Intelligent operation and maintenance method for relay protection equipment based on a mobile 5G network

Abstract

The invention discloses an intelligent operation and maintenance method for relay protection equipment based on a mobile 5G network, and the method employs mobile terminal equipment to replace manual on-site recording in the operation and maintenance process of the relay protection equipment, and improves the efficiency and accuracy. The method comprises the steps that firstly, unique identity identification on equipment is collected through mobile terminal equipment, then after information input is completed, the mobile terminal equipment packages the unique identity identification information and standing book information and sends the packaged unique identity identification information and standing book information to a management server through a mobile network, and the management server updates a standing book information table according to on-site input information. The method further supports remote operation and maintenance, image collection equipment is preset around the relay protection equipment, action or state information of the equipment is judged through the image recognition technology, then a relay protection equipment standing book information table is updated correspondingly, and remote operation and maintenance are achieved. The management server is also provided with a data visualization processing module and a data mining module to realize visualization processing and fault pre-tightening analysis of the operation and maintenance data.

[0002] Substation relay protection equipment, as the second line of defense for the safe operation of the power system, is of great significance in ensuring the safety of the power grid. Operation and maintenance procedures, with the development of Internet technology, various departments have also made full use of information management technology in management to ensure that the regulations are implemented in place, and provide basic guarantees for the safe operation and maintenance of relay protection equipment. The collection and verification mainly rely on manual transcription by operators. Only a few manufacturers of relay protection equipment use barcodes to realize equipment identification and management, and have not established association with the current State Grid related operation and maintenance management system and unified identification management

Before the protection equipment is put into operation, the team members need to enter the equipment ledger for the equipment to be put into operation. It takes a lot of manpower and material resources to copy and enter the work, and it is easy to cause clerical errors. During the equipment operation and maintenance period, It is often necessary to have operators regularly and at fixed points to inspect the operation status of the equipment, the calibration cycle and content of the relay protection equipment, the inspection of the relay protection device, the operation and maintenance of the relay protection device, and the status monitoring of the substation protection equipment. It is inconvenient for the staff to manually record the inspection items, which increases the workload of the inspectors, and is not convenient for storage and query. Omissions and negligence make it difficult to detect hidden dangers early, and cannot effectively help managers make auxiliary decisions

With the increase in the number of relay protection equipment, the burden of inspection personnel is heavy, and it also increases the difficulty of asset management, resulting in problems such as untimely data update and difficult to guarantee accuracy.

In the management of relay protection equipment, the management process lacks effective connection, business information cannot be shared, work performance lacks regular evaluation and feedback, and a closed-loop management mechanism for continuous optimization has not been established.
