Substation Equipment

The maintenance of substations is crucial for the safety of the electrical grid and power industry.<strong> </strong>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.

To adapt to the changing requirement of task data interface under the situation of far distance, multiple segment, multiple circle, multiple satellite and multi-station visibility for satellite misson in transfer orbit segment, the web incremental maintenance system based on materialized view was achieved through applying incremental maintenance principle, database technology, synchronization mechanism and maintenance proxy, and realizing the synchronization and consistency of data interface about the distributed experiment information surveillance software system. The result shows that web incremental maintenance system can ensure the real-time and consistency of data processing and transmission.

Equipment management is one of the key factors of coal mining safe-production, the traditional equipment management methods can no longer meet the real-time and automation needs of modern management. Based on fault diagnosis, sensor network and wireless communication technology, this article proposes a new modern equipment spot-inspection maintenance (ESIM) system for coal mining, and further explains the three-level logical model and construction method of it. The ESIM can achieve the requirements of real-time monitoring, automation control and intelligent analysis, which helps improve scientific management of coal equipment.
