Hidden Failure in Protective Relays: Supervision and Control
… works passively in conjunction with the existing protective relaying system at a substation. During normal system operating conditions, the RSS supervises the relay system to prevent trips due to hidden failures. During wide area network disturbances, it adapts the relay system to increase …

Analyzing voltage sag direction using protective relays and deep-learning methods
… monitor. This thesis studies the applications of protective relaying and deep learning techniques in identifying the direction of voltage sags using the real-time waveforms of voltage and current to estimate whether the fault is upstream or downstream from the monitored location(s). The fault data …
