摘　　要：在现代电力系统中,统一潮流控制器(UPFC)是调节电压和潮流的有效手段。该文提出一种用遗传算法优化参数的基于径向函数单一神经元的神经网络(RBFNN)和TS模糊控制策略综合而成的统一潮流控制器设计方案,TS模糊控制策略应用非线性规则设计了更为有效的控制器,使用RBFNN避免了产生控制器的训练样本,同时利用GA全局优化TS模糊控制的参数,从而提高系统的暂态稳定性。经验证,该方案比传统的PI控制策略具有更好的系统振荡阻尼性能。The unified power flow controller (UPFC) has been proved to be an effective means for regulating voltage and power flow in modern power systems.In this paper, an integrated approach of RBFNN and TS-fuzzy scheme with a genetic optimization of their parameters are presented to design UPFC controller for improving transient stability performance of power system.TS-fuzzy scheme applies nonlinear rules to avoid producing training samples of RBFNN. Case studies show that this approach exhibits better damping performance than conventional PI controller.
