Problems solved by technology
[0003] The inventors found that the template formats and templates of the current power dispatching logs are various, and the types of faults recorded in different power dispatching logs are also different. The manual classification is a large amount of tasks, and the existing classification methods are not uniform due to the format. The classification speed is slow, and even key information is missed, resulting in inaccurate classification problems

The present invention provides a power dispatching log fault classification method and system. The method comprises the steps of: performing normalization of a format and a template of a power dispatching log; inquiring construction content in the power dispatching log, and extracting the construction position information as feature value information; inputting the extracted feature value information to a trained classifier; and outputting a fault classification result, wherein the classifier is generated based on a decision tree learning algorithm, and the training process of the classifier comprises: dividing the feature value information of the extracted normalized power dispatching log in the known fault type into a training set and a test set, and employing the training set to train the classifier until the precision of the classification result of the classifier is tested to achieve a preset requirement by the test set.
Description
technical field [0001] The disclosure belongs to the field of fault classification of power dispatching logs, and in particular relates to a method and system for classifying faults of power dispatching logs. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] The inventors found that the template formats and templates of the current power dispatching logs are various, and the types of faults recorded in different power dispatching logs are also different. The manual classification is a large amount of tasks, and the existing classification methods are not uniform due to the format. The classification speed is slow, and even key information is missed, resulting in inaccurate classification. Contents of the invention [0004] In order to solve the above problems, the first aspect of the present disclosure provides a fault classification met...
