Testing synchrophasor data quality for applicability to transmission optimisation

This paper summarises a testing exercise carried out by a utility, a Phasor Measurement Unit (PMU) manufacturer and a developer of systems and applications to qualify the PMU for use in applications of interest for transmission system security and optimisation.

The testing goes beyond the IEEE standard requirements for synchrophasor measurement in terms of both the static and dynamic requirements. It was proven that the PMU met the requirements for the applications considered. The features tested characterise the time-domain and frequency domain performance and can be applied to other application areas.
