      “十三五(wu)”時(shi)(shi)期(qi)，東(dong)北電(dian)(dian)(dian)網(wang)(wang)首條(tiao)特高(gao)(gao)壓(ya)(ya)直(zhi)(zhi)流(liu)外送通道(dao)——魯固直(zhi)(zhi)流(liu)投運(yun)(yun)。隨著(zhu)特高(gao)(gao)壓(ya)(ya)直(zhi)(zhi)流(liu)電(dian)(dian)(dian)網(wang)(wang)的發(fa)展，東(dong)北電(dian)(dian)(dian)網(wang)(wang)穩定問(wen)題凸顯(xian)，地(di)(di)區(qu)(qu)安(an)(an)全(quan)(quan)運(yun)(yun)行風險(xian)加(jia)大。同時(shi)(shi)，由于東(dong)北地(di)(di)區(qu)(qu)新(xin)能源(yuan)發(fa)展迅速，大規模新(xin)能源(yuan)并網(wang)(wang)的匯集站短(duan)路(lu)容(rong)量偏低(di)，系(xi)(xi)統(tong)(tong)(tong)寬頻(pin)振(zhen)蕩(dang)風險(xian)加(jia)大。東(dong)北電(dian)(dian)(dian)網(wang)(wang)系(xi)(xi)統(tong)(tong)(tong)保護(hu)工(gong)程是(shi)提(ti)升防御(yu)嚴(yan)重(zhong)故障引發(fa)系(xi)(xi)統(tong)(tong)(tong)性風險(xian)能力的關鍵手(shou)段(duan)(duan)。針(zhen)對(dui)特高(gao)(gao)壓(ya)(ya)直(zhi)(zhi)流(liu)閉鎖(suo)引發(fa)的頻(pin)率(lv)安(an)(an)全(quan)(quan)風險(xian)，該(gai)(gai)工(gong)程統(tong)(tong)(tong)籌協調全(quan)(quan)網(wang)(wang)新(xin)能源(yuan)、水(shui)電(dian)(dian)(dian)、火電(dian)(dian)(dian)等資源(yuan)，在(zai)(zai)線防控(kong)(kong)(kong)風險(xian)。該(gai)(gai)工(gong)程通過(guo)就地(di)(di)實時(shi)(shi)電(dian)(dian)(dian)壓(ya)(ya)精準(zhun)感知(zhi)和(he)多點(dian)優化協調對(dui)無功資源(yuan)進行自動(dong)反(fan)時(shi)(shi)限(xian)調控(kong)(kong)(kong)，實現特高(gao)(gao)壓(ya)(ya)直(zhi)(zhi)流(liu)近(jin)區(qu)(qu)工(gong)頻(pin)電(dian)(dian)(dian)壓(ya)(ya)的秒(miao)級自動(dong)快速控(kong)(kong)(kong)制；通過(guo)“源(yuan)頭監(jian)控(kong)(kong)(kong)、路(lu)徑監(jian)測、火電(dian)(dian)(dian)控(kong)(kong)(kong)保”的寬頻(pin)振(zhen)蕩(dang)三道(dao)防線，可在(zai)(zai)振(zhen)蕩(dang)發(fa)生初期(qi)快速精準(zhun)定位(wei)并切除振(zhen)蕩(dang)源(yuan)；對(dui)穩控(kong)(kong)(kong)系(xi)(xi)統(tong)(tong)(tong)通信鏈(lian)路(lu)進行網(wang)(wang)絡安(an)(an)全(quan)(quan)布控(kong)(kong)(kong)，防止惡意攻擊和(he)非法(fa)入侵導致的誤動(dong)；為調度提(ti)供(gong)更為直(zhi)(zhi)觀的系(xi)(xi)統(tong)(tong)(tong)保護(hu)實時(shi)(shi)運(yun)(yun)行監(jian)控(kong)(kong)(kong)手(shou)段(duan)(duan)。該(gai)(gai)工(gong)程為跨區(qu)(qu)資源(yuan)優化配置和(he)大規模新(xin)能源(yuan)集中發(fa)電(dian)(dian)(dian)保駕護(hu)航，有利于在(zai)(zai)當前保供(gong)形勢下保障東(dong)北、華北地(di)(di)區(qu)(qu)電(dian)(dian)(dian)力充足供(gong)應。

      2016年以(yi)來，國網東北分部組織區域內四家(jia)省級電(dian)力(li)公司、中國電(dian)科院、南(nan)瑞集團、保護設備制造(zao)廠(chang)家(jia)等(deng)聯合開展系(xi)統(tong)保護研發(fa)和建設，持(chi)續(xu)開展電(dian)網特性分析(xi)、系(xi)統(tong)設計(ji)、策略研究、裝置(zhi)研發(fa)、實時(shi)數字仿真系(xi)統(tong)驗證、現場(chang)實施等(deng)工作，為系(xi)統(tong)保護工程順利(li)投(tou)運奠(dian)定(ding)基(ji)礎。

      自(zi)(zi)2018年7月(yue)高(gao)(gao)頻(pin)緊急(ji)控(kong)(kong)(kong)制(zhi)系(xi)統(tong)投運(yun)至今，東(dong)北電(dian)(dian)網系(xi)統(tong)保護(hu)工(gong)程(cheng)控(kong)(kong)(kong)制(zhi)電(dian)(dian)源容量達到5105萬千(qian)瓦，降低了電(dian)(dian)網頻(pin)率崩潰(kui)風險。截至2021年年底，高(gao)(gao)頻(pin)緊急(ji)控(kong)(kong)(kong)制(zhi)系(xi)統(tong)網絡安(an)(an)防裝置全部(bu)投運(yun)，為(wei)整(zheng)套系(xi)統(tong)提(ti)供(gong)了安(an)(an)全運(yun)行環境；系(xi)統(tong)保護(hu)調(diao)度端安(an)(an)全監視管理系(xi)統(tong)發揮了在線監控(kong)(kong)(kong)預警作用；扎魯(lu)特(te)特(te)高(gao)(gao)壓(ya)換(huan)流站(zhan)近區自(zi)(zi)動電(dian)(dian)壓(ya)控(kong)(kong)(kong)制(zhi)系(xi)統(tong)子站(zhan)達到6個，提(ti)升(sheng)了區域電(dian)(dian)壓(ya)穩定水平；東(dong)北電(dian)(dian)網寬(kuan)頻(pin)振蕩監測(ce)與監控(kong)(kong)(kong)系(xi)統(tong)站(zhan)點達到74個，可(ke)及時將(jiang)寬(kuan)頻(pin)振蕩風險控(kong)(kong)(kong)制(zhi)在最小范圍內。國網東(dong)北分(fen)部(bu)后續將(jiang)繼續結合系(xi)統(tong)變化(hua)，滾動調(diao)整(zheng)優化(hua)系(xi)統(tong)保護(hu)布(bu)點及控(kong)(kong)(kong)制(zhi)策略。
