Abstract

This paper presents the IEEE 1459-2010 based approach to assess the power quality in the medium voltage network. Active, reactive and apparent power components, based on the characteristic harmonic current and voltage are assessed in details. The properties of non-fundamental components and power flow are discussed. The unbalanced and non-sinusoidal three-phase power components are calculated on the basis of RMS voltage and current waveforms obtained by measurement with the PQSCADA and PQElspec software. Harmonic components of the measured waveforms are calculated using Fourier analysis. These contents are used to evaluate and analyse the components according to IEEE 1459-2010. The case study of the metropolitan municipality in Johannesburg shows firstly that the harmonic frequencies are not taken into account in the power consumption estimation. Secondly, the distorted voltage or current causes an increase in the deviation of the underestimated power consumption, which is the difference between fundamental active power and total active power. The results indicate an increase of fifth and seventh harmonic voltage at certain moments at the Point of Common Coupling (PCC), probably due to network impedance. This is however at the expenses of the power utility.
