白莲河水库常规发电调度图的优化研究

Study on Optimization of Conventional Power Generation Scheduling Figure of Bailian River Reservoir

水库常规发电调度图简单直观、操作方便,但其制订的理论基础不够扎实,调度效果不理想。为了对常规发电调度图进行优化,使其更好地指导水库的实际运行,以白莲河多年调节水库为例,以发电量最大为目标建立数学模型,进行长系列径流资料的优化计算,得到确定性优化运行轨迹。优化轨迹与常规发电调度图配合组成优化空间,在此空间内对常规发电调度图进行优化。模拟结果表明,与常规发电调度图相比,优化后的常规发电调度图各项运行指标均有较大幅度的提高,优化效果较好,可指导水库实际运行。

The conventional power generation scheduling chart is simple and intuitive,as well as easy to be operated,but it is still limit in some respects.The paper chose the Bailian River Reservoir as the research object and established the mathematical model with the goal of maximizing the capacity of power generation to get the deterministic optimal trajectory by optimal calculation on the basis of the long series of runoff data.The conventional power generation scheduling figure is optimized in the space composed by the optimal trajectory and the conventional power generation scheduling figure.The simulation results show that compared with conventional power generation scheduling figure,the optimal conventional power generation scheduling figure is better and the operation indexes are significantly improved.So,the optimal conventional power generation scheduling figure can guide the reservoir actual operation.
