Embodiment 1

[0053] An embodiment of the present invention provides an IED device learning method in a smart substation, such as figure 1described, including the following steps:

[0054] (1) Carry out message type identification to the received message;

[0055] (2) Based on the message type recognition results and the set processing rules, extract and manage the characteristic information of the IED equipment, and complete the learning of the IED equipment in the smart substation.

[0056] In a specific implementation manner of the embodiment of the present invention, the feature information of the IED device is extracted and managed based on the message type identification result and the set processing rules, specifically:

[0057] When the message is a goose, sv or mms message, the feature information of the IED equipment in the message is extracted, and the feature information of the extracted IED equipment is managed; otherwise, the received message is processed Forward processing....

Embodiment 2

[0072] Based on the same inventive concept as in Embodiment 1, the embodiment of the present invention provides an IED device learning system in a smart substation, including a processor and a storage medium;

[0073] The storage medium is used to store instructions;

[0074] The processor is configured to operate according to the instructions to execute the steps of the method according to any one of Embodiment 1.

Embodiment 3

[0076] An embodiment of the present invention provides an IED device learning system in a smart substation, such as figure 2 shown, including network coprocessors and memory;

Abstract

The invention discloses a learning system and method for IED equipment in an intelligent substation. The method comprises the steps that a network coprocessor performs message type identification on areceived message; and based on the message type identification result and a set processing rule, the network coprocessor extracts and manages the feature information of the IED equipment to completethe learning of the IED equipment in an intelligent substation. According to the method, the information of the IED equipment connected with a switch interface is learned in real time; errors caused by configuration and wiring can be quickly found and positioned; the debugging efficiency is improved; potential safety hazards are eliminated; and safe operation of a power system is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of power system automatic control and network communication, and in particular relates to a learning system and method for IED equipment in an intelligent substation. Background technique [0002] With the gradual promotion of smart substation technology, the monitoring system based on the network transmission of data information is gradually replacing the traditional mode based on the hard connection of secondary cables. At present, the smart substation network logically consists of a station control layer network, a bay layer network and a process layer network, and physically configures two layers, namely, the station control layer and the process layer. The automation equipment in the station conducts unified modeling according to the IEC61850 standard, applies the unified data interface model defined by IEC61850, and realizes information sharing and interaction through the station control layer MMS netw...
