Application of Australian Standards for Management of Harmonics, Unbalance & Flicker

A course on the application of Australian standards for allocation of harmonic, flicker and unbalance emission levels, presented by the Australian Power Quality and Reliability Centre.

Course Dates: 2-3 November, 2022

Course Description

Before connection of large loads or generators, the National Electricity Rules (NER) require actions to be taken to ensure that the connections will not have an adverse impact on network quality of supply which essentially include the disturbances: harmonics, voltage fluctuations and flicker and voltage unbalance.

It is the responsibility of the network operator to allocate an agreed level of disturbance emission level and it is the responsibility of the connection proponent to ensure that the installation to be connected can meet the emission requirements. In Australia, the most common processes used to specify emission allocation levels are defined in the AS/NZS 61000 series of EMC standards, specifically:

  • AS/NZS TR IEC 61000.3.6 for harmonics
  • AS/NZS TR IEC 61000.3.7 for voltage fluctuations and flicker
  • AS/NZS TR IEC 61000.3.13 for unbalance

This course has been developed to allow better understanding of these standards and their methodologies for allocation of the specific disturbance emission levels.

Course program

Day 1

Day 1 of the course will focus on the following:

  • The role of standards and the various categories of documents produced by standardisation bodies
  • Voltage unbalance: analysis principles, standards and management
  • Harmonics: calculation principles and the role of standards as regards limits, determination of customer emission allocations and compliance assessment

Day 2

Day 2 of the course will focus on the following:

  • Harmonics (continues)
  • Voltage fluctuations and flicker: analysis principles standards and management
  • Case studies illustrating emission determination and analysis for renewable energy generators
  • Discussion session

Course Outcomes

At the conclusion of the course participants will:

  • Have an understanding of the causes and effects of harmonic distortion, voltage fluctuations and flicker and unbalance and the need to limit their magnitudes in electricity supply networks
  • Have an understanding of the current Australian Standards related to power quality and how they work together to maintain acceptable quality of supply
  • Understand the challenges in applying the Australian Standards for allocation of harmonics, voltage fluctuations and flicker and unbalance
  • Have encountered the problems in the practical application, concepts and methodologies defined in AS/NZS TR IEC 61000.3.6, AS/NZS TR IEC 61000.3.7 and AS/NZS TR IEC 61000.3.13

Who should attend?

This course has been designed to assist those who deal with the allocation of power quality emission levels. The course would be of particular interest to engineers or technical officers working with network service providers or proponents of large loads or generators, particularly renewable energy generators such as solar farms.

Speakers

Researcher, Australian Power Quality & Reliability Centre
University of Wollongong

Mr Jason David is a researcher with the Australian Power Quality and Reliability Centre, with a focus on the impact of renewable energy generation connections. His latest research involves reviewing Australian and international harmonic standards and their applicability to systems with high penetration of renewable energy generation. He also has extensive experience in harmonic modelling and compliance assessment within the Australian context.

Emeritus Professor Vic Gosbell has many years experience in the electric power supply industry, having worked on power system stability, power electronics and variable speed drives and power quality. He set up the Power Quality Centre in 1996 and was its Technical Director for nine years. Although now retired, he still contributes to the work of the Centre, particularly in the areas of harmonic management and the development of power quality survey and reporting techniques. Vic is an active member of the Standards Australia technical committee EL-034 (Power Quality).

Professor, School of Electrical, Computer and Telecommunications Engineering
University of Wollongong

Professor Sarath Perera was the Technical Director of the Australian Power Quality and Reliability Centre for the last 15 years. He is also a Professor in the School of Electrical, Computer and Telecommunications Engineering. Professor Perera has over 40 years’ experience in the areas of power quality, distribution system reliability, EMC and power system simulation techniques. He is the Chair of Standards Australia technical committee EL-034 'Power Quality'.
