The invention relates to a method and device for quickly positioning a fault of a converter valve control system, computer equipment and a storage medium. According to the method, a fault recording file sent by control equipment is received, fault related information in the fault recording file is periodically scanned, and change information is analyzed to determine fault information, wherein the fault recording file is a fault recording file generated when the control equipment detects any one of a fault of a self-checking type, a fault of a tripping type and a fault of a power module type. According to the method, the fault recording file is automatically analyzed, so that the fault in the converter valve control system is automatically positioned, and the problems of low efficiency and low accuracy caused by manual fault positioning are solved. In addition, the method also realizes fault positioning of a self-checking type fault, a tripping type fault and a power module type fault, and compared with a traditional single fault positioning method, the diversity of faults which can be positioned is improved.
Description
technical field [0001] The present application relates to the technical field of high-pressure converter valve control systems, in particular to a method for quickly locating faults in the converter valve control system. Background technique [0002] In the field of electric power control, high-voltage converter valves are important equipment in DC transmission converter stations. Thousands of power modules are connected in series to realize voltage division and AC-DC conversion. Therefore, it is necessary to monitor and control each power module of the HVDC converter station, analyze the cause of the failure in time, and ensure the normal operation of the converter station. [0003] At present, the converter valve control system is generally used to monitor each power module of the high-pressure converter valve in real time, and the monitoring data in each time period is obtained, and then the maintenance personnel manually obtain the monitoring data from the converter valv...
