RSVG高壓靜止無功發生器——35kV直掛SVG（水冷戶外）

榮信興業高(gao)壓(ya)無(wu)功(gong)補償裝置（簡稱RSVG），采(cai)用(yong)瞬(shun)時無(wu)功(gong)功(gong)率(lv)(lv)(lv)理(li)論的無(wu)功(gong)檢(jian)測方式(shi)，以功(gong)率(lv)(lv)(lv)因數、網(wang)(wang)側電(dian)(dian)(dian)(dian)壓(ya)作(zuo)為控制(zhi)目標，動(dong)態跟蹤(zong)電(dian)(dian)(dian)(dian)網(wang)(wang)電(dian)(dian)(dian)(dian)能(neng)(neng)相(xiang)關指標的變(bian)化(hua)，并(bing)根據變(bian)化(hua)情況(kuang)調節無(wu)功(gong)輸(shu)出(chu)(chu)，實(shi)現(xian)電(dian)(dian)(dian)(dian)網(wang)(wang)的高(gao)電(dian)(dian)(dian)(dian)能(neng)(neng)質(zhi)量運(yun)行。控制(zhi)器采(cai)用(yong)高(gao)速DSP和(he)FPGA，實(shi)現(xian)全(quan)數字化(hua)控制(zhi)，電(dian)(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)(dian)流(liu)數字閉(bi)環(huan)和(he)載波移相(xiang)技術，信號采(cai)用(yong)光纖(xian)傳(chuan)輸(shu)，實(shi)現(xian)了高(gao)壓(ya)隔離，提高(gao)了整機的穩定(ding)性和(he)可(ke)靠性。采(cai)用(yong)IGBT組成(cheng)(cheng)的H橋功(gong)率(lv)(lv)(lv)模塊(kuai)鏈作(zuo)為逆變(bian)主電(dian)(dian)(dian)(dian)路的結構形(xing)式(shi)，拓(tuo)撲(pu)簡單(dan)，性能(neng)(neng)可(ke)靠，并(bing)輔助以小容量儲能(neng)(neng)元件，整機輸(shu)出(chu)(chu)電(dian)(dian)(dian)(dian)壓(ya)由(you)多(duo)個(ge)電(dian)(dian)(dian)(dian)平(ping)(ping)臺階合成(cheng)(cheng)階梯波，經過輸(shu)出(chu)(chu)電(dian)(dian)(dian)(dian)抗濾(lv)波后正(zheng)弦度好(hao)(hao)。RSVG由(you)于輸(shu)出(chu)(chu)電(dian)(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)(dian)平(ping)(ping)數多(duo)，輸(shu)出(chu)(chu)波形(xing)具有(you)更好(hao)(hao)的諧(xie)波頻譜，因此RSVG可(ke)稱為“完美無(wu)諧(xie)波變(bian)流(liu)器”。
