Problems solved by technology

Although some user experience can be improved by configuring static multicast or dynamic multicast, these methods have not fundamentally solved the problem of information flow division in relay protection communication networks in smart substations. Operation and maintenance does not provide a convenient method

Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0032] The present invention provides a switch message forwarding method based on a self-defined forwarding table identified by a smart device name applied to a smart substation, including the following process, as figure 1 Shown:

[0033] Step 1. Classification of intelligent equipment: The types of secondary equipment in the intelligent substation are basically determined after the design of the intelligent substation is completed. In this step, after the design of the intelligent substation is completed, it is necessary to count the number and types of equipment in the intelligent substation, such as how many Line protection, how many measurement and control units, etc.

[0034] Statistically classify the function control blocks in the smart substation. The function control block refers to the control block information that completes a specific function i...

Abstract

The present invention provides a method for message forwarding applied to switches in smart substations. The method includes: (1) counting the number and types of smart devices in smart substations; (2) defining the names of the smart devices; (3) automatically Define the forwarding table; (4) check the forwarding table. The invention performs unified verification on the intelligent equipment in the current intelligent substation, improves the integrity and accuracy of the verification, and is beneficial to later maintenance.

Description

technical field [0001] The invention relates to a message forwarding technology of an exchange, in particular to a method and system for forwarding messages of an exchange in an intelligent substation. Background technique [0002] At present, companies in various domestic network provinces have carried out pilot projects of smart substations. In the future, under the background of smart grid construction, the rapid development of smart substations is an inevitable trend, and how to improve the commissioning and construction efficiency of smart substations more efficiently is an urgent problem to be solved. In the development process of substations at the present stage, no matter it is a comprehensive substation, a digital substation or an intelligent substation, more changes occur in the transmission of information flow. However, since the principle of relay protection has not changed, the problems encountered by power system technicians are also concentrated in the proces...
