水电在中国发电行业中扮演着重要角色。对电站经济运行效率进行评价，对促进水资源管理，为电网创造更大效益具有重要意义。因此，本研究的主要目的是建立一套评价指标，并探讨评价方法，对电站的经济运行进行评价。在运行图的基础上，提出了相对耗水率(RC)、相对水电利用率(RU)和相对水电利用率增长率(RI)三个评价指标。选择龙羊峡电站作为西北电网中国段最大调峰源和黄河流域最大水库，进行经济运行效率评价。结果表明，该电站经济运行不合理，RC&1、RU<；1和0。并通过对龙羊峡水库实际运行情况的分析，说明了评价结果的合理性。
Hydropower plays a major role in the Chinese electricity generation industry. It is of significant importance to perform efficiency evaluation of the economic operation in a power station, which can help promote better water resources management and create more benefits for power network. Therefore, the main goal of this study is to establish a set of evaluation indexes and investigate the evaluation method to assess the economic operation in a power station. Based on the operation chart, three evaluation indexes including the Relative Water Consumption Rate (RC), the Relative Hydropower Utilization Rate (RU), and the Relative Hydropower Utilization Increasing Rate (RI) were proposed. The Longyangxia power station, as the biggest peak regulation source in the Northwest Power Network in China and the largest reservoir in the Yellow River Basin, was selected to perform an efficiency evaluation of economic operation. The result showed that the economic operation of this power station was not reasonable withRC> 1,RU< 1 andRI< 0. And the rationality of the evaluation result was illustrated through analyzing the actual operation situation of the Longyangxia reservoir.
