摘要
广域电力系统稳定性分析与控制中一个不容忽视的问题就是广域信号的传输时延。文章提出了一种基于矩阵测度理论的分析方法。该方法从广义的角度给出了应用广域控制策略的含多时延的闭环电力系统模型;针对该模型,应用矩阵测度的现有理论给出了保证系统闭环稳定的充分条件,并能求出系统最大允许时延。文章以时域仿真结果说明了该方法的有效性。
Time delay of remote signal is an unavoidable matter for study of the wide area power system.In this paper,a new approach based on the matrix measure theory is proposed.The closed-loop multi-delay power system model with wide-area controller is presented from the general point of view.The sufficient condition to obtain the maximum allowable delay which ensures asymptotic stability of the closed-loop system is given based on the matrix measure theory.The simulation results verify its validity.
