ADALINE-Based Shunt Active Power Filter for Power Quality Modification of Power System

This paper is aimed to develop the control strategy of harmonic current compensation for shunt active power filter (SAPF). When analyzing harmonic signal through adaptive linear filtering (ADALINE), the estimation accuracy of phase angle would be easily reduced due to power system frequency deviation. Therefore, the model of improved ADALINE with the frequency detection method is proposed to overcome this problem and then perform the compensation control. From the simulation results, the performance of proposed SAPF for the compensation of nonlinear harmonic currents can be verified and the requirements in IEEE Std. 519-2014 are met.
