Embodiment 1
[0035] The present invention provides a data mining method for power grid operation mode based on CART decision tree, and its implementation process is as follows figure 1 shown, including the following steps:
[0036] Step S101, extracting data related to the operation mode of the power grid.
[0037] During the operation of the power grid, the data related to the operation mode of the power grid include: the name of each power equipment (such as transformers, generators, transmission lines, etc.), the connection relationship between power equipment; the operation status of power equipment (including "operation", "standby" and "maintenance) and so on; these data related to the operation mode of the power grid are collected by the automatic terminal equipment and transmitted to the server.
[0038] Step S102, preprocessing the extracted data related to the operation mode of the power grid to obtain real data.
[0039] After the data is extracted, the data needs to be preproc...
Embodiment 2
[0052]The present invention also provides a power grid operation mode data mining system based on a CART decision tree, which includes: a data acquisition unit 11, a preprocessing unit 12, a CART decision tree construction unit 13, a scheduling data operation mode scheme formation unit 14, and an evaluation unit 15 .
[0053] The data acquisition unit 11 is used to extract data related to the grid operation mode;
[0054] The preprocessing unit 12 is used to preprocess the extracted grid operation mode related data to obtain real data;
[0055] The CART decision tree construction unit 13 is used to construct a CART decision tree based on real data; the specific processing is the same as the related description in Embodiment 1, and will not be described in detail here.
[0056] The scheduling data operation mode scheme forming unit 14 is used to traverse the nodes on the CART decision tree according to user requirements, and call the real data in the corresponding address acco...

Abstract
The invention relates to a power grid operation mode data mining method and system based on a CART decision-making tree. The power grid operation mode data mining method comprises the following steps: extracting relevant data of a power grid operation mode; pre-processing the extracted relevant data of the power grid operation mode to obtain real data; based on the real data, constructing the CART decision-making tree; traversing nodes on the CART decision-making tree according to user requirements, and calling the real data in corresponding addresses according to variables corresponding to the nodes so as to form new dispatching data operation mode schemes; and selecting an optimal dispatching data operation mode scheme from all the dispatching data operation mode schemes according to economic index evaluation. According to the power grid operation mode data mining method and system provided by the invention, the data dispersed in all subsystems can be integrated so that manual operation amount and time can be reduced; manual intervention on the data is eliminated; and load conditions of all regions, transformer substations, transformers and the like can be predicated in classes, and the formulation of a power grid operation mode analysis report is assisted.
Description
technical field [0001] The invention relates to the field of ships, in particular to a CART decision tree-based power grid operation mode data mining technology. Background technique [0002] With the rapid development of the power system dispatching automation system, the automation terminal collects a large amount of data such as the operating status of equipment and components, and the connection mode of the neutral point, and the amount of data is increasing at a double rate, and the capacity of the database has reached At the level of trillions of bytes, these data are largely redundant data idle in the database. Behind these large amounts of data hide a lot of decision-making information. If you want to analyze these seemingly "useless" "It is particularly important to query, retrieve, extract and convert data into useful auxiliary decision-making information. Contents of the invention [0003] The purpose of the present invention is to provide a data mining method ...
