ENHANCING THE STABILITY OF THE NIGERIAN 132/33KV TRANSMISSION SYSTEM USING UNIFIED POWER FLOW CONTROLLER

This research presents enhancing the stability of the Nigerian 132/33KV transmission system unified using power flow controller. The work was embarked on with the aim of improving the stability and control of power flow fluctuation during transmission. The methods used were characterization of the New Haven 132/33KV transmission station to read the unstable bus via Newton Raphson load flow analysis. Unified Power Flow Controller (UPFC) was developed to stabilize the unstable bus characterized with load flow problem through series and shunt compensation processes. The controller was implemented with Simulink and then evaluated. The result showed that the voltage profile satisfy the Nigerian Electricity Regulatory Commission (NERC) standard for transmission network.
