Reactive Energy Transfer Reduction Equipment for Low-Load Wound-Rotor Induction Motors

The power quality covers the means to conserve energy resources, such means consist in improving the power factor and judiciously managing the reactive energy in the power system. On the premise that for industrial consumers, the main consumers of reactive energy are the low-load induction motors and transformers, this paper presents a synchronization equipment (DISMAP) for a wound-rotor induction motor with a power of 2000 kW, which allows the increase of the power factor, significantly reducing the reactive energy consumption. The equipment presented was designed, built, tested and validated by tests carried out in the high-power laboratory.
