Description

Technical Field

[0001] The present invention relates to the technical field of transformer substations, and in particular to an E-language-based closed-loop setting management system and a method thereof. Background Art

[0002] When setting the protection setting value at the substation site, the data in the paper version of the setting setting order issued by the central dispatching department must first be entered into the relay protection device, or first entered into the monitoring system or the security substation, and then the setting value modification operation must be performed to complete the setting value setting of the relay protection device. When checking the setting value at the substation site, in order to prevent errors from occurring during the previous setting entry (thus making the setting value checking function of the monitoring system or the security substation no longer reliable), the setting value report printed by the relay protection device and the paper version of the setting setting order issued by the central dispatching department are used for manual verification. This shows that setting and checking the setting value requires a lot of manpower, and it is easy to cause entry and verification errors due to fatigue or negligence, leaving major hidden dangers.

[0003] The fixed value data is not a closed loop in the entire fixed value management process. Instead, there are two independent processes: from paper data to electronic data, and then from electronic data to paper data. Moreover, the two types of data cannot be used directly, and both require human intervention, which leads to low efficiency and easy introduction of human errors. Summary of the invention

[0004] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and the invention title of this application to avoid blurring the purpose of this section, the specification abstract and the invention title, and such simplifications or omissions cannot be used to limit the scope of the present invention.

[0005] In view of the above problems existing in the prior art, the present invention is proposed.

[0010] The fixed value setting file parsing template is used to parse the fixed value setting file and form the standard value of the fixed value.

[0019] S5: setting value modification and verification, that is, the setting value modification and verification module communicates with the protection device according to the communication protocol actually used by the protection device;

[0020] When a command to modify the set value of a certain protection device in the main module of the system is manually triggered, the set value modification verification module uses the set value standard value and the set value modification command in the communication protocol to complete the set value modification;

[0021] When a set value check command of a certain protection device in the system main module is manually triggered, the set value modification check module uses the set value read command in the communication protocol to read the current set value, and compares the read current set value with the standard value to generate a check report;

[0099] If the value of the error evaluation function F(E) calculated under the given input is greater than or equal to the second threshold and less than or equal to the first threshold, the calibration result of the fixed value information is determined to be neutral. The neutral result indicates that there is a certain deviation between the current fixed value and the standard value, but the deviation is within the tolerable range, which may be caused by environmental changes or normal equipment drift.
