Method for remotely controlling and operating dispatching automation systems by aid of remote-control safety strategy module

Abstract

The invention discloses a method for remotely controlling and operating dispatching automation systems by the aid of a remote-control safety strategy module. The method includes phases of S1, selecting remote-control objects and carrying out double-party confirmation on operators and guardians; S7, carrying out safety verification on attribute definition of databases by the aid of the remote-control safety strategy module; S2, operating and selecting division/reunion; S3, judging whether the attribute definition of the databases passes verification or not by the aid of a five-prevention simulation system; S4, judging whether transformer substations are re-verified or not; S5, executing equipment of the transformer substations; S6, stopping executing the equipment of the transformer substations if the transformer substations fail to be re-verified and the like. The method has the advantages that correct application of remote-control functions further can be guaranteed, remote-control re-verification failure due to errors of the attribute definition of the databases can be reduced, even remote-control error execution can be reduced, and accordingly the safety running level of power grids can be enhanced; remote-control functions are led into a remote-control safety verification module, data maintenance and change conditions do not need to be re-checked by special persons, and the running and maintenance management level of the dispatching automation systems can be upgraded.

Description

technical field [0001] The invention belongs to the technical field of power system maintenance and maintenance, and in particular relates to a remote control operation method of a dispatch automation system using a remote control safety policy module. Background technique [0002] The main functions of the dispatching automation system include five aspects: telemetry, remote signaling, remote control, remote adjustment and communication. Among them, remote control is remote control, which is to issue commands from the dispatching center to realize the operation of remote equipment, and can realize remote control of the operating status of circuit breakers and isolating switches in factories and substations, switching compensation capacitors and reactors, and generator sets. Therefore, whether the remote control function is correct or not has a direct impact on the stable operation of the power system and the safety of electricity consumption. In the actual operation and ma...

Problems solved by technology

[0010] However, there are the following problems in this method of remote control operation of the dispatching automation system: the dispatching automation system is mostly maintained manually and the database is modified and checked, which will lead to the following disadvantages:

[0011] (1) It is necessary to set up a special person to review the data changes, 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 cost of operation and maintenance

[0012] (2) If there is an error in the definition of the database attribute, it will lead to the failure of the remote control to return to school, or even the wrong execution of the remote control, which is not conducive to the safe and stable operation of the power grid
