中文摘要：
本文借助热力学熵增表达式，阐述了水电能源系统电站的熵增一般表达式；根据“先蓄水后发电少弃水”的发电量最大调节规则，建立了改进的基于当前时段决策出流量的电站潜在水头、弃水最小熵增模型；最后归纳了水电能源系统的最小熵增模型及其求解算法。实例证明该模型对于水电站群的组合方式没有限制，适合求解大型的水电站群规划。
英文摘要：
The general entropy expression of the hydropower-system based on the thermodynamic entropy function is presented in this paper. Considering the maximum electricity production rule, the improved minimum model of the potential entropy production of water head and water abandonment based on the output decision-making of the station is studied in this paper. The minimum entropy production model is established to realize the maximum power generation of the hydropower energy time. The case study illustrates that system and the algorithm of the model is successfully concluded at the same the model can satisfies the requirements of the hydropower system planning.
