Evaluation of Operation Modes of Distribution Transformers Base on K-means
In allusion to the problems of inaccurate evaluation results caused by the factors such as single evaluation indicator and incomplete evaluation process in the evaluation of operation modes of distribution transformers,the basic statistical indicators reflecting the historical load conditions of distribution transformers are analyzed.Starting from four different operation states of overload,heavy load,economic load,and light load,the K-means clustering algorithm is used for evaluation.The evaluation re-sults are filtered based on the silhouette coefficient,and 14 categories of operation modes of distribution transformers are identi-fied,providing the theoretical basis for improving the economy of distribution transformer operation.
