The invention discloses a power distribution network fault early warning method based on adaptive modeling analysis. The method comprises a step of obtaining the data information segment of the monitoring data in a predetermined system, analyzing the data information segment and obtaining each master key starting data, a step of counting corresponding predetermined parameter values according to each master key starting data, and calculating the fault warning value of the corresponding main key start data according to the predetermined parameter value, a step of comparing the fault warning value and each evaluation result preset range, and determining an evaluation result corresponding to the fault warning value, and a step of executing a corresponding operation according to the evaluation result. The method has the advantages of strong self adaptation and high accuracy. The invention also discloses a power distribution network fault early warning system based on adaptive modeling analysis, and the system has the above advantages.
Description
technical field [0001] The invention relates to the technical field of electrical engineering, in particular to a distribution network fault early warning system and method based on adaptive modeling analysis. Background technique [0002] With the rapid development of the economy, people have higher and higher requirements for the quality of power supply. The distribution network is at the end of the power system and is directly responsible for the power supply to users. Due to its complex line structure, the relationship between lines such as crossing, crossing, paralleling, and branching is gradually increasing. Inevitably. In order to improve the reliability of power supply for users, many studies have applied the fast recovery technology of distribution network faults to realize the restoration of power for users in time, but the research on the prevention of faults from the source through fault warning technology is less involved. [0003] Some existing technologies ...
