Active power line conditioner with a neural network control scheme

A new control scheme based on artificial neural network (ANN) for a voltage-type active power line conditioner (APLC) is proposed. APLC is a very efficient apparatus for compensating harmonics caused by nonlinear loads. The proposed NN controller can provide appropriate switch control signals for APLC to generate compensation currents to reduce wave distortion in single phase, three-phases three-wires and three-phases four-wires distribution system. The training data are obtained using evolutionary algorithms. Computer simulations confirm the validity of the proposed NN controller.
