摘要
从流域梯级电站优化调度、厂内经济运行以及经济运行评价等几个方面,以构皮滩发电厂为例探讨了水电站经济运行所采取的措施。通过对影响发电耗水率、水量利用率、综合出力系数、弃水期负荷、水能利用提高率等指标的主要因素分解,确定反映水电站经济运行状况的综合指标,构建了水电站经济运行管理的评价指标体系,并对其应用情况进行了分析,以期为大型水电站的经济运行管理提供有益的参考。
Based on the case study of the Goupitan Hydropower Station, this paper studies measures to be taken for the economical operation of a hydropower station from the aspects of optimal dispatch of cascade power stations, economical operation and the operation evaluation for a particular station. Through decomposition of the main factors which affect the main indexes such as the water consumption rate for power generation, capacity factor of power water, composite output factor, loads during water abandonments and the increase rate of hydro energy utilization. The paper establishes some comprehensive indexes which can better reflect the economical operation of a hydropower station, and builds an index evaluation system. Applications of the new indexes and the evaluation system in the hydropower stations are analyzed in the hope to provide useful reference for the improvement of economical operation for large-scale hydropower stations.
