چکیده:

Due to the rising use of nonlinear loads, such aspower supplies, adjustable speed drives, diode/thyristorrectifiers , harmonic currents and reactive power are injectedinto the power system which can degrade the power quality. Inthis paper, a novel method on the basis of the fundamentalactive current component that is determined from a RecursiveDiscrete Fourier Transform (RDFT) block has been proposedto calculate the reference source current and the referencecompensating current for shunt active power filters toeliminate harmonics and compensate the reactive power ofthree phase diode bridge rectifier with RL load and increasethe power quality. The proposed method is presented and it isapplied to the control system of the voltage source shunt activepower filter to examine the performance of the method. thesimulation results confirmed the effectiveness of this method
