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(gong)(gong)補(bu)償裝置（簡(jian)(jian)稱(cheng)RSVG），采用瞬時(shi)無功(gong)(gong)功(gong)(gong)率(lv)理論的(de)(de)(de)無功(gong)(gong)檢測方式(shi)，以功(gong)(gong)率(lv)因數(shu)、網(wang)側電(dian)(dian)壓(ya)(ya)作(zuo)為控(kong)制目標，動(dong)態跟蹤電(dian)(dian)網(wang)電(dian)(dian)能相關(guan)指標的(de)(de)(de)變(bian)化，并(bing)根據變(bian)化情況調節無功(gong)(gong)輸(shu)(shu)(shu)出，實現電(dian)(dian)網(wang)的(de)(de)(de)高(gao)電(dian)(dian)能質量運行。控(kong)制器采用高(gao)速DSP和FPGA，實現全數(shu)字(zi)化控(kong)制，電(dian)(dian)壓(ya)(ya)電(dian)(dian)流(liu)數(shu)字(zi)閉(bi)環和載波(bo)移相技術(shu)，信號(hao)采用光(guang)纖傳輸(shu)(shu)(shu)，實現了高(gao)壓(ya)(ya)隔離，提(ti)高(gao)了整機的(de)(de)(de)穩(wen)定性(xing)(xing)和可(ke)靠(kao)性(xing)(xing)。采用IGBT組成(cheng)(cheng)的(de)(de)(de)H橋功(gong)(gong)率(lv)模塊(kuai)鏈作(zuo)為逆變(bian)主電(dian)(dian)路的(de)(de)(de)結構(gou)形式(shi)，拓撲簡(jian)(jian)單，性(xing)(xing)能可(ke)靠(kao)，并(bing)輔助以小(xiao)容量儲能元件(jian)，整機輸(shu)(shu)(shu)出電(dian)(dian)壓(ya)(ya)由多個電(dian)(dian)平臺階(jie)合(he)成(cheng)(cheng)階(jie)梯波(bo)，經過輸(shu)(shu)(shu)出電(dian)(dian)抗濾波(bo)后正弦(xian)度(du)好。RSVG由于(yu)輸(shu)(shu)(shu)出電(dian)(dian)壓(ya)(ya)電(dian)(dian)平數(shu)多，輸(shu)(shu)(shu)出波(bo)形具(ju)有更好的(de)(de)(de)諧(xie)波(bo)頻譜，因此RSVG可(ke)稱(cheng)為“完美無諧(xie)波(bo)變(bian)流(liu)器”。
