RSVG高壓靜止無功發生器——35kV直掛SVG（水冷戶外）

榮信興(xing)業高壓(ya)(ya)無(wu)(wu)功補償裝置(zhi)（簡稱(cheng)(cheng)RSVG），采用(yong)(yong)瞬時(shi)無(wu)(wu)功功率理論的(de)無(wu)(wu)功檢測方式，以功率因數、網側電(dian)(dian)(dian)壓(ya)(ya)作為(wei)控制(zhi)(zhi)目標(biao)，動(dong)態跟蹤(zong)電(dian)(dian)(dian)網電(dian)(dian)(dian)能(neng)(neng)相關指標(biao)的(de)變(bian)化(hua)，并(bing)根(gen)據(ju)變(bian)化(hua)情況(kuang)調節無(wu)(wu)功輸出，實(shi)現電(dian)(dian)(dian)網的(de)高電(dian)(dian)(dian)能(neng)(neng)質量(liang)運行。控制(zhi)(zhi)器采用(yong)(yong)高速DSP和FPGA，實(shi)現全數字化(hua)控制(zhi)(zhi)，電(dian)(dian)(dian)壓(ya)(ya)電(dian)(dian)(dian)流數字閉環和載波(bo)移相技術，信號采用(yong)(yong)光(guang)纖傳輸，實(shi)現了高壓(ya)(ya)隔離，提高了整機(ji)的(de)穩定性(xing)和可靠(kao)(kao)性(xing)。采用(yong)(yong)IGBT組成的(de)H橋功率模塊鏈作為(wei)逆變(bian)主(zhu)電(dian)(dian)(dian)路的(de)結構形式，拓撲(pu)簡單(dan)，性(xing)能(neng)(neng)可靠(kao)(kao)，并(bing)輔助以小容(rong)量(liang)儲能(neng)(neng)元件，整機(ji)輸出電(dian)(dian)(dian)壓(ya)(ya)由(you)多(duo)個電(dian)(dian)(dian)平臺階合(he)成階梯波(bo)，經過輸出電(dian)(dian)(dian)抗濾(lv)波(bo)后正弦(xian)度好。RSVG由(you)于輸出電(dian)(dian)(dian)壓(ya)(ya)電(dian)(dian)(dian)平數多(duo)，輸出波(bo)形具有更好的(de)諧波(bo)頻譜，因此RSVG可稱(cheng)(cheng)為(wei)“完美(mei)無(wu)(wu)諧波(bo)變(bian)流器”。
