RSVG高壓靜止無功發生器——35kV直掛SVG（水冷戶外）

榮信(xin)興業高(gao)壓(ya)無(wu)(wu)(wu)功(gong)(gong)補償裝置（簡稱RSVG），采(cai)用(yong)瞬時無(wu)(wu)(wu)功(gong)(gong)功(gong)(gong)率理(li)論的(de)無(wu)(wu)(wu)功(gong)(gong)檢測方式，以(yi)功(gong)(gong)率因數(shu)、網側電(dian)(dian)(dian)壓(ya)作為(wei)控(kong)(kong)制目標，動(dong)態跟蹤電(dian)(dian)(dian)網電(dian)(dian)(dian)能相關指(zhi)標的(de)變化，并根據(ju)變化情況(kuang)調節無(wu)(wu)(wu)功(gong)(gong)輸出(chu)，實現(xian)電(dian)(dian)(dian)網的(de)高(gao)電(dian)(dian)(dian)能質(zhi)量運行。控(kong)(kong)制器采(cai)用(yong)高(gao)速DSP和(he)FPGA，實現(xian)全數(shu)字化控(kong)(kong)制，電(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)流數(shu)字閉環和(he)載波(bo)(bo)(bo)移相技(ji)術，信(xin)號(hao)采(cai)用(yong)光纖傳輸，實現(xian)了(le)高(gao)壓(ya)隔(ge)離，提(ti)高(gao)了(le)整機(ji)的(de)穩定性(xing)(xing)和(he)可靠性(xing)(xing)。采(cai)用(yong)IGBT組(zu)成的(de)H橋功(gong)(gong)率模塊鏈作為(wei)逆(ni)變主電(dian)(dian)(dian)路的(de)結構(gou)形式，拓撲簡單，性(xing)(xing)能可靠，并輔助以(yi)小容量儲能元件，整機(ji)輸出(chu)電(dian)(dian)(dian)壓(ya)由多(duo)個(ge)電(dian)(dian)(dian)平臺階合(he)成階梯(ti)波(bo)(bo)(bo)，經過輸出(chu)電(dian)(dian)(dian)抗濾波(bo)(bo)(bo)后正弦度好。RSVG由于輸出(chu)電(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)平數(shu)多(duo)，輸出(chu)波(bo)(bo)(bo)形具有(you)更好的(de)諧(xie)波(bo)(bo)(bo)頻譜，因此RSVG可稱為(wei)“完美無(wu)(wu)(wu)諧(xie)波(bo)(bo)(bo)變流器”。
