水库调度面与水电调度研究OA
Reservoir operation surface and hydropower operation research
回顾了水库优化问题的发展,讨论了水库调度中变分方法的有效性,提出了基于单向变分的库群差分调度模型.以变分理论为基础,将水电站出力表示为水位z、来水流量q与时间t的三维调度面,利用欧拉-拉格朗日方程求解了最优水位决策路径,通过推导出力公式、偏导数及欧拉-拉格朗日方程,提出了水库优化判别指数kj,为水库调度问题提供了求解新思路.
The development of reservoir optimization problems was briefly reviewed and the effectiveness of variational methods in reservoir operation was discussed.A unidirectional variational-based reservoir group differential scheduling model was proposed,which represents hydropower station output as a three-dimensional scheduling surface of water level z,inflow q,and time t,based on variational theory.By utilizing the Euler-Lagrange equation to solve the optimal water level decision path,and through the derivation of the power output formula,partial derivatives,and the Euler-Lagrange equation,a reservoir optimization discrimination index kj was proposed,providing a novel approach for solving reservoir operation problems.
