HV / LV POWER SYSTEM RELAY PROTECTION
04 – 08 SEPTEMBER 2017, PAPUA NEW GUINEA
About The Course
This seminar is specifically designed to provide an advanced understanding of the principles of power system protection design. Yet, via a progressive “building block” approach, this seminar has been specifically designed to meet the learning requirements of those who presently have only a fundamental knowledge of protection principles, while also considering advanced topics to provide a valuable insight for those more experienced in the discipline of power system protection design. Hence, this seminar will assist both those whose day to day work involves them in the application of protection design, coordination and relay setting, and also those in less directly associated areas of electricity system design
- The introductory material covers the basic principles of protection design, reliability, security and dependability as well as the implementation of unit and non-unit protection schemes, and remote, local and dead zone back-up schemes.
- With this grounding, delegates learn the principles of fault level calculation, including a comprehensive, but easily comprehendible discussion of sequence components.
- The seminar proceeds to cover the application of over current and earth fault protection, including application to transformers, parallel networks, and the need for directional facilities.
- The implementation of voltage and current transformers, to IEC60044, covers both the steady state and transient requirements for these essential components, including the application of the (1+X/R) CT transient requirement.
- Distance relay protection discussions cover fundamental design aspects, relay comparator characteristics and load transfer implications. Protection signalling requirements, to meet regulatory requirements covers the fundamental principles of distance relay permissive and blocking schemes as well as considering power line carrier applications.
- Unit protection scheme discussions cover both the application of high impedance differential schemes and biased low impedance differential schemes. In considering the latter with the specific application to transformer protection, the aspect of phase angle correction, zero sequence current correction, CT connection and the application of microprocessor based relays is considered in detail. The special application of high and low impedance schemes to busbars is discussed. The application of unit protection to feeders covers the implementation of feeder current differential relays.
- Short circuit protection of induction motors is considered, but since most electrical failures are actually the result of previous overheat, this latter topic is especially considered in detail.
- Finally, the specialized requirements for the protection of synchronous generators are comprehensively considered. This discussion includes high speed protection for actual generator faults, and also coordinated slower protection philosophies for generator and power system events.
This seminar is specifically designed to provide a comprehensive and in-depth understanding of the principles of power system protection design. This seminar has been carefully formulated to provide a valuable insight into power system protection design and principles for those more experienced in the discipline of protection design while yet meeting the learning requirements of those who presently have a more limited knowledge of power system protection principles.
Who Should Attend
This seminar will assist both those whose day to day work involves them in the application of protection design, coordination and relay setting, and also those in other less directly associated areas of electrical power system design. This seminar has been prepared specifically to meet the requirements of:
- 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.
- Power System Network Operators, to ensure optimisation of network performance and operation without compromising protection principles or risking inadvertent protection operators.
- 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.
- Project Managers, to ensure that the project implementation provides a safe and efficient implementation of electrical design.

Course Faculty - 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.
