Research on Fault Detection Method of Ultra-High Voltage Direct Current Transmission Line Based on Optical Fiber Communication
With the wide application of ultra-high voltage direct current transmission technology,an efficient and reliable fault detection method for ultra-high voltage direct current transmission lines has become the key to ensure the safe and stable operation of the power grid.This paper proposes a fault detection method for ultra-high voltage direct current transmission lines based on optical fiber communication,which covers four links:data acquisition,signal processing,data transmission and fault diagnosis.The experimental results show that,compared with the traditional traveling wave method,the proposed method has significantly improved the fault detection rate,positioning accuracy and response time,which provides a strong guarantee for the safe operation of ultra-high voltage direct current transmission lines.
