An Introduction and Review of Practical Synchrophasor Applications for Substation Equipment Analysis

摘要

Synchrophasor data and its applications are moving out of the realm of research and wide area transmission grid visibility and into mainstream utility operations for substation equipment performance analysis. This article introduces synchronized phasor measurements as a concept and then presents a literature review of utility applications such as identifying loose connections, failing equipment, and a straightforward method for determining substation phasing. As utilities continue to add equipment that supports sending and archiving phasor measurement unit (PMU) data, the leveraging of this data can potentially save time, money, and prevent unplanned equipment outages.
