保护光电转换装置告警在线采集系统与保护通道故障自动分析定位方法研究

针对保护光电转换装置告警信息不能在线监测的问题，设计了基于树莓派的保护光电转换装置的在线采集系统。提出了综合利用采集到的保护光电转换装置告警信息与传输设备专业网管告警信息，对保护通道故障进行自动分析判断的流程。所提出的在线监测系统和故障自动分析判断流程，省去了现场查看保护光电转换装置告警的步骤，简化了保护和通信两专业人工协调分析的程序，对及早发现和定位故障区段，提升保护通道故障排查处理的智能化水平有积极意义。

Study on the alarm on-line acquisition system for protection photoelectric conversion device and automatic analysis and localization method for protection channel fault

Focused on the problem that the protection photoelectric conversion device alarm information can not be monitored on-line, the alarm acquisition system based on the Raspberry Pi is proposed for the protection photoelectric conversion device. The automatical analyzing and judging flow is proposed for the protection channel fault, which is based on the comprehensive analysis of the alarm information about protection photoelectric conversion device and professional network management system of the transmission equipment. Via the proposed on-line monitoring system and the fault automatic analysis and judgement procedure, the step of spot investigation of the alarm information for the protection photoelectric conversion device is saved, and the procedure of coordination and analysis by the two kinds of experts, including the communication and protection ones, is simplified. It has positive significance for detecting and locating the protection channel fault section early, improving the intelligent level of the protection channel fault searching and processing.
