Abstract

The ongoing energy transition away from conventional energy generation to renewable energies demands for long distance connections with transmission lines and high energy cables. To reduce the risk of failures and outages the use of modern sensor and monitoring systems forces the implementation of fiber optic sensor systems. Fiber optic sensor systems are presented for the detection of acoustic partial discharges at cable connectors, switchgear and high energy transmission systems. Similar technology is used to assess the condition of circuit breaker. An additional application for photonic detection of partial discharges is shown too by the use of a photon sensitive fiber. Signal processing is applied for automated identification of defined patterns to separate partial discharges from noise for online monitoring as well as condition monitoring of circuit breaker based on acoustical analysis. All these modern techniques are presented for the use at energy transmission and distribution equipment.

光纤传感系统在传输系统和开关柜声光监测中的应用

正在进行的能源转型从传统能源发电到可再生能源，需要与输电线路和高能电缆进行长距离连接。为了降低故障和中断的风险，现代传感器和监控系统的使用迫使光纤传感器系统的实施。介绍了用于检测电缆接头、开关设备和高能传输系统的声学局部放电的光纤传感器系统。对断路器状态的评估也采用了类似的技术。通过使用光子敏感光纤，还显示了局部放电的光子检测的另一个应用。将信号处理应用于已定义模式的自动识别，将局部放电与噪声分离用于在线监测，以及基于声学分析的断路器状态监测。所有这些现代技术都是为输配电设备的应用而提出的。
