Reliable power module for improved substation device availability

摘要

Disclosed herein are systems for maintaining protection of electric power delivery systems in the event of a control power failure or other anomaly. A reliable power module conditions electric power from multiple independent sources and provides electrical operational power to electric power delivery system protective loads. The reliable power module includes a power storage device for providing operational power even upon loss of all control power sources. The power storage may be sufficient to ride through expected losses such as a time to start up backup generation. The power storage may be sufficient to power a trip coil. Thus, electric power system protection is maintained even upon loss of control power.
