At the beginning of the new year, the Beijing-Tianjin-Hebei region encountered a rare blizzard, and the central and eastern regions also ushered in heavy snow and cold weather, making the problem of extreme weather challenging the security of power supply again into people's field of vision. The heavy memory of the ice and snow disaster at the beginning of 2008 has not gone away. People cannot help but ask: Has the disaster resistance capacity of my country's power system improved after two years? Can it withstand the re-test of abnormal ice and snow weather? The reporter conducted an interview on this. .
  At present, the snowstorm has not caused a destructive impact on China's power grid. The
  reporter learned from the State Grid on the 4th that this round of heavy snowfall and cooling weather has not caused a destructive impact on China's power grid, and the power grids in various places are running smoothly. Among them, there was no circuit trip accident caused by snowfall in North China, which experienced rare snowstorms since the evening of the 2nd.
  Zhou Gang, director of the Emergency Department of the Safety Supervision Department of the State Grid Corporation of China, said: "As of the 4th, there has been no circuit trip accident caused by snowfall in North China, and the operation of power grids in other regions is also stable and normal."
  The ice and snow weather in early November last year caused Hebei , Shanxi, Anhui, Shanghai and other places, some generator sets and power grid lines tripped and disconnected, resulting in power outages. Why didn't something similar happen this time? Zhou Gang said that from a weather perspective, the temperature around zero in early November could easily cause the wires to be covered with ice; It is the middle of winter now, and there is no such phenomenon. Plus electrical equipment has undergone a fall overhaul to improve operating conditions. More importantly, the power sector is better prepared and experienced for extreme weather.
  In response to this round of heavy snowfall, State Grid has launched relevant emergency plans at the end of December, and issued a blizzard warning to power grid companies in North China, Beijing, Tianjin, Hebei, Shanxi and other grid companies before the blizzard on the evening of January 2. The management department was on duty, and the power supply departments made various preparations for the blizzard disaster in accordance with the relevant plans and early warning requirements. Among them, Beijing Electric Power Company currently has more than 3,000 people on duty, and 799 emergency vehicles and 15 generator vehicles are on standby.
  Ge Xubo, chief engineer of the State Grid Energy Research Institute, further analyzed that after the ice and snow disaster in 2008, the ability of my country's power grid to resist ice disaster has been enhanced, and power companies have been more prepared for anti-icing and anti-icing work, and the response methods have become more diverse and effective.
  The ability of the power grid to resist ice and snow has enhanced the
  ice and snow disaster in 2008, which caused extensive damage to power facilities in China. After the disaster, "how to improve the resilience of the power system" was quickly put on the national agenda.
  "Draw the ice area division map, draw the power grid differentiation plan, and then improve the design standards for the new power transmission and transformation projects and carry out high-standard renovation of the existing lines." Ge Xubo described the anti-icing renovation for which he has been busy in the past two years. Work.
  State Grid has arranged 9 billion yuan of funds for key disaster-stricken provinces and cities such as Hunan, Jiangxi, Hubei, Henan, Sichuan, Chongqing, Zhejiang, and Anhui to carry out ice-resistant reconstruction for more than 1,000 transmission lines of 110 kV and above. All completed in 2010. According to data from China Southern Power Grid, the reinforcement of 186 lines in four provinces of Guangdong, Guangxi, Guizhou and Yunnan was completed in 2008, and the reinforcement of 59 lines carried out in 2009 was completed by the end of November.
