四川电网两项500千伏工程春节前顺利投运

Core Viewpoint - The successful operation of two key 500 kV projects in Sichuan, namely the Daozhu—Xinduqiao and Guangyuan Thermal Power, enhances the reliability of the power supply and optimizes the main grid structure, supporting clean energy consumption and regional development [1][5]. Group 1: Project Details - The Daozhu—Xinduqiao 500 kV project spans approximately 115.8 kilometers, featuring 248 new towers, and aims to improve the local grid structure while stabilizing the integration of 1.5 million kW of photovoltaic power in the Daozhu area [3]. - The Guangyuan Thermal Power 500 kV project covers a length of 35.2 kilometers with 48 new towers, designed to meet the growing load demand in Northeast Sichuan and enhance the energy supply structure [3]. Group 2: Construction and Safety Measures - The construction team implemented a proactive safety system, utilizing a dual prevention model of "desktop simulation + on-site practice" to identify risks and ensure high standards in project execution [3]. - The team leveraged experience from complex terrain construction to enhance safety and quality control throughout the project lifecycle, ensuring timely completion [3]. Group 3: Future Outlook - The recent commissioning of these projects is part of Sichuan's commitment to public welfare, ensuring reliable power supply during the festive season [5]. - Future projects, such as the Aba—Chengdu East 1000 kV UHV project, are expected to further strengthen the main grid and improve clean energy consumption capabilities [5].
