Transdyn Selected to Provide Substation Automation System for MARTA Ashby Street Motor Control Center
January 21, 2010 -- As part of MARTA’s (Metropolitan Atlanta Rapid Transit Authority) innovative approach to modernizing stations, traction power substations, and other facilities, Transdyn was awarded a contract by MARTA to provide an automation system for the Ashby Street Motor Control Center.
MARTA monitors and controls 48 miles of transit mainline track via an extensive network of power substations. Traction power equipment is distributed over substations consisting of AC/DC substations, gap breaker houses, ventilation fans and other related equipment.
Transdyn is designing and developing a PLC based control system that allows control, monitoring, and maintenance functions of the Ashby Street motor control center, ventilation, fans, and dampers. The new PLC system interfaces with the existing DYNAC® SCADA system and an RTU. Various operational sequences are being developed to run in emergency situations.
A local operator interface is being developed to provide operations personnel with monitoring, control, and alarming capabilities.
Under a previous contract, Transdyn provided MARTA an automation system for the first substation to be upgraded as part of the transit system modernizing initiative. Transdyn delivered a new PLC control system tied into a DYNAC based SCADA system that includes specialized diagnostic functions suited to meet the needs of the maintenance department.
MARTA has been serving the metro area for 30 years. As the 9th largest transit system in the nation, MARTA provides rail and bus transportation to a daily average of 500,000 passengers via heavy rail and rail stations.
