Problems solved by technology

At present, the operation information collected by the power distribution terminal is transmitted to the main station system using conventional communication protocols, lacking a description of the meaning (source) of the data, that is, the lack of self-describing information. In actual engineering, the communication between the main station system and the terminal Special files (such as point tables) are required to explain the specific data meaning, which reduces the interoperability between the distribution terminal and the control center. At the same time, the workload of installation, modulation, management, and maintenance is large, and it cannot adapt to the development of smart distribution networks. needs

Embodiment Construction

[0020] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] The mapping method from 61850 abstract service to 61968 message mechanism includes the following steps:

[0022] Step 1. Define the message topic of IEC61850 functional communication, and realize the correspondence from IEC61850 abstract service to IEC61968 message topic;

[0023] The value of the verb has been specified in the IEC61968 standard. To realize the mapping of the IEC61850 message, only the noun in the message header needs to be customized according to the standard service type, and the verb in the message header adopts the specified value in the IEC61968 standard.

[0024] According to the service interface specified in IEC61850, the message subject of the customized IEC61850 functional communication is shown in the following table:

[0025]

[0026]

[0027] Step 2. Fill the message carrier of the IEC61850 functional communi...

Abstract

The invention relates to an IEC61850 abstract service to 61968 message mechanism mapping method. The method comprises a first step of defining a message subject of IEC61850 functional communication and implementing the correspondence of an IEC61850 abstract service to the IEC61968 message subject; a second step of filling a message carrier of the IEC61850 functional communication, and effectively encapsulating business data of the IEC61850 function into the IEC61968 message carrier; and a third step of transmitting the encapsulated IEC61850 business data by way of Web Services communication. According to the invention, equipment and a bus are seamlessly connected and the information sharing between application systems is improved; the further application of the modeling idea is ensured and the interoperability among the equipment is improved; and the IEC61850 standard application is extended and is no longer merely limited to substation automation.

Description

technical field [0001] The invention belongs to the field of electric power automation communication, and in particular relates to a mapping method from 61850 abstract service to 61968 message mechanism. Background technique [0002] IEC61968 is a communication protocol standard for distribution network automation (DA). It tends to use the message-driven mechanism of each distribution network application system, and realize the exchange of business data by the middleware service of agent message routing, that is, the enterprise service bus (ESB). Among them, the distribution network master station and the terminal are important components of the distribution network automation application. At present, the operation information collected by the power distribution terminal is transmitted to the main station system using conventional communication protocols, lacking a description of the meaning (source) of the data, that is, the lack of self-describing information. In actual en...
