12月20日晚，廣(guang)東省珠海(hai)(hai)市鳳凰山突發山火，公安、消防及各鎮街救援力量(liang)迅速趕赴現場開展滅火救援工作。由(you)于著火點距離珠海(hai)(hai)電(dian)網(wang)重要供電(dian)線路(lu)較近，山火可(ke)能對珠海(hai)(hai)高新區一帶的正常供電(dian)造成影(ying)(ying)響，南方電(dian)網(wang)廣(guang)東珠海(hai)(hai)供電(dian)局迅速啟動(dong)應急預案，確保供區供電(dian)不受影(ying)(ying)響。

珠海(hai)供(gong)電(dian)(dian)局輸電(dian)(dian)管理所員(yuan)工連夜對山火(huo)走勢和發展(zhan)情況進(jin)行(xing)(xing)觀(guan)察，研判山火(huo)對高壓輸電(dian)(dian)線路(lu)運行(xing)(xing)可能造成的(de)影響，與此同(tong)時，電(dian)(dian)力調度控制中心做好(hao)電(dian)(dian)網風險評估，調整運行(xing)(xing)方式。根據研判，珠海(hai)供(gong)電(dian)(dian)局在當晚隨即調整了供(gong)電(dian)(dian)負荷，做好(hao)了線路(lu)停(ting)電(dian)(dian)的(de)各種預案，并取消珠海(hai)高新區所有計劃停(ting)電(dian)(dian)工作，增設10名變(bian)電(dian)(dian)運行(xing)(xing)專業的(de)同(tong)志到4個無人值班變(bian)電(dian)(dian)站做好(hao)停(ting)送電(dian)(dian)操作準(zhun)備(bei)。

調度大廳里，調度值班人員聚集在一起，反復商討評估電網運行風險，選擇最妥當的運行方式。

由于當(dang)晚(wan)現場能見度低、天氣干燥(zao)、北(bei)風較大(da)，火(huo)勢迅(xun)速蔓延，21日上(shang)午(wu)，蔓延的大(da)火(huo)距離珠(zhu)海(hai)供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)局最近線路僅(jin)1公里，情況(kuang)十(shi)分危急，而此時(shi)如(ru)果采取主動停電(dian)(dian)(dian)(dian)(dian)措(cuo)施，將(jiang)會造成珠(zhu)海(hai)東(dong)北(bei)部(bu)金(jin)鼎、唐家、高(gao)新片區全部(bu)停電(dian)(dian)(dian)(dian)(dian)，影響4.7萬用戶(hu)用電(dian)(dian)(dian)(dian)(dian)。珠(zhu)海(hai)供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)局經過反復評估，并在請示(shi)省公司后，決定放棄主動停電(dian)(dian)(dian)(dian)(dian)。同時(shi)，珠(zhu)海(hai)供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)局以(yi)不導致變(bian)電(dian)(dian)(dian)(dian)(dian)站失壓(ya)為底線，做好電(dian)(dian)(dian)(dian)(dian)網各種跳閘組(zu)合情況(kuang)電(dian)(dian)(dian)(dian)(dian)網轉供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)方案，盡量避免出現高(gao)等級電(dian)(dian)(dian)(dian)(dian)力安全事件(jian)，并于21日上(shang)午(wu)9時(shi)啟動大(da)面積(ji)停電(dian)(dian)(dian)(dian)(dian)事件(jian)藍色預(yu)警(jing)。

21日下午15時30分，鳳凰山火(huo)災現場靠線路側(ce)山火(huo)基本撲(pu)滅。珠(zhu)海供(gong)電(dian)局利用無(wu)人(ren)機(ji)勘察確認(ren)，對線路的威(wei)脅已解除后(hou)，供(gong)電(dian)局根據市指(zhi)揮部(bu)(bu)統一部(bu)(bu)署，解除了大(da)面積停電(dian)事件(jian)藍色預警(jing)。

據(ju)了解，珠海供(gong)電(dian)局(ju)在(zai)整(zheng)個處置過(guo)程中無人員傷亡、無設備因災損失(shi)，未對用戶(hu)造成停電(dian)影響。
