RSVG高壓靜止無功發生器——35kV直掛SVG（水冷戶外）

榮信興業高(gao)(gao)壓(ya)無功(gong)補償(chang)裝(zhuang)置（簡稱RSVG），采(cai)用(yong)(yong)瞬時無功(gong)功(gong)率(lv)理論的(de)(de)(de)無功(gong)檢測方式，以功(gong)率(lv)因數、網側電(dian)(dian)(dian)(dian)壓(ya)作(zuo)為(wei)控(kong)制(zhi)目標，動態跟蹤電(dian)(dian)(dian)(dian)網電(dian)(dian)(dian)(dian)能相關指標的(de)(de)(de)變化，并根據變化情況調節無功(gong)輸(shu)(shu)出，實現電(dian)(dian)(dian)(dian)網的(de)(de)(de)高(gao)(gao)電(dian)(dian)(dian)(dian)能質量運行(xing)。控(kong)制(zhi)器采(cai)用(yong)(yong)高(gao)(gao)速DSP和(he)FPGA，實現全(quan)數字(zi)化控(kong)制(zhi)，電(dian)(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)(dian)流(liu)數字(zi)閉環和(he)載波(bo)(bo)移相技(ji)術，信號采(cai)用(yong)(yong)光纖(xian)傳輸(shu)(shu)，實現了高(gao)(gao)壓(ya)隔離，提高(gao)(gao)了整(zheng)機的(de)(de)(de)穩(wen)定性和(he)可(ke)靠(kao)性。采(cai)用(yong)(yong)IGBT組成的(de)(de)(de)H橋功(gong)率(lv)模塊鏈作(zuo)為(wei)逆變主電(dian)(dian)(dian)(dian)路的(de)(de)(de)結構形式，拓撲簡單，性能可(ke)靠(kao)，并輔助以小容量儲能元件(jian)，整(zheng)機輸(shu)(shu)出電(dian)(dian)(dian)(dian)壓(ya)由(you)多(duo)個電(dian)(dian)(dian)(dian)平臺階合成階梯(ti)波(bo)(bo)，經過輸(shu)(shu)出電(dian)(dian)(dian)(dian)抗(kang)濾波(bo)(bo)后(hou)正(zheng)弦度好(hao)。RSVG由(you)于(yu)輸(shu)(shu)出電(dian)(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)(dian)平數多(duo)，輸(shu)(shu)出波(bo)(bo)形具有更好(hao)的(de)(de)(de)諧波(bo)(bo)頻譜，因此RSVG可(ke)稱為(wei)“完美無諧波(bo)(bo)變流(liu)器”。
