specific Embodiment approach
[0069] This embodiment comprises the following steps:
[0070] 1) When the transmission line fails, the data acquisition device samples the voltage and current signals at both ends of the line synchronously, and completes the alignment of the sampling data on both sides of the transmission line;
[0071] The methods of synchronous sampling of the voltage and current signals at both ends of the line by the data acquisition device are as follows:
[0072] The data acquisition devices at both ends of the transmission line carry out uninterrupted data acquisition of the voltage and current signals at both ends of the line;
[0073] The data acquisition device at both ends of the transmission line collects data on the line voltage and current signals when the transmission line is abnormal, and the data collected by the data acquisition device includes the data at the time before the fault;
[0074] The data acquisition device on one side of the transmission line collects data on t...
