Communication networks and systems for power utility automation - Part 90-1: Use of IEC 61850 for the communication between substations
IEC/TR 61850-90-1:2010(E) provides a comprehensive overview on the different aspects that need to be considered while using IEC 61850 for information exchange between substations. In particular, this technical report defines use cases that:
- require an information exchange between substations;
- describes the communication requirements;
- gives guidelines for the communication services and communication architecture to be used;
- defines data as a prerequisite for interoperable applications;
-describes the usage and enhancements of the configuration language SCL.
