Analysis Of Power Flow of Nigerian 330kv Grid System (Pre and Post) Using MATLAB
Subject area: Science,Engineering and Technology · Area of research: Power Optimisation and Power Analysis
Abstract
This paper assesses the reliability, stability and efficiency of the proposed (post reform) 10,000MW capacity 330kV grid and the extent to which it will provide solution to the numerous problems that presently plague the existing (pre reform) grid. Using MATLAB, load flow studies are first conducted on both the 31 bus system pre reform grid and the 49 bus system post reform grid using both the Gauss-Seidel and Newton-Raphson iteration methods. Furthermore, the grid is subjected to contingency assessment to determine its capacity to withstand various contingencies that practical power systems encounter. The results obtained show that the post reform grid is a great improvement on the pre reform grid.
