The Australian Power Quality & Reliability Centre (APQRC) at the University of Wollongong, Australia, is a nationally and internationally recognised centre of excellence which supports research, education and consulting in distribution and transmission system power quality, reliability and renewable energy systems.

The Power Quality & Reliability Centre was established in 1996 through a joint agreement between the University of Wollongong and Integral Energy. Since then industry has continued to support the Power Quality & Reliability Centre contributing more than $4 million of sponsorship funds.

The focus of the APQRC is to work in conjunction with industry to improve the quality and reliability of electricity supply for the benefit of all consumers. This focus is achieved through education (undergraduate, postgraduate and continuing), research and consulting activities. APQRC staff are active on a number of peak industry bodies and standards organisations. These include Standards Australia, IEC (International Electrotechnical Commission) and CIGRE (International Council on Large Electric Systems) working groups and the Energy Network Association (ENA).

Training

The APQRC runs regular training courses. These courses include:

  • Technically detailed courses in the areas of power quality, reliability, energy efficiency and renewable energy for professional engineers and technical staff.
  • Awareness courses for senior management.
  • Review courses for engineering managers.

Upcoming courses are:

Applied Power Quality: Harmonics, Unbalance & Voltage Sags

Participants will learn advanced analysis techniques and methods of improving power quality by both network and plant modifications. Course participants will have the opportunity to develop their knowledge and skills through discussion and laboratory sessions.

12-13 July 2018, University of Wollongong

Applied Power Quality: Harmonics, Unbalance & Voltage Sags

Following the course, participants will be able to:

  • Calculate distortion levels, evaluate resonance problems, apply the AS/NZS 61000.3.6 Technical Report methodologies and assess the effectiveness of mitigation methods.
  • Apply symmetrical component theory to the calculation of unbalance factors, understand the effects of unbalance on various loads and appreciate the essentials of voltage unbalance standards.
  • Determine sag depth at a site depending on fault location or motor start characteristics.
  • Assess options for sag mitigation and determine whether they should be applied within the plant or network.
  • Understand how power electronic devices can be used to mitigate power quality problems.
  • Better understand PQ monitoring methodology including disturbances to be measured, how they should be characterised and reported, and their acceptable levels.

Who should attend?

Uutility specialists, consultants, engineers and senior technical staff who wish to advise customers on power quality concerns, or who service large customers or who wish to understand aspects of network design, construction and maintenance techniques for maximising quality of supply.
The course assumes the participants will have an understanding of phasor calculations, simultaneous equations and Fourier analysis.

Examples of other courses available are:

The Master of Electrical Power Engineering course is an industry recognised postgraduate qualification providing advanced power engineering knowledge delivered by industry experts to engineering graduates working in the industry. The course can also be undertaken as a Graduate Certificate in Electrical Power Engineering. See also the UOW Course Handbook for additional information on the masters course, or the graduate certificate course. To join the course Apply Online.

Workshops on Australian and International Standards are also available. Arrangements can be made to have the above courses or specially tailored courses on various aspects of power engineering delivered at your business (minimum numbers apply).
