A real-time closed-loop controller system used for controlling dynamic power filters under rapidly varying nonlinear loading conditions, is tested and evaluated. With the aid of a dedicated microprocessor system, using correlation algorithms, real-time reference signals for a dynamic compensation system are generated. In order to facilitate a cost effective compensation system, separate compensation of the fundamental reactive power component and the harmonic components is further investigated. A total algorithm time of 312[mu]s in a 50 Hz system is achieved, providing accurate compensation effort up to the 21st power system harmonic.
