Embodiment Construction

[0037] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0038] According to the dynamic bandwidth allocation method for IEC 61850 communication based on SDN, the steps are as follows:

[0039] Step 1: Model the SDN controller hierarchically based on the IEC 61850 standard, and configure the corresponding SCD file for the SDN controller;

[0040] Step 2: Map the network service in the SDN controller to ACSI service, and provide the ACSI service to the application in the substation;

[0041] Step 3: Construct the communication protocol stack structure of the ...

Abstract

The invention provides an SDN (Software Defined Networking) based IEC 61850 communication oriented dynamic bandwidth distribution method. The SDN based IEC 61850 communication oriented dynamic bandwidth distribution method comprises a first step of performing hierarchical modeling for an SDN controller based on an IEC 61850 standard; a second step of mapping a network service in the SDN controller into an ACSI (Abstract Communication Service Interfaces) service; a third step of building a communication protocol stack structure of IEC 61850 based transformer substation IED (Intelligence Electric Devices), the SDN controller of the IEC 61850 standard and a switch of OpenFlow; and a fourth step of, by the SDN controller, controlling an infrastructure to distribute a corresponding bandwidth for each transformer substation IED through a network, and monitoring the bandwidth distribution condition. The SDN based IEC 61850 communication oriented dynamic bandwidth distribution method makes up the defect on a network sensing function of a smart grid automatic management system, distributes network bandwidth resources dynamically and in real time for flow with different priorities and guarantees the best delivery performance in an end-to-end communication process of the transformer substation.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an SDN-based dynamic bandwidth allocation method for IEC 61850 communication. Background technique [0002] In recent years, low-carbon energy conservation and environmental protection has become a hot issue of social concern, and it is also an important part of the implementation of the national sustainable development strategy. As an important application scenario of the Internet of Things, smart grid aims to provide two-way interactive intelligent services for power system management and end users by using the most advanced information and communication technology. It has become the mainstream trend of the future development of power grid technology. From electric energy generation to transmission, and then used by users, the smart grid will mainly monitor seven important links in the life cycle of electric energy: 1) power generation, 2) power transformation an...
