Abstract

The distribution transformer gear adjusting method based on comprehensive analysis and evaluation comprises the following steps: acquiring operation data of a distribution area and related data of a distribution transformer; establishing a comprehensive evaluation system index; establishing a distribution transformer gear adjustment optimization model; and optimizing the gear of the distribution transformer by using an NSGA-II algorithm based on a subjective and objective coupling weighting method to obtain an optimal adjusting instruction. The method not only considers the traditional voltage quality and equipment loss problems, but also introduces comprehensive indexes such as the utilization rate of the distribution transformer. Valuable information is extracted from a large amount of operation data, a related model is established through analysis and processing of historical data, and a multi-target optimization algorithm is utilized, so that the distribution transformer can give an optimal instruction for gear adjustment based on real-time data and multi-dimensional evaluation indexes.
