Predictive Analytic to Supervise Zone 1 of Distance Relay Using Synchrophasors

Distance relays are the workhorses of transmissi-online protection systems. But those close to the electrical center will pickup even during transient instability. To identify them, we introduce a new coordinate system with normalized minimum magnitude of positive-sequence voltage on the line (V(min...
