The invention discloses a method for deducing a power system fault. A Bayesian network model is constructed based on a network topology structure before fault occurrence of a power system; the constructed Bayesian network is analyzed and processed according to fault information that is uploaded under the condition of fault occurrence of the power system; and then action information of protection devices corresponding to all elements under the condition of fault occurrence of the power system is obtained and thus deduction of the power system fault is realized. The Bayesian network model is anuncertainty causal relationship association model and has the powerful uncertainty problem processing capability; and multi-source information expression and fusion are carried out effectively and various uncertainty and incompleteness information can be processed, so that the fault tolerance capability is strong. Compared with the prior art with an expert system mechanism for deduction, the deducing method disclosed by the invention enables the fault deduction accuracy and efficiency to be improved. In addition, the invention also discloses an apparatus and equipment or deducing a power system fault and a readable storage medium that have the same effects.
Description
technical field [0001] The invention relates to the application field of power systems, in particular to a power system fault deduction method, device, equipment and readable storage medium. Background technique [0002] Power system fault deduction is to analyze the sequence of the fault information sent when a complex fault occurs, and combine the fault diagnosis results to deduce the action behavior of the secondary equipment and the state of the primary equipment. Through power system fault deduction, the recorded files of the accident can be used to replay, reflecting the actual operation status of the power grid within a period of time before and after the accident. Power grid dispatchers and operation and maintenance personnel can conveniently and effectively analyze the causes of accidents, adjust the operation mode of the power grid, avoid major accidents caused by misoperation, ensure the safe and economic operation of the power grid, and provide optimization and d...
