国网庆阳供电公司：甘肃庆阳怀安110千伏变电站35千伏配套送出工程成功投运

Core Viewpoint - The successful operation of the 110 kV substation and its associated 35 kV transmission project in Huai'an, Gansu, significantly alleviates the power supply bottleneck in Huachi County, providing a robust foundation for local industrial development and improving living standards [1][5]. Background of the Project - The two existing 35 kV substations in Huachi County faced increasing power supply and demand conflicts due to the growth of the petroleum industry and rising residential and commercial loads. By 2021, the load rates of these substations reached 46.32% and 69.75%, nearing their capacity limits [3]. - The original power supply lines connecting these substations had been in operation for over 37 years, leading to aging issues and frequent faults. Additionally, the lines had a large supply radius and low terminal voltage, which restricted local economic and social development [3]. Project Implementation - The company coordinated multiple specialties to ensure the project's smooth operation, with each department focusing on specific tasks such as overall scheduling, equipment performance testing, risk prevention, and user communication [4]. - The new 35 kV lines directly supply the two substations, significantly enhancing regional power transmission capacity and alleviating load pressure while resolving issues related to the old lines [4]. Post-Operation Outcomes - The power supply structure in Huachi County has been significantly optimized, with enhanced supply capacity that meets current demands and accommodates future load growth, supporting local industrial upgrades and investment attraction [5]. - The reliability of the power supply has improved, meeting N-1 safety requirements, ensuring uninterrupted power even in the event of a single line or equipment failure [6]. - Voltage quality at the user end has improved, enhancing stability for both residential and industrial electricity use, thereby increasing public satisfaction and business confidence [6]. Future Focus - The company aims to continue addressing local economic and social electricity demands, optimizing regional grid structures, and enhancing power supply service levels to support rural revitalization and industrial development [6].
