| 摘 要： | 发电机励磁系统与SVC对远距离输电系统的暂态稳定性有很大的影响。文中采用模糊控制的思想,对发电机励磁和静止无功发生器SVC同时进行协调控制和调节。该方法是以模糊集合论、模糊语言变量及模糊逻辑推理为基础,将发电机励磁与SVC的协调控制策略转化为模糊规则的形式,从而实现了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,与常规的AVR/PSS励磁控制器和PIDSVC控制器相比,以Δω、Δω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,同时也说明了协调控制在阻尼振荡和增强电压稳定性上的有效性。

| Abstract: | The transient stability of a long transmission system can be significantly influenced by the action of excitation system and SVC. The SVC and excitation controls for generator are proposed to make rotor angle and voltage stable by the fuzzy control. The method is based on the fuzzy set theory,fuzzy language variable and fuzzy logic inference. It can convert coordinated control strategy of excitation and SVC into the fuzzy rule,and realizing the fuzzy control of multi-machine power system. The numerical simu... |
