Xinhuanet, Shenyang, November 24. According to the State Grid Shenyang Power Supply Company, the 220 kV Wenxi Substation and 220 kV Grammar Line completed and put into operation in early November this year have good operating indicators. During the peak winter, it will provide 360000 kVA power supply capacity for the Shenshui New City area in southern Shenyang, and at the same time import more than 600000 kilowatts of new energy power into the Liaoning Power Grid.

According to the forecast of the meteorological department, the probability of a warm winter in Shenyang this year is relatively large. However, the continuous fermentation of El Nino has increased the intensity and frequency of extreme weather outbreaks, which does not rule out the possibility of short-term cold waves or extremely cold weather in winter. It is estimated that the maximum daily power supply of Shenyang power grid in winter this year is 0.141 billion kilowatt hours, an increase of 8.5 percent over the same period last year, and the maximum hourly power is 6.7 million kilowatts, an increase of 7.0 percent over the same period last year. In 2023, Shenyang power grid will meet the peak winter power supply and face new challenges.

To this end, the State Grid Shenyang Power Supply Company will accelerate the construction of power projects to meet the peak winter as one of the key tasks to ensure the power grid to meet the peak winter. The company completed and put into operation 220 kV wenxi substation on November 9 and 220 kV grammar line on November 13. Among them, 220 kV Wenxi Substation will provide stable power for Shenyang Area of China (Liaoning) Pilot Free Trade Zone to meet the power demand of large-scale new industrial projects in Shenshui New Town Area. The 220 kV Grammar Line solves the problem that 220 kV power grid in Kangping area is located at the end of Shenyang power grid for a long time, and improves the power transmission capacity of Kangping and Faku areas, providing stable power transmission channel for 220 kV Liaoneng Wind Farm in Kangping area, avoid the situation that the output of the wind farm is limited due to grid factors during the peak winter.

At the same time, the State Grid Shenyang Power Supply Company will also fully combine weather changes, industrial load trends and other big data to improve the accuracy of load forecasting. According to the winter load characteristics at any time to adjust the substation load situation, to ensure safe and reliable power supply equipment. The preparation of the peak winter operation mode analysis report, scientific guidance of winter operation mode arrangement and load distribution. Comprehensively sort out the information of heat exchange stations, coal-to-electricity customers, boiler rooms, etc., focus on strengthening the special patrol and special protection of core grid lines, Class A substations, "urban lifelines" and thermal protection equipment, and use "artificial unmanned aerial vehicles" infrared detection methods to carry out normalization and temperature measurement during heavy load periods, and timely dispose of hidden dangers found.

In addition, the company will continue to carry out hidden trouble investigation of power customers, promote the improvement of power supply for important power customers, urge important power customers who do not have their own emergency power supply to configure their own emergency power supply as required, and fully ensure the power safety of important power customers in the city. Open up the industry to expand the green channel, quickly respond to customer demands, continue to improve the efficiency of reporting and installation, to meet the new electricity demand of customers.
