scope:

The focus of the IEC 61400-25 series is on the communications between wind power plant components such as wind turbines and actors such as SCADA systems. Non-IEC 61850/IEC 61400-25 internal communication within wind power plant components is outside the normative scope of the IEC 61400-25 series.

This document describes how to extend the IEC 61400-25 series with the IEC 618506 Substation Configuration description Language (SCL) file format for describing communicationrelated Intelligent Electronic Device (IED) configurations of a wind turbine, wind power plant controller, meteorological mast, etc. The extension of SCL to the wind domain is intended to simplify integration of wind power plant equipment for clients, as well as their integration to the electrical system. The adoption of SCL allows formalised tool-based exchange of IED parameters, communication system configurations, switch yard (function) structures, as well as description of the relations between them.

The purpose of this format is to formally and efficiently exchange wind turbine and wind power plant IED capability descriptions, and system descriptions between IED engineering tools and the system engineering tool(s) of different manufacturers in a compatible way. The file format is also intended to provide report configuration and alarms as well as HMI interface information from a wind power plant. This information can be used to engineer overlying SCADA systems for the site, for connected DSO, or TSO, or for fleet operators' maintenance and surveillance systems. Finally, the SCL is intended as a documentation of the configuration and topology of the delivered system.

The System Configuration description Language (SCL) is defined in IEC 61850-6, which in turn is based on Extensible Markup Language (XML) version 1.0. Extensions to the IED and communication system model in SCL to cover IEC 61400-25-2 are included in this document. Also Specific Communication Service Mapping (SCSM) extensions or usage rules to cover all mappings defined in IEC 61400-25-4 and IEC 6140025- 41¹ are included in this document.

This document does not specify individual implementations or products using the SCL language, nor does it constrain the implementation of entities and interfaces within a computer system. Further this document does not intend to specify the download format of configuration data to an IED, although the SCL format could be used as part of the configuration data.
