Abstract

Efficient distribution of high-quality power for commercial, industrial and residential purposes is a major issue in Nigeria. The performance evaluation of Rumuomoi 11/0.415kV distribution network is the focus of this research work. It was done to determine the status of the power network for efficient performance. The Port Harcourt Electricity Distribution Company supplied the data used in this study. Rumuola 33kV injection substation consists of eight (8) 11kV outgoing feeders of which Rumuomoi distribution network is one of them. The network consists of twelve (12) distribution transformers.  The 11KV distribution network has a total load of 5.2MVA. The network was modelled using Electrical Transient Analyzer Program (ETAP 19.0) software. The Newton-Raphson power flow technique embedded in the software was used to run the load flow simulation. The simulation results showed that the performance status of the network was not satisfactory as there were violations of the statutory bus voltage limits and some of the transformers were overloaded. Using transformers of higher ratings in the weak buses and capacitor banks as improvement measures, the result showed significant improvement of the voltage profile. The load flow results before and after improvement were compared and there was 69.9% reduction in voltage drop, 41.2% reduction in kW losses and 70.7% reduction in kVAR losses after improvement.
