RSVG高壓靜止無功發生器——35kV直掛SVG（水冷戶外）

榮信興業高(gao)(gao)壓(ya)(ya)無(wu)功(gong)(gong)(gong)補(bu)償裝置（簡(jian)稱(cheng)RSVG），采(cai)用瞬時無(wu)功(gong)(gong)(gong)功(gong)(gong)(gong)率理論的(de)無(wu)功(gong)(gong)(gong)檢(jian)測方式，以(yi)功(gong)(gong)(gong)率因數、網側電(dian)(dian)壓(ya)(ya)作為(wei)控(kong)制目(mu)標(biao)，動態跟蹤電(dian)(dian)網電(dian)(dian)能(neng)(neng)相關指標(biao)的(de)變(bian)化，并根據(ju)變(bian)化情(qing)況調(diao)節無(wu)功(gong)(gong)(gong)輸(shu)(shu)出(chu)(chu)，實(shi)現(xian)電(dian)(dian)網的(de)高(gao)(gao)電(dian)(dian)能(neng)(neng)質量(liang)運行。控(kong)制器采(cai)用高(gao)(gao)速DSP和FPGA，實(shi)現(xian)全數字化控(kong)制，電(dian)(dian)壓(ya)(ya)電(dian)(dian)流(liu)數字閉環和載波(bo)移相技術(shu)，信號采(cai)用光纖傳輸(shu)(shu)，實(shi)現(xian)了高(gao)(gao)壓(ya)(ya)隔離，提高(gao)(gao)了整(zheng)(zheng)機(ji)的(de)穩定(ding)性(xing)和可(ke)靠(kao)性(xing)。采(cai)用IGBT組成的(de)H橋功(gong)(gong)(gong)率模塊鏈作為(wei)逆(ni)變(bian)主電(dian)(dian)路的(de)結構形式，拓撲簡(jian)單(dan)，性(xing)能(neng)(neng)可(ke)靠(kao)，并輔助以(yi)小容(rong)量(liang)儲能(neng)(neng)元件，整(zheng)(zheng)機(ji)輸(shu)(shu)出(chu)(chu)電(dian)(dian)壓(ya)(ya)由多個電(dian)(dian)平臺階合(he)成階梯波(bo)，經過輸(shu)(shu)出(chu)(chu)電(dian)(dian)抗濾波(bo)后(hou)正弦度好。RSVG由于輸(shu)(shu)出(chu)(chu)電(dian)(dian)壓(ya)(ya)電(dian)(dian)平數多，輸(shu)(shu)出(chu)(chu)波(bo)形具有更好的(de)諧(xie)(xie)波(bo)頻譜，因此RSVG可(ke)稱(cheng)為(wei)“完美(mei)無(wu)諧(xie)(xie)波(bo)變(bian)流(liu)器”。
