This part of IEC 61850 provides a way of exchanging synchrophasor data between PMUs, PDCs WAMPAC (Wide Area Monitoring, Protection, and Control), and between control center applications. The data, to the extent covered in IEEE C37.118-2005, are transported in a way that is compliant to the concepts of IEC 61850.

However, given the primary scope and use cases, this document also provides routable profiles for IEC 61850‑8‑1GOOSE and IEC 61850‑9‑2SV packets. These routable packets can be utilized to transport general IEC 61850 data as well as synchrophasor data.
