Effective and efficient electric power transmission is a major concern in Nigeria. Electric power transmission is the link between the generating companies and the distribution companies in Nigeria. This research work is to ascertain the status of Owerri 132kV/33kV Transmission Network for better performance with Newton Raphson method using Static VAR Compensators to solve the problem of under voltage, optimize the system for better power delivery by placing Static VAR Compensators to minimize Power System losses and maximize power transfer by its equivalent model using ETAP 7.0. The data used for this research work were obtained from the Transmission Company of Nigeria TCN (Owerri 132kV/33kV T/S) in Imo State. The Network consist of 132kV lines, ALAOJI I and ALAOJI 2 with the Six (6) 33kV Feeders: Mbaise 33kV, Owerri main 33kV, Owerri line 2, 332kV, Oguta 33kV, Okigwe 33kV and Orlu 33kV with a total load 152.42 MVA; The 132kV Substation has two (2) 60MVA transformers and one (1) 45MVA transformer called Mobitra.. The result of the simulation showed that transformers buses were over loaded beyond their capacities. The introduction of Static VAR Compensators at the 132kV Buses showed that there was an increase of Load MW by 3% and a reduction of Load MVAR by 49.37% when a capacity 52.9MVAR from the VAR Compensator was introduced at the 132kV buses. The simulated result showed an optimization of existing Network from the enhanced voltage, adequate power supply and a reduction of the total power loss from 22.0MW to 21.181MW representing a 4% reduction in load MW as seen from the simulation of the modeled 132kV/33kV Network.
