The procedure for calculating controller parameters of the APFs implemented into a multibus industrial power system for harmonic voltage mitigation is presented. The node-voltage-detection control strategy is applied and the basic controller parameters are found under the condition that the demanded THD factors at the buses where the APFs are placed will be obtained. A cooperative control of several APFs without mutual communication is proposed, simulated, and experimentally verified. By tuning the controller gains without considering the power circuit parameters, all APFs used tend to share harmonic load currents approximately equally regardless of the operation modes of the nonlinear loads in different parts of the power system.

Active power filters have properties in rapid reflection, better compensation and the ability in dynamic suppression. An aviation series active power filter based on ip，iq method according to the theory of instantaneous reactive power was designed and simulated with PSIM in this paper. Simulation result states that the filter can compensate harmonic voltage sources, consume harmonic current, and it has good dynamic and steady properties. The result gives a way in aviation series active power filter’s design and application.
