PROT 409: Generation System Protection

PROT 409 provides an in-depth study of the principles and schemes for protecting generation systems. The course provides advanced guidelines for relay application and settings for generator protection relays, including stator and rotor fault protection and protection against other abnormal operation conditions. Additional topics include an overview of power system faults, synchronous generators and generator grounding methods, and generator fault calculations. Note: This course teaches fundamental knowledge but does not provide hands-on experience with SEL relays.

Audience

Engineers who need a comprehensive understanding of the design concepts and methods used in protecting electrical power generation systems should attend this course.
