常规的配电自动化系统通信电源短路故障在线检测方法容易受到多种因素影响,如电流波动、电磁干扰等,导致检测结果的准确性下降.同时,随着技术的不断发展,新的设备不断涌现,导致传统检测方法无法与新设备兼容,及时检测故障.因此,文章提出一种新的配电自动化系统通信电源短路故障在线检测方法,即分析通信电源短路故障特征,计算配电自动化通信电源短路故障潮流,从而完成通信电源短路故障在线检测.实验结果表明,设计方法检测的短路故障电流与实际短路故障电流一致,且测距准确,具有可靠性,满足通信电源的运行维护要求.
On-Line Detection Method of Short-Circuit Fault of Communication Power Supply in Power Distribution Automation System
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.
