Communication method, device and system between security and stability control devices based on Ft3 protocol

Abstract

Disclosed is a communication method, device and system between security and stability control devices based on an FT3 protocol. The method comprises the step of: acquiring FT3 messages written by an application program of the sending end security and stability control device, wherein the FT3 messages comprise data to be sent, and the data to be sent comprises a conventional command and a test command; sending the FT3 message containing the test command to the receiving end security and stability control device through a first sending queue, sending the FT3 message containing the conventional command to the receiving end security and stability control device through a second sending queue, wherein the sending priority of the first sending queue is higher than that of the second sending queue; and receiving feedback information sent by the receiving end security and stability control device according to the test command, so that the application program of the sending end security and stability control device reads the feedback information and determines whether communication is normal or not according to the read feedback information. Therefore, normal operation of the security and stability control system can be ensured, and loss caused by failure of the security and stability control system is avoided.

Description

technical field [0001] The present invention relates to the communication field, in particular to a communication method, device and system between safety and stability control devices based on the Ft3 protocol. Background technique [0002] With the rapid development of the economy, the power system has also made great progress, the capacity of the power grid is getting larger and larger, and the structure of the power grid has become more complex. The security of the power grid will seriously affect the implementation of social stability and production, so the protection measures of the power grid are becoming more and more strict and more refined. Among them, the safety and stability control device, as the important equipment of the second line of defense of the power system, is also more and more widely valued by the power system. The safety and stability control device does not use a single device to protect the power grid, but forms a safety and stability control syst...

AI Technical Summary

Problems solved by technology

[0006] Although the function of the stability control device can be realized only by relying on real commands, the execution result of the stability control cannot be guaranteed

For example, when the link between the master station and the sub-station or the sub-station and the execution station is abnormal, or when the sub-station or the execution station is down abnormally, it will cause the sub-station or the execution station to be unable to effectively execute the sender command, and the sender cannot be the first Notified of communication abnormalities in time, commands are still sent to sub-stations or execution stations, resulting in failure of the safety and stability control system, which will lead to immeasurable losses when the power grid operates abnormally
