三峡电站共装单机容量700 MW,水轮发电机组26台,总装机18200 MW,按“无人值班(少人值守)”原则配置,内容完整全面,基本满足电站运行要求。本文对三峡电站投产以来机组自动化元件运行过程中出现的异常情况进行了仔细分析,特别是自动化元件同电站实际运行环境的适应性分析,总结出了自动化元件换型改造经验,成功的用于三峡电站自动化元件的换型改造,为电站的稳定安全运行提供了有力保障,同时可用于主机厂在自动化元件选型参考。
The Three Gorges Power Station has a total installed capacity of 700 MW and hydro-generating units of 26 units with a total installed capacity of 18,200 MW. It is equipped with the principle of “unattended (less attended)” and has complete and comprehensive contents and basically meets the operation requirements of the power station. In this paper, the anomalies that occur during the operation of the unit automation components since the Three Gorges Power Station was put into operation are analyzed carefully, especially the adaptability analysis of the automation components with the actual operating environment of the power station, and the experience of transformation and transformation of the automation components is summarized. Retrofitting and transformation of power plant automation components provide a powerful guarantee for the stable and safe operation of power plants and are also used by OEMs for reference in the selection of automation components.
