Electric Power Transmission Enhancement: A Case of Nigerian Electric Power Grid

Increase in economic activities resulting from increase in population and social advancement has led to increase in electrical energy demands. This has increased the burdens on the existing transmission assets and in some cases, has caused the loading of the transmission assets beyond their design limits with consequent reduction in power quality and power outages in extreme cases. Many techniques have been developed to enhance the capabilities of the power grids. This paper looks into these techniques with the view to exploring their applicability to the Nigerian 330KV electric power grid, towards seeking ways to enhancing the performance of the grid for better asset utilization. A typical transmission line in the grid was modeled to assess its strengths and weaknesses. Enhancement techniques were then applied to assess their impacts on the line.
