scope:

IEC TR 61850-90-14:2021(E), which is a technical report, specifies the information model of devices and functions related to systems of power utility automation, specifically related to FACTS (Flexible AC Transmission Systems) and Power Conversion applications. The IEC 61850-90-14 information model standard utilizes existing IEC 61850-7-4 logical nodes where possible, but also defines specific logical nodes where needed. Specifically, the scope of this document: • Covers communication between control system of FACTS, HVDC and Power Conversion and SCADA and HMI systems • Includes the data model for FACTS, HVDC and Power conversion devices • Does not cover Protection relays • Does not cover process bus • Does not cover valve communication
