Abstract

The wide-area damping control with network communication time delay is investigated. Firstly, a fuzzy logic wide-area damping controller (FLWADC) based on the Mamdani model is designed without considering time delay. Then, a delay-compensated input is introduced to design an FLWADC with delay compensation (FLWADC-DC) in order to alleviate the effect of time delay on system performance. Delay compensation makes controller design complicated. Therefore, on the premise that the performance of the system is not undermined conspicuously, the fuzzy rules are decreased. Case studies based on four-machine two-area power system are carried out in Matlab/SimPowerSystem and TrueTime toolbox, and simulation results illustrate that the FLWADC-DC controller performs better than the FLWADC controller and the conventional WADC in time delay environments.
