Voltage Profile Enhancement in the Nigeria 330kv Line Using Statcom
Subject area: Science,Engineering and Technology · Area of research: Electrical and Electronic Engineering
Abstract
This research examines bus voltages in the Nigeria 330kV interconnected power system. The work devised a dependable solution model and strategy for improving violated bus in the Nigerian 330kV line. Unfortunately, electricity is not always used in large demand in a location it is been generated due to the nature of the transmission line, there is possibility of experiencing low bus voltages, lines overload, frequency fluctuations and poor system damping in the power network, thereby making the stability of the network to be weak when subjected to fault conditions. Load flow analysis was carried out on the system with the view of estimating and analyzing the real and reactive power flow and bus voltages. The input data for the power flow analysis was obtain from TRANSCON (TCN), the data was fed into PSAT 2.1.8 in MATLAB 2018b environment and analyze using Newton-Raphson iterative algorithm. The simulation results of the 58buses shows that (6) six buses did not satisfy the statutory voltage limit of 0.95Pu to 1.05Pu.The buses that were out of the tolerance includes: Kano(0.9352Pu), Gombe (0.8979Pu), Damaturu (0.8942Pu), Maduguri (0.8845Pu), Yola (0.8898Pu) and Jos 0.9331Pu). The bus voltage profile shows that most of the violated buses are in the northern part of Nigeria. This due to lack of generators in the Northern Nigerian. 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 STATCOM at Maduguri substation.
