Description

technical field [0001] The invention relates to an emergency protection circuit device of a power grid system, in particular to an integrated verification device for on-site operation and information management of power grid relay protection verification. Background technique [0002] There is a lot of relay protection calibration work in the daily work of the secondary professional of the power system. The traditional on-site calibration is generally carried out by the on-site engineer step by step according to the work instruction in the form of a document. This traditional operation method exists on-site The problem of heavy workload and low efficiency: When the staff performs the inspection work step by step according to the operation instruction on site, it is necessary to continuously set the status of the calibration equipment and input the calibration data, and some data even need to be calculated on site In addition, after the verification is completed, a large amou...

Problems solved by technology

[0002] There is a lot of relay protection calibration work in the daily work of the secondary professional of the power system. The traditional on-site calibration is generally carried out by the on-site engineer step by step according to the work instruction in the form of a document. This traditional operation method exists on-site The problem of heavy workload and low efficiency: When the staff performs the inspection work step by step according to the operation instruction on site, it is necessary to continuously set the status of the calibration equipment and input the calibration data, and some data even need to be calculated on site In addition, after the verification is completed, a large amount of temporarily recorded data needs to be sorted into a verification report, which is a heavy workload and may easily cause some verification data to be lost

[0005] 1. Due to the fact that the test operation of the commonly used on-site calibration equipment is not friendly enough and lacks intelligent operation, its inspection operation relies on technical personnel with high professional requirements, resulting in high requirements for human resources and gaps in the maintenance calibration: on-site calibration The work requires experienced professional and technical personnel, familiar with the calibration process, skilled in equipment operation

The training of such personnel generally requires a certain period. With the continuous increase of secondary equipment in the current power system, professionals who can meet the above technical requirements begin to become tense.

[0006] 2. On-site supervision is difficult: From the assignment of on-site maintenance and calibration tasks, to task execution operations, to result feedback, etc., the work of each link depends on the responsibility of the staff, and the status of maintenance and calibration can only be obtained from the school. reflected in the test report

However, in actual work, especially in the verification work of some new projects, it is found that the phenomenon of missing verification and fabricating verification reports has left hidden dangers for the safe operation of secondary equipment in the future.
