Abstract

The embodiment of the present invention provides a standard signal transmission method and device for a safety automatic device, including the time synchronization information sent by the master chassis to each slave chassis, and the slave chassis adjust the local clock according to the time synchronization information sent by the master chassis, so as to realize the Synchronize with the time on the local clock between the slave chassis, obtain local data through each slave chassis, and convert the local data into standard local data through each slave chassis, and perform standard local data of the slave chassis through the local clock of the slave chassis For time calibration, the standard local data with time stamps are obtained, and the standard local data with time stamps are sent from the chassis to the main chassis for processing. Solve the problem in the prior art that when the function of the safety automatic device is upgraded, the design of the multiple control systems of the safety automatic device is not fully decoupled, resulting in an increase in the workload of function debugging , a technical problem that reduces system reliability.

Description

technical field [0001] The invention relates to the technical field of power system automation, in particular to a standard signal transmission method and device for a safety automatic device. Background technique [0002] The safety automatic device is an important part of the power system, and it plays a very important role in ensuring the safe operation of the power system. There are two structural forms of power system safety automatic devices: one is the local method, that is, the relevant information of the installation place of the device is collected for processing and judgment. Send an execution order to another place on the spot or through an information channel; the other is a centralized method. That is, in addition to local information. It also collects relevant information of other points in the system through the information channel at the same time, performs comprehensive processing and judgment, and issues execution commands to other points on the spot or ...
