ELEX 8285 - Power System Protection

Electrical and Computer Engineering Part-time Studies Course

School of Energy

BCIT is planning for a substantial return to on-campus activity for the fall 2021 term as informed by BC Public Health Officer guidelines. Refer to each course listing for details.

Course Details

This course describes design methods and equipment required to protect utility power systems against faults and operating conditions that could damage power system components. Topics include a review of power system fundamentals, types of faults, and protection philosophy. Design strategies for protection of distribution feeders, substation buses, transformers, transmission lines, and generators will be specified in detail. Laboratory exercises based on power system modelling for fault studies, protection coordination and fault record analysis are included in this course.

Learning Outcomes

Upon successful completion of the course, the student will be able to:

  • Describe the economic, reliability and safety roles that protection systems have in power system operation.
  • Specify how faults on power systems occur, and the impact these faults have on power system equipment and operation.
  • Analyse electrical one line diagrams and determine suitable protection schemes to allow safe and reliable operation of power systems.
  • Analyse how the non-ideal operating characteristics of instrument transformers impact protection system operation.
  • Design using a philosophy which considers the entire life cycle of protection system equipment, from initial design, installation, and commissioning to long term maintenance and performance monitoring.
  • Describe the operating principals of overcurrent, impedance, and current differential fault detection methods.
  • Identify power system faults using symmetrical components.
  • Design protection schemes for power system generators, transmission lines, transformers, buses, and distribution systems.
  • Design fault and protection coordination studies using modern power system simulation software.
  • Analyse the impact emerging technologies on traditional protection schemes

Effective as of Spring/Summer 2013
