| 摘 要： | 针对传统的电网局部放电定位方法的诸多缺点,提出了一种基于Sagnac干涉仪的光纤传感定位系统。该定位系统使用光纤作为传感单元,探测局部放电过程中所产生的声波和超声波,利用算法对探测到的振动信号进行处理,最终得到局部放电发生的具体位置。实验证明该系统具有较高的精确性和稳定性。

| Abstract: | To overcome the limitations of the traditional methods of monitoring partial discharge in the electrical network, this paper describes an all-fiber interferometer location system based on the Sagnac interferometer. By using the optical fiber as the sensing element to detect sonic and ultrasonic waves, the discharge signal is located. By means of the location algorithm, the location of the discharge can be determined. Experiment results show the high accuracy and stability of the system. |
