Problems solved by technology

[0004] In order to overcome the above-mentioned background technology, the selection of the initial clustering center of different clustering algorithms is different, and the evaluation result of the operating state is largely related to the selection of the initial clustering center point. Not unique, there will be problems that the evaluation results of the low-voltage distribution network state are not unique and the accuracy is not high, and a method for evaluating the operating state of the low-voltage distribution network based on data mining is provided

Description

technical field [0001] The invention relates to the technical field of low-voltage distribution network operation and maintenance, and more specifically, to a method for evaluating the operating state of a low-voltage distribution network based on data mining. Background technique [0002] The distribution network is one of the important links of power transmission. As a link connecting the distribution network and the user side, the low-voltage distribution network plays a key role in power services such as power transmission and user response. The user side has an important impact. The operating state of the low-voltage distribution network directly affects the operating state of the power grid and the overall economic benefits, so the evaluation of the operating state of the low-voltage distribution network is particularly important. Existing state assessment technologies are mainly for medium and high voltage power grids. The commonly used methods include multi-source i...
