Building an architecture based on IP-Multicast for large phasor measurement unit (PMU) networks

The document describes a distributed, scalable, secure and standard-based approach for the transmission of synchrophasor data over long distances in order to determine the condition of the electrical power network. With the integration of a high number of renewable and distributed energy resources and the resulting ramifications, such information becomes more and more relevant for the stability of the power grid. The paper focuses on the utilization of IP (Internet Protocol)-based network technologies as the foundation for the transport of synchrophasor data defined by the standard IEC 61850-90-5 in order to support the underlying use cases and applications of the domain such as WAMPAC (Wide Area Monitoring Protection and Control).
