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. These The mapping of abstract classes and services to specific communication protocols does not belong to the scope of this document, but will be discussed in GB/T 30966.4.GB/T 30966 mesh The former 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 2.Information Model

1 Scope

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. IEC 61400-25 designs the communication environment supported by the client-server model, defines the following three aspects, and respectively Modeled to ensure scalability of implementation. a) wind farm information model; b) information exchange model; c) The information model and information exchange model are mapped to standard communication protocols. 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, the wind farm information model provides unified, component-oriented wind farm data to the client through the server. information exchange model Reflects the full functionality available on the server side. IEC 61400-25 enables different clients and services from different manufacturers and suppliers Access between server terminals is connected. As shown in Figure 1, the server side 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; --- 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). 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 the information model of equipment and functions related to wind farm applications, and in particular specifies the communication between wind farm components. Compatible with logical node names and data names, including the relationship between logical devices, logical nodes and data. The names defined by IEC 61400-25 are Used to create hierarchical object references for communication between wind farm components. This document specifies the common attribute types and common data classes related to the application of wind turbines, especially the following common data types Data category. --- set value; ---status value; ---Call the police; ---Order; --- event count; ---Status sequence; ---Alarm setting status. ......
