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)無(wu)功(gong)(gong)補(bu)償裝置（簡稱(cheng)RSVG），采用瞬時(shi)無(wu)功(gong)(gong)功(gong)(gong)率(lv)理論的(de)(de)無(wu)功(gong)(gong)檢測(ce)方式，以功(gong)(gong)率(lv)因數(shu)(shu)、網(wang)側電(dian)(dian)壓(ya)作為控(kong)制目標，動(dong)態跟蹤電(dian)(dian)網(wang)電(dian)(dian)能(neng)相(xiang)關(guan)指標的(de)(de)變(bian)(bian)(bian)化，并根據變(bian)(bian)(bian)化情況調節無(wu)功(gong)(gong)輸出，實(shi)現電(dian)(dian)網(wang)的(de)(de)高電(dian)(dian)能(neng)質(zhi)量(liang)運行。控(kong)制器采用高速DSP和FPGA，實(shi)現全數(shu)(shu)字化控(kong)制，電(dian)(dian)壓(ya)電(dian)(dian)流數(shu)(shu)字閉環和載波移相(xiang)技術，信號采用光(guang)纖傳(chuan)輸，實(shi)現了(le)(le)高壓(ya)隔離，提高了(le)(le)整機(ji)的(de)(de)穩定性和可(ke)靠性。采用IGBT組成的(de)(de)H橋(qiao)功(gong)(gong)率(lv)模塊(kuai)鏈(lian)作為逆變(bian)(bian)(bian)主電(dian)(dian)路的(de)(de)結構形(xing)式，拓(tuo)撲簡單，性能(neng)可(ke)靠，并輔助以小容量(liang)儲能(neng)元件，整機(ji)輸出電(dian)(dian)壓(ya)由多(duo)個(ge)電(dian)(dian)平臺階合成階梯波，經(jing)過輸出電(dian)(dian)抗濾波后正弦(xian)度好(hao)。RSVG由于輸出電(dian)(dian)壓(ya)電(dian)(dian)平數(shu)(shu)多(duo)，輸出波形(xing)具有更好(hao)的(de)(de)諧波頻譜，因此RSVG可(ke)稱(cheng)為“完(wan)美無(wu)諧波變(bian)(bian)(bian)流器”。
