“…This is a required indicator to understand learning outcomes. The most common indicators are: Current and voltage waveforms : Representation of the simulated electrical signals containing harmonic distortion visible to the eye (e.g., in Figure ). Root‐mean‐square values (V RMS for voltages and I RMS for currents) : They increase when harmonic distortion exists (Equations and ).

V_{R M S} = \sqrt{\sum_{n = 1}^{\infty} V_{n}^{2}}

I_{R M S} = \sqrt{\sum_{n = 1}^{\infty} I_{n}^{2}}

where n is the number of the harmonic, being 1 the fundamental.…”

In recent years the undergraduate engineering curriculum of several areas has started to incorporate the study of harmonic distortion on electrical systems. Several education simulation tools have been developed and investigated, most of them a short time ago. However, to the best of our knowledge, there is not any literature review on this topic. In this work, we present for the first time a systematic survey on educational tools to model and simulate the effect of power harmonics on industrial electrical networks. As a result, several improvement aspects have been identified and recommendations and implications for future research have been provided. For that, a retrospective study has been accomplished, showing a growing trend toward simulation and modeling. The key instructors’ perceptions to incorporate these practices are the ease of the teaching‐learning process and the importance of modeling and simulation in the industry. The main research challenge is the conduction of integral assessments that comprise both tools’ quality and use experience, and their contribution to achieve learning outcomes. Statistical tests should be used to validate the academic results obtained. This is a major challenge, since only a few of the existing studies incorporate such tests. Other implications for future research refer to the involvement of a higher number of students in the evaluations and the use of free software in the development of the applications.

“…The problem with the induction furnace [4][5][6] is that it introduces appreciable harmonic distortion in load current in the distribution system network. These unbalance load currents result in voltage fluctuations and imbalance due to the system impedance which affects the performance of other electric equipment [5][6] connected in the power system network. In addition, there is also an initial dip in the load current due to the presence of induction furnace in the distribution network.…”

The application of Distribution static synchronous compensator (DSTATCOM) with fuzzy controller in a distribution network with induction furnace load is investigated and presented in this paper. The problem with the induction furnace load is that it introduces appreciable amount of harmonic distortion in the power system network. The performances of other loads connected in the power system network are also affected because of the presence of induction furnace load. In this paper, the results obtained for the SIMULINK model illustrating the application of DSTATCOM with Fuzzy controller for reducing the harmonic distortion in the load current in the distribution network with induction furnace load, are presented.
