The invention discloses a traveling wave ranging and fault wave recording integration device and implementation method. The device comprises a fault wave recording unit used for collecting an electricquantity, a non-electric quantity and a switching quantity when a fault occurs in an electric power system and performing wave recording, a traveling wave signal processing unit used for analyzing and judging a fault type of a traveling wave signal and calculating out a distance from the signal to a fault point through a time difference between time of arriving at devices at two ends by the signal, and an embedded system connected with the traveling wave signal processing unit for calculating the position of the fault point and connected with the fault wave recording unit for storing waveformdata during breakdown; and the embedded system further comprises a preset function interface which is used for providing data input or output. According to the device and the method, the problem of relatively low measurement precision and sampling frequency is solved; and accurate fault point positions can be obtained, and high-frequency transient waveforms can be recorded. The traveling wave ranging and fault wave recording integration device provided by the invention has the characteristics of being high in precision, high in reliability and the like.
Description
technical field [0001] The present application relates to the field of electric power, and in particular, relates to an integrated device for traveling wave ranging and fault recording and an implementation method. Background technique [0002] With the increasing scale of the power grid, as well as the increase of the transmission voltage level and the increase of the transmission distance, the grid structure is becoming more and more complex, and the possibility of failure will inevitably increase. The fault recording device that has been widely put into operation in recent years can quickly and accurately conduct a comprehensive analysis of transmission line faults, determine the type of fault, locate and eliminate fault points, and play a positive role, reducing losses caused by power outages and improving power consumption. The safety and reliability of system operation. At the same time, the conventional fault recording device also exposed some functional defects. ...
