MICROGRIDS AND POWER MANAGEMENT

Remedial Action Schemes

Mitigate blackouts and function more efficiently than ever before.

The SEL powerMAX Power Management and Control System for utilities uses a remedial action scheme (RAS) in a control system capable of integrating large geographic regions of interconnected generation sources, transmission lines, and loads.

Every powerMAX RAS is as unique as the utility grid it protects.

We conduct system studies and modeling to understand your current situation and find the best possible way to achieve your desired outcome. We can also integrate a powerMAX RAS with your existing relays, meters, and communications systems to leverage existing hardware while reducing overall project costs.

Key Applications:

  • Monitoring, control, and integration of renewables and distributed energy resources (DERs)
  • Integrating large renewable sources, such as wind power stations and PV arrays, with transmission systems
  • Wide-area systems communications
  • Wide-area volt/VAR control
  • Synchrophasor monitoring and control
  • Fast decoupling solutions
  • Relay-speed operation across wide areas
  • Distributed computing and communications for smart transmission grid management

The Economy of Reliability and Efficiency

With the reliable control offered by SEL powerMAX systems, electric power providers and their customers reap economic rewards.

A powerMAX RAS allows bulk power grids to function closer to stability limits, operating transmission corridors at a higher capacity than ever before. In some cases, they can transmit over 50 percent more power across existing transmission lines.

The increase in efficiency allows you to meet rising demand without building costly new lines.
