PROTECTION OF HV & EHV TRANSMISSION SYSTEMS

22 – 25 AUGUST 2016, KUALA LUMPUR, MALAYSIA

About The Course

With specific reference to High Voltage (HV) and Extra High Voltage (EHV) electricity transmission systems, this 4 day seminar is designed to provide the delegates with a comprehensive understanding of the philosophy of protection scheme selection, protection scheme configuration, and the non-relay specific principles associated with the determination of scheme and relay settings.

Protection of today’s sophisticated Electricity Generation, Transmission and Distribution Systems is necessary to maximise safety for the public and electricity industry employees alike, to disconnect faulted plant from the system, and to maintain quality of supply to customers. Reliability of these protection schemes is important to ensure damage to the power system is minimised, faulted plant is disconnected, system stability is maintained, security is optimised, and to ensure unfaulted plant is not inadvertently tripped from service.

Especially with respect to HV & EHV electricity transmission systems, the modern trend is for these networks to be operated closer and closer to their limits of performance. This requires the associated protection systems to be optimized: to be simultaneously coordinated, to be fast operating, to be secure and to be reliable. These are conflicting requirements, but nevertheless their implementation is critical to the optimal performance of national and international electricity systems. In addition the protection systems associated with HV & EHV Transmission Networks must maintain power system stability while not constraining inter or intra-regional power flows.

This seminar, “Protection of HV & EHV Transmission Systems”, provides a comprehensive understanding of the sophisticated protection systems used to protect HV & EHV transmission and distribution systems. The seminar also covers the application of modern micro-processor based relay technology, as well as covering the application of older electronic and electromechanical relays, this latter group being the majority of devices still in service.

“Protection of HV & EHV Transmission Systems” is designed to provide attendees with an advanced understanding of the full range of protection equipment, including differential and distance protection schemes.

Learning Outcomes

On completion of this seminar you will be able to:

  1. Describe the principles, specify the functionality and determine the high-level (i.e. non-relay specific) protection schemes and settings associated with transmission and distribution power system plant, including high voltage busbars, transformers and feeders (differential protection).
  1. Specify a current transformer (CT) to cope with fault currents that include exponentially decaying transient DC components.
  2. Describe and explain the implications of voltage transformer (VT) transient performance.
  1. Design and implement distance relay protection schemes, in particular:
  • Select a suitable relay characteristic based on an understanding of relay comparator operation.
  • Allow for various starter characteristics.
  • Develop a grading plan to ensure coordination with protection relays elsewhere on the power system.
  • Allow for the effects of mutual coupling with other feeders on the same easement.
  • Design protection schemes and set relays for teed feeder configurations.
  • Design protection schemes and set relays for bridged feeder configurations.
  • Allow for the effects of arc and/or fault resistance.
  • Describe and explain the application of VT supervision, healthy phase polarizing, Switch OnTo Fault (SOTF) logic, power swing blocking logic, ensure load encroachment does not cause inadvertent tripping and ensure healthy phase fault currents do not degrade distance relay performance.
  1. Specify and explain the application of distance relay protection signalling schemes.

Who Should Attend

This seminar has been prepared specifically to provide this crucial knowledge for:

  • Planning Engineers, to identify the difficulties in providing protection for various power system configurations under review
  • Maintenance Engineers, to ensure that system protection is not compromised as plant is removed from service during maintenance
  • Circuitry Design Engineers, to ensure that protective schemes are implemented in a manner to provide optimum performance
  • Commissioning Engineers, to ensure the actual field installation of the protection scheme and associated relay settings meets the design requirements.
  • Field Technicians, to understand the importance of their role in installing, testing and maintaining effective, reliable, dependable and secure protection systems.
  • Protection Design Engineers, to identify protection implications and to ensure design, coordination and relay setting principles provide the necessary levels of speed, security, dependability and safety.

Barrie Moor

With over 39 years experience in the Queensland electricity supply industry, our principal engineer, the seminar author and presenter, Barrie Moor, has been involved in the design, coordination and implementation of protection schemes associated with Queensland’s HV and EHV transmission systems since 1981. Barrie also has extensive experience with the protection of large generating plants having had responsibility for the protection of generators at many of Queensland’s major power stations. From 2000 to 2007, Barrie filled the role of Senior Engineer Protection Design, with statewide responsibility, leading Powerlink’s Protection Design Team. From 2007 to 2012, in the role of Principal Consultant Substation Protection, and then Principal Engineer Investigations, Barrie provided specialist Protection Design and Fault Analysis services to support the Asset Management and Operational Groups within Powerlink. Barrie has 20 years experience within Australia and internationally (New Zealand, Singapore, Malaysia, Thailand, Pakistan, UAE, Ghana) in the provision of university post graduate training on the design and implementation of HV and EHV Transmission Protection Systems and also and Power Station Generator Protection Systems. Barrie has presented a number of papers on various specialised aspects of protection design at conferences both within Australia and internationally. Barrie represented Powerlink on CIGRE committee APB5, Power System Protection and Automation, and served as a corresponding member on Cigre and IEE working groups on Protection Systems.

LinkedIn Testimonials

  • I have now completed a couple of seminars / courses (Fundamentals of Power System Protection and Distance Protection training at QUT) with Barrie and once again could not ask for more. Barrie is an expert in Power Systems Protection and spares no effort to pass on his knowledge, striving to share his extensive knowledge in the topics at hand, Barrie impresses all. I will not hesitate to take another training course lectured by Barrie. I look forward to the next opportunity in power systems protection run by Barrie Moor.
  • Barrie is the best protection engineer I have had the pleasure to work with… They do not make protection experts like Barrie anymore…
  • Having worked with Barrie on numerous projects and whilst standardising Control Systems interface designs to protection schemes and plant, as well as experiencing Barrie’s protection systems and schemes training, I can readily attest that Barrie is an authority in the field of protection. His knowledge across all levels of protection (systems, design, theory) and ability to communicate (design, training) are astounding. Credit well deserved.
