Amaize Peter, Adoghe Anthony, Awosope Claudius, Airoboman Abel, A Review of the Applications of FACTS Devices on Nigerian 330 kV Transmission System, Journal of Engineering and Applied Sciences, Volume 12,Issue 20, 2017, Pages 5182-5185, ISSN 1816-949x, jeasci.2017.5182.5185, (https://makhillpublications.co/view-article.php?doi=jeasci.2017.5182.5185) Abstract: This research presents a critical review of the application of FACTS devices into the Nigerian 330 kV network for the enhancement of bus voltages and the minimization of the transmission system power loss. Available publications were critically examined with references to show these devices have been applied to power systems. This research provides vital information for power system operators and researchers on how to incorporate FACTS devices into the Nigerian power transmission system.
