摘要
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 problem of drawing the graph of reservoir operation that used the recommended method in Specification on Water Conservancy Computation of Hydroelectric Projects, the article presents a comprehensive improve- ment method, which adopts long series continuous calculating, unified year and multi year regulation reservoir. The im- proved method fixed unreasonable assumptions and computing process, drew reasonably reduced output area, and coordi- nated the relationship between reduced output area and guaranteed output area. The improved method was validated by examples. The results indicate that the improved method is appropriate for year regulation reservoirs and multi year regu- lation reservoirs, and it can satisfy the requirement of the lower output and the firm output power. The calculation results comply with the design reliability, the graph of reservoir operation can be one-time success, and doesn＇t need to repeated- ly examining and modifying.
