The conventional online detection method for communication power short circuit faults in distribution automation systems is easily affected by various factors,such as current fluctuations,electromagnetic interference,etc.,which can lead to a decrease in the accuracy of the detection results.Meanwhile,with the continuous development of technology and the emergence of new devices,traditional detection methods are unable to be compatible with new devices and detect faults in a timely manner.Therefore,the article proposes a new online detection method for communication power short circuit faults in distribution automation systems,which analyzes the characteristics of communication power short circuit faults,calculates the flow of communication power short circuit faults in distribution automation,and completes online detection of communication power short circuit faults.The experimental results show that the short-circuit fault current detected by the design method is consistent with the actual short-circuit fault current,and the distance measurement is accurate,reliable,and meets the operation and maintenance requirements of communication power supply.
