Study on Performance of Non-Linear Reactive Power Compensation by Using Active Power Filter under Load Conditions

The paper analyses and examines the efficiency of non-linear reactive power compensation when use the active power filter controlled by an algorithm based on the theory of CPC. The developed physical model of 3-phase active filter has been presented and results of its performance in the system so the linear load and nonlinear RL type are discussed. Particular attention was put on its operation in transient conditions. Based on both simulation and investigation results appropriate practical conclusions are formulated.
