Recently, there have been many hot and cold weather in the past, and the power supply has frequently received the 'bake' test. The reporter learned from the State Grid Hunan Electric Power Co., Ltd. that the data on the evening of July 18 showed that the maximum power load of Hunan Power Grid reached 27.71 million kW. For the second consecutive day, it exceeded the maximum load of 26.64 million kilowatts in the summer of last year, setting a new record for summer electricity consumption.
In the control center of the State Grid Changsha Power Supply Company, the reporter saw that the power load curve on the big screen climbed, generally reaching the peak every day at 12 noon and around 9 pm. Yang Jun, director of the regulation center, said that since mid-to-late May, Changsha experienced three rounds of continuous high temperature above 35 degrees Celsius, the electricity consumption of residents increased significantly, and the air conditioning load accounted for one-third of the total network load. With the local economic development, the industrial electricity consumption also increased rapidly in the first half of the year.
The State Grid Hunan Electric Power Worker is conducting a comprehensive inspection of the substation No. 1 main transformer and the 10 kV I and II section busbars.
In the face of sustained high temperature and high load, State Grid Hunan Power has strengthened the management of hidden dangers for transmission lines and substations through infrared temperature measurement, ultrasonic partial discharge detection and important cross-over detection. At the same time, 1025 emergency repair teams were organized, 7580 A repairman, 1089 repair vehicles are on call, providing 24-hour uninterrupted power supply repair service.
In order to alleviate the problem of grid overload, from October last year to this year's 'Hangfeng Duxia', the State Grid Hunan Electric Power has completed a grid investment of 1.98 billion yuan in Changsha, the provincial capital. This year, the safe power supply capacity of Changsha Power Grid reached 7.2 million kilowatts, compared with the previous one. Yearly growth of 13.4%.
It is predicted that from the end of July to the beginning of August is the peak of electricity consumption in Hunan, and the electricity load will be further 'refreshed'. Yang Jun said that the power sector will adopt scientific dispatching and orderly electricity measures, including suggesting that industrial power users have peaks. Avoid peaks, arrange production reasonably, reduce landscape lighting, use electricity by high-energy-consuming enterprises, and focus on ensuring that residents, schools, hospitals and other public institutions use electricity, and strive to achieve power cuts.
