Abstract

The invention provides a distribution transformer classification method based on fuzzy clustering. The invention discloses a distribution transformer classification method based on fuzzy clustering, and the method comprises the following steps: S1, obtaining the monthly average load rate maximum value of each distribution transformer, and recording the maximum value as 1, 2,..., lambdam as the number of the distribution transformers; S2, dividing the distribution transformer of which the monthly average load rate maximum value is greater than or equal to 80% into heavy-load transformers, and recording the number of the heavy-load transformers as m1; The distribution transformer with the monthly average load rate maximum value smaller than or equal to 20% is divided into light-load transformers, and the number of the light-load transformers is recorded as m2; And S3, for the distribution transformer with the monthly average load rate maximum value greater than 20% and less than 80%, dividing the distribution transformer into three types by using a fuzzy clustering method, namely a constant-load type I transformer, a constant-load type II transformer and a constant-load type III transformer. Based on the advantages of fuzzy clustering, transformers except the light-load transformer and the heavy-load transformer are classified so as to adapt to the requirements of differential planning, and meanwhile the thinking modes of people can be better met.

Description

Technical field [0001] The present invention relates to the technical field of distribution network planning, and more specifically, to a classification method of distribution transformers based on fuzzy clustering. Background technique [0002] Distribution transformer is an important electrical equipment in the distribution network, and it is also an important object in the distribution network planning. In order to meet the requirements of differentiated planning, transformers need to be classified. In the process of transformer operation, the load factor is an important indicator, and it is reasonable to classify the transformer according to the load factor. [0003] At present, according to the method of classifying transformers based on load factor, light-load transformers and heavy-duty transformers have clear defined values, and the rest are not classified in detail, which is not conducive to the development of differentiated planning. Summary of the invention [0004] In ...
