摘要
日调峰水电节煤率（单位电能节煤量）同基荷水电不同，前者不仅高于后者，而巨随日调峰历时的缩短而急剧增大，且变幅很大，越是尖峰区，节煤率越大。本文给出了水电节煤率的数学模型，计算结果证实了上述结论。这就是说，日调峰水电在一定工作容量下年利用小时数越低，其节煤率越高。
Coal-saving ratio of hydropower stations regulating daily peak load is larger than that of hydropowerstations providing base load. In the meantime, the shorter the regulating Period, the larger the ratio; the nearer to peak load the operation time, the larger the ratio. This paper presents a mathematical model ofcoal-saving ratio. Computation results justify the above conclusion. That is, under a cerium capacity, thesmaller the total number of daily regulating hours in a year, the higher the ratio.
