A METHOD TO DETERMINE A SINGLE NUMERICAL VALUE FOR EACTIVE POWER IN NON-LINEAR SYSTEMS
Journal Title: Journal of Science And Arts - Year 2013, Vol 25, Issue 4
Abstract
Classical apparent power decompositions do not fulfill the conditions caused by the presence of harmonics. In harmonic polluted system, the proposed power definitions should be able to determine an accurate value for capacitance power to improve power factor of system. In this aper we modify, by means of instantaneous power equations, the method suggested by Khalsa - Zhang and proposes a new definition for reactive power in non-sinusoidal system. The new definition correctly gives a single numerical equivalent value of reactive power and can be easily applied to calculate the apacitance power. The application of this definition is illustrated with a simple example.
