Abstract

The invention relates to an automatic recording method for abnormality of time synchronization signals. The time synchronization signal is collected by a time synchronization signal collection circuit, and converted into digital signals by an analog-digital conversion module, so as to realize the collection of real signal waveforms. Then, the collected time signal waveform is analyzed by the application layer analysis software. If some of the parameter indicators exceed the set range, the corresponding time signal waveform in a period of time before and after the moment is stored and recorded. After the time synchronization signal of the invention passes through the acquisition circuit, the output signal is a digital sampling value, and the waveform of the time synchronization signal can be truly reproduced; the signal analysis of the real time synchronization signal waveform is performed, and the analysis result is accurate, and the level information and the level information in the signal can be accurately obtained. Rising edge related parameter indicators, abnormal judgment is accurate; it also automatically records and stores the time synchronization signal waveform when the abnormality occurs, saving equipment storage space and facilitating later search and analysis.

Description

technical field [0001] The invention relates to a method for automatically recording abnormalities of time synchronization signals, which belongs to the field of electric power system automation. Background technique [0002] With the rapid development of the power system, the requirement for time synchronization is becoming increasingly urgent. Accurate, safe and reliable clock sources are needed to provide accurate time references for various equipment in the power system, so as to ensure the consistency of real-time data collection time and improve power grid accident analysis and monitoring. Stabilize the control level and improve the efficiency and reliability of power grid operation. Therefore, the power system has formulated corresponding time synchronization standards, defining physical interfaces, data interfaces, system components, and accuracy. [0003] The types of time synchronization signals output by the clock source include pulse signals, IRIG-B codes, and s...
