The invention discloses a power distribution network operation parameter key factor analysis method, system and device. The method comprises the steps of: constructing an operation parameter state matrix Y and an operation parameter influence quantity matrix X; constructing a key factor reference matrix and a key factor analysis matrix B; and respectively solving the characteristic value set [lambda] (B) of the key factor analysis matrix and the characteristic value set of the key factor reference matrix to calculate key indexes of all influence factors, constructing a key index sequence and selecting key factors. According to the embodiment of the invention, a key factor reference matrix and a key factor analysis matrix B are constructed through an operation parameter state matrix Y and an operation parameter influence quantity matrix X; according to the embodiment of the invention, the correlation between multiple factors and the operation parameters is analyzed based on the drivingof the operation parameters and the influence factor data, the limitation of a model analysis method is avoided, the correlation between the variable data and the target data can be accurately and quantitatively analyzed in a massive data environment, and the problem of deviation of correlation analysis is avoided.

Description

technical field [0001] The invention relates to the technical field of distribution network analysis, in particular to a method, system and equipment for analyzing key factors of distribution network operating parameters. Background technique [0002] In the actual operation of the distribution network, the operating parameters of the distribution network are affected by many factors, the main factors include: (1) Requirements for power supply reliability, when the proportion of important users is high, the power supply reliability is high, resulting in distribution Grid operating parameters are low. (2) For software and hardware facilities, if the grid structure is set unreasonably, or the technical level of equipment is low, the operating parameters of the distribution network will be reduced. (3) The quality problem of the equipment itself and the maintenance strategy of the equipment. Poor equipment quality and old problems will affect the utilization of the equipment, ...
