Abstract

The invention relates to an information protection substation and a priority response method thereof for a master station command. The application management module sends a channel state query message, and the communication module receives the channel state query message, a channel number, a channel state and a channel priority corresponding to a channel are written into a query confirmation message and the query confirmation message is returned if the priority level is not lower than the priority level and the channel state is a channel with a command to wait for execution; otherwise, the query confirmation message is not returned; if receiving the query confirmation message, the application management module sends an execution permission message; the communication module receives the execution permission message and controls the state of the corresponding channel to be switched to a state that a command is being executed; and if the query confirmation message is not received, the priority level is reduced step by step, and the channel state query message is resent, so as to solve the problem in the prior art that how to process the command according to different priority levels in the master station and the sub-station does not exist.

Description

technical field [0001] The invention relates to a trustworthy substation and its priority response method for a command of a master station, and belongs to the technical field of power system automation. Background technique [0002] The relay protection fault information processing system plays an increasingly important role in the stable operation of the power grid. The stable operation of the power system is inseparable from various relay protection devices. The Baoxin sub-station is responsible for remote transmission of the relay protection device information at the station end To dispatch and receive various calls and control commands from dispatch at the same time. Now unattended substations have become a development trend, and Baoxin substations have become a key means for the main station to keep abreast of the operation of the protection devices in the station. [0003] The current application scenario of Baoxin substation is to configure one Baoxin substation at ...
