Remote fixed value modification control method and device, computer equipment and storage medium

Abstract

The invention relates to a remote fixed value modification control method and device, computer equipment and a storage medium. The method is applied to a transformer substation, a security gateway is deployed in the transformer substation, the security gateway is in communication connection with a permission workstation deployed in a protection and information master station, and the method comprises the following steps: receiving a service message sent by the protection and information master station through the security gateway; if it is detected that the service message is a remote modification fixed value message, determining a current permission configuration state of the security gateway; when the current permission configuration state is a permission state, forwarding the remote fixed value modification message to an information protection substation in the transformer substation so as to execute remote fixed value modification operation on the transformer substation; and when the current permission configuration state is a non-permission state, modifying the remote modification constant value message, and forwarding the modified remote modification constant value message to an information protection substation in the transformer substation so as not to execute remote modification constant value operation on the transformer substation. By adopting the method, the remote fixed value modification can be safely controlled, and the network security protection in the remote fixed value modification process is enhanced.

Description

Technical field [0001] The present application relates to the field of power systems, particularly to a remote control setting modification methods, apparatus, computer equipment and storage media. Background technique [0002] Currently, in order to improve operation and maintenance efficiency and save manpower resources, the power system more widely through the use of Prudential remotely modify the value of the main station business. Mediator conventional method by channel master station communicates with the substation server front, when the remote operation modified value, the control command issued by operation and maintenance personnel to the internal substation slave station through pre-letter server. [0003] But when the network security issues are being attacked or stolen remotely modify permissions occur, the above method the lack of security control to remotely modify the value of unsafe areas, will lead to a greater security risk. [0004] Thus, the lack of security ...

AI Technical Summary

Problems solved by technology

[0003] However, when network security issues such as being attacked or being stolen remotely modify the authority, the above method lacks security control over remote modification of the fixed value, and there are unsafe links that will cause major security risks

[0004] Therefore, there is a problem of lack of security control over the remote modification of the fixed value of the credit guarantee system in the related technology
