Research On Remote Maintenance Of Power System Equipment

With the emergence of network inter-regional power systems, power system equipment showing a wide area, multi-point distribution maintenance. This has brought a lot of inconvenience to maintain and the power system development engineer. And specially, equipment maintenance software is causing a tremendous waste of human and material resources. So the remote maintenance of the power system equipment is required, the realization of power plants offered a convenient and efficient manner, saving time and maintenance costs and greatly reduced the maintenance workload for the substation equipment maintenance and development engineers. It is of great significance.First, the papers analyze the application of remote maintenance and find the focus of research: Device of maintenance. So the research explained the design of software and hardware. We choice AT91RM9200 as the CPU of the maintenance Device. After analyzing the features and process of AT91RM9200, the paper introduce the module circuit focus on the design of the communications module. In hardware design adopted a series of measures to strengthen the anti-jamming capability of hardware.The prominent feature of the software design is introduction of the embedded system, and the transplant and application of Embedded Real-Time Operating System(RTOS) Linux software and that improve the maintainability and reliability of the program and made it easier to achieve agreement on Ethernet TCP/IP communications. The article introduces the transplant of uCLinux operating system and the realization of TCP/IP protocol..Lastly, the article introduces the application of the maintenance device. It realizes the remote program upgrading of P89C51RD2. Remote Maintenance System can realize maintenance of broad area power system equipment. The system can be applied to the entire electricity system, it has some practical value.
