Problems solved by technology

[0003] 1. The on-site work is heavy and the efficiency is low: when the staff performs the inspection work step by step according to the operation instructions on the site, it is necessary to continuously set the status of the calibration equipment and input the calibration data, and some data even need to pass On-site calculation can only be obtained, and the efficiency is low; in addition, after the calibration is completed, a large amount of temporarily recorded data needs to be sorted into a calibration report, which is a heavy workload and easily causes some calibration data to be lost
[0004] 2. High requirements for human resources and gaps appear: On-site calibration requires experienced professional and technical personnel, who are familiar with the calibration process and 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.
[0005] 3. 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
[0006] 4. The currently widely used on-site calibration equipment is not friendly enough for test operation, lacks intelligent operation, and still relies on technical personnel with high professional requirements

Embodiment

[0035] With the rapid development of modern information technology, my country's power system and related equipment are gradually moving towards the direction of intelligence. The scale of the power system continues to expand, and the system has higher and higher requirements for automation. Therefore, the present invention utilizes the convenience and openness of mobile devices to develop a relay protection verification system based on mobile internet technology to realize automatic configuration of the verification process, automatic entry of typical parameters, pre-preparation and automatic calculation of test data, and The verification report is automatically generated afterwards. At the same time, the data cross-link interface between the mobile device and the verification device is started to realize the issuance of the verification data and the return of the verification result data, which greatly reduces the data operation on the spot. All verification processes can be...

Compared with the prior art, the relay protection test system based on themobile platform has the advantages that the working efficiency is greatly improved; the reliability of the test process is ensured; the reliability performance of data communication is stable; operation and management are facilitated; and the like.

Description

Technical field [0001] The invention relates to a relay protection test system for a power system, in particular to a relay protection test system based on a mobile platform. Background technique [0002] With the birth and development of power systems, relay protection came into being. The importance of relay protection in the power system is self-evident, so the relay protection verification device plays a pivotal role in the stable operation of the entire power grid. There are a lot of relay protection verification work in the daily work of the secondary operation of the power system. The traditional on-site verification is generally performed by the on-site engineer according to the work instruction in the form of a document. This method has the following in practical applications a few questions: [0003] 1. The workload of on-site operation is large and the efficiency is low: when the staff perform inspection work according to the operation instructions and step by step, th...
