大型变电站分布式自动化检修系统设计

Design of Distributed Automatic Maintenance System for Large Substation

摘要:

由于大型变电站中的磁场对人们身体健康产生不利影响,因此通常采取分布式自动化检修系统对大型变电站进行检修;但目前大型变电站分布式自动化检修系统主要是通过给变电站中每一个相关设备安装状态检测信号,利用串口将设备运行状态数据传输到监控系统,监控系统根据运行状态数据判定变电站中各设备状态,并根据各设备的状态向串口发送命令,串口执行相应操作,从而完成自动化检修系统设计;但这种方法无法对变电站中需要检修的节点进行定位,导致变电站设备检修存在效率低的问题;为此,提出一种基于RSSI的大型变电站分布式自动化检修系统设计方法,首先对大型变电站分布式自动化检修系统的模块进行设计,并分析各模块功能,对大型变电站分布式自动化检修系统各模块电路进行设计,保证系统正常运行,在此基础上,利用RSSI算法对系统软件进行设计,保证系统能够准确及时的对故障节点进行检修,从而实现大型变电站分布式自动化检修系统设计,实验证明,所提方法设计的大型变电站分布式自动化检修系统能够准确对变电站中故障节点进行定位,保证检修的准确性和及时性,为该课题的研究开拓新道路,推动该领域发展。

Abstract:

Because the magnetic field existing in the large substation has a negative impact on people's health, it is necessary to send a large-scale substation to the substation magnetic field, which is not conducive to the health of the people. Therefore, the large-scale substation is usually carried out by distributed automatic maintenance system The But the current large-scale substation distributed automatic maintenance system is mainly through the substation in each of the relevant equipment to install the state detection signal, the use of serial port equipment to run the state data transmission to the monitoring system, monitoring system based on operational status data to determine the substation equipment in the state, And according to the status of each device to send commands to the serial port, the serial port to perform the corresponding operation, thus completing the automated maintenance system design, but this method can not need to repair the substation nodes in the substation, resulting in substation equipment problems identified low accuracy, In this paper, a design method of distributed automatic maintenance system for large-scale substation based on RSSI is proposed. Firstly, the module of distributed automatic maintenance system of large substation is designed and analyzed, and the functions of each module are analyzed. In order to realize the system modules, Distributed automatic maintenance system, the circuit is designed to ensure the normal operation of the system. On this basis, the RSSI algorithm is used to design the software of the system to ensure that the system can repair the fault nodes accurately and timely. This paper proves that the distributed automatic maintenance system designed by the method proposed in this paper can accurately locate the fault nodes in the substation and ensure the accuracy and timeliness of the maintenance. For the purpose of this project, the author analyzes the design of the large-scale substation distributed automatic maintenance system The study pioneered new ways and promoted the development of the field.
