Use of flexible alternating current transmission systems (facts) to improve the power flow control in the Nigeria transmission network

Abstract

This paper gives an overview of the Nigeria power transmission network with its associated mode of compensation as it relates to voltage drops and power losses. It also highlights the use and benefits to be derived from FACTS devices over conventional control devices employed in the present network in Nigeria. The study revealed that reactors, capacitors and tap changers used mainly in the Nigeria power network are sluggish and mechanical controlled and do not satisfy rapid changes in transmission network parameters. It identified areas in the network with low voltages and high power losses where FACTS devices can be injected in the Nigeria 330KV lines to increase transmission capabilities and boost power output to the national grid with a view to improving efficiency and reliability of power supply to consumers.
