dian)(dian)網(wang)的(de)高(gao)(gao)電(dian)(dian)(dian)能(neng)質量運行。控(kong)(kong)制器(qi)采用高(gao)(gao)速(su)DSP和(he)FPGA，實(shi)現全(quan)數字化(hua)控(kong)(kong)制，電(dian)(dian)(dian)壓(ya)(ya)電(dian)(dian)(dian)流(liu)數字閉(bi)環和(he)載波(bo)(bo)移相技術，信號(hao)采用光纖傳輸(shu)(shu)(shu)，實(shi)現了高(gao)(gao)壓(ya)(ya)隔離，提高(gao)(gao)了整機的(de)穩定性和(he)可靠性。采用IGBT組成(cheng)的(de)H橋(qiao)功(gong)(gong)率模塊鏈作為逆變(bian)主電(dian)(dian)(dian)路的(de)結構(gou)形(xing)(xing)式，拓撲簡單，性能(neng)可靠，并輔助(zhu)以小容(rong)量儲能(neng)元件，整機輸(shu)(shu)(shu)出(chu)電(dian)(dian)(dian)壓(ya)(ya)由(you)多個(ge)電(dian)(dian)(dian)平臺階合成(cheng)階梯(ti)波(bo)(bo)，經(jing)過輸(shu)(shu)(shu)出(chu)電(dian)(dian)(dian)抗濾波(bo)(bo)后正弦度(du)好。RSVG由(you)于輸(shu)(shu)(shu)出(chu)電(dian)(dian)(dian)壓(ya)(ya)電(dian)(dian)(dian)平數多，輸(shu)(shu)(shu)出(chu)波(bo)(bo)形(xing)(xing)具有(you)更好的(de)諧(xie)波(bo)(bo)頻譜，因此(ci)RSVG可稱(cheng)(cheng)為“完(wan)美無(wu)(wu)諧(xie)波(bo)(bo)變(bian)流(liu)器(qi)”。
