Embodiment Construction

[0034] In order to better understand the present invention, the content of the present invention will be further described below in conjunction with the accompanying drawings and examples.

[0035] The invention provides a method for unified management of the communication network of the intelligent substation, such as figure 2 As mentioned above, the smart substation is structurally divided into station control layer equipment, bay layer equipment, process layer equipment, station control layer network and process layer network, and functionally divided into process layer and station control layer:

[0036] The station control layer equipment and the interval layer perform information transmission through Ethernet, and the interval layer equipment communicates with the process layer equipment through optical cables;

[0037] The interval layer device bridges the station control layer network and the process layer network.

[0038] The process layer equipment includes: the i...

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,...
