Data modeling method for network message recording analysis device

Abstract

The invention discloses a data modeling method for a network message recording analysis device. The data modeling method is mainly suitable for an intelligent substation which conforms with a standard DL / T 860, takes original message as analysis basis, and uses substation configuration description files as basis; according to the method, spacer layer equipment and substation control layer equipment of the intelligent substation are automatically associated with each other, status information of process layer equipment associated with the spacer layer equipment is judged and analyzed according to a sampled value (SV) message and a generic object oriented substation event (GOOSE) message which are collected by the spacer layer equipment, the key information of analysis and judgment is added into an equipment model file, and data information of a process layer and a spacer layer is sent to the substation control layer equipment in a way of multimedia messaging service (MMS) messages. The data modeling method can achieve the following effects: a great deal of data information of the process layer and the spacer layer can be provided for a background monitoring system in the intelligent substation, so that the efficiency of fault diagnosis is improved, effective guidance is provided for maintainers, and the maintenance convenience of the intelligent substation is improved.

Description

technical field [0001] The invention relates to a data modeling method for a network message record analysis device, which belongs to the field of power grid automation. Background technique [0002] Compared with traditional substations, intelligent primary equipment, networked secondary equipment, and modeled equipment objects are the main features of hierarchically constructed smart substations, which makes the information interaction method of traditional substation equipment no longer applicable in smart substations At the same time, the information interaction system of the smart substation also puts forward new technical requirements for smart devices. At present, based on the IEC61850 protocol, the information exchange between the process layer of the smart substation and the devices at the bay layer uses SV and GOOSE messages to exchange sampling value data, switch status, control commands, etc., and the bay layer devices send MMS messages to the station control lay...

AI Technical Summary

Problems solved by technology

This data communication mode makes it impossible for the substation monitoring system to truly monitor the status and operation of the equipment at the process level

[0004] Second, information interaction between devices at the same level cannot communicate with each other

In the same level of layering, each device is physically connected to each other and functionally independent, and each layer of equipment is responsible for different functional content in the whole station, and there is almost no information exchange between them, which makes the comprehensive application of the whole station caused great limitations
