GB/T 42151 "Communication Network and System for Electric Power Automation" defines the communication network and system for electric power automation system, especially for substation

Communication architecture of sub-systems such as station automation system. The sum of all these subsystems can also be the communication body for the whole power system management

The system structure is used to describe the communication between the devices in these subsystems and the communication between the subsystems in the whole power automation system, from variable

Starting from the core requirements of the power station, it meets a large number of requirements required by all functions in the power automation system. Organize data in a data model

These requirements are addressed both in the exchange of data and the resulting 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, thus avoiding the loss of information in communication.

This document is part 5 of GB/T 42151 "Communication Networks and Systems for Electric Power Automation", which defines the functions and equipment of electric power automation systems.

The assignment of functions to devices and control levels is usually not fixed according to the supplier's and user's ideas and the latest technology. therefore,

The standard shall support the assignment of any function. This leads to concerns over different communication interfaces within the substation or power plant, within its borders and beyond.

The mapping of dedicated protocol stacks (Part 8, Part 9) does not change the requirements defined in Part 5.In addition, the general part, requirement specification

and the modeling part is independent of any implementation. The implementations required to use the standard are defined in several dedicated sections dealing with the mainstream means of communication, starting with

This supports the long-term applicability of the standard and its potential for future technological changes.

1 Scope

This document specifies the communication between Intelligent Electronic Devices (IEDs), and the related system requirements for support. This document applies to substation

The power automation system with the station automation system (SAS) as the core.

The technical indicators in this document are the communication requirements for each function in the power automation system. Most of the functions in this document and their communication requirements

The examples are mainly drawn from the substation automation specialist area and, if applicable, can be reused or extended in other areas of power automation. need

Note that the term "substation automation specialist area" is sometimes used instead of the term "substation automation specialist area", especially when considering switchyard equipment

(primary system) and automated system (secondary system).

The description of the function is not used to standardize the function, but to identify the power system between the power plant and the intelligent electronic device in the substation,

Between substations (such as line protection between substations), power plants or substations and upper remote operation centers (such as power grid control centers)

As well as the communication requirements between maintenance centers, the interface with remote technical services (such as maintenance centers) is also considered. Universal range is for power

The communication requirements of the automation system, the basic goal of which is to achieve the interoperability of all interactions and provide seamless communication for the management of the entire power system

system.

The standardization of functions and their implementation is outside the scope of this document. Therefore, it cannot be considered that there is only one single strategy for assigning functions to devices.

In order to support the requirements arising from the free allocation of functions, this document defines the appropriate decomposition of functions into communication-related parts, defines the exchange

data and its required performance.

Similar or identical IEDs from substations, such as protection and control devices, can also be found in other facilities such as power plants.

The use of this document for these devices in power plants facilitates system integration, such as integration between power plant control and associated substation automation systems.
