Enhanced Power Quality Compensation of Shunt Active Power Filters Without Harmonic Detection Schemes

Shunt active power filters (SAP F) implemented without harmonic detection schemes compensate simultaneously harmonic distortion and reactive power of the load. Their compensation capabilities, however, are limited by the SAP F power converter rating. Such a restriction can be minimized if the level...

Descripción
Sumario:Shunt active power filters (SAP F) implemented without harmonic detection schemes compensate simultaneously harmonic distortion and reactive power of the load. Their compensation capabilities, however, are limited by the SAP F power converter rating. Such a restriction can be minimized if the level of the reactive power correction is managed. An estimation scheme for determining the filter currents is introduced to manage the compensation of reactive power. The effectiveness of the proposed control strategy is ensured by introducing a feedforward scheme on the DC − link regulation. Also, a robust control based on adaptive pole placement regulates the grid currents. Experimental results are shown for demonstrating the performance of the proposed SAP F system.
