Abstract
Power system insecurity often leads to frequent power system collapse. Experience has shown that power utility companies are generally poor in network argumentation and planning. For example, it is required that any new project must be simulated to ascertain its effects on networks before carrying out the construction. The simulation could be used to investigate the bus voltage profile, power flow, losses, overvoltage condition, etc. Consequently, this paper presents a Newton-Raphson algorithm for power flow solution and the application of the developed Q-basic computer software package to a large power system network. It involves the formulation of algorithms and development of flowcharts which were used to determine the steady-state operating conditions of buses, generation, branch power flows and circuit system losses of the case study network considered. The results obtained are presented and discussed. The fast convergence of the system at the fifth iteration confirmed the effectiveness of the software and the accuracy of the results. Having previously tested the software with a known solution network and work fine, suggest the results obtained are accurate and reliable. Transmission lines with high reactive power need the installation of equipment capable of reducing the reactive power. Buses with voltage values a little less than acceptable standard needs improvement.
