RSVG高壓靜止無功發生器——35kV直掛SVG（水冷戶外）

榮信興(xing)業高(gao)(gao)壓(ya)無功(gong)(gong)補(bu)償裝置(zhi)（簡(jian)稱(cheng)RSVG），采(cai)用(yong)瞬(shun)時無功(gong)(gong)功(gong)(gong)率(lv)理論的(de)(de)無功(gong)(gong)檢(jian)測方式，以功(gong)(gong)率(lv)因數、網側電(dian)(dian)壓(ya)作(zuo)為(wei)控(kong)制目標(biao)，動(dong)態(tai)跟蹤(zong)電(dian)(dian)網電(dian)(dian)能(neng)相關指標(biao)的(de)(de)變(bian)(bian)化(hua)，并根據變(bian)(bian)化(hua)情況調節無功(gong)(gong)輸(shu)(shu)(shu)出(chu)，實現電(dian)(dian)網的(de)(de)高(gao)(gao)電(dian)(dian)能(neng)質量(liang)運行(xing)。控(kong)制器采(cai)用(yong)高(gao)(gao)速DSP和FPGA，實現全數字化(hua)控(kong)制，電(dian)(dian)壓(ya)電(dian)(dian)流數字閉(bi)環和載波(bo)(bo)移相技術(shu)，信號(hao)采(cai)用(yong)光(guang)纖傳輸(shu)(shu)(shu)，實現了(le)高(gao)(gao)壓(ya)隔離，提高(gao)(gao)了(le)整機的(de)(de)穩定性和可(ke)靠性。采(cai)用(yong)IGBT組成(cheng)的(de)(de)H橋功(gong)(gong)率(lv)模(mo)塊鏈作(zuo)為(wei)逆變(bian)(bian)主電(dian)(dian)路的(de)(de)結(jie)構形式，拓撲簡(jian)單，性能(neng)可(ke)靠，并輔(fu)助以小容量(liang)儲能(neng)元件(jian)，整機輸(shu)(shu)(shu)出(chu)電(dian)(dian)壓(ya)由多(duo)個電(dian)(dian)平臺階(jie)合成(cheng)階(jie)梯波(bo)(bo)，經(jing)過輸(shu)(shu)(shu)出(chu)電(dian)(dian)抗濾波(bo)(bo)后正弦度好(hao)。RSVG由于輸(shu)(shu)(shu)出(chu)電(dian)(dian)壓(ya)電(dian)(dian)平數多(duo)，輸(shu)(shu)(shu)出(chu)波(bo)(bo)形具有更好(hao)的(de)(de)諧(xie)(xie)波(bo)(bo)頻譜，因此RSVG可(ke)稱(cheng)為(wei)“完(wan)美無諧(xie)(xie)波(bo)(bo)變(bian)(bian)流器”。
