P.F Corrections in High Power Winding Rotor of Induction Motors Used on Board Ship

Abstract

Induction motors is popularly used on board ship for various machinery. In sea environment
Induction motors are used due to robust construction, low cost, simple, high reliability factor. Maximum of
power is utilized by these types of motors. Since the loads are inductive in nature it consumes more reactive
powers. This causes increase in current and the consumption of active power increases. If the power factors
lags for certain level then there is chance of black out. Therefore to avoid such problems we must supply
extra reactive power to the motor. In shipping industry multiple large motors are induction motors, so it is
needed to improve power factor correction by adding capacitive loads. There is a demand to improve the
power factor for good power & fuel efficiency. Furthermore this paper proposed for power factor
improvement in induction motors by using fine static VAR capacitor.
