Keywords:
Load flow, Loss minimization, Newton-Raphson method, Power distribution, Reactive power loss, Real power loss, SubstationAbstract
The research presents an in-depth analysis of the Escravos oilfield for improved power distribution. In this research, Newton-Raphson method of solution was used to diagnose the Escravos power network to ascertain the present and proposed state of the network under investigation. Three scenarios were considered in the course of this evaluation, and appropriate steps were employed to remediate critically overloaded cables in line with the IEEE voltage regulatory standards. From the load flow report, when the system is powered by the main and alternative generating plants, the cumulative real and reactive power loss was recorded as , and . Results from the second scenario demand cable replacement from for smooth and normal operation of the distribution network. The effect of the replacement of cables 3, 4, 8 and 9 from was positive as the power loss value was minimized to with an increased average voltage profile of 99.85%.
