RSVG高壓靜止無功發生器——35kV直掛SVG（水冷戶外）

榮信(xin)興業高(gao)壓(ya)無(wu)功(gong)(gong)補償(chang)裝置（簡稱RSVG），采用(yong)(yong)瞬時無(wu)功(gong)(gong)功(gong)(gong)率(lv)理論的(de)無(wu)功(gong)(gong)檢測(ce)方式，以(yi)功(gong)(gong)率(lv)因(yin)數、網側電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)作為控制目(mu)標(biao)(biao)，動態跟蹤電(dian)(dian)(dian)(dian)(dian)(dian)網電(dian)(dian)(dian)(dian)(dian)(dian)能(neng)相關指標(biao)(biao)的(de)變(bian)化，并根(gen)據變(bian)化情況調節無(wu)功(gong)(gong)輸出，實現電(dian)(dian)(dian)(dian)(dian)(dian)網的(de)高(gao)電(dian)(dian)(dian)(dian)(dian)(dian)能(neng)質量(liang)運(yun)行。控制器采用(yong)(yong)高(gao)速DSP和FPGA，實現全數字(zi)化控制，電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)流數字(zi)閉環和載波移(yi)相技(ji)術(shu)，信(xin)號(hao)采用(yong)(yong)光纖傳(chuan)輸，實現了(le)(le)高(gao)壓(ya)隔離(li)，提高(gao)了(le)(le)整機的(de)穩定性和可靠性。采用(yong)(yong)IGBT組成(cheng)的(de)H橋功(gong)(gong)率(lv)模(mo)塊鏈作為逆變(bian)主電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)的(de)結構形式，拓撲簡單，性能(neng)可靠，并輔助以(yi)小容量(liang)儲能(neng)元件，整機輸出電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)由(you)多(duo)個電(dian)(dian)(dian)(dian)(dian)(dian)平臺階(jie)(jie)合成(cheng)階(jie)(jie)梯波，經過輸出電(dian)(dian)(dian)(dian)(dian)(dian)抗(kang)濾波后正弦度好。RSVG由(you)于輸出電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)平數多(duo)，輸出波形具有更好的(de)諧波頻譜，因(yin)此(ci)RSVG可稱為“完美無(wu)諧波變(bian)流器”。
