In this article, the performance of shunt active filter for extracting the current references under steady and transient for both balanced and unbalanced conditions by using PI controller has been evaluated and wide-ranging simulations are carried out with PI controller for p q control strategy.Abstract:
By using a bulky amount of non-linear loads, power electronic equipments, commercial and even residential electrical equipments are causing deterioration of the quality of the electric supply through distortion of supply voltage. This will lead to development of more stringent requirements regarding harmonic current generation, which are found in IEEE519 and IEC61000. The active filters have been used to frontier the flow of harmonic currents in both transmission and distribution systems. But the presentation of the active power filter seems with various control strategies. This article gives the in depth analysis to evaluate the performance of shunt active filter for extracting the current references under steady and transient for both balanced and unbalanced conditions by using PI controller. The instantaneous real active and reactive power control strategy which is widely used in shunt active filter. The wide-ranging simulations are carried out with PI controller for p q control strategy for various voltage conditions.read more

Harmonic Mitigation Using Shunt Active Power Filter Under Various Loading Condition
TL;DR: The proposed p-q theory control strategy with PI controller and hysteresis controller for extraction of the current reference signal for SAPF is able to achieve better optimum total harmonic distortion (THD) and has been validated using numerical results, which justifies the extensibility of the strategy.
