摘要(Abstract):
提出了一种全频域暂态信息记录及分析系统的架构体系,并介绍了相关装置研发情况。该系统利用基于隧道磁电阻效应的宽频带传感器,可满足10 Hz~5 MHz范围内故障暂态电流的宽频带采样,全频域录波器可支撑高达10 MHz的暂态触发录波。基于该系统可实现电网暂态信息大数据的记录与分析,有助于揭示设备故障、局部放电和雷电等暂态过程的时频特征,实现系统不同类型暂态扰动的快速检测与识别,支撑主动式预保护技术的发展。
This paper proposes an architecture of recording and analysis system for full frequency domain transient information in power system and introduces its research and development. The system utilizes wideband sensor based on the tunnel magnetoresistance effect(TMR) for wideband sampling of transient current with the frequency from 10 Hz to 5 MHz, and the full frequency domain recorder is up to 10 MHz. Based on this system, the transient information big-data in the power system can be recorded and analyzed. This system can help disclose the time-frequency characteristics of the transient process such as the equipment fault, partial discharge and lightening to detect and identify different transient disturbances and support the development of the proactive protection technology.
