《水库调度设计规范》中时历法编制发电调度图的改进研究

应用《水库调度设计规范》编制发电调度图,经过多次的检验和修改后仍有不合理之处,针对这一问题,提出了相应的改进措施,改进方法消除了规范推荐方法中不合理的问题,改用时历法长系列连续计算,统一年和多年调节水库的计算方法,准确计算降低出力线,使降低出力区和保证出力区不重叠,提高了发电调度线的准确性。经过实际工程应用,结果表明用改进方法能提高发电调度图的合理性,可以准确符合发电降低出力和发电保证出力的设计要求,调度结果达到发电设计保证率,发电调度图可一次性编制成功,不需要再对调度图进行检验和修改。

Improvement on power generation scheduling charts of chronological series method in Design for Operation of Reservoirs

A scheduling chart of power generation, if designed by the specifications Design for Operation of Reservoir, usually has unreasonable points that cannot be removed even by repeated testing and modification. This article presents an improvement method and measures for eliminating such points and modifying the method recommended in the specifications. This new method adopts successive calculation of long series and unifies the calculations of one-year regulation and multi-year regulation of a reservoir. It can calculate the lower power output curve accurately and avoid the overlap between low output area and guarantee output area, improving the accuracy of power generation scheduling curves. Application to actual projects indicates that the method improves power generation scheduling chart in meeting different requirements of low output and firm output. The chart can be completed in one-time success with no need for repeated testing and modification and meet the reliability requirement of power design.
