Application of Unified Power Flow Controller in Nigeria Power System for Improvement of Voltage Profile

With the increased rate of urbanization and industrialization, the Nigerian electric power system is being put under pressure, high power losses which has led to fluctuation in voltage level. In this work the Nigeria 330Kv network of 42 bus system was considered. Data for the analysis were obtained from Transmission Company of Nigeria National Control Centre, Osogbo TCN and MATLAB PSAT software with newton Raphson's solution method embedded in it was used to carry out the analysis. The results of the analysis showed that many of the bus voltages were outside the voltage limits of ±5 i.e 0.95pu 1.05pu . After compensation with Flexible AC Transmission System devices FACTs namely Unified Power Flow Controller UPFC which can be used to control power flow on a transmission line, the voltage profile almost flat with bus voltages within acceptable voltage limits. It is also evident that the UPFC is device that can used to combat the voltage problem in the Nigerian electric power system. Adikaibe James | Prof. Engr. F. O.
