West Africa Power Pool Transmission Line Monitoring Using the Scada System

The SCADA systems introduced in this study monitor the entire length of a 225 kV transmission line at 1,304 km for power disturbances caused by physical contact with conductors, which may distort the power flow. This novel approach to long transmission lines in this study has led to significant changes in the power systems in the region. Furthermore, the significance of this study on the West African Power Pool, especially for the CLSG transmission line of 225 kV in Sierra Leone and other countries served by the CLSG transmission line, is that it is impactful and has considerably improved electricity accessibility and availability in the region. Furthermore, rural electrification has substantially increased by connecting 99 towns and villages, and additional communities will be connected in the future by shield wires with 225 kV, addressing the lack of access to electricity in these areas, which can be easily monitored by using the SCADA system. This development has led to a notable increase in socioeconomic activities due to the increased energy availability in these areas. A SCADA has a better data management system, managing ICSs for data acquisition, communication, information sharing, and processing across the entire span of the transmission line ($1,304 \mathrm{~km}$), including substations. This approach enables the isolation of faulty areas through SCADA systems, unlike its counterpart, DCS, which is limited. The implemented SCADA for the CLSG transmission line in this study operates in frequency mode for power stabilization.
