Abstract

The invention discloses a wave-recording data transmission method, device and system. The method comprises: after a line occurs a fault, a wave-recording device acquires sampling data within a preset time; the wave-recording device obtains wave-recording data according to the sampling data based on the preset general standard, wherein the wave-recording data comprises a head file and a data file; and after receiving a data request sent by a master station, the wave-recording device sends the wave-recording data to the master station, wherein the master station processes the wave-recording data and obtains a processing result. According to the wave-recording data transmission method, device and system, a technical problem that the wave-recording data transmission method in the prior art does not utilize the industry general standard is solved.

Description

technical field [0001] The invention relates to the field of fault wave recording standards, in particular to a transmission method, device and system for wave recording data. Background technique [0002] Distribution network automation is an important part of smart grid, and distribution network fault handling is the core content of distribution automation. Regardless of whether it is fault location and determination, or subsequent fault analysis and fault recall, device fault recording is of great significance. [0003] The wave recording data of the device is stored in the device, and must be sent to the main station system or wave recording analysis software through the network or wireless GPRS to realize line fault location and fault analysis. Especially for the judgment of fault location, it is necessary to transmit the recorded wave data quickly and reliably. Otherwise, the failure or error of fault location will expand the scope of power outage and reduce the reli...
