Real Time Operation of Synchrophasor Data Functions in Transmission System Control Room

Rare events and disturbances in transmission network can occur in some time frames or with some electrical values which are not fully covered with relay protection and SCADA systems. This gap can be fixed with Wide area monitoring system in control room. WAM system collects synchrophasor data from all 400 and 220 kV transmission lines. Inside WAM system special functions, based on synchrophasor data, were developed for these purposes. That way total monitoring for power oscillations in transmission network is established. These functions are in testing phase and will be connected to SCADA system in control room. New generations of Phasor measurement units send to control room values for all three phase values and positive, negative and zero components. Function for early warning also was developed based on negative and zero components. Special attention was put on communication channels and delay aspects. Special algorithms were implemented to override those aspects in communication channels. Few examples for those new functions will be elaborated and presented.
