Problems solved by technology

However, due to the differences in the habits of different dispatchers when recording logs, and the rich and colorful Chinese language, it is often difficult to automatically identify the specific type of fault from the log after recording the log, which is not conducive to the statistical data of faults. Making Reasonable Power Grid Dispatching and Maintenance Decisions

Embodiment Construction

[0050] The present invention is further described by the present invention, but the present invention is not limited to the following detailed description.

[0051] A power scheduling log fault classification method,

[0052] (1) First, the M-Power Dispatching log is first collected. According to the log content, the type of fault is labeled. The line fault is marked as 1. The transformer fault is marked as 2, and the bus bar fault is marked as 3, and the four-small fault marks as 4, labeling other faults as 5, forming training sets, including five training sets, as shown in Table 1 below:

[0053] Table 1

[0054]

[0055]

[0056] (2), pretreatment of the above test logs, the unimplement punctuation, such as quotation marks ", wavy ~, etc., convert the unregulated words, and divide the pre-processed log Multiple words,

[0057] (3) Generate the D = 100 of each single word using the Word2VEC tool, and this particular embodiment will take D = 100, for example:

Abstract

The present invention relates to the field of power dispatch, in particular to a method for classifying faults in a power dispatch log. A support vector machine model is obtained mainly through multiple training logs, and then the power dispatch log can be classified according to the obtained support vector machine model. In this way, the accuracy rate is high, and with the support vector machine model, the log obtained later can be processed and input into the model, that is, the fault type in the power dispatch log can be easily identified.

Description

Technical field [0001] The present invention relates to the field of electricity scheduling, and more particularly to a power scheduling log fault classification method. Background technique [0002] In the current grid, the species of the equipment is numerous. When the equipment failure occurs, the dispatched personnel often use the natural language to record the failed factory station, interval, equipment, voltage grade, fault occurrence phenomenon, cause cause, etc. in the scheduling log. . However, since different schedulers have different habits when recording the logs, coupled with the Chinese language colorful, often leading to the record log, it is difficult to automatically identify the specific category of the fault from the log, which is not conducive to statistics according to the fault. Develop a reasonable grid scheduling and overhaul decision. Inventive content [0003] The technical problem to be solved by the present invention is to provide a power scheduling l...
