East China Power: work together to ensure safety

National telegraph message: with the continuation of cold weather, East China power load continues to rise. However, due to adverse factors such as disastrous weather and power coal shortage, the power supply situation in East China is becoming increasingly severe. East China Power Co., Ltd. cooperates with the power companies in Shanghai, Jiangsu, Zhejiang, Anhui and Fujian to make concerted efforts and lean management to ensure the safe and stable operation of East China power

affected by the rare freezing weather of rain and snow, as of 8:00 on January 28, the snow cover along the middle and lower reaches of the Yangtze River generally reached 30 ~ 40 cm. The ice of East China power line greatly exceeds the design value, and the power loss is huge. From January 15 to now, the 500 kV line of East China power has tripped 43 times due to icing and snow. On January 17, the 500 kV Yihua DC fell two towers, and the tower head was seriously damaged; The Anhui Anqing section of the Genan DC line was shut down due to severe icing, and the voltage was reduced after de icing on the 26th. At the same time, the total power load is rising, the internal power generation capacity is reduced by 37 million KW, and the coal storage for power generation is further reduced. At present, the adjustable output of East China power is only 111 million KW

under the guidance and support of the State Grid Corporation of China, East China company gives full play to its regional power advantages, closely coordinates with the power companies in four provinces and one city, and carries out peak valley power replacement with central China power to obtain external power in the region as far as possible. Relevant departments work together to tap the internal potential. Adjust the surplus and shortage according to the different peak hours of each province and city; Use various measures to tap domestic potential, flexibly adjust the power receiving trend of provinces along the "Anhui east power transmission" line, arrange mobile standby of some hydropower stations, and adjust the unit maintenance plan; Start demand side management to ensure orderly power consumption. At present, demand side management involves a full load of more than 6million
