Abstract

Optimum maintenance scheduling for traction substations guarantees reliable and efficient operation of electrical railways. Reliability-based optimum scheduling models are respectively proposed through the analysis of the structure and maintenance cost of individual components in traction substations in this study. An individual components-based heuristic algorithm for solving the proposed models is developed considering the structural complexity of traction substations. Furthermore, a reliability evaluation-based co-ordination method is devised for optimum scheduling of traction substations. Case studies from field data are implemented to verify the validity and practicability of the proposed methods by their solutions.
