摘要 当前的故障录波器终端受制于硬件平台,对换流站控制保护二次回路暂稳态大量数据的处理能力有限,单纯依靠软件算法提高分析准确率的空间有限,目前识别准确率无法达到可靠应用的要求。只有发生故障时,运维人员才会调取相应波形进行查看,对于大量监测波形,无法依靠人工识别出电气参量的微小变化,降低了运检人员的工作效率。本文提出一种基于AI边缘计算的监测数据实时分析预警系统,在故障录波器装置端配置AI加速模块,搭建换流站控制保护多源数据模型,采用统计分析和波形分析的多维数据处理算法,对换流站控制保护二次回路数据进行实时在线计算,以及时发现控制保护二次回路隐蔽性缺陷并预警。

Abstract:Due to the limitation of hardware platform, the current fault recorder terminal has limited ability to deal with a large amount of transient and steady data in the secondary circuit of converter station control and protection, and the possibility to improve the analysis accuracy rate only by software algorithm is limited. At present, the identification accuracy rate can not meet the requirement of reliable application. When there is a fault, the operation and maintenance personnel take the corresponding waveform to check, but for a large number of monitoring waveforms, it is impossible to identify the small changes of electrical parameters manually, which reduces the work efficiency of the operation and inspection personnel. In this paper, a real-time monitoring data analysis and early warning system based on AI edge calculation is proposed. The AI acceleration module is configured at the fault recorder device end, and the multi-source data model of converter station control and protection is built. The multi-dimensional data processing algorithm of statistical analysis and waveform analysis is used to calculate the real-time data of secondary circuit of control and protection of converter station, so as to discover the concealed defects of control and protection secondary circuit in time and warn early.
