This paper addresses the issue of power quality management in smart grids. Present development of smart grid technologies such as smart metering are continuously generating novel opportunities and breakthroughs for improving the distribution system performance. This paper proposes a novel approach to be implemented in the new generation of smart meters. This alternative method for harmonics and voltage...
The fast Fourier transform (FFT) is the most commonly used technique in power systems signals analysis. However, it is known that if the signal is not synchronized or in the presence of interharmonics, the spectral leakage may occur. To overcome this issue, several techniques are found in literature. The present paper will show a comparison between results of calculating the IEC 61000-4-7 harmonics...
The modern power systems are supplying an increasing number of non-linear loads like: double conversion systems, arc furnaces, arc discharging, high power cycloconverter (CCV) etc. These loads are harmonics and interharmonics sources. Therefore, it is important to measure interharmonics accurately. The Fast Fourier transform (FFT) is used for signal processing because of its computational efficiency...
