VOLTAGE VIOLATION ON THE 330KV POWER NETWORK OF NIGERIA WITHOUT FLEXIBLE ALTERNATING CURRENT TRANSMISSION DEVICE

Abstract

This paper on Identification of voltage violations on the power network of Nigeria without flexible alternating current transmission device investigates the 58 buses, 330Kv Nigeria transmission Lines. The work was on 58 buses, 330kv Nigeria transmission line network. It examined some major voltage control methods which are necessary and vital in controlling voltage violations on the network. The specific objectives are : To characterize the 58 Bus Nigeria interconnected power network, To model the 58 Bus 330Kv Nigeria Transmission Network, To Simulate the 58 Bus Nigeria 330kv Transmission Network and to identify the voltage violations from the simulation results. To identify the voltage violations on the transmission lines of 58 Buses, 330kv Nigeria network was modelled and load flow simulation was done using PSAT in MATLAB environment just to initialise the dynamic simulation of the System and also the violated buses were noted. The methods used in achieving the specific objectives were properly explained. The result obtained shows thatsix buses that had violated voltages were Kano-0.936895pu, Gombe-0.908595pu, Damaturu-0.906397pu, Maiduguri-0.897593pu, Yola –0.9012pu, Jos -0.93719pu. This was done using a Test case one, which contains no FACTS device inserted in the study system.
