Core Viewpoint - The successful commissioning of 10 key power supply projects by State Grid Sichuan Electric Power ensures reliable electricity supply for the 12th World Games in Chengdu, significantly enhancing the energy security of the city and supporting high-quality regional economic development [1][2]. Group 1: Project Overview - The 12th World Games will take place from August 7 to 17 in Chengdu, necessitating high standards for electricity supply [1]. - State Grid Sichuan Electric Power has constructed 10 key power supply projects, including 1 project at 500 kV, 7 projects at 220 kV, and 2 projects at 110 kV, with a total new line length of 320 kilometers and an additional transformer capacity of 3.36 million kVA [1]. - These projects enhance the power grid capacity and supply quality for the eight core competition areas of the World Games, laying a solid energy foundation for the event [1]. Group 2: Construction Process - During the construction, State Grid Sichuan Electric Power utilized a collaborative mechanism between municipal and district levels, enhancing government-enterprise interaction to efficiently address challenges [2]. - Advanced construction technologies, such as drones for line laying and intelligent tension control, were introduced to improve construction efficiency and reduce safety risks [2]. - Over 2,100 power construction workers were involved in optimizing equipment and systems to ensure the power grid is in optimal condition for the event [2]. Group 3: Key Engineering Role - The Luojia-Dianjian 220 kV line project plays a crucial role by bringing clean hydropower from the Panxi region into the core area of the Chengdu southern power grid, alleviating load pressure on the 500 kV main grid [3]. - The project establishes a "dual-source" power supply system supported by two clean energy bases, significantly improving the stability and reliability of electricity supply [3]. - State Grid Sichuan Electric Power has also upgraded its intelligent power supply management platform, monitoring 35 key venues and implementing focused inspections on 104 substations and 232 distribution lines [3].
