Advanced Quality of Electrical Supply - presented by APQRC (UOW)

The rapidly increasing installation of electronic equipment such as digital controls, computers and sensitive process control equipment has increased the susceptibility of utility customers to supply disturbances. In addition, the application of power electronic equipment such as variable speed drives and renewable energy systems has in turn often increased the level of disturbances that may impact operation of
customer equipment. Electricity supply businesses need to have an ongoing awareness of problems and solutions in the power quality area. This course is an advanced course which builds on the Introductory Quality of Electrical Supply course and is designed to expand the coverage of selected power quality topics
in order to give participants practical skills in the analysis and mitigation of specific problems. The selected topics for this course are harmonics, voltage unbalance, voltage sags and interruptions, power electronic mitigation techniques, power quality monitoring and reporting.


COURSE BENEFITS

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.
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.
