RSVG高壓靜止無功發生器——35kV直掛SVG（水冷戶外）

榮(rong)信(xin)(xin)興業高(gao)壓(ya)無(wu)(wu)功(gong)(gong)補償裝置（簡稱RSVG），采(cai)用瞬時(shi)無(wu)(wu)功(gong)(gong)功(gong)(gong)率(lv)(lv)理論的無(wu)(wu)功(gong)(gong)檢測方(fang)式，以功(gong)(gong)率(lv)(lv)因(yin)數、網側電(dian)(dian)(dian)(dian)壓(ya)作(zuo)(zuo)為(wei)控制目標，動態跟(gen)蹤(zong)電(dian)(dian)(dian)(dian)網電(dian)(dian)(dian)(dian)能(neng)相(xiang)關指標的變化，并根據變化情況調節(jie)無(wu)(wu)功(gong)(gong)輸(shu)(shu)出(chu)，實現電(dian)(dian)(dian)(dian)網的高(gao)電(dian)(dian)(dian)(dian)能(neng)質量運行。控制器采(cai)用高(gao)速DSP和FPGA，實現全數字化控制，電(dian)(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)(dian)流數字閉環和載波(bo)(bo)移相(xiang)技(ji)術(shu)，信(xin)(xin)號(hao)采(cai)用光纖傳輸(shu)(shu)，實現了高(gao)壓(ya)隔離(li)，提(ti)高(gao)了整機(ji)的穩定性和可靠性。采(cai)用IGBT組成的H橋功(gong)(gong)率(lv)(lv)模塊鏈作(zuo)(zuo)為(wei)逆變主(zhu)電(dian)(dian)(dian)(dian)路(lu)的結構形式，拓撲簡單，性能(neng)可靠，并輔助以小容量儲能(neng)元件(jian)，整機(ji)輸(shu)(shu)出(chu)電(dian)(dian)(dian)(dian)壓(ya)由多(duo)個(ge)電(dian)(dian)(dian)(dian)平臺階合(he)成階梯波(bo)(bo)，經(jing)過(guo)輸(shu)(shu)出(chu)電(dian)(dian)(dian)(dian)抗濾波(bo)(bo)后正(zheng)弦度(du)好。RSVG由于輸(shu)(shu)出(chu)電(dian)(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)(dian)平數多(duo)，輸(shu)(shu)出(chu)波(bo)(bo)形具有更好的諧波(bo)(bo)頻(pin)譜(pu)，因(yin)此RSVG可稱為(wei)“完美無(wu)(wu)諧波(bo)(bo)變流器”。
