Wide-Area Situational Awareness

SEL wide-area situational awareness (WASA) systems provide operators and engineers the right information at the right time for efficient operation and analysis of the power system.

In 2002, SEL began incorporating synchrophasor technology into protective relays at no charge because of the belief that synchrophasors would become a critical component of the protection, control, and monitoring of the power system. Since then, SEL has continued to innovate, develop, and deploy synchrophasor applications around the world. Learn how a U.S. utility worked with SEL to develop advanced WASA software that leverages synchrophasors and other high-resolution data.

Real-Time Monitoring
Improve visibility and understanding of the power system with time-synchronized power system measurements. Understand system stress by viewing power flows and angle differences across your entire system, and detect transient behavior that is not detected with traditional SCADA systems.

Power System Model Validation
Record the system response of generator trips, load shedding, remedial action scheme (RAS) operations, or other events. Analyze the archived system responses, and compare them to power system models. Simply export system response data to external power system simulation/modeling applications.

Disturbance Monitoring
Analyze archived synchrophasor data and relay event reports together in one display for a complete disturbance monitoring solution. Easily find system disturbances and export data to CSV and COMTRADE data formats for PRC-002-2 compliance.

Renewable Energy Monitoring
Understand how the increasing amount of renewable energy being added to your grid impacts system stability, and detect new oscillatory modes that may be inadvertently introduced. System dynamics from these generation sources change quickly—too fast to see at traditional SCADA rates. Use high-resolution displays for detection and tracking of the impact of renewables on your system.
