The invention discloses a method for analyzing the operating efficiency of a distribution network, which includes: establishing a direct influence matrix of each variable on the operating efficiency of the distribution network and a coupling degree matrix of each variable; calculating the normalized direct influence degree according to the direct influence degree matrix Matrix and the indirect influence standardization matrix of each variable on the operation efficiency of the distribution network are calculated according to the coupling degree matrix; the combined influence degree of each variable on the distribution network operation efficiency is obtained by calculating the normalization matrix of the direct influence degree and the indirect influence degree standardization matrix respectively ; Calculate the growth coefficient of each variable; According to the combined influence degree and growth coefficient of each variable, it is determined that the variable that meets the low efficiency condition is the cause of the low efficiency of the distribution network operation. This method is more scientific and reasonable, and can accurately determine the reasons for the low efficiency of distribution network operation. The present invention also provides an analysis system for operating efficiency of a distribution network and a computer-readable storage medium, both of which have the above-mentioned technical effects.
Description
technical field [0001] The present invention relates to the technical field of distribution networks, in particular to an analysis method for distribution network operation efficiency, and also relates to an analysis system for distribution network operation efficiency and a computer-readable storage medium. Background technique [0002] In the context of lean management, the distribution network big data platform is widely used to understand the utilization of single equipment and the overall asset operation efficiency of the distribution network by evaluating the operation efficiency of the distribution network. Based on the operating efficiency monitoring platform, low-efficiency equipment and weak areas can be discovered in time, and then the reasons for the low operating efficiency can be analyzed, so as to propose targeted improvement measures. [0003] The operating efficiency of the distribution network is easily affected by variables such as the "N-x" safety criteri...
