RSVG高壓靜止無功發生器——35kV直掛SVG（水冷戶外）

榮信(xin)興(xing)業高(gao)壓(ya)無(wu)(wu)(wu)功(gong)補償裝(zhuang)置（簡(jian)稱RSVG），采用瞬時無(wu)(wu)(wu)功(gong)功(gong)率(lv)(lv)理論的(de)(de)(de)無(wu)(wu)(wu)功(gong)檢(jian)測(ce)方式，以功(gong)率(lv)(lv)因數(shu)(shu)、網側電(dian)(dian)(dian)壓(ya)作為(wei)(wei)控制目(mu)標(biao)(biao)，動態跟蹤電(dian)(dian)(dian)網電(dian)(dian)(dian)能(neng)相(xiang)關指標(biao)(biao)的(de)(de)(de)變(bian)(bian)化，并根據變(bian)(bian)化情況(kuang)調節無(wu)(wu)(wu)功(gong)輸(shu)出(chu)(chu)，實現電(dian)(dian)(dian)網的(de)(de)(de)高(gao)電(dian)(dian)(dian)能(neng)質量運行。控制器采用高(gao)速(su)DSP和(he)FPGA，實現全數(shu)(shu)字化控制，電(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)流(liu)數(shu)(shu)字閉環和(he)載波(bo)(bo)(bo)移相(xiang)技(ji)術，信(xin)號采用光纖(xian)傳輸(shu)，實現了高(gao)壓(ya)隔離(li)，提高(gao)了整(zheng)機的(de)(de)(de)穩定性和(he)可靠性。采用IGBT組(zu)成(cheng)的(de)(de)(de)H橋功(gong)率(lv)(lv)模塊鏈作為(wei)(wei)逆變(bian)(bian)主電(dian)(dian)(dian)路(lu)的(de)(de)(de)結構形式，拓撲簡(jian)單，性能(neng)可靠，并輔(fu)助以小容量儲能(neng)元件(jian)，整(zheng)機輸(shu)出(chu)(chu)電(dian)(dian)(dian)壓(ya)由多個電(dian)(dian)(dian)平臺階合成(cheng)階梯波(bo)(bo)(bo)，經過輸(shu)出(chu)(chu)電(dian)(dian)(dian)抗濾波(bo)(bo)(bo)后正弦度好。RSVG由于輸(shu)出(chu)(chu)電(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)平數(shu)(shu)多，輸(shu)出(chu)(chu)波(bo)(bo)(bo)形具有更好的(de)(de)(de)諧波(bo)(bo)(bo)頻(pin)譜(pu)，因此RSVG可稱為(wei)(wei)“完美無(wu)(wu)(wu)諧波(bo)(bo)(bo)變(bian)(bian)流(liu)器”。
