Abstract

The invention provides a power distribution network equipment utilization rate detection method and device. Data synthesis is performed on the subjective weight of each detection parameter of the power distribution network equipment utilization rate so as to obtain the synthesized first weight of each detection parameter. Then data synthesis is performed on the first weight and the objective weight of each detection parameter so as to obtain the second weight of each detection parameter, and finally the detection value used for detecting the power distribution network equipment utilization rate is acquired according to the product of each detection parameter and the second weight of each detection parameter. Therefore, the influence of the subjective weight and the objective weight of eachdetection parameter is integrated in the obtained detection value used for detecting the power distribution network equipment utilization rate so that the power distribution network equipment utilization rate can be more scientifically and reasonably detected.

Description

technical field [0001] The invention relates to the field of distribution network operation detection, in particular to a method and device for detecting the utilization rate of distribution network equipment. Background technique [0002] The large-scale grid connection of distributed power generation will affect the utilization rate of distribution network equipment in many ways. On the one hand, the role of distributed power in sharing grid load, raising node voltage, and supplying reactive power reduces the backup capacity of the grid, which is conducive to improving the utilization rate of distribution network equipment. On the other hand, intermittent distributed power grid connection may cause the power flow direction to flow, resulting in longer system failure time, thereby reducing the utilization rate of distribution network equipment. The distribution network is directly connected to the end users, and the equipment is numerous and widely distributed. The level ...
