The invention discloses a method and a device for determining a power system fault. The method comprises the following steps of: collecting the state parameters of a plurality of electric signal types in a power system; according to the state parameters of the plurality of electric signal types, judging whether the state parameters of the plurality of electric signal types meet preset conditions or not; and when the state parameters of the plurality of electric signal types meet the preset conditions, determining whether the state parameters of the plurality of electric signal types meet a preset association rule, and if the state parameters meet the preset association rule, determining that the power system has a fault. According to the method and the device, the technical problems of inaccurate judgment result and misjudgment caused by judging the working state of the power system based on a single state parameter in the prior art are solved.
Description
Technical field[0001]The present application relates to the field of electricity, and in particular, a method and apparatus for determining a failure of a power system.Background technique[0002]Traditional Internet of Things Monitoring terminals have a single state parameter monitoring function, which can monitor the operating state of the low voltage power system in real time and report to the primary station system. However, for the depth calculation of state parameters and integrated analysis of various monitoring parameters usually needs to be implemented in the platform layer, which causes the uploaded data amount to be too large, so that the data processing amount of the platform is overloaded, so that it has insufficient computational power, etc. Question, that is, the lack of integrated use of multiple monitoring parameters for multi-dimensional comprehensive analysis, if the single monitoring terminal is fails, the method of using a single data assessment is easy to acciden...
