NATIONAL FOREWORD

This Indian Standard (Part 1) which is identical with IEC/TR 61850 - 1: 2013 ‘Communication networks and systems for power utility automation - Part 1: Introduction and overview’ issued by the International Electrotechnical Commission (IEC) was adopted by the Bureau of Indian Standards on the recommendation of the Power System Control and Associated Communications Sectional Committee and approval of the Electronics and Information Technology Division Council.

This standard is one of the parts of a series of standards on ‘Communication networks and systems for power utility automation’. The other parts in this series are:

Part 2 Glossary

Part 3 General requirements

Part 4 System and project management

Part 5 Communication requirements for functions and device models

The text of IEC Technical Report has been approved as suitable for publication as an Indian Standard without deviations. Certain terminology and conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:

a) Wherever the words ‘International Standard’ appear referring to this standard, they should be read as ‘Indian Standard’.

b) Comma (,) has been used as a decimal marker while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
