Novel efficient protection information substation based on IEC61850 standard and implementation method thereof

Abstract

The invention discloses a novel efficient protection information substation based on IEC61850 standard and an implementation method thereof. A spacer-layer network interface of an information substation receives an uplink MMS message of a relay protection device; a server process replaces a domain name element in an uplink MMS original message with a domain name of the dispatched-distributed protection information substation; a gateway network interface sends the uplink MMS message to dispatch; the gateway network interface receives a downlink MMS message of the dispatch; the server process converts the domain name element in the downlink MMS message into a corresponding relay protection device domain name; and the spacer-layer network interface directly sends the downlink MMS message to the relay protection device. The novel efficient protection information substation based on IEC61850 standard and the implementation method thereof in the invention greatly improve the data processingefficiency and processing capacity of the protection information sub-station; true to the original message sent on the relay protection device, the structure of the original message is kept unchanged;faults can be located rapidly; moreover, the memory resource used is less; configuration update and re-debugging are not required in extension and renovation of a transformer substation.

Description

technical field [0001] The invention relates to the communication field of protection information sub-stations, in particular to a novel high-efficiency protection information sub-station based on the IEC61850 standard and its realization method. Background technique [0002] The current protection information substation device adopts two independent program modules or processes, which are respectively a client process and a server process. The client process communicates with the relay protection equipment, and the server process communicates with the dispatch center. Between two independent processes / modules inside the protection information sub-station, a database is used to store and convert information. The client process adopts the 61850 standard to establish communication with the relay protection equipment, collect the relay protection equipment information, and store the relay protection equipment data information into the local historical database and real-time da...

AI Technical Summary

Problems solved by technology

[0006] 1. The original information that the client interacts with the relay protection needs to go through the process of local decoding, storage and re-encoding

The decoding, storage, and encoding stages consume a lot of CPU resources, causing serious delays in information transmission.

[0007] 2. The original information is structurally damaged

In the case of communication failure and message loss, the dispatching system cannot know whether it is caused by the failure of the protection information substation or the failure of the relay protection equipment

[0009] 4. The current technical solution, database and encoding and decoding all need to consume a lot of memory
