Three Phase Active Conditioner for Harmonics Mitigation

The Shunt Active Power Filter is a very essential tool to remove harmonic currents and to reimburse reactive power for nonlinear loads. The fundamental standard of process of a Shunt Active Power Filter is to introduce an appropriate non-sinusoidal current (compensating current) into the system at the point of common coupling. This research work focuses on the time-domain approach for three-phase Shunt Active Power Filters through an effective algorithm. A fundamental outline and evaluation of the performance of existing improved algorithms for active power filters are presented. An enhanced approach based on time domain technique is proposed based on various complicated power quality problems and various compensation functions. It is observed that the proposed algorithm provides has shorter response time delay when compared with the conventional approaches. Therefore, the proposed approach can accurately attain various compensating current references.
