基于Arm Linux的电力调控设备工作状态检测装置研究与应用
|
摘要
电力调控自动化系统用于监视和控制电网运行,是电力调控业务的关键基础设施,也是电网安全运行的重要保障措施。随着投运时间的变长,其硬件设备时有故障发生,传统主要通过自动化巡检的工作方式,不能及时发现和解决设备故障和异常状态,给系统的稳定运行带来了极大风险。文章采用基于Arm微处理器的嵌入式Linux系统应用架构,利用光电传感器对可见光的敏感特性,结合硬件设备本身的异常告警信号指示灯,研究基于光传感技术和信息技术结合的电力调控设备工作状态检测装置,由该装置代替电力调度自动化值班员对相关硬件设备的工作状态进行24 h不间断在线监视,减少了值班员的非必要工作步骤,提高了电力调度值班效率。
Electric power dispatching and control automation system is used to monitor and control the operation of power grid. It is the key infrastructure for power dispatching businesses and an important safeguard for the safe operation of power grid. With the increase of operation time, the hardware failures occur from time to time. Traditionally, the failure and abnormal state of equipment can not be found and solved in time mainly through automatic patrol inspection, which brings great risks to the stable operation of the system. In this paper, an embedded Linux system application architecture based on ARM microprocessor is adopted. By utilizing the sensitivity of photoelectric sensor to visible light and combining with the abnormal warning signal indicator lamp of hardware equipment itself, the working state detection device of power control equipment based on the combination of optical sensor technology and information technology is studied. The device replaces the power dispatching automation attendant for the relevant hardware equipment. The 24-hour continuous on-line monitoring of the working state reduces the unnecessary working steps of the watchman and improves the efficiency of power dispatching on duty.
