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)(gao)壓(ya)(ya)無(wu)功(gong)(gong)補(bu)償裝置（簡(jian)稱RSVG），采(cai)(cai)用瞬時無(wu)功(gong)(gong)功(gong)(gong)率理論的(de)(de)無(wu)功(gong)(gong)檢測方(fang)式，以(yi)功(gong)(gong)率因數(shu)(shu)、網(wang)(wang)側電(dian)(dian)(dian)壓(ya)(ya)作為(wei)控制目(mu)標(biao)，動態跟蹤(zong)電(dian)(dian)(dian)網(wang)(wang)電(dian)(dian)(dian)能(neng)相關(guan)指標(biao)的(de)(de)變化(hua)，并根據變化(hua)情況調節無(wu)功(gong)(gong)輸出(chu)，實(shi)(shi)現(xian)電(dian)(dian)(dian)網(wang)(wang)的(de)(de)高(gao)(gao)電(dian)(dian)(dian)能(neng)質量運行。控制器(qi)采(cai)(cai)用高(gao)(gao)速DSP和(he)FPGA，實(shi)(shi)現(xian)全數(shu)(shu)字(zi)化(hua)控制，電(dian)(dian)(dian)壓(ya)(ya)電(dian)(dian)(dian)流數(shu)(shu)字(zi)閉環(huan)和(he)載波(bo)移相技術，信(xin)號采(cai)(cai)用光纖傳輸，實(shi)(shi)現(xian)了(le)高(gao)(gao)壓(ya)(ya)隔離，提高(gao)(gao)了(le)整機(ji)的(de)(de)穩定性和(he)可(ke)(ke)靠性。采(cai)(cai)用IGBT組成的(de)(de)H橋功(gong)(gong)率模塊鏈作為(wei)逆變主電(dian)(dian)(dian)路(lu)的(de)(de)結構形(xing)式，拓撲簡(jian)單，性能(neng)可(ke)(ke)靠，并輔助以(yi)小容量儲能(neng)元件(jian)，整機(ji)輸出(chu)電(dian)(dian)(dian)壓(ya)(ya)由(you)(you)多(duo)個(ge)電(dian)(dian)(dian)平(ping)(ping)臺(tai)階合成階梯波(bo)，經過(guo)輸出(chu)電(dian)(dian)(dian)抗濾波(bo)后(hou)正弦度好(hao)。RSVG由(you)(you)于輸出(chu)電(dian)(dian)(dian)壓(ya)(ya)電(dian)(dian)(dian)平(ping)(ping)數(shu)(shu)多(duo)，輸出(chu)波(bo)形(xing)具有更好(hao)的(de)(de)諧波(bo)頻譜，因此RSVG可(ke)(ke)稱為(wei)“完美無(wu)諧波(bo)變流器(qi)”。
