Experimental Study of Power Definitions in Non-sinusoidal Condition

Non-linear loads are widely used in power systems nowadays. This application leads to affect the power grid negatively by producing harmful harmonics in the form of non-sinusoidal waveforms. Hence, the definitions of reactive power in non-sinusoidal have been proposed by various researchers who each of them claims that his proposed definition is proper to be applied to defined the power definitions in non-sinusoidal conditions and under the effect of harmonics. In this paper, most of power definitions in non-sinusoidal situations are reviewed and studied. Also, the point views of each researcher are discussed and compared in details. Finally, to examine the validation of the proposed power definitions in in non-sinusoidal conditions a case study was carried out by building a circuit under harmonic effects to measure the power parameters using experimental platform and Matlab environment to provide a numerical comparison of the power values measured based on those different definitions.
