RSVG高壓靜止無功發生器——35kV直掛SVG（水冷戶外）

榮信興業高壓(ya)無(wu)功(gong)補償裝置（簡稱RSVG），采(cai)(cai)用瞬時(shi)無(wu)功(gong)功(gong)率(lv)(lv)理論的無(wu)功(gong)檢測方(fang)式，以(yi)功(gong)率(lv)(lv)因(yin)數(shu)(shu)、網側電(dian)(dian)壓(ya)作為控(kong)(kong)制(zhi)目(mu)標，動(dong)態跟蹤電(dian)(dian)網電(dian)(dian)能(neng)相(xiang)關(guan)指標的變化(hua)，并根據變化(hua)情況調節無(wu)功(gong)輸(shu)出，實現電(dian)(dian)網的高電(dian)(dian)能(neng)質量運行。控(kong)(kong)制(zhi)器(qi)采(cai)(cai)用高速DSP和FPGA，實現全(quan)數(shu)(shu)字化(hua)控(kong)(kong)制(zhi)，電(dian)(dian)壓(ya)電(dian)(dian)流數(shu)(shu)字閉環和載波(bo)移相(xiang)技術，信號(hao)采(cai)(cai)用光(guang)纖傳輸(shu)，實現了高壓(ya)隔離，提高了整(zheng)機的穩定(ding)性和可(ke)靠(kao)性。采(cai)(cai)用IGBT組(zu)成的H橋(qiao)功(gong)率(lv)(lv)模塊鏈作為逆變主電(dian)(dian)路的結構形式，拓撲簡單，性能(neng)可(ke)靠(kao)，并輔助(zhu)以(yi)小容量儲(chu)能(neng)元件，整(zheng)機輸(shu)出電(dian)(dian)壓(ya)由多個(ge)電(dian)(dian)平(ping)臺(tai)階合成階梯波(bo)，經過輸(shu)出電(dian)(dian)抗濾波(bo)后正弦度好(hao)。RSVG由于輸(shu)出電(dian)(dian)壓(ya)電(dian)(dian)平(ping)數(shu)(shu)多，輸(shu)出波(bo)形具有更好(hao)的諧波(bo)頻譜，因(yin)此RSVG可(ke)稱為“完(wan)美(mei)無(wu)諧波(bo)變流器(qi)”。
