Problems solved by technology

[0003]In the existing dispatching system, the method of researching and judging the cause of the state switching of electrical objects is to use the method of manually inquiring about the scene and querying the dispatching log by telephone. This relatively primitive method The problems caused are: it is impossible to know the cause of the state switching event on the electrical object in time; it needs to spend a lot of energy and rely on experience for research and judgment

Abstract

The invention provides a status switching analytical method for electric objects in a scheduling system. The method comprises the following steps: acquiring abnormal information and operation information from a scheduling log system; according to serial numbers and belonged terminals, acquiring corresponding abnormal information or operation information of each electric object as key information of the electric object; according to the key information, acquiring a correlated event of each electric object; prestoring multiple keywords in a keyword and event correspondence library, labeling a corresponding event specific to each keyword, then specific to each correlated event, acquiring electric parameters of a corresponding electric object, and confirming whether the correlated vent is established according to the electric parameters.

Description

technical field [0001] The invention relates to the technical field of power grid monitoring, in particular to a method for analyzing state switching of electrical objects in a dispatching system. Background technique [0002] Dispatch production data is an important part of grid power quality system monitoring. The power data integrated by the system from the dispatch technical support system mainly includes grid frequency, grid voltage, grid equipment ledger, and power transmission and transformation equipment switching and other related information. Accurately judging the time and equipment of dispatching power transmission and transformation equipment state switching events can reflect the operating status of a certain regional power grid, provide sufficient support for fault finding, analysis and fault isolation, and further improve the quality of power grid data. [0003] In the existing dispatching system, the research and judgment of the cause of the state switching ...
