Abstract

An information recording method for electric power system fault expert diagnosis comprises the steps of defining a oscillograph window period, wherein the oscillograph window period comprises a detection recording period for oscillograph before a disturbance event occurs and a disturbance oscillograph period for oscillograph after the disturbance event occurs; carrying out dynamic annular oscillograph detection by adopting the detection wave recording period, and entering the next detection wave recording period if no disturbance event is detected in one detection oscillograph period; in one detection oscillograph period, if a disturbance event is detected, recording the disturbance event and an event occurrence moment, and entering the disturbance oscillograph period for oscillograph fromthe event occurrence moment; and in the disturbance oscillograph period, if it is detected that the disturbance event is ended, ending a oscillograph window period, storing oscillograph data and sending the oscillograph data to an analysis system. The information recording method is used for realizing oscillograph of fault expert diagnosis information.

Description

technical field [0001] The invention relates to the field of power system fault diagnosis, in particular to an information wave recording method for power system fault expert diagnosis. Background technique [0002] The power system is a system formed by connecting many power stations, substations, distribution stations and users with transmission and distribution lines. It usually consists of generators, transformers, busbars, transmission and distribution lines, and electrical equipment. Various electrical components, equipment and systems are usually in normal operating condition, but they may also experience faults or abnormal operating conditions. [0003] Power system failure refers to a state in which electrical components and equipment cannot work according to expected indicators, that is to say, electrical components and equipment do not achieve the functions they should achieve. Faults include generator set failures, transformer failures, transmission line failure...
