水电站安全与经济运行研究及其应用

综合考虑水电机组运行的安全性与经济性，提出了水电机组的机组综合稳定特性和机组综合稳定水平的概念，将机组运行工况分别归类于正常运行区、避免运行区和禁止运行区，在此基础上设计了模糊规避算法，构建了水电站安全与经济运行模型，并编制了具有通用性的水电站安全与经济运行应用软件。与常规自动发电控制（AGC）等负荷模型相比，安全与经济运行模型在确保水电机组安全运行的前提下，提高了水电站的综合效益，为实现水电站的安全与经济运行提供了一种可行方法。

RESEARCH AND APPLICATION OF SAFE AND ECONOMICAL OPERATION OF HYDROPOWER STATIONS

To solve the problem of safe and economical operation of hydropower stations, the integrative stability attribute of generator (ISAG) and integrative stability level of generator (ISLG) have been introduced. Based on these conceptions, a fuzzy shunning algorithm and a model for safe and economical operation of hydropower stations have been established. Compared with the conventional automatic generation control (AGC) model, which distributes load according to capacities of generators, the safe and economical operation model increases the economic benefit of hydroelectric stations observably.
