Published by Ali BAGHERI, Mohsen ALIZADEH, Department of Electrical Engineering, Yadegar -e- Imam Khomeini (RAH) Shahre Rey Branch, Islamic Azad University, Tehran, Iran Abstract. One of the most important indices of power quality in distribution grids is the harmonic distortion, which can affect the reliability of the micro-grid. On the other hand, the growth ofContinue reading “Designing a Passive Filter for Reducing Harmonic Distortion in the Hybrid Micro-grid Including Wind Turbine, Solar Cell and Nonlinear Load”

Electrical Power Quality and Harmonic Concerns
Published by Chuck Gougler, International Association of Electrical Inspectors (IAEI) Magazine, Electrical Fundamentals – Electrical Power Quality and Harmonic Concerns, December 29, 2015 The Problem of Harmonics Harmonics are generated by nonlinear components in electrical systems, which distort the sine wave. Increasing usage of power electronics causes a corresponding increase in voltage distortion, or harmonics.Continue reading “Electrical Power Quality and Harmonic Concerns”

Inductors in Series
Published by Blaine Geddes In this article, you find a focus on series-connected inductors where ladder low pass filter structures consisting of series inductors and shunt capacitors are introduced. For inductors connected in series with no mutual flux coupling, the electrical effect is analogous to resistors connected in series and the individual inductance values areContinue reading “Inductors in Series”
