RSVG高壓靜止無功發生器——35kV直掛SVG（水冷戶外）

榮信興業(ye)高(gao)(gao)壓(ya)無(wu)功(gong)補償裝置（簡(jian)稱(cheng)RSVG），采(cai)(cai)(cai)用(yong)(yong)瞬時無(wu)功(gong)功(gong)率理論的無(wu)功(gong)檢測方式，以功(gong)率因(yin)數、網側電(dian)(dian)壓(ya)作為(wei)(wei)控(kong)(kong)制目(mu)標，動態(tai)跟蹤電(dian)(dian)網電(dian)(dian)能相關指標的變化(hua)，并根據變化(hua)情(qing)況調節無(wu)功(gong)輸出，實現電(dian)(dian)網的高(gao)(gao)電(dian)(dian)能質(zhi)量(liang)運(yun)行。控(kong)(kong)制器(qi)采(cai)(cai)(cai)用(yong)(yong)高(gao)(gao)速DSP和(he)FPGA，實現全數字(zi)化(hua)控(kong)(kong)制，電(dian)(dian)壓(ya)電(dian)(dian)流(liu)數字(zi)閉環(huan)和(he)載波(bo)移相技術，信號采(cai)(cai)(cai)用(yong)(yong)光纖傳輸，實現了(le)高(gao)(gao)壓(ya)隔(ge)離(li)，提高(gao)(gao)了(le)整機的穩定性(xing)和(he)可(ke)靠性(xing)。采(cai)(cai)(cai)用(yong)(yong)IGBT組成的H橋功(gong)率模塊鏈作為(wei)(wei)逆(ni)變主電(dian)(dian)路的結構形(xing)式，拓撲(pu)簡(jian)單，性(xing)能可(ke)靠，并輔助以小容量(liang)儲能元件，整機輸出電(dian)(dian)壓(ya)由多(duo)個電(dian)(dian)平臺階(jie)合成階(jie)梯波(bo)，經(jing)過輸出電(dian)(dian)抗濾波(bo)后正弦度好。RSVG由于輸出電(dian)(dian)壓(ya)電(dian)(dian)平數多(duo)，輸出波(bo)形(xing)具有更好的諧(xie)波(bo)頻(pin)譜，因(yin)此RSVG可(ke)稱(cheng)為(wei)(wei)“完美無(wu)諧(xie)波(bo)變流(liu)器(qi)”。
