摘要
暂态稳定性问题是目前电力系统遇到的几种主要的稳定稳定性问题之一。由于SVC等电力电子型FACTS设备的快速响应特性,它们不仅能够完成稳态潮流控制,还能够提高电力系统动态和暂态稳定性。传统的SVC模糊逻辑控制器均以被控量的偏差和偏差变化率为输入,以SVC的电纳B_(svc)直接作为控制输出来进行设计。提出一种新的能够在暂态过程中动态调整传统SVC一阶动态控制器增益的模糊逻辑控制器的设计方法。该模糊逻辑控制器以传统SVC一阶动态控制增益为输出。间接完成SVC的控制。通过安德森3机9节点算例系统验证了该模糊逻辑控制器的有效性。
Trausient stability is one of the most important stability problems in power system. Because of the rapid response characteristics, SVC can not only be used to control the steady power flow, but also be used to improve the dynamic and traosient stability of power system. Conventional SVC fuzzy logic controllers adopt error and changed error as inputs and the suseeptance of SVC as the outputs directly. A novel fuzzy logic controller which can dynamically adjust the gain of the SVC first order dynamic vuntroller is proposed in this paper. Case studies on Anderson 3-machine 9-bus system demonstrate that the fuzzy logic controller is effeetive and valid.
