针对配电变压器运行方式评价过程中评价指标单一、评价过程不全面等因素造成的评价结果不准确的问题,分析了反映配电变压器历史负载情况的基本统计指标,从过载、重载、经济、轻载4种不同的运行状态着手,采用K-means聚类算法进行评价,结合轮廓系数对评价结果进行筛选,得出了配电变压器的14类运行方式,为提高配电变压器运行的经济性提供了理论依据.
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.
