Problems solved by technology

[0003] In order to solve the above problems, the present invention provides a high-performance processor-based fault recording and playback system and method based on multi-file sources. Aiming at the on-site fault recording file format, a corresponding recording file processing software is prepared, and multiple comtrade files of unlimited length Format data files are read in, processed and output in real time to realize the playback of fault recording, which solves the problem that the traditional recording file has a single source and cannot output multiple files at the same time; it has broad practical promotion and application value

Abstract

The invention provides a multi-file-source fault record replaying system and a method based on a high-performance processor. The system comprises a reading module used for reading each comtrade format data file and storing the data into a buffer area; a data processing module used for regarding GPS synchronizing signals as a synchronizing clock and performing corresponding processing of waveform data in the comtrade format data files according to the actual requirement; a transient waveform output module used for performing data-to-analog conversion of the waveform data and outputting waveforms via a waveform output channel; and a synchronizing signal trigger module used for triggering the modules to execute corresponding operation via the synchronizing signals. According to the system and the method, the waveforms of various files are read, and unified format adjustment and output can be realized according to the setting of user preconception.

Description

technical field [0001] The invention relates to a wave recording and playback system and method, in particular to a multi-file source fault recording and playback system and method based on a high-performance processor. Background technique [0002] With the increasingly complex operating conditions of the power grid, the control and protection technology of the power grid and the simulation test technology have been developed rapidly, so there is an increasing demand for technologies such as fault recording and playback, traveling wave devices, relay protection, and secondary device open-loop testing. urgent. Although the foreign real-time simulation program RTDS has similar functions, its wave recording and playback module can only read files in a specific format, and its capacity is limited, so it cannot output two files at the same time; there is no similar implementation in China. Contents of the invention [0003] In order to solve the above problems, the present in...
