IEC 61850-90-4 TR Communication Networks and Systems for Power Utility

Automation - Part 90-4: Network Engineering Guidelines for Substations

by IEC Technical Committee 57, Working Group 10

The IEC 61850 standard covers a wide range of issues related to the improvement of the reliability, security and efficiency of the electric power grid based on the definitions of the object models of different types of primary and secondary equipment, the communications interfaces required for the operation of the system under normal or abnormal conditions, the configuration language used at all stages of the engineering and maintenance process and many others. However, the standard does not define any specific communications architecture. This is due to the fact that the variety of substation topologies, the criticality of the substations and the performance requirements (to name just a few of the factors that have an impact on the communications architecture) does not allow the definition of a universal communications architecture that will meet the requirements of all substation applications.
