Abstract

The invention discloses a substation field constant value checking method, and relates to the technical field of electric power engineering. The checking method comprises the following specific checking steps: S1, firstly, importing a newest setting value list through a client module, and storing the newest setting value list in a database module by a conversion module; s2, using the client module to send a checking instruction to the online monitoring module by means of the conversion module and the communication service module; and S3, after the online monitoring module receives the checking instruction, calling constant value information of the protection device and uploading the constant value information. The method is different from the traditional method of manually comparing and checking the constant value of the protection device, the comparison and checking of the constant value are completely automatic, the method not only can save a large amount of manpower, but also can save a large amount of time and energy of employees, the automatic checking is realized, the checking report is generated, the checking result is not easy to generate missing items and errors, and the working efficiency is improved. And error setting of the protection device can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of electric power engineering, in particular to an on-site fixed value checking method of a substation. Background technique [0002] The protection device is an important equipment to ensure the safe and stable operation of the power grid, and the correctness of the protection setting is the key to the correct operation of the protection device. At present, the calculation of the protection setting value of the power grid company is completed by the dispatching department. After the review and approval process, it is sent to each execution unit in the intelligent dispatching management system, and then the equipment maintenance personnel complete the execution of the setting value. Complete the execution and archiving process in The current working mode of comparison of the fixed value of the protection device is: the protection personnel work in groups of two, read the fixed value and operate on the devic...
