Abstract

Unlike short circuit faults in power systems, arcing faults produce intense light during the events. Light sensing technology has been developed as a part of arc faults detection since 1980’s. Currently, optical fiber and point sensors are 2 types of light sensors which have been applied along with simultaneous over-current mechanism for arc flash relays. Due to the characteristics of light sensors, sensitivity and reliability of the relay may be affected by the ambient light. This paper proposes a new approach for arc flash fault detection by using spectrum of the light. Electromagnetic radiation means different element would emit spectra with unique wavelengths when their atoms are excited. Therefore, elements can be identified if specific emission spectrum are detected during the excitation period. In general, Copper and Aluminum are commonly used for conductors. By examining the spectrum of the light, arc flash can be accurately and quickly detected. In the experiment of this study, copper and aluminum are applied as conductors. The light spectrum for both materials are measured and recorded by an optic spectrometer during the arcing incidents. The results show that accuracy and reliability of the light-based arc flash fault detection operation can be improved by using the proposed method.
基于光谱的高速电弧故障检测
与电力系统中的短路故障不同,电弧故障在发生过程中会产生强烈的光。自20世纪80年代以来,光传感技术作为电弧故障检测的一部分得到了发展。目前,光纤和点传感器是与同步过流机构一起应用于电弧闪光继电器的两种光传感器。由于光传感器的特性,继电器的灵敏度和可靠性可能会受到环境光的影响。提出了一种利用光的光谱进行电弧闪光故障检测的新方法。电磁辐射是指不同的元素在其原子受到激发时,会发射出具有独特波长的光谱。因此,如果在激发期间检测到特定的发射光谱,则可以识别元素。一般来说,铜和铝常用作导体。通过检查光的光谱,可以准确、快速地检测电弧闪光。在本研究的实验中,采用铜和铝作为导体。两种材料的光谱都是在电弧发生时用光谱仪测量和记录的。结果表明,该方法可提高基于光的电弧闪光故障检测操作的准确性和可靠性。
