Power quality is the study of deviations from nominal in supply voltage waveform. A power system has far too many connection points to allow for comprehensive monitoring. Instead, the overall state of power quality has to be estimated from a carefully selected sample of sites. Benchmarking takes this one step further by recording the behaviour of several utility networks simultaneously and comparing results. This gives useful feedback on how different utility PQ management practice compare and what aspects need improvement. Much work has been done at University of Wollongong over the last twenty years on benchmarking for Australian distribution systems and this is now being extended to transmission networks. Issues include finding suitable measurement sites, the use of different standards in different Australian states and summarising an extremely large volume of data to give useful high level insights. The talk will be oriented to a general audience.
