The conventional extraction methods for harmonic and reactive currents is having inaccuracy, in case of distorted and unbalanced supply; non-linear and unbalanced load. Based on adaptive interference cancelling theory, a method is presented to estimate the harmonic, fundamental frequency unbalanced and reactive current components. A simulation is performed in MATLAB/SIMULINK environment which to verify the feasibility of the proposed method. This method can be useful for the dynamic compensation equipment such as static Var compensator, unified power quality conditioner and so on.falseAdaptive cancellation theory | Adaptive detection algorithm | Instantaneous power theory | Instantaneous symmetrical components | Shunt active power filter | Voltage source inverterConference Paper7 May 2015347103893cpConference Proceeding26
