Comparison of various reactive power definitions in non sinusoidal networks with the practical data of electrical arc furnace

In the non sinusoidal networks, seven of the most famous power decompositions, proposed by Budeanu, Fryze, Kimbark, Shepherd and Zakikhani, Sharon, Kusters and Moore, and Czarnecki are widely recognized. In this study all of above reactive power definitions are simulated in MATLAB software. By using some statistic indices such as average and standard deviation applied to a huge number of data collected from eight Electric Arc Furnaces (EAFs) installed in Mobarakeh steel industry, Isfahan, Iran, the reactive power definitions are compared to each other from different ways. Also the mean of the seven famous definitions is considered as criteria and the farness of various definitions from it are compared to each other using proposed Mean Farness from Q, (MFQ) and Mean Farness from D, (MFD) indices.
