厂用电率是发电厂重要的经济指标之一。本文以西南某水电站为例,分析了该水电站历年厂用电、综合厂用电与发电量之间的关系,为厂用电经济运行提供了数据分析。同时提出了厂用电经济运行的几项措施,对降低水电站厂用电率有着实际的指导意义。 Plant electricity rate is one of the important economic indicators of power plants. Taking a certain hydropower station in Southwest China as an example, this paper analyzes the relationship between plant electricity consumption and plant electricity consumption in the past years of the hydropower station and provides the data analysis for the economic operation of the plant electricity. At the same time, several measures for economic operation of power plant are put forward, which have practical guiding significance for reducing the plant power rate of hydropower station.
