RSVG高壓靜止無功發生器——35kV直掛SVG（水冷戶外）

榮信興業高壓(ya)無(wu)功(gong)(gong)補償裝置(zhi)（簡稱RSVG），采用瞬(shun)時無(wu)功(gong)(gong)功(gong)(gong)率理論的(de)(de)無(wu)功(gong)(gong)檢測方(fang)式，以功(gong)(gong)率因數(shu)、網(wang)側電(dian)(dian)(dian)(dian)(dian)壓(ya)作為(wei)控制目標，動態跟蹤電(dian)(dian)(dian)(dian)(dian)網(wang)電(dian)(dian)(dian)(dian)(dian)能相關(guan)指標的(de)(de)變化，并根據變化情況調節無(wu)功(gong)(gong)輸(shu)(shu)出，實(shi)(shi)現(xian)電(dian)(dian)(dian)(dian)(dian)網(wang)的(de)(de)高電(dian)(dian)(dian)(dian)(dian)能質量運行。控制器采用高速DSP和(he)FPGA，實(shi)(shi)現(xian)全數(shu)字化控制，電(dian)(dian)(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)(dian)(dian)流數(shu)字閉環和(he)載(zai)波(bo)移相技(ji)術，信號采用光纖傳輸(shu)(shu)，實(shi)(shi)現(xian)了高壓(ya)隔離(li)，提高了整機的(de)(de)穩定(ding)性(xing)和(he)可(ke)(ke)靠性(xing)。采用IGBT組成的(de)(de)H橋功(gong)(gong)率模塊鏈作為(wei)逆變主(zhu)電(dian)(dian)(dian)(dian)(dian)路的(de)(de)結構(gou)形式，拓(tuo)撲簡單，性(xing)能可(ke)(ke)靠，并輔(fu)助以小容量儲能元件(jian)，整機輸(shu)(shu)出電(dian)(dian)(dian)(dian)(dian)壓(ya)由多個(ge)電(dian)(dian)(dian)(dian)(dian)平臺(tai)階(jie)合成階(jie)梯波(bo)，經過(guo)輸(shu)(shu)出電(dian)(dian)(dian)(dian)(dian)抗濾波(bo)后正(zheng)弦度好。RSVG由于(yu)輸(shu)(shu)出電(dian)(dian)(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)(dian)(dian)平數(shu)多，輸(shu)(shu)出波(bo)形具有更好的(de)(de)諧(xie)波(bo)頻譜，因此(ci)RSVG可(ke)(ke)稱為(wei)“完美無(wu)諧(xie)波(bo)變流器”。
