Russelectric power control systems with dual PLC controls
By Alyssa Dalton
April 5, 2013 – All Russelectric on-site power control systems are equipped with dual PLC controls for automatic generator set starting and stopping, status and alarm annunciation, synchronizing, and priority load control. A primary PLC controls system operation with a backup PLC running the same program as the primary, so if the primary PLC fails, the backup PLC assumes operational control. If both PLCs were to fail, a manual control system allows operating personnel to synchronize and parallel the generators onto the bus, as well as to add and shed load. LCD touchscreen operator interface is included. Custom system integrating SCADA and simulation are available as options. All systems are UL listed and are designed and built in accordance with ANSI, IEEE, and NEMA standards.
