Abstract

Rapid development of high power semiconductor devices with fast control features have given birth to several flexible AC transmission systems (FACTS) controllers to improve the power system performance. One of the advanced FACTS controllers is generalized unified power flow controller (GUPFC) or multi-converter UPFC, which can control bus voltage and both the real and reactive power flows of more than one line or even a sub-network. In this paper, dynamic performance of a GUPFC has been investigated using a new fuzzy logic based controller. The controller rules have been structured depending upon the relationship between the series inserted voltages in multi-line and the desired changes of real/reactive power flows in the power system. The effects of different types of controllers along with parameters of series transformers and transmission lines have been investigated through the control block models developed on a sample system in MATLAB SIMULINK. The effectiveness of the proposed scheme has been demonstrated through various case studies. Copyright © 2008 John Wiley & Sons, Ltd.

基于模糊规则的广义统一潮流控制器的研制

具有快速控制特性的大功率半导体器件的快速发展催生了多种灵活的交流传输系统(FACTS)控制器，以提高电力系统的性能。通用统一潮流控制器(GUPFC)或多变换器UPFC是一种先进的FACTS控制器，它可以控制母线电压以及多条线路甚至一个子网络的实潮流和无功潮流。本文采用一种新的基于模糊逻辑的控制器研究了GUPFC的动态性能。根据多线路中串联插入电压与电力系统中实际/无功潮流的期望变化之间的关系，构建了控制器规则。通过MATLAB SIMULINK开发的控制块模型，研究了不同类型的控制器对串联变压器和输电线路参数的影响。建议方案的有效性已通过多个个案研究得到证实。版权所有©2008 John Wiley & Sons, Ltd
