抽水蓄能电站调峰填谷节煤计算及评价

仅以抽水蓄能电站抽水耗煤指标作为其调峰填谷的能量转换特征指标是不全面和不完整的，因为在调峰填谷中，除以发电煤经形式表征的抽水耗煤指标外，还有填谷节煤和率和调峰填谷中，

COMPUTATION AND EVALUATION ON COAL SAVING OF PEAK CLIPPING AND VALLEY FILLING OF PUMPED STORAGE PLANT

It is not overall or complete that taking the index of coal consumption for pumping water as only characteristic index of energy conversion during peak clipping and valley filling. In addition to the coal consumption index for pumping water, the coal saving indexes for valley filling and peak clipping should be considered. This paper provides the computing model for these two indexes. The computing results show that the sum of these two coal saving rate is always bigger than unit coal consumption. In comparison with other computation methods, this one has same computing results, and is simpler and clearer.
