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.
Highlights
Power grid equipment maintenance is an important part of the management for power generation and transmission
On the base of the latest mobile Internet technology and big data technology, this paper proposes an online intelligent operation and maintenance system based on mobile network
In order to address these problems, the on-site smart operation maintenance system for substation equipment is developed based on new information and communication technologies
Summary
Power grid equipment maintenance is an important part of the management for power generation and transmission. Substations’ daily work have been gradually divided into operations and maintenance according to the responsibilities[1] This division of labor plays an important role in the professional development of the business, and in ensuring the safety of power grids in China. The dispersion of power grid equipment and the disconnection between the field side and the center side leads to that the operation and maintenance work cannot efficiently and effectively use the central side of resources. They can use the rich resources to complete the operation maintenance task It can improve the efficiency of on-site operation, provide a system support for the application of new information technology in on-site application and control, and strengthen the remote control and real-time technical support ability of on-site operation and maintenance
