“迎峰度夏”对于电力企业来说,是一个非常重要的关键词。每年夏季,当电力客户在盛夏酷暑享受着现代文明——电力带来的清凉时,电力企业却接受着严峻的考验。2010年的夏季用电,又有着别样的不同。随着经济的复苏和回暖,电力负荷不断增加;极端天气带来的干旱、洪涝、飓风等自然灾害考验着电力设施和电力供应的安全;而电煤的紧缺和价格的上涨使电力企业犹如雪上加霜,水利发电因干旱带来的蓄水量不足也影响着机组的出力,加之世博保电和炎炎夏日带来的负荷增长,使今年夏季电力供需形势变得错综复杂,迎峰度夏遭受严峻考验。为确保电力安全可靠供应,国家电网公司和南方电网公司未雨绸缪、积极准备,有效调控发电负荷,达到各级电网协调发展和电力供需平衡;有效储备水利资源和电煤储量;发电企业在电煤价格高企、企业长期亏损的情况下,周密部署统筹协调,积极采购电煤,以确保电源侧电力供应。同时,加强需求侧管理,合理调配使用负荷;主动检测客户端用电设备,消除供电安全隐患;制订防洪防汛应急预案,为抗洪排涝打下坚实的基础。各项措施的实施,为世博保电和迎峰度夏用电做好了充分的准备。在夏日负荷高峰来临之际,本刊特编辑“严阵以待迎夏峰”专题,供读者参考。
“Peak summer ” for the power companies, is a very important keyword. Every summer, when electric power customers enjoy the modern civilization in the midsummer summer, the cool power brought by electric power, electric power companies are facing a severe test. The summer of 2010 electricity, there are different kind of difference. As the economic recovery and recovery, the electricity load continues to increase; natural disasters such as droughts, floods and hurricanes caused by extreme weather test the safety of power facilities and power supply; and the shortage of power coal and the rise in prices make the power companies worse off , Water conservancy and hydropower due to lack of water storage also affect the unit’s output, coupled with the World Expo power and summer heat load growth, so that this summer’s electricity supply and demand situation has become intricate, the peak summer suffered a severe test . In order to ensure the safe and reliable supply of power, State Grid Corporation and China Southern Power Grid Corporation take precautions to actively prepare and effectively control the load of power generation to achieve the coordinated development of all levels of power grids and the balance between power supply and demand; effectively reserve water conservancy resources and coal reserves; In case of long-term business losses and high losses, the Company will make careful arrangements for co-ordination and active procurement of coal to ensure the power supply on the power supply side. At the same time, DSM needs to be strengthened to rationally allocate service load. Proactive testing of customer-side electrical equipment eliminates potential safety hazards in power supply. Flood control and emergency response plans have been prepared to lay a solid foundation for flood control and drainage. The implementation of various measures for the Expo power and summer peak electricity to make a full preparation. At the dawn of the summer peak load, this issue of special edit “vigilant welcome summer peak” topic, for readers reference.
