PROT 413: Generation Station Protection

Description

PROT 407
Course Information

This is a four and 1/2 day course.

Course Base Fees: $3,000 USD

PROT 413 is a fundamentals course that provides both a theoretical and applied (or practical) introduction to protection of generators, large transformers, and auxiliary power systems and equipment at power stations. In this 4.5-day course, students will complete exercises to help them learn symmetrical components and concepts of protection for generators, motors, transformers, and buses.

Audience

Electrical engineers who are responsible for the protection systems of generators, large transformers, and the auxiliary power systems that support power stations, including nuclear power stations, should attend this course.

  • Explore power station arrangements and methods for generator grounding.
  • Review symmetrical components concepts applied to unbalanced fault analysis.
  • Review protection fundamentals, such as primary and backup protection concepts, description of protection system elements, and digital relay architecture.
  • Review current and voltage transformers and their impact on protection scheme performance.
  • Discuss common power system protection issues at power stations.
  • Review generator stator phase and ground fault protection schemes.
  • Review generator rotor ground fault protection schemes.
  • Review generator abnormal operation protection schemes, including, but not limited to, thermal, current unbalance, loss of excitation, out of step, and overexcitation.
  • Discuss bus protection concepts and analyze bus protection schemes.
  • Discuss transformer protection challenges, concepts, and schemes.
  • Review motor thermal and short-circuit protection principles.
  • Review protection schemes applied to power station auxiliary systems.
