These power and control systems provide emergency/backup power needed to keep critical security equipment up and running in the event of a loss of utility feed. To ensure a continuous flow of power, PLC controls automatically start and stop prime movers, annunciate prime-mover status and alarms and control priority loads. Systems also include synchronizing switchgear and sensors to monitor pertinent data from generator sets and overall system. In addition to emergency power, system designs may include a variety of sophisticated control functions such as cogeneration, peak shaving, load curtailment and utility paralleling for both open-transition transfer and live-source, closed-transition transfer.
