“…They show that the significant harmonic voltage levels are occurring on these systems at the third, fifth, and seventh harmonics. In Reference [10], the same authors report measurements at 6 customers' sites: 4 residential/commercial and 2 light industrial. The industrial customers are reported to have low penetrations of large power electronic equipment.…”

“…This method must account for the unknown magnitude and location of the harmonic sources as well as the changes in the system operating configuration which will be encountered. There is an immediate need for this methodology as a number of recent studies have reported harmonic voltages at or near levels where filtering is desirable [6][7][8][9][10].…”

Abstract-A planning methodology for distribution system harmonic filtering is proposed. The method is intended for use on radial distribution systems with no large harmonic sources. It is proposed that 60 hertz var planning be done first to allocate the var resources. Following this process, the harmonic filter planning can be readily accomplished. Characteristics of the distribution systems and the harmonic sources are exploited to provide a practical filter planning technique which is effective and efficient.

“…However, the power electronic devices inject the harmonic current and reactive current to the power system which cannot ignore, lead the current and voltage waveform distortion. In addition, with the various kinds of digital electrical equipment and precision electronic instruments' wide use, the requirements of power quality in power system will be more and more strict and even harsh [1][2][3][4].…”

Abstract-At present, there are many methods to improve the compensation performance of active power filter (APF). However, to improve the reliability of APF, dead-time between two IGBT switches in the same bridge must be set large enough to guarantee the IGBT operating safely, which will impact the output performance of APF. This paper proposes a modeling method on a specific order harmonic to investigate the dead-time's influence to the compensation performance of APF. The theoretical analysis is well verified by the simulation results. At last, some methods are recommended to minimize the unexpected effect caused by dead-time.

“…The simultaneous measurements of three-phase harmonic currents and voltages from the different load sectors allow Manuscript for the effect on the net distribution system harmonic voltage and current to be determined. The coordinated approach in obtaining the results has overcome some of the problems with synchronizing and reporting data [10], [11]. An enormous amount of data over a three-year period has been downloaded and available for analysis.…”

Abstract-Harmonic monitoring has become an important tool for harmonic management in distribution system. A comprehensive harmonic monitoring program has been designed and implemented on a typical electrical medium-voltage distribution system in Australia. The monitoring program involved measurements of the three-phase harmonic currents and voltages from the residential, commercial, and industrial load sectors. Data over a three year period have been downloaded and available for analysis. The large amount of acquired data makes it difficult to identify operational events that significantly impact the harmonics generated on the system. More sophisticated analysis methods are required to automatically determine which part of the measurement data are of importance. Based on this information, a closer inspection of smaller data sets can then be carried out to determine the reasons for its detection. In this paper, we classify the measurement data using unsupervised learning based on clustering techniques using the minimum message length technique, which can provide the engineers with a rapid, visually oriented method of evaluating the underlying operational information contained within the clusters. Supervised learning is then used to describe the generated clusters and to predict the occurrences of unusual clusters in future measurement data.
