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)無功(gong)(gong)補償(chang)裝(zhuang)置(zhi)（簡稱(cheng)RSVG），采用(yong)瞬時無功(gong)(gong)功(gong)(gong)率理論的無功(gong)(gong)檢測方式(shi)，以(yi)功(gong)(gong)率因(yin)數、網(wang)側電(dian)(dian)壓(ya)(ya)作為控制(zhi)目標，動態跟(gen)蹤電(dian)(dian)網(wang)電(dian)(dian)能相關指(zhi)標的變化，并(bing)根據變化情(qing)況調節無功(gong)(gong)輸(shu)出(chu)(chu)，實現(xian)電(dian)(dian)網(wang)的高(gao)電(dian)(dian)能質量運行(xing)。控制(zhi)器(qi)采用(yong)高(gao)速DSP和(he)FPGA，實現(xian)全數字化控制(zhi)，電(dian)(dian)壓(ya)(ya)電(dian)(dian)流數字閉(bi)環和(he)載(zai)波(bo)(bo)移相技術，信號采用(yong)光(guang)纖(xian)傳(chuan)輸(shu)，實現(xian)了(le)高(gao)壓(ya)(ya)隔離，提高(gao)了(le)整機(ji)的穩定性(xing)(xing)和(he)可靠性(xing)(xing)。采用(yong)IGBT組成的H橋功(gong)(gong)率模塊(kuai)鏈作為逆(ni)變主電(dian)(dian)路(lu)的結構形式(shi)，拓(tuo)撲簡單，性(xing)(xing)能可靠，并(bing)輔助以(yi)小容量儲能元件，整機(ji)輸(shu)出(chu)(chu)電(dian)(dian)壓(ya)(ya)由(you)多個電(dian)(dian)平臺(tai)階(jie)合(he)成階(jie)梯(ti)波(bo)(bo)，經過(guo)輸(shu)出(chu)(chu)電(dian)(dian)抗濾(lv)波(bo)(bo)后正弦度(du)好。RSVG由(you)于(yu)輸(shu)出(chu)(chu)電(dian)(dian)壓(ya)(ya)電(dian)(dian)平數多，輸(shu)出(chu)(chu)波(bo)(bo)形具有(you)更(geng)好的諧(xie)波(bo)(bo)頻譜，因(yin)此RSVG可稱(cheng)為“完美無諧(xie)波(bo)(bo)變流器(qi)”。
