With more than 1,000 ice-covered lines, CSG launched the Emergency Response to Freezing Disaster (Grade IV) and assisted 6,000 people a day to prevent icing
Guangzhou - At 12: 30, January 10, engineers from China Southern Power Grid started the Emergency Response to Freezing Disaster (Grade IV) against the current cold wave shuttering most of South China, to ensure the safety and stability of the power grid and the orderly supply of electricity.
Driven by unceasing economic growth and a massive cold wave moving south through Mongolia, CSG senior managers witnessed a rapid growth in power consumption, with the daily maximum load up by more than 30% year-on-year, close to last summer's highest load (only 0.6% lower).
Among this, the power load of the Guangdong Power Grid exceeded 100 GWh, five months earlier than the previous year. The power grids of Guangxi, Yunnan and Guizhou repeatedly hit records highs with Guangxi and Yunnan power grids reaching more than 30 GWh).
According to experts at the CSG Power Dispatching and Communication Center, the power supplies of CSG will continue to be challenged due to the combined effects of sharply declining hydropower generation capacity during dry season, tight supplies of coal and gas and heavily ice-covered electrical lines.
Affected by the current cold wave, many areas, including the Zhaotong, Yunnan Province, Shaoguan and Qingyuan, Guangdong Province, have recorded low temperatures of minus 3-9 degrees Celsius, where transmission lines were covered by ice of different thickening degrees.
Since January 5, an accumulated 2,771 ice-covered lines of 10kV and above have been found, 221 of which were 110kV and above with an ice ratio of more than 0.3. On January 8-9, the number of users being affected in Yunnan and Guizhou significantly increased.
From 17: 00 on January 8 to 17: 00 on 9, CSG suffered 1,198 ice-covered lines which were 10kV and above. As of 17: 00 on January 9, more than 180,000 users were impacted, mainly in Yunnan and Guizhou Provinces and 46% of which had been restored, with no key users being affected.
China Southern Power Grid engineers closely monitor the ice conditions and the impact on power lines through online monitoring system, human observations and drone inspection, in order to deice on time. Since January 7, CSG has been daily dispatching more than 6,000 staff to deice the electrical lines.
According to the Guangzhou Meteorological Department, the current low temperatures throughout South China is expected to continue. CSG senior managers will reduce the impact of the cold wave on power lines and users and ensure the stability of the power supplies by taking advantage of resource platforms and regulating the power supplies.
CSG has placed a great emphasis on the newly operated Kunliulong DC project to supply power for Guangdong and Guangxi, while postponing the overhaul and maintenance services which may affect the power supply.
Previously when facing the tension in power supply and record consumer and business demand since this winter, CSG senior managers introduced 15 key measures to secure the Company’s power supply in terms of energy supplies, operational arrangements, equipment management and power supply services, to ensure a reliable supply of electricity in its key five southern provinces.
On January 8, workers from the Guizhou Power Grid were deicing transmission lines with vibrating devices on a mountain top more than 1,700 meters high
