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)(gong)補償裝置（簡(jian)稱RSVG），采用瞬(shun)時無(wu)功(gong)(gong)功(gong)(gong)率理論的(de)無(wu)功(gong)(gong)檢測方式，以(yi)功(gong)(gong)率因(yin)數(shu)(shu)、網側電(dian)(dian)(dian)壓(ya)作為(wei)控(kong)制目(mu)標，動(dong)態(tai)跟蹤電(dian)(dian)(dian)網電(dian)(dian)(dian)能相(xiang)關指標的(de)變化，并根(gen)據變化情況調節無(wu)功(gong)(gong)輸(shu)(shu)(shu)出，實現電(dian)(dian)(dian)網的(de)高(gao)電(dian)(dian)(dian)能質(zhi)量運行。控(kong)制器采用高(gao)速(su)DSP和FPGA，實現全數(shu)(shu)字化控(kong)制，電(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)流(liu)數(shu)(shu)字閉環和載波移相(xiang)技(ji)術，信號采用光纖傳(chuan)輸(shu)(shu)(shu)，實現了高(gao)壓(ya)隔離，提(ti)高(gao)了整機的(de)穩定性(xing)和可(ke)靠(kao)性(xing)。采用IGBT組成的(de)H橋功(gong)(gong)率模塊(kuai)鏈作為(wei)逆變主電(dian)(dian)(dian)路的(de)結構形(xing)式，拓撲簡(jian)單(dan)，性(xing)能可(ke)靠(kao)，并輔助以(yi)小容量儲能元(yuan)件，整機輸(shu)(shu)(shu)出電(dian)(dian)(dian)壓(ya)由多個電(dian)(dian)(dian)平臺階(jie)合成階(jie)梯(ti)波，經過輸(shu)(shu)(shu)出電(dian)(dian)(dian)抗濾(lv)波后正弦度好(hao)。RSVG由于輸(shu)(shu)(shu)出電(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)平數(shu)(shu)多，輸(shu)(shu)(shu)出波形(xing)具(ju)有更好(hao)的(de)諧波頻(pin)譜，因(yin)此RSVG可(ke)稱為(wei)“完美無(wu)諧波變流(liu)器”。
