Grid Stability and Wide-Area Monitoring
Maintain grid stability and enhance situational awareness with advanced wide-area protection, monitoring, and control systems.
Renewable generation is introducing complex power system dynamics. Increasing demand is pushing transmission systems closer to their design limits. And reliability expectations continue to increase. Now more than ever, transmission system owners need to be equipped with system insights that support effective control decisions.
Improve Transmission System Protection and Stability
Ensure transmission system stability with a special protection scheme (SPS) or remedial action scheme (RAS) designed, tested, and commissioned by SEL. Our powerMAX power management and control solutions include wide-area monitoring and control systems, and are trusted by utilities for integration of large wind power stations.
SEL uses advanced modeling and simulation, informed by decades of power engineering experience, to analyze system requirements, validate designs, and optimize the performance of the system.
In some cases, utilities can operate transmission corridors at a significantly higher capacity after the RAS/SPS is implemented, increasing revenue and freeing up capital expenditure.
Wide-Area Situational Awareness
Enhance system visibility, monitoring, and control with next-generation wide-area monitoring software (WAMS) and wide-area situational awareness (WASA) solutions.
SEL Synchrowave Operations software complements SCADA and energy management systems (EMSs) by turning high-resolution time-series data—including synchrophasor data, relay event reports, point-on-wave data, and GIS geospatial data—into actionable system insights that support better decision-making.
A Partner for Any Modernization Project
SEL offers modernization solutions and services for any part of the grid, scaled to your needs. Partner with us on individual projects or multi-year modernization programs.
We design electric power systems, coordinate procurement and construction, manufacture the relays, build the panels, and install and commission the protection and control systems.
