日前，川內首(shou)家數(shu)字(zi)化(hua)變(bian)(bian)電(dian)站——110千伏南(nan)塔變(bian)(bian)電(dian)站數(shu)字(zi)化(hua)改造項目啟動，四川電(dian)力設計咨詢公(gong)司承擔了該項工程(cheng)的(de)設計任務(wu)，該工程(cheng)計劃在2008年6月份完工。
相對于常規(gui)變(bian)電(dian)(dian)(dian)站(zhan)(zhan)(zhan)，數(shu)字(zi)化(hua)(hua)變(bian)電(dian)(dian)(dian)站(zhan)(zhan)(zhan)的(de)特(te)點是(shi)(shi)電(dian)(dian)(dian)子(zi)式(shi)互感(gan)器取(qu)代(dai)常規(gui)的(de)互感(gan)器，通(tong)(tong)過(guo)光纖、通(tong)(tong)信線組成數(shu)字(zi)化(hua)(hua)網絡，以統一(yi)的(de)規(gui)約(yue)實現采用數(shu)字(zi)化(hua)(hua)控制(zhi)、保護(hu)等功能。數(shu)字(zi)化(hua)(hua)變(bian)電(dian)(dian)(dian)站(zhan)(zhan)(zhan)與常規(gui)變(bian)電(dian)(dian)(dian)站(zhan)(zhan)(zhan)比較(jiao)具備三點突出優(you)勢：一(yi)是(shi)(shi)電(dian)(dian)(dian)子(zi)式(shi)互感(gan)器的(de)使用徹底解決了系(xi)統暫態(tai)響應(ying)及電(dian)(dian)(dian)磁干(gan)擾(rao)問題，保護(hu)更加可靠、測量更加精(jing)確；二(er)是(shi)(shi)通(tong)(tong)過(guo)數(shu)字(zi)化(hua)(hua)網絡取(qu)代(dai)常規(gui)控制(zhi)電(dian)(dian)(dian)纜(lan)，更加簡潔、清晰、可靠；三是(shi)(shi)數(shu)字(zi)化(hua)(hua)變(bian)電(dian)(dian)(dian)站(zhan)(zhan)(zhan)較(jiao)常規(gui)變(bian)電(dian)(dian)(dian)站(zhan)(zhan)(zhan)在設計(ji)、施工、調試(shi)(shi)、運(yun)行(xing)各環節(jie)更加方便(bian)快捷。目前(qian)，國內部分省市已經(jing)開(kai)始(shi)進行(xing)試(shi)(shi)點建設，積累經(jing)驗，為大規(gui)模推廣(guang)奠(dian)定(ding)基礎。
據專家預見，數字化變電站是大勢所趨，是未來變電站模式的發展方向。
