Abstract

A method for controlling the excitation of large synchronous motors is proposed. The proposed control method is based on applying a fuzzy logic controller. The membership functions of input parameters (deviations of the power factor and reactive power absorption level at the node), as well as the output parameter (the excitation voltage) are presented. A rule base is given, the application of which makes it possible to produce an output signal depending on changes in the power factor and reactive power absorption at the load node. The transients triggered when a large induction load is connected to the power supply node of a synchronous motor equipped with a fuzzy logic controller are studied. The effectiveness of the proposed control method has been demonstrated.
