RSVG高壓靜止無功發生器——35kV直掛SVG（水冷戶外）

榮信(xin)興業(ye)高(gao)壓(ya)(ya)無功(gong)(gong)補償(chang)裝置（簡(jian)稱RSVG），采用(yong)(yong)(yong)瞬時(shi)無功(gong)(gong)功(gong)(gong)率理論的無功(gong)(gong)檢測方式，以功(gong)(gong)率因數、網側電(dian)(dian)(dian)壓(ya)(ya)作(zuo)為(wei)控(kong)制(zhi)目標，動(dong)態跟(gen)蹤電(dian)(dian)(dian)網電(dian)(dian)(dian)能(neng)相(xiang)關(guan)指標的變(bian)化，并根(gen)據變(bian)化情況調節無功(gong)(gong)輸出，實(shi)現電(dian)(dian)(dian)網的高(gao)電(dian)(dian)(dian)能(neng)質量運行(xing)。控(kong)制(zhi)器采用(yong)(yong)(yong)高(gao)速DSP和FPGA，實(shi)現全數字(zi)化控(kong)制(zhi)，電(dian)(dian)(dian)壓(ya)(ya)電(dian)(dian)(dian)流數字(zi)閉(bi)環和載(zai)波(bo)移相(xiang)技術，信(xin)號采用(yong)(yong)(yong)光纖傳輸，實(shi)現了高(gao)壓(ya)(ya)隔離，提高(gao)了整機的穩定性(xing)和可靠(kao)性(xing)。采用(yong)(yong)(yong)IGBT組(zu)成(cheng)(cheng)的H橋功(gong)(gong)率模塊鏈(lian)作(zuo)為(wei)逆變(bian)主電(dian)(dian)(dian)路(lu)的結構形式，拓(tuo)撲(pu)簡(jian)單(dan)，性(xing)能(neng)可靠(kao)，并輔助以小容(rong)量儲能(neng)元件，整機輸出電(dian)(dian)(dian)壓(ya)(ya)由多個電(dian)(dian)(dian)平(ping)臺階(jie)合成(cheng)(cheng)階(jie)梯(ti)波(bo)，經過輸出電(dian)(dian)(dian)抗濾波(bo)后正(zheng)弦(xian)度好(hao)。RSVG由于輸出電(dian)(dian)(dian)壓(ya)(ya)電(dian)(dian)(dian)平(ping)數多，輸出波(bo)形具有更好(hao)的諧(xie)波(bo)頻譜，因此RSVG可稱為(wei)“完美(mei)無諧(xie)波(bo)變(bian)流器”。
