Abstract

Line losses in transmission lines constitute one of the major problems affecting power generation and distribution systems. Losses have been found to affect the overall efficiency of a system. Therefore, to increase the efficiency of any system, losses must be minimized. This paper carried out a comprehensive study and analysis of line losses associated with Nigeria 330-kV power transmission lines. The work includes the power-flow analysis carried out on the existing network using both the Newton-Raphson (N-R)written in code-based MATLAB and the model-based N-R in Power World Simulator (PWS) environment. The power-flow analysis was further subjected to contingency analysis and simulation using the N-R in PWS. Two load-flows were performed to reveal voltage violated buses.The results showed that the bus voltages outside the statutory limit of 0.95-1.05p.u(i.e 313.5-346.5kV) occurred at buses2-Birnin-Kebbi (0.9183pu), bus 9 Akangba (0.937pu), bus 18-Onitsha (0.935pu), bus 20-New-Haven (0.920pu), bus 25-Kaduna (0.9233pu), bus 26-Kano (0.776pu), bus 22-Jos (0.8192pu) and bus 28-Gombe (0.7247pu) under normal uncompensated condition. Capacitive shunt compensation was applied on these buses and the results recorded appreciable loss reduction (about 18.35%). The result of the single line contingency analysis for uncompensated and compensated indicates a total of 335 and 25 voltage bus violations respectively.
