摘　　要：本文采用分解离散模型来设计多区域互联电力系统负荷频率分散控制系统。将联络线交换功率考虑为可测扰动,成功地实现了多区域的分解。以广义最小方差控制原理为基础导出了扩展控制规律。采用离散模型,有效地减少了需测变量数,简化了控制装置。文中给出了实例及仿真结果。Decomposed discrete models, can be used to design load frequency' controllers in multi-area power systems.Considering the exchanging real power in tie-lines as a measurable disturbance, the multi-area power system is decomposed into several subsystems.On the basis of generalized minimum variance control principles, an expanded control rule is induced. Using discrete models, the proposed method greatly decreases the number of varialles in be measured and simplifies the control system. The method is illustrated with a two-area power system example and its simulation Jesuits.
