RSVG高壓靜止無功發生器——35kV直掛SVG（水冷戶外）

榮信興業高壓無(wu)功(gong)補償裝置（簡稱(cheng)(cheng)RSVG），采(cai)用(yong)瞬時無(wu)功(gong)功(gong)率(lv)理(li)論的(de)無(wu)功(gong)檢測方(fang)式，以功(gong)率(lv)因數、網(wang)側電(dian)(dian)(dian)壓作為控制(zhi)(zhi)目標(biao)，動態(tai)跟蹤(zong)電(dian)(dian)(dian)網(wang)電(dian)(dian)(dian)能(neng)(neng)相關指標(biao)的(de)變(bian)化，并(bing)根據變(bian)化情況調節(jie)無(wu)功(gong)輸出(chu)，實現電(dian)(dian)(dian)網(wang)的(de)高電(dian)(dian)(dian)能(neng)(neng)質(zhi)量運(yun)行。控制(zhi)(zhi)器(qi)采(cai)用(yong)高速DSP和(he)FPGA，實現全數字化控制(zhi)(zhi)，電(dian)(dian)(dian)壓電(dian)(dian)(dian)流數字閉環和(he)載波(bo)(bo)移相技術，信號采(cai)用(yong)光纖傳(chuan)輸，實現了(le)高壓隔離(li)，提高了(le)整機的(de)穩定性(xing)(xing)和(he)可(ke)靠性(xing)(xing)。采(cai)用(yong)IGBT組成的(de)H橋功(gong)率(lv)模(mo)塊(kuai)鏈作為逆變(bian)主(zhu)電(dian)(dian)(dian)路的(de)結構形式，拓撲簡單(dan)，性(xing)(xing)能(neng)(neng)可(ke)靠，并(bing)輔助以小容量儲能(neng)(neng)元件，整機輸出(chu)電(dian)(dian)(dian)壓由多(duo)個(ge)電(dian)(dian)(dian)平臺階合成階梯波(bo)(bo)，經過輸出(chu)電(dian)(dian)(dian)抗濾波(bo)(bo)后正弦度(du)好(hao)。RSVG由于輸出(chu)電(dian)(dian)(dian)壓電(dian)(dian)(dian)平數多(duo)，輸出(chu)波(bo)(bo)形具有更好(hao)的(de)諧波(bo)(bo)頻譜(pu)，因此RSVG可(ke)稱(cheng)(cheng)為“完美(mei)無(wu)諧波(bo)(bo)變(bian)流器(qi)”。
