Problems solved by technology

However, due to the different work experience and business ability of each regulator, different disposal results will be obtained for the same signal data, which will cause great problems to the safe and stable operation of the power grid.
On the other hand, the longer it takes to judge and deal with an accident, the longer the power grid runs in an abnormal operation mode, the greater the power loss, and the greater the possibility of further expansion of the accident.
The double pressure of accuracy and effectiveness in accident judgment and handling has brought great pressure to the work of regulators

Embodiment Construction

[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0051] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only and are not intended to represent the only embodiments.

[0052] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordi...

Abstract

The invention discloses a power grid accident abnormity analysis method and system based on a big data decision tree, and the method comprises the steps: obtaining power grid historical accident abnormity signal data and power grid historical monitoring data, carrying out cleaning, classification and other standardization processing, building a test sample set, setting all related attributes of power grid accident abnormity signals, calculating information gains of all related attributes in the test sample set, constructing a decision tree according to the information gains, and finally inputting to-be-analyzed power grid monitoring data into the decision tree to obtain a power grid accident abnormity analysis result. Therefore, causal connection between the power grid accident abnormity analysis result and the power grid monitoring data is realized through the decision tree, and compared with the prior art, the method has the advantages that intelligent analysis can be performed on the power grid accident abnormity based on the big data decision tree, so that the accident abnormity analysis result with high credibility and accident processing suggestions with good feasibility are displayed to monitoring personnel.

Description

technical field [0001] The invention relates to the technical field of electric power systems, in particular to a method and system for abnormal analysis of power grid accidents based on a big data decision tree. Background technique [0002] With the gradual optimization of the national grid management model, whether the grid regulators can timely and accurately judge the correctness of the accident signal and predict the power demand is a necessary requirement. However, due to the different work experience and business ability of each regulator, different processing results will be obtained for the same signal data, which will cause great problems to the safe and stable operation of the power grid. On the other hand, the longer it takes to judge and deal with an accident, the longer the power grid runs in an abnormal operation mode, the greater the power loss, and the greater the possibility of further expansion of the accident. The double pressure of accuracy and effecti...
