Abstract

The invention discloses a power grid fault tracking method based on data mining technology. The method includes taking various types of data acquisition systems of an intelligent substation as an original data source; selecting a decision tree to classify the information in the station, and providing decision support for the fault tracking program on a dispatching side; classifying the data filtered by the decision tree according to the supervision model into three classes: protection rejection signals, signal channel fault signals, and breaker rejection signals; and after the classification algorithm of the decision tree on the training samples is completed, predicting the data set in the unknown class, and corresponding to the power grid fault tracking process, namely, analyzing the various kinds of data of the transformer station layer to give the protection or breaker rejection reasons. The power grid fault tracking method can monitor the other data of the lower transformer station layer at the dispatching center, for example, the general level and forecasting level alarm data, can determine the condition of protection and breaker rejection according to the data, timely know the condition of the power system, and saves time for the power grid fault self-healing.

Description

technical field [0001] The invention relates to the technical field of grid faults, in particular to a grid fault tracking method based on data mining technology. Background technique [0002] Judging from the current research results of fault diagnosis algorithms, the analysis of faulty components will be very accurate under the premise that both the protection and the circuit breaker operate correctly. However, when the protection or circuit breaker refuses to operate, many diagnostic algorithms only judge that there is a failure to operate based on the action of the remote backup, and cannot deduce whether it is the protection or the circuit breaker that refuses to operate, let alone the failure to operate. Cause fault tracing. [0003] The meaning of power grid fault tracking in the present invention means that after the dispatching terminal invokes the fault diagnosis algorithm for the collected alarm information, it is found that there are incorrect actions of circuit...
