Power management solutions provide energy assurance with reliable, resilient, and secure solutions for maintaining uninterrupted energy delivery. SEL solutions maintain system stability with deterministic control that operates at subcycle speeds to preserve the load and generation balance while seamlessly islanding and recoupling with the bulk electric system.
An SEL powerMAX Power Management and Control System is an integrated system composed of scalable relay and control hardware, software, and logic processing and designed by Engineering Services experts.
By operating at relay speeds, SEL deterministic controllers can reliably balance load with the available generation for seamless islanding and resynchronizing, so processes stay online.
SEL computers are built for speed, reliability, and uptime. SEL uses the same high standards for computers, from design to manufacturing, that they do for protective relays. The computers are made in the U.S.A. to ensure quality and security.
These devices enable fast islanding detection and protection, monitoring, and control for distributed energy resource (DER) interconnections.
