摘要

为了提高晶闸管控制串联电容器(TCSC)的稳定性和抑制其低频振荡，提出了一种基于模糊sugeno逻辑的比例积分控制器(PI)。该控制器与超前滞后控制器一起用于单机无限母线系统中的电力系统稳定器(PSS)。同时，设计了一种独立的模糊控制器用于PSS，以验证FPI控制器的性能。实现了三种控制器组合同时控制TCSC和PSS。仿真结果表明，所设计的模糊+PI (FPI)控制器对不同负载和故障具有较强的鲁棒性。

Design of fuzzy+PI controller in application of TCSC and PSS for power system stability improvement

This paper introduces a proportional integral (PI) controller according to Fuzzy-Sugeno logic (FPI) for a thyristor controlled series capacitor (TCSC) in order to improve the stability and to damp the low frequency oscillations. This controller is used with a lead-lag controller for a power system stabilizer (PSS) in a single-machine infinite-bus system. Also, an independent fuzzy controller for PSS is designed to demonstrate the capability of FPI controller. Three compositions of the controllers are implemented to control TCSC and PSS at the same time. Simulation results show that the designed fuzzy+PI (FPI) controller is robust against different loads and faults.
