Abstract

Phasor Measurement units (PMU´s) are becoming standard equipment in electrical grids around the world. They are capable of generating a significant amount of data on a continuous basis from distribution and transmission networks. Several months of data from 2 PMU´s situated on a distribution network were captured in raw format. This data was separated by measurement type and compressed using a number of standard compression algorithms. The results show the compressibility of PMU data for these algorithms and are used to estimate the space requirements for storing a day of data from a single PMU.
