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 related to intelligent electronic devices. The purpose is to provide a compatible 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 is part of a set of definitions that describe a hierarchical power automation communication architecture. This architecture provides abstract definitions of classes and services.

The definition is independent of specific protocol stacks, implementations, and operating systems.

IEC 61850 provides interoperability between various devices.

devices, logical nodes, data, data sets, report controls, or logs) and the services provided by these classes (e.g., read, write, report, define, delete) to achieve communication between these devices.

This document defines the Abstract Communication Service Interface (ACSI) for use in power automation applications where intelligent Real-time collaboration of electronic devices. The Abstract Communication Service Interface (ACSI) is defined to be independent of the underlying communication system.

The Specific Communication Service Mapping 1) (SCSM) is specified in IEC 61850-9-x.

1) ACSI is independent of specific mappings. Mapping to standard application layer or middleware technologies is possible.

This document defines the abstract communication service interface in the following three aspects.

--- A hierarchical class model of all information accessible through a communication network;

---Services that operate on these classes;

---Parameters related to each service.

The technology described by ACSI is abstracted from all the different ways of implementing various devices to work together.

This document does not provide comprehensive tutorial material. It is recommended to read IEC 61850-5, IEC 61850-7-3 before reading this document and IEC 61850-7-3.

IEC 61850-7-1.

NOTE 1 For definitions of general terms, see IEC 60050.

NOTE 2 Abstraction in ACSI has two meanings. First, only real devices (e.g. circuit breakers) or real functions are modeled, which are visible through the communication network and this abstraction results in the hierarchical class model and their behavior defined in this document, IEC 61850-7-3, and IEC 61850-7-4.

The ACSI abstracts from the specific definition of how devices exchange information and only defines the conceptual coordination work. Finally, the specific information exchange is in SCSM (Specific Communication Service Mapping).

Note 3.The examples use the class names defined in IEC 61850-7-3 and IEC 61850-7-4 (e.g. logical node class name XCBR). The standardized names are only used in Defined in IEC 61850-7-4 and IEC 61850-7-3.
