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)壓無功(gong)(gong)補(bu)償裝置(zhi)（簡(jian)稱RSVG），采(cai)用(yong)(yong)瞬時無功(gong)(gong)功(gong)(gong)率理論的(de)(de)無功(gong)(gong)檢(jian)測方式，以功(gong)(gong)率因數(shu)、網側電(dian)(dian)(dian)壓作為控制目標，動(dong)態跟蹤電(dian)(dian)(dian)網電(dian)(dian)(dian)能(neng)(neng)相關(guan)指標的(de)(de)變化(hua)，并根據變化(hua)情況調節無功(gong)(gong)輸出，實現電(dian)(dian)(dian)網的(de)(de)高(gao)(gao)電(dian)(dian)(dian)能(neng)(neng)質量運行。控制器采(cai)用(yong)(yong)高(gao)(gao)速DSP和(he)FPGA，實現全(quan)數(shu)字化(hua)控制，電(dian)(dian)(dian)壓電(dian)(dian)(dian)流數(shu)字閉環(huan)和(he)載波(bo)移相技(ji)術，信號采(cai)用(yong)(yong)光纖傳輸，實現了高(gao)(gao)壓隔離(li)，提高(gao)(gao)了整機的(de)(de)穩定性(xing)和(he)可靠性(xing)。采(cai)用(yong)(yong)IGBT組(zu)成的(de)(de)H橋功(gong)(gong)率模塊鏈作為逆(ni)變主(zhu)電(dian)(dian)(dian)路(lu)的(de)(de)結(jie)構形式，拓(tuo)撲簡(jian)單(dan)，性(xing)能(neng)(neng)可靠，并輔助以小容量儲能(neng)(neng)元件(jian)，整機輸出電(dian)(dian)(dian)壓由多個電(dian)(dian)(dian)平(ping)臺階合成階梯波(bo)，經過輸出電(dian)(dian)(dian)抗濾波(bo)后(hou)正弦度好。RSVG由于輸出電(dian)(dian)(dian)壓電(dian)(dian)(dian)平(ping)數(shu)多，輸出波(bo)形具有更好的(de)(de)諧波(bo)頻譜，因此RSVG可稱為“完美無諧波(bo)變流器”。
