Fault Location of Fiber Optic Communication Channel in Relay Protection Based on Improved Bayesian Algorithm

传统的继电保护中光纤通信通道故障定位只能根据历史数据获取故障参数,导致故障定位精度不高,因此设计一种基于改进贝叶斯算法的继电保护中光纤通信通道故障定位方法。使用光功率计测量光纤通信通道的功率,获取光信号的强度信息。利用改进贝叶斯算法对故障信息进行处理,根据历史数据和实时数据,获取光纤通信通道的故障参数。根据故障参数,定位光纤通信通道的故障区域。实验结果表明,设计的基于改进贝叶斯算法的继电保护中光纤通信通道故障定位方法能够准确定位真实故障位置。

In conventional relay protection,the fault location of fiber optic communication channels can only obtain fault parameters based on historical data,resulting in low accuracy of fault location.Therefore a fault location method for fiber optic communication channels in relay protection based on improved Bayesian algorithm is designed.The method measures the power of fiber optic communication channels using an optical power meter to obtain information on the intensity of optical signals,uses improved Bayesian algorithm to process fault information,and obtains from historical and real-time data fault parameters of fiber optic communication channels,according to which the fault area of the fiber optic communication channel can be located.The experimental results show that the designed fault location method for fiber optic communication channels in relay protection based on improved Bayesian algorithm can accurately locate the true fault location.
