Geo-enabled synchrophasor data exchange framework based on Sensor Web

Abstract

Information exchange is difficult and often time consuming in power system because of incompatibility in hardware and software being used in power industry. National Institute of Standards and Technology (NIST) has prescribed several guidelines to ensure interoperability in future smart grid applications. In this paper, we will propose a geo-enabled framework based on Sensor Web to help synchrophasor data exchange without altering existing data acquisition technology being used in industry. It encapsulates existing incompatibility of power system by providing users a web-enabled querying mechanism for synchrophasor data in standards as prescribed by NIST. Data can be queried based on temporal, spatial and comparative parameters giving more control to user to be concise on requirement of data depending upon application. We have utilized open source technologies such as OpenPDC, Sensor Observation Service (SOS) to maximize interoperability.
