| 摘 要： | 电力系统暂态稳定性的研究,对保证电网的安全与稳定具有重要的意义。文中提出了一种基于模糊控制的多机系统暂态稳定分析方法,该方法将模糊控制和电力系统稳定性理论有机的结合在一起,以模糊集合论、模糊语言变量及模糊逻辑推理为基础,将发电机励磁系统的控制策略转化为模糊规则的形式,从而实现对多机系统的模糊控制。通过Matlab软件对三机系统进行数值仿真表明,与独立设计的AVR/PSS励磁控制器相比,以△ω、△ω为输入变量的模糊控制能更加有效的提高系统的暂态稳定性能,系统在不同的故障情况下具备较强的鲁棒性。

| Abstract: | The transient stability researching of power system, which has a vital meaning for insuring the safe and stability of the grid. This paper proposes a method of analyzing transient stability of multi-machine power system based on the fuzzy control. The method can combine the fuzzy control and the theory of power system stability organically, which is based on the fuzzy set theory, fuzzy language variable and fuzzy logic inference. It can convert control strategy of excitation into the fuzzy rule, thus realiz... |
