Method and device for modifying fixed value based on credit guarantee system and fixed value setting system

Abstract

The invention discloses a fixed value modifying method and equipment based on a credit guarantee system and a fixed value setting system. The method includes the following steps: the website server in the safety area III sends the setting file to the application server in the safety area II through reverse isolation; the application server analyzes the setting file and generates a corresponding setting modification command; The application server modifies the corresponding setting value of the corresponding protection device in the substation management machine in the safety zone II according to the setting modification command. Through the above-mentioned implementation manner, it is possible to modify the fixed value online, save time and manpower, and adjust the fixed value in time to help ensure the operation safety of power equipment at all levels.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a fixed value modification device based on a credit guarantee system and a fixed value setting system. Background technique [0002] In the field of electric power technology, in order to ensure the normal operation of operating equipment at all levels, it is necessary to regularly and timely find out whether there is an error in the fixed value area code and the setting value of each area in the protection device connected to the operating equipment at all levels for power-off protection, and give an early warning. [0003] In the prior art, the fixed values ​​at the substation management machines used to monitor the status of operating equipment at all levels usually need to be adjusted in a timely manner according to factors such as seasonal changes, and the substation management machines are often located in relatively remote areas. The above fixed values ​​are usually...

[0003] In the prior art, the fixed values ​​at the substation management machines used to monitor the status of operating equipment at all levels usually need to be adjusted in a timely manner according to factors such as seasonal changes, and the substation management machines are often located in relatively remote areas. The above fixed values ​​are usually It is necessary for the maintenance personnel to go to the place where the substation management machine is located to input and modify the fixed value manually, which is a waste of time and manpower, and at the same time, the fixed value cannot be adjusted in time
