Investigation of Electromagnetic Transient in Power Systems Using E.M.T.P. - R.V

Abstract

Over the years, electromagnetic transient in power systems has been of great
concern to the power industries. This is because its effect on transmission lines is
enormous. Various research works have been conducted in which several
controllers were utilized to enhance the stability of modern power systems.
Therefore, the investigation of electromagnetic transient in power systems using
Electro-Magnetic Transient Program – Restructured Version (E.M.T.P. –R.V.),
which is a comprehensive analysis of transient stability issues, proposed mitigation
strategies, and evaluation of the impact of renewable energy integration system
stability using simulation studies have been presented. Lightning and switching
surges are the dominant and most frequent causes of power system outages. These
outages have significant effect on the economy. The protection of electrical systems
against electromagnetic transients caused by lightning and switching surges is
especially difficult because of the unpredictability of the transients and complexity
of their interaction with the electrical systems. Lightning transient that propagates
through transmission lines affecting equipment and causing insulation
breakdown, needs to be properly handled to minimize its effect of instability on
our transmission lines. The arrester investigated is the Zinc Oxide (ZnO) arrester.
