【摘要】：廠內經濟運行是提高水電站水能效率的關鍵,但復雜水力聯(lián)系和約束條件是制約水電站負荷優(yōu)化分配數學模型求解的難點。針對這一問題,以復雜引水系統(tǒng)的漳河水庫水電站群為例,通過引水系統(tǒng)水力聯(lián)系與動力指標關系分析,以分流結點為依據將系統(tǒng)分解為不同層次的子系統(tǒng),建立了復雜引水系統(tǒng)水電站負荷優(yōu)化分配數學模型;以相同機組段水頭(或機組流量)為依據,將子系統(tǒng)內并(或串)聯(lián)機組段聚合成"等效機組",提出了分層次遞階結構化的模型求解方法。該原理和方法不僅具有簡潔清晰的特點,而且具有靈活性、實用性及通用性的優(yōu)點,對于并行計算等現代技術解決大規(guī)模水電站群系統(tǒng)短期優(yōu)化問題具有廣闊的應用前景。實例應用驗證了方法的有效性、穩(wěn)定性和適應性。
[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.
