摘要

本文讨论了采用基于模糊理论的分布式潮流调节器(DPFC)来提高电力系统的稳定性。本文的工作目标是设计一种针对低频振荡的振荡阻尼控制器，从而改善电力系统的动态稳定性。作为统一潮流调节器(UPFC)的衍生产品，该设备由并联和串联控制器组成，可以安装在两个电气区域之间的传输线上。以单机无限总线(SMIB)系统为分析对象，采用PI控制的DPFC和模糊控制的DPFC。在MATLAB/Simulink环境下，利用opal - rt5600实时数字模拟器进行了完整的案例研究。研究结果的意义在于具有较好的稳定性和稳定的供电能力。实例分析结果表明，该模型通过抑制功率振荡来提高系统稳定性是有效的。

Fuzzy Theory Based Distributed Power Flow Conditioner to Enhance Power System Dynamic Stability

This paper discusses about improving power system stability by employing a Fuzzy Theory based Distributive Power Flow Conditioner (DPFC). The goal of the work presented in this paper is to design an oscillation damping controller aiming at oscillations which has low frequency, thereby embellishing the dynamic stability of a power system. As a derivative of Unified Power Flow Conditioner (UPFC), this device consists of shunt and series controllers that can be installed in a transmission line between the two electrical areas. Single Machine Infinite Bus (SMIB) system is considered for analysis, by employing PI controlled DPFC and Fuzzy controlled DPFC. The complete case study is presented based on MATLAB/Simulink environment by using OPAL-RT 5600 Real-time digital Simulator. The significance of the results are better stability and constant power supply. Case study results showcase the validation of proposed model to improve the system stability by damping the power oscillations.
