Use of IEC 61850 object models for power system quality/security data exchange

This paper covers the use of the object models and services of the international standard IEC 61850 for information exchange to support power system quality and security functions. IEC 61850 has many features that make it cost effective, easy to implement and maintain and it may be readily extended to include new devices of interest to the electric utility industry. The object models incorporate basic data types for the common formats used in power system information exchange. Further, the object models are self-defining such that software and/or protocol changes are not required when configuring new and advanced power system applications. Also covered is the status of UCA/sup /spl reg// international, the users group that has assisted with the development of the object models and the related documents.
