Performance of Smes Unit on Artificial Neural Network Based Multi-Area Agc Scheme

Abstract

The main objective of this paper is to develop Fuzzy controller to analyse the performance of
instantaneous real active and reactive power (p–q) control strategy for extracting reference currents of
shunt active filters under balanced, un-balanced and balanced non-sinusoidal conditions. When the supply
voltages are balanced and sinusoidal, the all control strategies are converge to the same compensation
characteristics; However, the supply voltages are distorted and/or un-balanced sinusoidal, these control
strategies result in different degrees of compensation in harmonics. With PI controller the p-q control
strategy unable to yield an adequate solution when source voltages are not ideal. Extensive simulations
are carried out with Fuzzy controller for p–q control strategy under different main voltages. The 3-ph 4-
wire SHAF system is also implemented on a Real Time Digital Simulator (RT DS Hardware) to further
verify its effectiveness. The detailed simulation and RT DS Hardware results are included.
