In this study, a methodology is proposed for the reliability evaluation of traction power substations for mass rapid transit in order to calculate the reliability index. The technique for calculating failure rate, mean time to failure, mean time to repair, availability, and unavailability is the Reliability Block Diagram. This method is utilized in the process of determining the reliability index. Utilize the reliability index to determine the capacity outage probability table, loss of load probability, and loss of load expectation for each traction substation. This will allow to determine the estimated number of days per year that the substation will be unable to satisfy its demand load. The component reliability data of the traction power substation have been taken from previous research published in the relevant field. This research is solely focusing on the distribution substations that connect to the DC traction substations; it does not take service substations into consideration. Evaluation of the dependability of a traction power substation was carried out for a genuine system in Bangkok, Thailand, known as the MRT Purple line. When measured against the BAL-502-RF-03 standard developed by the North American Electric Reliability Corporation, the outcomes meet the criteria for acceptance.
