9月20日，秋雨绵绵的陇南大地，110千伏同谷变电站内却是一派热火朝天的施工景象。国网陇南供电公司变电运检中心各专业班组正 在冒雨进行1号主变压器附件的安装调试工作，这场与时间赛跑的供电保障攻坚战已进入关键节点冲刺阶段。 图为9月20日，国网陇南供电公司变电检修班检修人员王旭东正在110千伏同谷变工作现场维护变压器热油循环装置。 据悉，110千伏同谷变电站于2003年建成投运，肩负着陇南市成县片区的核心电能中转、区域电网稳定供电的重任。近年来，周边地区 农业、工业发展迅猛，加之两台运行22年的主变压器内部老化、负荷承载能力不足等问题加剧，亟待升级改造。 为进一步优化电网电力配置、夯实电网运行稳定性、满足用户侧多样化需求，该公司迅速制定并积极推进检修计划，对1、2号主变压 器及各电压等级设备进行全面升级改造。本次技改还将会把原有户外110千伏敞开式电气设备全面更换为HGIS组合式电气设备，极大地减 少沙尘、潮湿、盐雾等环境因素对电气设备的侵蚀，从根本上消除多项安全隐患。 结合本次主变更换工作风险等级高、作业难点多的特点，该中心严格落实"三个提升"要求，在前期准备阶段，对涉及停电围栏布置、 工器具及特种车辆到场到 ...

Core Viewpoint - The Belvis photovoltaic power station project, developed by China Three Gorges Corporation and constructed by China Railway Construction International Investment Co., showcases a successful model of green cooperation between China and Spain, emphasizing ecological protection and advanced technology in renewable energy [2][4]. Group 1: Project Overview - The Belvis photovoltaic power station covers an area of approximately 1.81 million square meters, with a total installed capacity of 104 megawatts and an annual power generation of about 200 million kilowatt-hours, officially commencing full-capacity commercial operation in March this year [2]. - The project integrates ecological considerations from the selection of the site, avoiding sensitive ecological areas and implementing wildlife corridors, while construction methods were chosen to minimize disturbance to the local environment [2][3]. Group 2: Technological Innovations - The power station employs advanced technology, including a high-efficiency drone inspection system that utilizes high-definition aerial photography and thermal imaging to quickly identify faults in photovoltaic components, significantly improving response speed and accuracy in maintenance [3]. - Plans for further automation and intelligent operation equipment, such as automatic cleaning devices and mowing machines, are in place to enhance operational efficiency during the station's operational period [3]. Group 3: Economic and Industrial Impact - The project utilizes core facilities such as photovoltaic modules and inverters that are manufactured in China, highlighting China's global competitiveness in the renewable energy manufacturing sector and positively influencing local equipment standards and industrial chain development in Spain [4]. - The Spanish government aims for renewable energy to account for 81% of its electricity structure by the end of 2030, accelerating the layout of new energy projects, while Chinese companies bring advantages in technology integration and industrial chain consolidation to support Spain's energy transition [4].
