本文提出一种电力系统智能PI稳定器的设计方法,它由两层决策系统、识别环节及智能PI控制环节组成。控制规律模仿人的经验、推理及决策,能随电力系统运行方式及工况的变化,保持向系统提供有效的控制,提高系统的稳定性。文中给出了这种智能PI稳定器的设计实例及非线性仿真结果。
In this paper, a design method of smart PI stabilizer for power system is proposed. It consists of a two-tier decision system, identification and intelligent PI control. Control laws imitate people’s experience, reasoning and decision-making, with the power system operating mode and working conditions change, to keep the system to provide effective control and improve system stability. The design examples and nonlinear simulation results of this intelligent PI stabilizer are given in this paper.
