The complexity of the modern electrical power systems is steadily increasing with the penetration of massive amount of asynchronously connected renewable generation. This generation that is connected through inverters reduces the inertia of the Grid and significantly changes how today's power system operates. These characteristics require shortened power system response time and strategies for dealing with the grid's reduced inertia and weakened system strengths. GE's advanced wide area monitoring protection and control (WAMPAC) solutions address these challenges and enable utilities to have a reliable, stable, and green power system. WAMPAC solutions address the challenges of connecting renewable resources by integrating distributed controls that respond in real time and by providing system operators with situational awareness needed to respond to power system disturbances. These WAMPAC solution provide cost-effective methods to improve resiliency, reliability, and security of integrated grids.

Key Benefits

• Enabling secure renewable integration in the Grid
• Fast & reliable actions based on wide area and accurate information ensuring grid stability
• Real time grid actions that are proportional to the size of the event

How WAMPAC solutions work:

• Utilize sensing and monitoring of power system characteristics at many points across the grid.
• Communicates measured characteristics with all distributed and centralized monitoring and control locations.
• Deploys distributed algorithms for enabling fast control to isolate and react to localized events.
• Provides enhanced visualization for real-time situational awareness.
