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.
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.
SEL also provides automation services for substations and distribution networks. Our automation solutions leverage the built-in capabilities of our protective relays and our Real-Time Automation Controller (RTAC) control libraries to provide scalable, modular automation systems.SEL Automation Services More About SEL Distribution Automation
