Components importance analysis of PLC networks for the power holding company of Nigeria
Abstract
This paper has analysed the reliability importance of power line communication (PLC) system connected to the Nigerian national electricity grid for a period of eleven (11) years. Bimbaum's component importance technique is used to derive the components' reliability, importance functions of phase-to-earth, phaseto- phase and inter-system PLC couplings. A comparative analysis is made on the oomponents' reliability importance of the existing PLC system in the power Holding Company of Nigeria (PHCN), phase-to-phase and inter-system networks. The study has shown that the components' importance of PLC systems is a function of the coupling methods. The outputs of the analysis are then compared, with suggestions and recommendations made.
