Description
Summary:With the widespread use of harmonic generating devices, the control of harmonic currents to maintain a high level of power quality is becoming increasingly important. An effective way for harmonic suppression is the harmonic compensation by using active power filter (APF). This article presents a comprehensive survey of active power filter control strategies put forward recently. Many control techniques have been designed, developed, and realized for active filters in recent years. All the techniques are analyzed mathematically, and simulation results are obtained which are being compared in terms of its compensation performance with different parameters under steady state condition. The techniques analyzed are the PQ theory, Synchronous Reference Frame Theory (SRF), SRF theory without synchronizing circuit like phase lock loop also called instantaneous current component theory and finally modified SRF theory. Simulation results are obtained under sinusoidal balanced voltage source balanced load condition. Finally, shunt active power filter is applied to BLDC drive application. THD plots with and without APF are presented.
