At 5:00 a.m. on August 3, in order to ensure safe power supply, the dispatching and control sub-center of the State Grid Bazhong Bazhou Power Supply Company transferred the power supply to the 10 kV niche line load.
As temperatures rise, the load imbalance of the grid becomes more and more apparent. Because of the uneven distribution of electricity load, some transformers are overloaded or even overloaded. At the same time, some transformers are still in a light-load state. In order to avoid power outage accidents caused by heavy transformers and overloads, the State Grid Bazhong Bazhou Power Supply transferred part of the line load of heavy and overloaded transformers to light-load transformers for power supply by optimizing the operation mode.
It is reported that the State Grid Bazhong Bazhou Power Supply Company has successively adjusted the operation mode to 6 110 kV substations and 9 35 kV substations, involving 2 35 kV lines and 9 10 kV lines, with a total adjustment load of 35,200 kilowatts.
Equipment inspection eliminates hidden dangers
"110 kV lookout line, the line temperature is normal, and there is no overheating phenomenon such as equipment cable clips."
On August 4, The State Grid Bazhong Bazhou Power Supply Company Transmission And Transportation Inspection Ban Zhu Wenwen and others carried out special inspection work on the 110 kV Wangda Line, a heavy-duty early warning line in the jurisdiction.
In order to further ensure that the lines can safely supply power and ensure a smooth summer, since July this year, the company's substation transportation inspection class, transmission transportation inspection class, distribution transportation inspection class and each power supply station must do one more work every day - substation and line inspection and inspection.
By strengthening special inspections and regular inspections of various substations and various types of substation equipment, switch places, transmission and distribution lines, live testing of important equipment is carried out so that all kinds of safety hazards in power supply equipment can be found in a timely manner, so that the shortage can be eliminated in time to ensure safe power supply.
According to Hu Xiao, the company's transmission transportation inspection class, since the beginning of summer, the transmission transportation inspection class has carried out inspection and inspection of more than 10 110 kV and 20 35 kV lines according to the company's peak summer work plan and early warning information issued by the regulation sub-center, with a total inspection line length of more than 800 kilometers, and found and eliminated 5 hidden dangers.
