Secure switching module for primary and secondary units of telecontrol machine and switching method of secure switching module

Abstract

The invention discloses a secure switching module for primary and secondary units of a telecontrol machine and a switching method of the secure switching module. The secure switching module for the primary and secondary units of the telecontrol machine comprises a starting module, a preselection module and a self-inspection module, wherein the starting module is connected to the self-inspection module through the preselection module; the starting module comprises a periodic self-starting module and a manual starting module; the preselection module comprises a transformer substation checking module, a telecontrol machine checking module and a key checking module; and the self-inspection module comprises a hardware self-inspection module, a software self-inspection module and a channel detection module. According to the secure switching module for the primary and secondary units of the telecontrol machine and the switching method of the secure switching module, the correctness of primaryand secondary switching operation is guaranteed; a switching failure and even occurrence of mis-execution of switching due to a manmade mistake or equipment abnormality are reduced; and the secure operation level of scheduling of automatic operation and maintenance is increased.

Description

technical field [0001] The invention relates to the technical field of power grid communication, in particular to a safety switching module of a remote machine main machine and a standby machine and a switching method thereof. Background technique [0002] The dispatching automation system is a data processing system based on computer, communication, and control technologies that provides online operation information, analysis and decision-making tools, and control means for production and operation personnel of electric power dispatching institutions at all levels. The stable operation of the dispatching automation system is the basis for ensuring the safe, economical, stable and reliable operation of the power grid. In actual operation, the remote machine sends the station-side data to the main station, and the remote control and remote adjustment strategies issued by the master station of the dispatch automation system are received by the station-side remote machine to re...

AI Technical Summary

Problems solved by technology

[0006] (1) It is necessary to assign a special person to carry out the work of the main and standby cutting machines, and the artificial operation efficiency affects the improvement of the automation level

That is to say, this model increases the consumption of labor costs and also increases the operation and maintenance costs;

[0007] (2) When the equipment is transformed or the remote machine is abnormal, the main and standby machines are switched off. If the equipment of the standby machine is abnormal at this time, the data exchange function between the station and the main station will be lost, and even the remote control and remote adjustment functions will be lost.

It is not conducive to the safe and stable operation of the power grid
