Load Shedding - Phase II & III: Concept Development and Prototype Design for Passenger Rail Equipment
An investigation occurred by Sharma & Associates, Inc. (SA) of the feasibility of temporarily shedding electrical demand associated with passenger car heating ventilation and air conditioning (HVAC) systems during periods of peak traction demand, with the goal of right-sizing the main engine on a passenger locomotive. Architecture of a concept to monitor the load shedding demand at the locomotive was developed. The necessary MODBUS remote terminal unit (RTU) components for the communication and control were identified, procured and tested in the laboratory to confirm the functionality of the concept. Prototyping and field testing of the concept is recommended.
