Abstract

The invention provides a knowledge discovery method applicable to a power grid management system. The knowledge discovery method applicable to the power grid management system comprises the steps of selecting a decision event on which knowledge discovery is carried out, extracting data relevant to the decision event, converting the data relevant to the decision event into typical examples corresponding to a classification problem, training a decision tree classification model, and extracting knowledge corresponding to the decision event. According to the knowledge discovery method applicable to the power grid management system, implicit knowledge contained in the power grid management system is converted into explicit knowledge which can be analyzed by the system, and therefore the operation efficiency of a power system is improved and the integral intellectualization level of a power grid is improved.

Description

technical field [0001] The invention belongs to the technical field of power systems, and in particular relates to a knowledge discovery method suitable for a power grid management system. Background technique [0002] Smart grid is a major scientific and technological innovation in the power system in the 21st century, and the application of knowledge is one of the direct manifestations of grid intelligence. A large number of judgment logics and operating rules in the power system are solidified in the software and hardware systems, which reduces system flexibility and increases the cost of system update and maintenance. In the various production and operation management systems included in the power system, there are a large amount of basic knowledge of the power grid and expert experience knowledge, which cannot be accepted by the business application system in an effective and reasonable way, but exist in the documents in their own forms. or expert minds. If these know...
