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)(gong)(gong)補償裝(zhuang)置（簡(jian)稱RSVG），采(cai)用(yong)瞬時無(wu)功(gong)(gong)(gong)功(gong)(gong)(gong)率理論的(de)(de)(de)無(wu)功(gong)(gong)(gong)檢測方式，以功(gong)(gong)(gong)率因數(shu)(shu)、網(wang)側電(dian)(dian)壓(ya)作(zuo)為(wei)控(kong)制目標，動態(tai)跟(gen)蹤電(dian)(dian)網(wang)電(dian)(dian)能(neng)相關指標的(de)(de)(de)變化(hua)，并根據變化(hua)情(qing)況調節無(wu)功(gong)(gong)(gong)輸(shu)(shu)出，實現電(dian)(dian)網(wang)的(de)(de)(de)高電(dian)(dian)能(neng)質量運行。控(kong)制器采(cai)用(yong)高速DSP和FPGA，實現全數(shu)(shu)字化(hua)控(kong)制，電(dian)(dian)壓(ya)電(dian)(dian)流數(shu)(shu)字閉環和載波(bo)移相技術，信號采(cai)用(yong)光纖(xian)傳輸(shu)(shu)，實現了(le)(le)高壓(ya)隔(ge)離，提(ti)高了(le)(le)整機的(de)(de)(de)穩(wen)定性和可靠(kao)性。采(cai)用(yong)IGBT組成的(de)(de)(de)H橋功(gong)(gong)(gong)率模塊鏈(lian)作(zuo)為(wei)逆變主電(dian)(dian)路的(de)(de)(de)結構形式，拓撲簡(jian)單，性能(neng)可靠(kao)，并輔助以小容量儲能(neng)元件，整機輸(shu)(shu)出電(dian)(dian)壓(ya)由多個電(dian)(dian)平臺階(jie)合成階(jie)梯波(bo)，經過輸(shu)(shu)出電(dian)(dian)抗濾波(bo)后正弦度好。RSVG由于輸(shu)(shu)出電(dian)(dian)壓(ya)電(dian)(dian)平數(shu)(shu)多，輸(shu)(shu)出波(bo)形具有更(geng)好的(de)(de)(de)諧(xie)波(bo)頻譜，因此RSVG可稱為(wei)“完美(mei)無(wu)諧(xie)波(bo)變流器”。
