Problems solved by technology

However, this method is cumbersome for the configuration of the switch, which increases the complexity of on-site construction and maintenance. Once the network structure is adjusted, the VLAN must be re-divided, and the workload is relatively large.
At the same time, in the face of different manufacturers, different ages, and different models of switch equipment, a large number of staff and after-sales service personnel from different manufacturers are required to cooperate in the aspects of equipment procurement, design, integration, deployment, maintenance and operation, and upgrading. Leading to long-term high network construction costs and operation and maintenance costs

Embodiment Construction

[0046] To a better understanding of the present invention, the following is a further description of the contents of the present invention in conjunction with the present invention, and the correctness and feasibility of the method are verified by simulation.

[0047] Establishment of the physical port description file.

[0048] The process layer network includes a logical sub-network level, a physical device hierarchy, a physical port level;

[0049] The logical subsite level is divided into several logical subsidies. The subnet uses the "subnet" element definition, with the attribute value including the name, type, description information, "name", "type", "desc". The device physics described in the physical device hierarchy is defined by "Connectedap" element, including: device name and access point defined according to the type of transfer packet, ie "IEDNAME", "APNAME".

[0050] The access point defines a collection of device ports that transmit the same type of packet.

[005...

Abstract

The present invention provides a substation process layer network configuration method and system, including: parsing the device physical port description file pre-built based on substation equipment to form a forwarding strategy supported by the OpenFlow protocol; the forwarding strategy supported by the OpenFlow protocol includes the SDN group Table and flow table; send the group table and flow table to the SDN switch to complete the automatic configuration of the process layer network, improve the work efficiency of the operation and maintenance personnel, improve the security of the process layer network, ensure the safe and stable operation of the electronic system, and improve the power supply Reliability is of great practical significance. The invention has a reasonable design, effectively solves a series of problems caused by traditional switches, reduces the number of messages forwarded by each port of the switch, reduces network congestion, and improves the reliability and real-time performance of message transmission.

Description

Technical field [0001] The present invention relates to the field of substation automation technology, and more particularly to an automatic configuration method and system for a network of intelligent substations. Background technique [0002] As one of the six elections of smart power grid construction, the smart power grid is one of the large-scale operational parameters, control execution points, providing standard, reliable nodes support for smart grids. Substation communication network is a link between various smart electronic devices in the substation. It is the lifeblood of the substation automation system. Its reliability and information transmission rapidly determines the availability of the system. [0003] The communication network is a physical medium interconnected interconnection and interoperability. In an intelligent substation, due to the process layer network needs to transmit and interact data, control data, the effective extraction requirements of data betwe...
