Abstract
Line losses ill transmission lilies constitute one of the llllljor problt!llls affecting power generation and distribution systems. Losses luwe beelt foulld to affect the overall ejJidency of a system. Therefore, to illcretUe the efficiency of any system, losses must be minimized, This paper carried out a comprehensive study alld analym of line losses associated with Nigeritz 330-kV power transmission lines. The work includes the power-flow analysis carrid out on the existilfg Mtwork using both the Newton-Rapltson (N-R)wrltten in code-btlsed MATLAB a1ld the model-based N-R ill Power World Simulator (PWS) environment. The power-flow analysis HillS further subjected to contingency analysis and silllukdion using the N-R in PWS. Two 101111-flows were performed to reveal voltage violated buses.The resulb showed that the bus voltages outsith the statutory limit of 0.95- 1.05p.u(i.e 313.5 - 346.5kV) occurred at buses2-Bimi1JKebbi (0.9183pu), bus 9 Akangba (0.937pu), bus 18-0nitslul (0.935pu), bus 20-New-Htn~e~~ (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 conditio11. CfiiHICitive shunt compensation was applkd on these buses and the results recorded appreciable loss rethlction (about 111.35%). The result of the 11ingk line contiiJgency analyllis for uncompeMated and compen~~ated indicates a total of 335 alld 25 voltage bus violl.ltions respectively
