RSVG高壓靜止無功發生器——35kV直掛SVG（水冷戶外）

榮信(xin)興業(ye)高(gao)壓(ya)無功(gong)補償裝置（簡稱RSVG），采(cai)用瞬(shun)時(shi)無功(gong)功(gong)率理(li)論的(de)無功(gong)檢測方(fang)式(shi)，以功(gong)率因(yin)數、網(wang)側電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)作(zuo)(zuo)為控制目標，動(dong)態跟(gen)蹤電(dian)(dian)(dian)(dian)(dian)(dian)網(wang)電(dian)(dian)(dian)(dian)(dian)(dian)能(neng)(neng)相(xiang)關(guan)指標的(de)變(bian)化，并根據變(bian)化情況調(diao)節無功(gong)輸(shu)(shu)出，實現電(dian)(dian)(dian)(dian)(dian)(dian)網(wang)的(de)高(gao)電(dian)(dian)(dian)(dian)(dian)(dian)能(neng)(neng)質量(liang)運行。控制器采(cai)用高(gao)速DSP和(he)(he)FPGA，實現全數字化控制，電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)流數字閉環和(he)(he)載(zai)波(bo)移相(xiang)技術(shu)，信(xin)號采(cai)用光(guang)纖(xian)傳輸(shu)(shu)，實現了(le)高(gao)壓(ya)隔離，提高(gao)了(le)整(zheng)機的(de)穩定性和(he)(he)可靠性。采(cai)用IGBT組成(cheng)的(de)H橋功(gong)率模(mo)塊鏈作(zuo)(zuo)為逆變(bian)主電(dian)(dian)(dian)(dian)(dian)(dian)路的(de)結(jie)構形式(shi)，拓撲(pu)簡單，性能(neng)(neng)可靠，并輔助以小容量(liang)儲能(neng)(neng)元件，整(zheng)機輸(shu)(shu)出電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)由多個(ge)電(dian)(dian)(dian)(dian)(dian)(dian)平臺階合成(cheng)階梯波(bo)，經(jing)過輸(shu)(shu)出電(dian)(dian)(dian)(dian)(dian)(dian)抗濾波(bo)后正弦度好(hao)。RSVG由于輸(shu)(shu)出電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)平數多，輸(shu)(shu)出波(bo)形具有更好(hao)的(de)諧(xie)波(bo)頻譜，因(yin)此RSVG可稱為“完美無諧(xie)波(bo)變(bian)流器”。
