Remedial Action Schemes

SEL designs remedial action schemes, or special protection schemes, to detect abnormal conditions in your power system and take automatic corrective actions. The intent of these schemes is to protect against blackouts and system instability, increase corridor capacity limits, and provide the ability to operate your system closer to its stability limits. The SEL solution integrates new and existing devices, consolidates information from multiple locations, and performs control actions via dedicated Mirrored Bits^® communications channels up to 80 km. Alternatively, IEC 61850 GOOSE messages cannprovide control over Ethernet.

Autosynchronization Systems

SEL Autosynchronization Systems measure voltage and frequency of both the generator and the utility system, send proportional correction pulses to adjust the governor and exciter as necessary, and automatically close the breaker on synchronization. This process enables safe, secure, unattended synchronization of generation onto the power system.

The base system includes an SEL-451-4 Bay Control, Automation, and Protection System with installed settings for autosynchronization. The system software selects synchronization voltage sources from six independent single-phase inputs, eliminating the need for complicated synchronization switches and manually selected voltages.
