Introduction

GB/T 30966 "Wind Turbine Wind Farm Monitoring System Communication" defines the information model and information exchange of wind farm monitoring.

It is possible to switch models, thereby enabling commonality of access between different clients and servers from different manufacturers and suppliers. GB/T 30966

The equivalent conversion is mainly based on the international document IEC 61400-25, which defines the communication requirements of the wind farm monitoring system. IEC 61400-

25 chose the modeling approach of abstract definitions such as classes and services, thus making the specification independent of specific protocol stacks, implementation methods, and operating systems. this

The mapping of these abstract classes and services to specific communication protocols is outside the scope of this document, but will be discussed in Part 4 of IEC 61400-25.

GB/T 30966 (all parts) currently consists of the following 6 parts.

--- Part 1. Principles and models. The purpose is to study the general communication between the wind farm SCADA system and the wind turbine

sexual demands.

--- Part 2. Information Model. The purpose is to specify the summary description of the logical node class, the logical node class of the wind farm to the common logical node class

definitions and requirements.

--- Part 3. Information exchange model. The purpose is to specify an information exchange model that can be used by clients and servers to access

The content and structure of the wind farm information model defined in GB/T 30966.2.

--- Part 4. Mapping to the communication protocol. The purpose is to specify a specific mapping oriented to the protocol stack, and provide a link between the client and the remote server.

Provide the required information encoding for information exchange between them.

--- Part 5. Conformance testing. The purpose is to specify the various components (such as wind turbines) and participants (such as wind turbines) in the wind farm

General requirements for communication between SCADA systems), detailing standard techniques for implementing conformance testing, and deterministic

Specific measurement techniques applied when parameters are available.

--- Part 6. Logical node classes and data classes for status monitoring. The purpose is to specify that the condition monitoring information model can represent the information provided by the sensor.

information provided or calculated.

Wind Turbine Wind Farm Monitoring System Communication

Part 4. Mapping to communication protocols

1 Scope

GB/T 30966.4-2023 is Part 4 of the Chinese series on communication for the monitoring and control of wind power plants, and specifies the mapping to the communication profile. The earlier parts define what a wind turbine has to say about itself as an abstract information model - the logical nodes for the rotor, the converter, the yaw system and the rest - and this part is where that abstraction meets a real protocol stack, which is what actually determines whether two vendors' equipment interoperates on a site. The standard sets the general requirements, the protocol stack oriented mapping and the mapping of the Part 3 services onto the stack, with a normative annex on the specific communication service mapping and the web service oriented mapping, and an annex mapping the information model and the information exchange model to OPC XML-DA. It took effect on 1 October 2023.

IEC 61400-25 focuses on the communication between various components (such as wind turbines) and participants (such as SCADA systems) in the wind farm.

General requirements for letters. The internal communication of each part of the wind farm itself is not within the scope of application.

GB/T 30966.5 designed the communication environment supported by the client-server model, defined the following three aspects, and respectively

Modeling is done to ensure scalability of the implementation.

1) Wind farm information model;

2) Information exchange model;

3) The information model and information exchange model are mapped to the standard communication protocol.

The wind farm information model and information exchange model constitute an interface between the client and server. as access to wind farm data

Interpretation framework, wind farm information model provides customers with unified, component-oriented wind farm data through the server. Information exchange model reflects

full functionality of the server. IEC 61400-25 enables communication between different clients and servers from different manufacturers and suppliers

Access is universal.

As shown in Figure 1, the server defined by IEC 61400-25 includes the following aspects.

---Information provided by wind farm components, such as "wind turbine rotor speed" or "total power generation in a certain period of time", these

Information is modeled and can be efficiently accessed. Modeled information is defined in GB/T 30966.2 Information Model;

--- Exchange service of modeled information value, defined in GB/T 30966.3 Information Exchange Model;

--- Mapped to the communication protocol, providing a protocol stack to obtain the exchange value from the modeled information (GB/T 30966.4).

GB/T 30966.5 defines the test cases related to information, service and protocol stack for the consistency test of server and client.

IEC 61400-25 only defines how to model information, exchange information and map to specific communication protocols, and does not include how and where to

Implement communication interfaces, application program interfaces, and recommendations for implementation. However, the purpose of IEC 61400-25 is to obtain

to information related to a single wind farm component such as a wind turbine.

This document specifies a protocol stack-oriented specific mapping to provide the information required for information exchange between a client and a remote server.
