市场环境下水电站厂内经济运行问题研究

日前市场上，不论水电公司是采取单机组形式竞价，还是将全部电站机组合并成1台模拟机组竞价，厂内机组负荷分配均是电站经济运行的重要组成部分。文中探讨了市场环境下如何将给定的全厂日发电计划合理地分配到各台机组的问题，建立了以各时段全厂发电流量最小为目标函数的数学模型。通过实例分析，验证了所给模型的合理性和有效性。

STUDY ON IN-PLANT ECONOMIC OPERATION OF HYDROPOWER STATIONS UNDER MARKET ENVIRONMENT

On the day-ahead market, the load distribution of in-plant units is an important part of hydropower station economic operation, without reference to what kind of bidding forms taken by the hydropower company, single unit or all units as a simulative one. This paper discusses the rational distribution of the given daily generation schedule to each unit under the market environment, and formulates a mathematic model whose objective function is the minimum of generating discharge of the whole plants in every period of time. The rationality and effectiveness of the model are verified by a sample analysis.
