北京首座全户内500千伏输变电工程开工建设

Core Viewpoint - The construction of Beijing's first fully indoor 500 kV substation in Fengtai District is expected to significantly enhance the resilience and power supply capacity of the southern Beijing power grid, supporting the city's economic development and high-tech industries [1][2]. Group 1: Project Details - The new 500 kV substation will include two 1200 MVA transformers, an 8.7 km tunnel, and approximately 35.25 km of newly laid cable, adding a total capacity of 2400 MVA, which is equivalent to half of the existing 110 kV substation capacity in Fengtai District [1]. - The project is scheduled to be operational during the "14th Five-Year Plan" period [1]. Group 2: Strategic Importance - The 500 kV project will serve as a crucial power hub for key areas such as the capital's core zone and the Lize Financial Business District, providing reliable power support for high-tech industries like China Data Street and Lize Terminal [1]. - The project aligns with Beijing's "14th Five-Year Plan" to facilitate the cross-province transmission and efficient consumption of green electricity, enabling the direct delivery of clean energy from Zhangjiakou's wind and solar sources to Beijing's load centers [2]. Group 3: Technological Advancements - The construction will utilize mechanized construction and robotic technologies, implementing 77 standardized mechanized operations and introducing 10 new types of machinery to enhance on-site construction efficiency [2]. - The project will also catalyze the simultaneous advancement of other 500 kV substation projects in areas like Huairou Science City and CBD, contributing to the establishment of a 500 kV three-dimensional cross-ring network [2].
