RSVG高壓靜止無功發生器——35kV直掛SVG（水冷戶外）

榮信興業高(gao)壓(ya)(ya)(ya)無功(gong)補償裝(zhuang)置（簡稱(cheng)RSVG），采(cai)用(yong)瞬時無功(gong)功(gong)率(lv)理論的(de)無功(gong)檢測(ce)方(fang)式，以功(gong)率(lv)因(yin)數、網側電(dian)(dian)壓(ya)(ya)(ya)作為(wei)控制(zhi)目標，動(dong)態跟蹤電(dian)(dian)網電(dian)(dian)能相關指標的(de)變(bian)化，并根據變(bian)化情況(kuang)調(diao)節無功(gong)輸(shu)出，實現(xian)電(dian)(dian)網的(de)高(gao)電(dian)(dian)能質量運(yun)行。控制(zhi)器采(cai)用(yong)高(gao)速DSP和(he)(he)FPGA，實現(xian)全數字化控制(zhi)，電(dian)(dian)壓(ya)(ya)(ya)電(dian)(dian)流數字閉環和(he)(he)載(zai)波(bo)(bo)移相技術，信號采(cai)用(yong)光纖傳輸(shu)，實現(xian)了高(gao)壓(ya)(ya)(ya)隔(ge)離(li)，提高(gao)了整機的(de)穩定性(xing)和(he)(he)可靠性(xing)。采(cai)用(yong)IGBT組(zu)成的(de)H橋功(gong)率(lv)模(mo)塊鏈作為(wei)逆(ni)變(bian)主(zhu)電(dian)(dian)路(lu)的(de)結構形(xing)式，拓撲簡單，性(xing)能可靠，并輔(fu)助以小(xiao)容(rong)量儲能元件，整機輸(shu)出電(dian)(dian)壓(ya)(ya)(ya)由多個電(dian)(dian)平(ping)臺階合成階梯波(bo)(bo)，經(jing)過(guo)輸(shu)出電(dian)(dian)抗濾波(bo)(bo)后正弦(xian)度好。RSVG由于輸(shu)出電(dian)(dian)壓(ya)(ya)(ya)電(dian)(dian)平(ping)數多，輸(shu)出波(bo)(bo)形(xing)具有更好的(de)諧波(bo)(bo)頻譜，因(yin)此(ci)RSVG可稱(cheng)為(wei)“完美無諧波(bo)(bo)變(bian)流器”。
