On-site Smart Operation and Maintenance System for Substation Equipment Based on Mobile Network

Abstract

Abstract-The maintenance of substations is crucial for the safety of the electrical grid and power industry. However, for long time, the maintenance teams in the field and the experts in the power companies are divided. The data and expertise exchanges between the on-site maintenance teams and data center are delayed due to the lack of effective communication. This paper introduces an on-site smart operation maintenance system for substation equipment based on mobile network. It is able to establish real-time communication and data exchange channels between the maintenance teams and data center. It consists of an operation and maintenance system platform located on the data center side and smart operation and maintenance boxes with mobile APP which are carried to the field side by the maintenance teams. As the kernel of the system, the smart boxes are bridges between the data center and operation sites. On one hand, it is able to formally upload data to the data center in real-time. One the other hand, the operation and maintenance personnel are able to call for help from the resource on the data center anytime. Using the system proposed in the paper, both efficiency of the operation and maintenance and the normalization of the data can be improved.

Unified monitoring and online maintenance technology of substation secondary equipment

“…Peng et al put forward a remote operation and maintenance architecture of substation monitoring systems based on the general service protocol of electric power systems, designed the application service interface and security control process of remote operation and maintenance, and initially realized remote operation and maintenance of substation monitoring systems [1]. Zheng et al studied a substation automation equipment operation and maintenance control system based on the universal service protocol of electric power and realized the functions of automatic periodic verification of data communication network shutdown, automatic generation of quarterly test reports, configuration control, and state evaluation strategy formulation [2]. Ye et al put forward the online status monitoring method of the IOP Publishing doi:10.1088/1742-6596/2814/1/012035 2 secondary circuit of relay protection device, abnormal sampling value, switching quantity monitoring, and abnormal early warning strategy, collected, analyzed, and uploaded the typical alarm information of the protection equipment and the secondary circuit faults through the network message recording and analyzing device or protection status monitoring and diagnosis device, to construct a set of online monitoring and fault diagnosis system of the secondary circuit of relay protection [3].…”

Networked Closed-Loop Model for Smart On-Site Maintenance of Substation Equipment Using Mobile Networks

“…In the previous work in [18], a Smart Operation and Maintenance (SOM) system has been presented focusing on the online management of the substation maintenance work, covering the hardware/software design, online system design, and also the online maintenance routines. In consideration of the development of NCS and the issues of power grid equipment maintenance such as the communication between management centre and the maintenance site, this paper proposes a networked model for on-site maintenance of substation equipment.…”
