New Simulink control block for single phase shunt active power filters

Harmonic distortion introduced by nonlinear loads in the electric system is hard to measure and anticipate, and the effects are harmful to other loads. To compensate these drawbacks, usually active power filters are used, but their performance depends on the method used to generate the reference current, and on the parameters of the filter. This paper presents a new Matlab Simulink control block which allows the rapid tuning of filter´s parameters, enables the selection of one of the six most usual control algorithms, and also can generate code for future implementation on microcontrollers.
