Introduction

GB/T 42151 "Electric Power Automation Communication Network and System" aims to provide interoperability for all devices in the electric power automation system:

It consists of the following parts:

--- Part 1: Introduction: The purpose is to introduce the overview of this document:

--- Part 2: Terminology: The purpose is to list the terms and definitions used in this document:

--- Part 3: General requirements: The purpose is to introduce the overall requirements of communication networks, with an emphasis on quality requirements:

--- Part 4: System and project management: The purpose is to describe the requirements for system and project management processes and the requirements for engineering and testing

Dedicated support tools required:

--- Part 5: Communication requirements for functions and device models: The purpose is to specify the communication requirements for various functions of the power automation system:

--- Part 6: Communication configuration description language for power automation systems associated with intelligent electronic devices: The purpose is to

exchange of intelligent electronic device capability descriptions in a way that allows for the exchange of power automation system capabilities between tools provided by different manufacturers

describe:

--- Part 7: Basic communication structure of power automation system: The purpose is to define a hierarchical class model and the services provided by these classes:

services to enable communication between devices:

--- Part 8: Specific communication service mapping SCSM: The purpose is to provide substation control layer and bay layer and station control layer and

Communication mapping between bay layers:

--- Part 9: Specific communication service mapping SCSM: The purpose is to provide substation bay layer and process layer and bay layer and

Communication mapping between process layers:

--- Part 10: Conformance testing: The purpose is to specify the standard technology for implementing conformance testing and to use when proposing performance parameters

specific measurement techniques:

This document introduces a machine-processable file to describe the data model of the relevant parts of IEC 61850 (all parts) and to serve as a

input to improve the interoperability of IEC 61850: This is the purpose of this document to define a new language namespace definition (NSD): This will avoid

Manually input the data model content in IEC 61850 (all parts) using engineering tools related to the IEC 61850 data model

This will also help make it easier to make any corrections to the data model as needed to achieve interoperability: Tool vendors

Can integrate NSD into their tools and distribute standard data models directly to end users:

The description of the namespace concept and the relationship between namespaces are defined in IEC 61850-7-1: The creation of namespaces (domains, products, etc:)

The creation process is defined by IEC 61850-1-2:

Model machine processable format

1 Scope

1:1 General

This document specifies a method for converting the IEC 61850 data model (e:g:, description logical nodes, common data classes, structured data attributes,

Code components (such as enumeration tables) are modeled as methods in XML format that can be imported and parsed by tools: The following main use cases are supported:

* Generation of SCL data type templates for system specification files or ICD files;

* SCL data type template verification;

* Private extension definitions following the rules of IEC 61850 (all parts);

* When a new version of the IEC 61850 data model (supplement, errata or tissue) affects the content of IEC 61850 (all parts), quickly

Adapt to the entire engineering chain;

* Provide tool users with tool-independent text help on data model content;

* Support multi-language publishing, that is, through machine-processable formats, support expressing data models in different languages:

This document is limited to publishing in XML format, which should support the relevant data model content in IEC 61850 (all parts):

The publication itself will be the content of the relevant parts of IEC 61850 (all parts), and IEC 61850-1-2 will be described as the core data model:

Generate NSD files for other purposes as required:
