发布时间：2018-11-20 16:28
【摘要】：厂内经济运行是提高水电站水能效率的关键,但复杂水力联系和约束条件是制约水电站负荷优化分配数学模型求解的难点。针对这一问题,以复杂引水系统的漳河水库水电站群为例,通过引水系统水力联系与动力指标关系分析,以分流结点为依据将系统分解为不同层次的子系统,建立了复杂引水系统水电站负荷优化分配数学模型;以相同机组段水头(或机组流量)为依据,将子系统内并(或串)联机组段聚合成"等效机组",提出了分层次递阶结构化的模型求解方法。该原理和方法不仅具有简洁清晰的特点,而且具有灵活性、实用性及通用性的优点,对于并行计算等现代技术解决大规模水电站群系统短期优化问题具有广阔的应用前景。实例应用验证了方法的有效性、稳定性和适应性。
[Abstract]:The economic operation in the plant is the key to improve the hydraulic efficiency of hydropower stations, but complex hydraulic connections and constraints are the difficulties to solve the mathematical model of optimal load distribution of hydropower stations. In order to solve this problem, taking Zhanghe reservoir hydropower station group of complex diversion system as an example, by analyzing the relationship between hydraulic connection and dynamic index of diversion system, the system is decomposed into subsystems at different levels based on the distributary node. A mathematical model for optimal load distribution of hydropower stations in complex diversion system is established. Based on the water head (or unit flow) of the same unit section, the unit section in the sub-system and (or series) is aggregated into "equivalent unit", and a hierarchical and structured model solution method is proposed. The principle and method are not only simple and clear, but also have the advantages of flexibility, practicability and versatility. It has a broad application prospect for solving short-term optimization problems of large-scale hydropower group systems by modern techniques such as parallel computing. The effectiveness, stability and adaptability of the method are verified by an example.
