Real-time application of shunt active power filter dynamic compensation using real-time windows target

SUMMARY In this contribution, a control strategy in phase coordinates abc is proposed as the reference current generator to be used by the shunt active power filter (APF) compensation device. The development of the proposed reference current generator is described in detail. Its control design is kept simple, and transformation between different frameworks is not needed, thus allowing the control strategy to be applicable for both three‐phase and single‐phase electric systems maintaining theoretical and practical advantages. The proposed control strategy for the reference current generator is tested using Matlab/Simulink® with the incorporation of the Real‐Time Workshop® for the simulation of the shunt APF compensation in real time. Based on the reported real‐time application, it is possible to obtain simulation conditions that are close to the true real‐time environment under study using only a single computer, giving accurate results with relatively low‐cost hardware and providing a more complete evaluation of the applied control strategy. The dynamic behavior and performance of the shunt APF, using the proposed reference current calculator, have shown remarkable results. Copyright © 2012 John Wiley & Sons, Ltd.
