Abstract
Induction motors are widely used in industrial production processes. Use of an induction motor will result in increased lagging power factor. This power factor must be corrected by adding capacitors. If not, the result is the penalty of larger kVA burdens to the interconnected system. The synchronous machine, with the aid of an intelligent excitation controller, can control power factor to reduce the plant reactive loading to the connected system. This paper provides information regarding to the digital excitation system. In this system dsp320F2811 is used. Different modes like power factor control and var operation are also discussed. Simulation of the proposed topology is given. This paper will also address to the typical protections, which are included in this excitation system.
