openPG

Description

openPG administered by the Grid Protection Alliance (GPA) is a synchrophasor data gateway. The openPG is purpose built as an edge device for an electric utility's security perimeter. It has been developed using the proven time-series framework architecture incorporated in GPA's openPDC. The openPG creates a security buffer between critical internal infrastructure and external systems to protect reliability and market sensitive data. The openPG also reduces the cost of phasor data exchange through ease-of-configuration. The openPG implements a true publish-subscribe architecture where the sending gatgeway owner authorizes phasor data points as available for subscription by specific consuming gateways. Once authorized, the consuming gateway automatically discovers the phasor measurements that have been made available to it by other openPGs and allows the selective subscription to these measurement points. The openPG can receive multiple input data streams and forward this phasor data to the specified gateways without the need for a phasor data concentrator (PDC) and their associated data concentration delays.
