Automatic Power Factor Correction of Synchronous Motor

I. D. Chaudhary

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. 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 provide informations of power factor correction of synchronous motor. The power factor measured at the input terminals of a synchronous motor is adjusted to a reference value. If the measured power factor is different than the required reference value, error signal is generated. This error signal is evaluated by PI controller to obtain a control signal for the synchronous motor excitation circuit since the power factor of a synchronous motor can be controlled and held at a desired value by adjusting the excitation current.
