RSVG高壓靜止無功發生器——35kV直掛SVG（水冷戶外）

榮信(xin)興(xing)業(ye)高(gao)(gao)壓(ya)無功(gong)補償裝置（簡稱(cheng)RSVG），采(cai)用瞬(shun)時無功(gong)功(gong)率理論(lun)的(de)無功(gong)檢(jian)測方(fang)式，以(yi)功(gong)率因數、網(wang)側電(dian)(dian)壓(ya)作為控(kong)制(zhi)目標，動態(tai)跟蹤(zong)電(dian)(dian)網(wang)電(dian)(dian)能相關指標的(de)變(bian)(bian)化(hua)，并(bing)根據變(bian)(bian)化(hua)情況(kuang)調節無功(gong)輸(shu)出，實(shi)現電(dian)(dian)網(wang)的(de)高(gao)(gao)電(dian)(dian)能質量運行。控(kong)制(zhi)器采(cai)用高(gao)(gao)速(su)DSP和(he)FPGA，實(shi)現全數字化(hua)控(kong)制(zhi)，電(dian)(dian)壓(ya)電(dian)(dian)流數字閉環(huan)和(he)載波(bo)(bo)(bo)(bo)移相技術，信(xin)號采(cai)用光(guang)纖傳輸(shu)，實(shi)現了高(gao)(gao)壓(ya)隔離，提高(gao)(gao)了整機的(de)穩定性(xing)和(he)可靠性(xing)。采(cai)用IGBT組成的(de)H橋(qiao)功(gong)率模塊鏈作為逆(ni)變(bian)(bian)主電(dian)(dian)路的(de)結構形式，拓撲簡單(dan)，性(xing)能可靠，并(bing)輔助以(yi)小容量儲能元件，整機輸(shu)出電(dian)(dian)壓(ya)由(you)多(duo)個電(dian)(dian)平臺(tai)階合成階梯波(bo)(bo)(bo)(bo)，經(jing)過輸(shu)出電(dian)(dian)抗濾波(bo)(bo)(bo)(bo)后正弦度(du)好。RSVG由(you)于(yu)輸(shu)出電(dian)(dian)壓(ya)電(dian)(dian)平數多(duo)，輸(shu)出波(bo)(bo)(bo)(bo)形具有更好的(de)諧波(bo)(bo)(bo)(bo)頻譜(pu)，因此RSVG可稱(cheng)為“完(wan)美無諧波(bo)(bo)(bo)(bo)變(bian)(bian)流器”。
