چکیده
This paper describes the application of a new fuzzy based control strategy to a three-phase shunt active power filter for harmonics minimization and reactive power compensation required by a variable non-linear load. To improve dynamic behaviour of shunt active power filter and make it robust under wide range of load variations, the value of load current is considered as an input of fuzzy controller. The proposed scheme is extensively tested for wide range of variable load current under stochastic conditions and results are found to be quite satisfactory to improve dynamic behaviour of shunt active power filter and mitigate harmonics from the utility current. Key-Words: Shunt active power filter, Adaptive control, Harmonics compensation, Fuzzy logic controller, Power quality, Power factor correction
