石桥水电站增效扩容改造探讨

Discussion on efficiency increase and capacity expansion renovation in Shiqiao Hydropower Station

本文以辽宁省凤城石桥水电站为实例,分析了该水电站运行现状及存在的主要问题,并针对性地提出了石桥水电站增效扩容改造工程施工设计方案。石桥水电站增效扩容改造后,能够显著提升水轮机、变压器等发电效率,进一步提升装机容量与年平均发电量,增效扩容空间十分广阔。

In the paper,Liaoning Fengcheng Shiqiao Hydropower Station is adopted as an example for analyzing present operation condition and main problems in the hydropower station. The construction design plan of efficiency increase and capacity expansion renovation project in Shiqiao Hydropower Station is proposed in a targeted mode. After efficiency increase and capacity expansion renovation is implemented in Shiqiao Hydropower Station,the power generation efficiency of water turbine, transformer, etc. can be prominently improved. Installed capacity and average annual electricity production can be further improved. There is wide space for the development of efficiency increase and capacity expansion.
