Abstract:
The Calabar transmission network, which consists of 41 buses and 56 lines, was subjected to load flow studies and transient stability analyses. During a standard simulation of load flow analysis, buses 9, 50, and 54 had voltages of 66.681%, 66.96%, and 66.655%, respectively. However, after compensating the afflicted buses, the voltages on these buses improved by 16.89%, resulting in 96.112%, 98.887%, and 103%, respectively. Without compensators, the total network losses during normal load flow simulation are 16.511MW and 4004.872 Mvar. When compensation is applied, the overall network losses increase to 19.211MW and 2348.110 Mvar. Some transient cases were examined; these cases are 3-phase faults on bus 3 at 5 seconds. 50% fault on line 34 cleared after 15 seconds. ETAP 19.0 is utilized as a simulation tool since it has a superior network analysis performance. The purpose of this article is to analyze the Calabar transmission line network, with the results being used effective planning and extension energy sustainability. This work is being done in response to the energy issues in the area in order to improve performance and coordination. The Newton Raphson technique of load flow is being investigated the job because of its advantages of better and shorter iteration to solution
