Description

This course covers basic protection concepts and applications. The main objective of this course is to give students an understanding of the technical aspects of power system protection and management. The concepts and operation theory of electromechanical and modern relays (electronic, digital, and IEDs) will be covered as well as proper protection to individual components such as distance, feeder, directional, transformer, busbar, motor and generator protections. The course also includes an overview of electromechanical and digital relays.

Objective

Power-system protection is a branch of electrical power engineering that deals with the protection of electrical power systems from faults through the isolation of faulted parts from the rest of the electrical network. The objective of a protection scheme is to keep the power system stable by isolating only the components that are under fault, whilst leaving as much of the network as possible still in operation.

Target Audience

Employees who require a general knowledge of, or refresh their knowledge in Protection Systems to fully understand how they interface with their equipment, but who do not work directly on the relays, eg: supervisors, electricians, technicians, technologists, P&C operators and area dispatchers.
 
Upon successful completion of this course, the participants will have reliably demonstrated the ability to:
  1. Understand general protection schemes used at a power generation station that differs from protection schemes used at a transmission substation or at a distribution substation.
  2. Explain the principles of protective relaying including the theory and operation of modern relays (electronic, digital, and Intelligent Electronic Devices (IEDs).
  3. Understand different relay systems and how they respond to a fault.
  4. Understand the applications of protection devices in the design of protection systems for transmission lines, feeders, transformers, busbars, motors and generators.
  5. Understand the operating principles of protection system components, e.g. fuses, relays, circuit breakers, instrument transformers and their applications for the design of protection systems for transmission lines, motors, generators and transformers.
  6. Indicate the most common elements used to protect the different elements of the power network system.
  7. Apply Current Transformers (CT) and Potential Transformers (PT) to relay systems.

Michael D. N. Dang obtained his B.Sc. (Hon.) in 1968, M.Sc. in 1969 and Ph.D. in 1972 all in Electrical Engineering from the University of Manchester Institute of Science & Technology, England. He worked for the Central Electricity Generating Board in London before immigrating to Montreal in 1981 and joining Shawnigan Consultants Inc. He came to Toronto and joined Ontario Hydro/Hydro One Networks Inc. in 1988. He retired from Hydro One in June 2013 and joined Mohawk College of Applied Arts and Technology where he managed the R&D programs and projects including lecturing in Power Quality at McMaster University and Power System Protection and Power System Analysis at Mohawk College His major study areas include power system protection, harmonics, power system analyses, system operations and connections of combined-cycle and wind-turbine generation to the Grid. He has published 17 technical papers to date.
Dr. Dang is a registered professional engineer in the Province of Ontario, a Fellow of Engineers Canada in 2010, and a member of the Experience Requirement Committee of Professional Engineers Ontario.
