History of Traction Power Control by Microprocessors

This paper presents the history of traction power control by microprocessors, from the first use of microprocessors to the current state of the industry. It also looks at where the industry appears to be headed, and makes a recommendation on where it should go in the future. It addresses fail-safe issues, failure modes, self diagnostics, redundancy, and reliability, and it will also address the question of whether or not we should have total traction power control by microprocessors. It discusses the advanced programming and communications capabilities of microprocessor-based relays, which can provide better ways, both locally and remotely, to monitor, control, diagnose, and maintain equipment in the substation, and weigh these against the desire of agencies to use only service-proven equipment. It also looks at long-term cost issues. These include the cost of future modifications, and the increased efficiency of substation maintenance through the use of automated reporting.
