针对使用《水电工程水利计算规范》推荐方法编制发电调度图存在的问题,提出了采用长系列时历法连续计算、统一年调节和多年调节水库编制方法、修正不合理的假定条件和计算过程、合理绘制降低出力区、协调降低出力区与保证出力区的关系等全面的改进方法,并通过实例进行了验证。结果表明,改进方法能适用于年调节和多年调节水库,可满足降低出力和保证出力的发电要求,计算结果符合设计保证率,调度图可一次性编制成功,无需再对调度图进行反复的检验和修改。
Aiming at the existing problems of using the recommended method of hydropower calculation of hydropower project to compile power generation scheduling diagram, the paper proposes a long series of calendar time calculation, unified year regulation and multi-year regulation of reservoir preparation methods to correct unreasonable assumptions and calculation process, Draw a reduction of output area, coordinate and reduce the output area and guarantee the output area of the relationship between the comprehensive improvement methods, and verified by an example. The results show that the improved method can be applied to annual regulation and multi-year regulation of reservoirs to meet the power generation requirements of reducing output and ensuring output. The calculated results are in line with the design guarantee rate. The schedule map can be successfully compiled in one go without repeated inspection of the schedule map And modify.
