Remote on-line management and control device for configuration information of secondary equipment in intelligent substation

Abstract

The invention discloses a remote on-line management and control device for configuration information of secondary equipment in an intelligent substation, which aims to solve a technical problem of ensuring the operation safety of the intelligent substation. The remote on-line management and control device is provided with a dispatching terminal management and control system and an intelligent substation configuration file calling and comparison device, the dispatching terminal management and control system performs comparative analysis on real-time and returned secondary equipment configuration description files, verification information of secondary circuit instance configuration files and cyclic redundancy check codes of secondary equipment, gives an alarm to the management personnel ofthe dispatching terminal management and control system for inconsistent information, and the intelligent substation configuration file calling and comparison device obtains the real-time secondary equipment configuration description files, the verification information of the secondary circuit instance configuration files and the cyclic redundancy check codes of the secondary equipment. Compared with the prior art, the remote on-line management and control device realizes real-time early warning for inconsistent secondary equipment configuration files of the dispatching terminal, provides real-time monitoring of the configuration files of the secondary equipment for the operation and maintenance personnel of the intelligent substation, and ensures the operation safety of the intelligent substation.

Description

technical field [0001] The invention relates to a protection device of a smart grid, in particular to an online comparison and checking device for a configuration file of a protection device of a smart substation. Background technique [0002] In the existing technology, the personnel at the dispatching end (dispatching end) of each province and city of the power grid lack the means to remotely and online timely perceive whether the configuration file of the secondary equipment of the smart substation is inconsistent with the configuration description file SCD of the smart substation archived at the dispatching end, but mainly use manual methods , through the inspection personnel in the smart substation, copy the SCD from the secondary equipment (secondary equipment, device) of the smart substation, and perform manual verification. This method requires manual data transmission, which is not only inefficient, but also the storage device (such as U disk, mobile hard disk) is e...

Problems solved by technology

[0002] In the existing technology, the personnel at the dispatching end (dispatching end) of each province and city of the power grid lack the means to remotely and online timely perceive whether the configuration file of the secondary equipment of the smart substation is inconsistent with the configuration description file SCD of the smart substation archived at the dispatching end, but mainly use manual methods , through the inspection personnel to the smart substation for inspection, copy the SCD from the secondary equipment (secondary equipment, device) of the smart substation, and perform manual verification

This method requires manual data transmission, which is not only inefficient, but also the storage device (such as U disk, mobile hard disk) is easy to carry viruses, which may cause data loss, resulting in certain hidden safety hazards in the power grid, which is not conducive to the operation of smart substations Safety
