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)壓無(wu)功(gong)(gong)補償裝置（簡(jian)稱RSVG），采用(yong)(yong)(yong)瞬時無(wu)功(gong)(gong)功(gong)(gong)率理論的(de)無(wu)功(gong)(gong)檢測方式，以(yi)(yi)功(gong)(gong)率因(yin)數(shu)(shu)、網側(ce)電(dian)(dian)(dian)(dian)壓作為(wei)控(kong)(kong)制目標(biao)，動態跟蹤(zong)電(dian)(dian)(dian)(dian)網電(dian)(dian)(dian)(dian)能(neng)(neng)相關(guan)指標(biao)的(de)變化(hua)，并根據變化(hua)情況調節無(wu)功(gong)(gong)輸(shu)出，實現電(dian)(dian)(dian)(dian)網的(de)高(gao)電(dian)(dian)(dian)(dian)能(neng)(neng)質(zhi)量運行。控(kong)(kong)制器采用(yong)(yong)(yong)高(gao)速DSP和FPGA，實現全(quan)數(shu)(shu)字(zi)化(hua)控(kong)(kong)制，電(dian)(dian)(dian)(dian)壓電(dian)(dian)(dian)(dian)流數(shu)(shu)字(zi)閉環和載波(bo)(bo)移(yi)相技術，信(xin)號采用(yong)(yong)(yong)光纖傳輸(shu)，實現了(le)高(gao)壓隔離(li)，提高(gao)了(le)整(zheng)機的(de)穩(wen)定性(xing)(xing)和可靠性(xing)(xing)。采用(yong)(yong)(yong)IGBT組成(cheng)的(de)H橋功(gong)(gong)率模塊鏈作為(wei)逆(ni)變主電(dian)(dian)(dian)(dian)路的(de)結(jie)構形式，拓撲簡(jian)單，性(xing)(xing)能(neng)(neng)可靠，并輔助以(yi)(yi)小容量儲能(neng)(neng)元件，整(zheng)機輸(shu)出電(dian)(dian)(dian)(dian)壓由多個電(dian)(dian)(dian)(dian)平臺階合成(cheng)階梯波(bo)(bo)，經過輸(shu)出電(dian)(dian)(dian)(dian)抗濾(lv)波(bo)(bo)后(hou)正弦度好。RSVG由于輸(shu)出電(dian)(dian)(dian)(dian)壓電(dian)(dian)(dian)(dian)平數(shu)(shu)多，輸(shu)出波(bo)(bo)形具有更(geng)好的(de)諧(xie)波(bo)(bo)頻譜，因(yin)此RSVG可稱為(wei)“完美無(wu)諧(xie)波(bo)(bo)變流器”。
