Full-station communication network unified management method for intelligent substation

Abstract

The invention relates to a full-station communication network unified management method for an intelligent substation. The method comprises the following steps: setting a CPU port VLAN (Virtual Local Area Network) of a switch of an independent network; classifying a cascade port among the switches in the independent network into the VLAN; classifying the port of the switch connected with a webmaster switch into the VLAN; distributing a management IP to the switch in the independent network; starting up an LLDP (Link Layer Discovery Protocol) function of the switch, and implementing unified management of the communication networks of the full station. The scattered communication networks are connected through a management network, the newly added wiring networking does not affect the existing business due to the existence of the independent VLAN, and in addition, the network wiring and the operation of classifying the VLAN on the switch are not complicated and are relatively simple in project implementation.

Description

technical field [0001] The invention relates to the technical field of intelligent substation network communication, in particular to a method for unified management of the communication network of the intelligent substation. Background technique [0002] Substation, a place where voltage is changed. In order to transmit the electric energy from the power plant to a distant place, the voltage must be raised to become high-voltage electricity, and then the voltage is lowered as needed near the user. This work of raising and lowering the voltage is done by the substation. The main equipment of substations are switches and transformers. According to the size, the small ones are called substations. A substation is larger than a substation. Substation: generally a step-down substation with a voltage level below 110KV; substation: including "boost and step-down" substations of various voltage levels. A substation is a power facility in the power system that transforms voltage,...

Problems solved by technology

[0007] Since the current communication network in the smart substation is composed of multiple independent networks, the LLDP protocol can only obtain the topology of each network separately, and cannot achieve unified network management. Therefore, there is an urgent need for a unified management method for the communication network. The whole station communication network can be constructed into a unified management network
