Transient Response of Power Networks to Pulse Inputs of Non-Standard Wave forms: Analysis and Case Studies

  1. Mohamed Mostafa Saied

Abstract

This study reveals and discusses intriguing situations that can cause electromagnetic transient stressors with unexpected magnitudes and time wave patterns in power networks. They may be caused, for instance, by atmospheric discharges that affect overhead power lines and/or underground cables, provided that the stimulating surges also feature a number of rather evenly spaced pulses of a repetitive nature. An s-domain mathematical model based on the distributed parameter analysis is presented. It considers the specifications of the impacted electricity network as well as the spectrum of the discharge surge current. Representative case studies are addressed. They show the dependence of the transient stresses on the networks’ parameters and loading conditions.
