水电站经济调度考核计算研究

Examining computation study of economic opeation of hydropower station

水电站经济调度是电力系统调度的重要环节。合理量化经济调度产生的效益,是水库调度面临的一个重要生产实际问题。本文通过分析衡量水电站经济调度效果的标准,提出了考核指标,即相对发电耗水率和相对水能利用率,并给出了计算公式。在此基础上,针对龙羊峡电站的实际情况,建立了龙羊峡水电站经济调度考核模型,并对2001年的实际调度运行进行了考核。

Economic operation of hydropower station is very important for electric power system. Rational quantification of economic operation benefit is a practical problem confronted with reservoirs. According to analyzing the criterion of weighing the economic operation results, the examining indexes are put forward, i.e. relative water consuming rate to generate electricity and relative water power utilization rate the computation formulas ae also given. The economic operation model of Long Yangxia power station is established and the actual operation results in 2001 are examined.
