Shunt hybrid active power filter（ APF） compounds the characteristics of active technology and passive technology. The harmonic current detection method of ip-iqbased on instantaneous reactive power theory is studied,and the simulation models of shunt hybrid active power filter are established. The simulation results by matlab showthat shunt hybrid active power filter based on instantaneous reactive power theory has good dynamic tracking performance,and can detect the harmonic components effectively and compensate the harmonic components,which complete the role of harmonic suppression.
