Power Factor Investigation

This makes it necessary to use suitable means to correct the power factor. This paper examines the use of the synchronous motor for power factor correction. There are several ways of defining power factor depending on the context of study. However, all the definitions come from the understanding that electrical power manifests in three ways. These are real power denoted as P (also known as true power or active power), reactive power denoted as Q, and apparent power denoted as |S| (Singh, 2008). Apparent power is the magnitude of complex power denote as “S” which is the vector sum of real power and reactive power (Singh, 2008). Each of the three manifestations of power has a different measure. The unit of measurement of real power is in watts (W) that of apparent power is Voltage-Amperes (VA), while that of apparent power is in Reactive-Volt-Amperes (VAR) (Meier, 2006). The ratio obtained by comparing real power to apparent power is the power factor. ...Show more
