Special Issue Information

Dear Colleagues,

We invite submissions to a Special Issue of the journal Energies on the topic of “Harmonic Sources Identification and Their Influence on Electrical Equipment”.

At present, the problem of power quality improving is becoming widespread, since electrical equipment based on semiconductor converter technology is used at any industrial facility. And this is typical not only for consumers with non-linear electrical loads, but also for consumers that do not distort the supply voltage. The development and implementation of distributed generation systems also leads to problems associated with distortion in voltage and current. In this case, it is important to determine the share contribution of distortion sources in the electrical grid. This is important not only in terms of penalties, but also in terms of equipment selection to reduce harmonic distortion.

In the conditions of a branched electrical network of an individual consumer, it is also necessary to determine the share contribution of distortion sources, since compensation for their influence should be carried out in those nodes where this leads to the greatest technical and economic effect. A large number of developed methods for identifying the contribution of distortion sources are known, but there are still no correct and approved methods and guidelines that allow identifying such a contribution.

This Special Issue has the aim of collecting and systematizing the latest achievements in the field of identifying the share contribution of distortion sources and compensating for their impact on consumers in systems with various energy sources. The topics of interest include but are not limited to:

  • methods of distortion sources identification;
  • modeling and simulation of nonlinear loads;
  • methods of power quality improvement;
  • economic aspects in conditions of reduced power quality;
  • impact of disturbing loads on supply networks and other electrical equipment;
  • harmonic problems in grids with distributed generation;
  • standardization and regulation.

This paper presents the electrical system factors having an influence on the work efficiency and performance of the LC passive harmonic filters (PHFs). Such filters are very often used in industries for the purpose of harmonics mitigation and reactive power compensation. Before their installation in the electrical system, many investigations should be performed in order to ensure their good design as well as work efficiency after connection. In this paper, the factors having an influence on the PHFs work efficiency and performance, such as the grid short-circuit power, primary grid voltage spectrum (voltage measured at the PCC before the filter connection), load reactive power and current characteristic harmonics, manufacturer filter parameters tolerance and filter-detuning phenomena are investigated. Most of the quoted factors are mentioned in the literature, but the novelty of this paper is that, based on the case study example of the single-tuned filter investigated in the laboratory, the influence of those factors on the filter work efficiency are demonstrated, and some solutions and recommendations are proposed. The studies are focused on the design of the single-tuned filter in the laboratory, and some simulation results are presented as well. Full article

In this article, a method that allows sharing responsibilities for the generation of harmonic currents between the utility and consumers powered by one point of common coupling (PCC) is addressed. For these purposes, mathematical modeling of the power supply system (PSS) with two consumers is carried out in order to introduce new indices using the simplest PSS structure as an example. Two indices are introduced that quantify the consumers’ contribution to the distortion of current and voltage at the PCC and that evaluate harmonic emission from the utility side. Experimental tests are carried out where both linear and nonlinear loads are considered, capacitive loads are taken into account, and harmonic distortions from the utility side are modeled to show the applicability of the indices in a wide range of load types. The experiments confirmed the theoretical results and illustrated that the quantitative assessment of the contributions is unambiguous. It suggests that the proposed criterion could be a reasonable basis for further tax policy on harmonic pollution for each consumer at the PCC and for the utility. Full article

The paper deals with issues of modeling nonlinear electrical loads of various types, such an uncontrolled rectifier, thyristor rectifier, thyristor power regulator and mixed equivalent nonlinear load. For these load types, existing analytical expressions were identified to determine the magnitudes of harmonic currents, and waveforms of currents were obtained during measurements in laboratory conditions with variable parameters of the grid impedance and load. The obtained results were compared, and it was found that the error in determining the magnitudes of harmonic currents can reach 60% for an individual load and 54% for an equivalent load. A more accurate method for determining the parameters of nonlinear electrical load is also proposed, which is based on the application of shunt harmonic filters. In laboratory conditions, it was found that when using the developed method, the error did not exceed 10% for an individual load and 14% for an equivalent load. Full article
