specific measurement techniques:

GB/T 42151 "Power Automation Communication Networks and Systems" defines communication networks and systems for power automation systems, especially power substations:

Communication architecture of subsystems such as station automation systems: The sum of all these subsystems can also contribute to the communication body of the entire power system management:

The architecture describes the communication between devices in these subsystems and the communication between subsystems in the entire power automation system:

Starting from the core needs of the power station, it meets a large number of requirements for all functions in the power automation system: Organize data in a data model these requirements are raised in the data exchange and data exchange that generates services: The performance of data exchange means not only the transmission time of data exchange, but also it also means the quality of data exchange, thereby avoiding the loss of information during communication:

This document specifies the data model and abstract communication service interface and manufacturing message specification (MMS) of the GB/T 42151 series of standards and Implementation details of mapping between Ethernet technologies, such as the correspondence between ACSI communication services and MMS communication services, etc:, at the same time this article the software also considers support for network security and accurate time synchronization technical solutions: This document is intended for manufacturers, users and it is of great significance for the quality inspection center to correctly implement, use and test the products and systems of GB/T 42151:

1 Scope

1.1 General

This document specifies the real-time and non-real-time capabilities of local area networks by mapping ACSI to MMS and ISO/IEC 8802-3 frames:

Methods of data exchange:

MMS services and protocols are specified to run over a fully compatible set of OSI and TCP communication protocols: MMS supports both centralized and Distributed architecture data exchange: This document includes the exchange of real-time data indications, control operations, and report notifications:

This document specifies ACSI (Abstract Communications Services Interface, IEC 61850-7-2) objects and services to MMS (Manufacturing Message Specification, Mapping of ISO 9506) and ISO/IEC 8802-3 frames:

This document also specifies the mapping of real-time information to non-MMS protocols: The semantics of this protocol are specified in IEC 61850-7-2: This article the document contains protocol syntax, specifications, mapping to ISO/IEC 8802-3 frame format, and tools related to the use of ISO/IEC 8802-3:

body method:

The mapping from ACSI to MMS specifies how to use MMS concepts, objects and services to implement ACSI concepts, objects and services:

This mapping enables interoperability between functions implemented by different manufacturers:

This document specifies the standard method for data exchange using ISO 9506 services: For those specified in IEC 61850-7-2 for ACSI services directed to MMS, this document will specify other protocols: This document uses an object-oriented approach and is based on the external application of the actual device:

Conforms to data and behavior, describing the actual device: These objects themselves are abstract and can be applied in a wider range of applications: This application has exceeded the application scope of power automation communication has been expanded:

This document provides a mapping of objects and services specified in IEC 61850-7-2, IEC 61850-7-3 and IEC 61850-7-4:
