Maintenance optimization of high voltage substation model

Abstract

The real system from practice is selected for optimization purpose in this paper. We describe the real scheme of a high voltage (HV) substation in different work states. Model scheme of the HV substation 22 kV is demonstrated within the paper. The scheme serves as input model scheme for the maintenance optimization. The input reliability and cost parameters of all components are given: the preventive and corrective maintenance costs, the actual maintenance period (being optimized), the failure rate and mean time to repair - MTTR.
