于家河水库水电站增容改造经济效益分析研究

Economic Benefit Analysis on Unit Capacity Enlargement of Yujia River Reservoir Hydropower Station

针对于家河水库除险加固后水库特性指标及引水流量发生变化,且存在机组设备不匹配、陈旧老化、长期低水位运行等问题。通过对水库多年平均来水量及水电站出力计算,采取水电站增容扩效措施,合理选择水轮机及装机容量,并对改造后的水电站进行经济效益分析。研究证明,机组增容方案是合理的、可行的,对以后的相似工程推广应用具有理论及实践意义。

Due to the characteristic index and water flow of Yujia River Reservoir Hydropower Station changes after reinforcement, and exist the problem about unit equipment does not match, obsoles- cence, long - term operating on low water level. By calculating annual average inflow and hydropower output, take effective measures of unit capacity enlargement, select the reasonable hydraulic turbine and installed capacity, then make a economic benefit analysis on unit capacity enlargement hydropower station. It shows that, the Program is Reasonable and practicable. It has theoretical and practical significance for the following similar engineering application.
