Simulation and analysis of assessment procedures for condition based maintenance of MV/LV substations

摘要

The application of condition based maintenance can reduce maintenance costs while maintaining a high standard of reliability because equipment is maintained only when the condition implies urgency. Commonly the equipment's condition is rated by subjective choice of maintenance personnel. An optimal maintenance planning needs objective condition assessment methods. In this paper, the parameterisation of two different assessment methods for MV/LV substations is introduced. These methods are applied in an asset simulation for condition based maintenance to analyse their influence on maintenance costs and failures. The simulation shows the influence of the assessment methods on failures and costs at different maintenance planning strategies.
