DESCRIPTION:[Improving renewable grid reliability through precision measure
 ment]\n\nThis talk will provide an overview of novel research to underpin 
 the delivery of renewable energy. Some examples include:\n\n- New referenc
 e measurement systems for electrical power at frequencies up to 200 kHz\, 
 harmonics and flicker. Not only the amplitude of powerline harmonics but a
 lso their phase with respect to the fundamental can now be measured with a
 n uncertainty of 0.001 degrees\, traceable directly to the International S
 ystem of Units (SI) via quantum voltage standards based on the Josephson e
 ffect.\n- A reference system to calibrate Phasor Measurement Units (PMUs) 
 that measure a number of physical quantities\, including rate of change of
  frequency\, synchronised to Coordinated Universal Time (UTC) using timing
  signals that are derived from the Global Positioning System (GPS) and/or 
 other Global Navigation Satellite Systems. The new NMI facility provides c
 alibration of PMUs traceable to the Australian national standards of elect
 rical and time quantities.\n- State of the art reference systems for measu
 ring complex high voltage waveforms up to 100 kV and currents up to 4000 A
  in the frequency range up to 20 kHz.\n\nRapid development of sustainable 
 sources of energy and energy-efficient appliances comes with a challenge 
 – to ensure safe and reliable operation of electricity grids and equipme
 nt connected to them. Learn how precision measurement provides a foundatio
 n to quantify the risks associated with the variation in the powerline fre
 quency\, fast transients and degrading power quality caused by high-freque
 ncy harmonics\, flicker and voltage fluctuations. Become immersed in the f
 ascinating world of leading-edge electrical measurement science and techno
 logy.\n\nSpeaker(s): Dr Ilya Budovsky\, \n\nHarricks Auditorium\, Engineer
