Real-time synchrophasor based measurement and monitoring

Wide Area Management System (WAMS)

Managing power system stability and responding to system disturbances

Power systems are experiencing fundamental change in the way they are managed, driven by the changing energy landscape and growing demand for electricity. Increasing volumes of renewables coupled with reducing inertia and more sensitive voltage profiles are creating more complex issues for system operators.


WAMS provides visibility that is based on real-time data streamed from Phasor Measurement Units (PMU). A host of WAMS software applications use this data to provide context-specific information, presented through an intuitive user interface. GE’s WAMS solution complements traditional SCADA-based energy management to deliver fast and proactive grid stability management to meet the complex challenges of modern power systems.

Mitigate risks of major disturbance and blackout through enhanced monitoring and control

Reduce time spent in emergency operational states with accelerated resynchronization and balancing

Improved dynamic monitoring based on PMU data

Supports synchrophasor-based protection and control and tuning of generator and load dynamic performance

2021 IEEE NASPI Oscillation Source Location Contest Winner

GE Digital wins WAMS award for real-tool application to manage grid oscillations

GE Digital tied for first place with Rensselaer Polytechnic Institute in the global 2021 IEEE NASPI Oscillation Source Location Contest involving vendors, utilities, research centers and universities.


GE WAMS solutions and its Oscillatory Stability Management application is a fundamental real-tool application to manage grid oscillations like the January 11, 2019 Eastern Interconnection Forced Oscillation Event. Many observed oscillations are not detected in traditional model-based studies. They can quickly grow across the grid, leading to constraints or even outages. Being able to quickly locate where oscillations are being originated, can help operators to mitigate them and ensure secure grid operation.


As recommended by NERC: RCs should have real-time oscillation detection tools in place to identify when oscillations are occurring, determine if it is limited locally within their footprint or across a wider area, and distinguish between forced oscillations and poorly damped natural system modes. GE Digital WAMS is fully prepared to meet NERC requirements.
