Load Flow Analysis of 132/33KV Power Network for Voltage Enhancement Using Static VAR Compensation (SVC) Technique
Subject area: Science,Engineering and Technology · Area of research: Power System
Abstract
The usage of flexible alternating current transmission systems (FACTS) equipment is crucial for improving the power network's parameters. The load flow analysis and voltage profile enhancement of 132/33kV distribution network in Benin City were the main subjects of this study, both with and without the application of the Static Var Compensator (SVC) compensation technology. In order to show the effects of the static var compensator (SVC) on the power network for voltage enhancement, the study employed Electrical Transient Analyzer Program (ETAP) software to model the single line diagram of the network and execute the load flow simulation.The load flow simulation results showed that transformers T1 (116.2%), T2 (110.8%), T3 (191.8%), and T4 (110.5%) were overloaded according to the IEC standard that states that the constructive lifespan of the equipment will be shortened by continuous loading of the oil-immersed transformers above the limit of 80%.Bus 5 was observed to be the most overloaded bus. SVC of 150 MVAR was installed at the weak buses for reactive power compensation and the transformers upgraded to 75MVA, the load flow analysis results showed that the voltage profile improved significantly and there was reduction in the overloading of the transformers; T1 (78.5%), T2 (75%), T3 (61.5%), and T4 (74.8%), to increase the life span of the transformers.
