Abstract

An electric power system fault diagnosis method based on topological analysis comprises the steps that topological binding of a power grid is carried out on measuring point information of an electricpower system, so that the measuring point information has topological properties; acquiring measuring point information when the power system runs as first information, and judging whether a disturbance event occurs or not according to the first information; when a disturbance event occurs, extracting the first information used for judging the occurrence of the disturbance event as second information; determining a topological domain for fault diagnosis search according to the topological property corresponding to the second information; and in the topological domain, correlation analysis of the second information is realized, and a fault point or a fault range is determined. According to the power system fault diagnosis method, the fault position can be accurately determined in real timethrough the determination and use of the topological domain, so that corresponding fault processing can be carried out more efficiently.

Description

technical field [0001] The invention relates to the field of power system fault diagnosis, in particular to a power system fault diagnosis method based on topology analysis. 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 failures, Substati...
