Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0034] Such as figure 1 As shown, the information extraction method of the power grid dispatching plan includes the following steps:

[0035] Step 1, preprocessing the power grid dispatching plan.

[0036] The text of the power grid dispatching plan contains professional vocabulary. The general word segmentation method is to find the maximum segmentation combination based on word frequency by searching the maximum probability path. However, professional words with low word frequency will be filtered out when calculating the maximum probability path, so it needs to be analyzed. Preprocessing, as follows:

[0037] 11) Convert the power grid dispatching plan into plain text;

[0038] 12) Segmen...

Abstract

The invention discloses an information extraction method for a power grid dispatching plan. The method comprises the steps of performing word vector training on the power grid dispatching plan; performing power grid dispatching plan statement component analysis according to the word vector; and extracting information according to a statement component analysis result. The invention further discloses a corresponding system. According to the method, statement component analysis is carried out according to the word vectors of the power grid dispatching plan, information extraction is carried outaccording to statement component analysis results, the information extraction efficiency is high, the fault processing speed is increased, and the method is also suitable for unstructured plans.

Description

technical field [0001] The invention relates to an information extraction method and system for a power grid dispatching plan, belonging to the field of intelligent text information extraction. Background technique [0002] Due to the continuous expansion of the grid scale and the increasingly complex topology, the frequency of faults in the grid operation is also increasing. In order to effectively ensure the stable operation of the power grid system, when a fault occurs, it is necessary to quickly form disposal points according to the power grid dispatching plan for dispatchers to deal with in a timely manner. [0003] The power grid dispatching department has formulated the power grid dispatching plan manual based on the operation and maintenance experience. When a fault occurs, the dispatcher manually searches the plan manual, matches the fault type according to the characteristics of the event, and finds the corresponding handling points. In practical applications, rul...
