Abstract
The invention discloses a grid fault analytical method. The method comprises the following steps: step 1, obtaining power failure equipment information; step 2, obtaining switch motion information; step 3, acquiring protection action information; step 4, obtaining fault before and after operation modes; and step 5, obtaining a fault conclusion according to the information obtained in steps 1-4. The method is utilized to obtain the equipment fault information through step-by-step analysis, so that suspected factors are eliminated, equipment fault reasons are accurately judged, an effective solution is provided, and electric power can be conveniently and quickly recovered.
Description
Technical field
The present invention relates to the electric network fault analytical approach.
Background technology
Electric system has the characteristics of hierarchical structure, i.e. electric system is made up of factory station, circuit, and factory is made up of equipment such as switch, disconnecting link, bus, transformer, generator, capacitor, load circuits at the station.Factory constitutes network topology by line connecting relation between the station, constitutes factory's station topology with switch and plug-in strip annexation between the electrical equipment.In the prior art, the power system device failure analysis methods is wasted time and energy according to rules text and abstract scheduling experience, and the result is not accurate enough.After having an accident, report protection action situation and switch trip situation by operator on duty's phone of transformer station or subordinate's scheduling, and manually check the equipment failure situation to the trip device place.During the processing accident, also be according to the topological structure of the method for operation behind the power grid accident and electrical network and accident treatment rules etc., manually design feasible fault recovery scheme, and finish the grid switching operation of accident treatment by the mode that straighforward operation or phone are issued a notice.As seen, the mode of this manual analysis and processing accident is with power network safety operation and prevent that the requirement of large-area power-cuts from being incompatible.
