Abstract
This work analyses the line losses in the Nigeria 330kv, interconnected power system. It devised a dependable solution model and strategy for minimization of power losses on lines in the Nigeria 330kV grid. Unfortunately, electricity is not always used in large demand in a location it is been generated. So, long cables are used to transmit the generated electricity through overhead lines, this transmission does not take place without encountering loses. Theload flow analysis was carried out on the existing 58bus with the view of estimating the real and reactive power flow, bus voltages and line power losses in the 330kv network using Newton-Raphson iterative algorithm. The simulation result of the 58buses shows that (6) six buses did not satisfy the statutory voltage limit of 0.95pu to 1.05pu. The bus voltage profile shows that most of the violated buses are in the northern part of Nigeria. The simulation result of the study system line active power loss showed that there was 4.3232 pu line active power loss which is about 432 mw 100 mw base power value. Major system active power losses were witness in the southern part Nigeria. The problem of low voltage was solved by the use of facts device using continuation power flow method, the violated buses were cleared by optimal placement of UPFC along Kaduna – Jos transmission line. The losses were reduced successfully to 32.39% by combine effort of multiple optimal placement of UPFC along Onitsha - Alaoji transmission line.
