SCADAStreamlined Access to All System Data Interactive, simple to use operator interfaces for
monitoring and control
Sequence of event (SOE) analysis software provides a 1ms time-tagged history of all critical events
Event report analysis software provides oscillography reports (digital fault records) of critical protection-level events.
Settings management software manages all settings for all devices in the system – from one location!

SEL- VCS Functionality Controls many devices to optimally share total
MVAR load Capacitor banks, LTCs, generator field exciters
Large synchronous motor exciters, STATCOMs, SVCs
Improves system stability during disturbances Keeps active MVAR-producing devices off limit
Allows them to reject system disturbances
System interties (MVAR) and bus voltages are kept at set point
Distributes MVARs between units
