Embodiment 1

[0035] The present invention provides a multi-dimensional management method for power grid simulation calculation data, the flow chart of which is as follows Figure 5 As shown, it includes two steps of data storage and data service.

[0036] With the formation of cross-regional interconnected grids and the continuous expansion of scale, the data scale of grid simulation analysis and calculation has also doubled, and the requirements for data storage and management on space and efficiency are also increasing. The purpose of multi-dimensional grid data management is to Data storage avoids the storage of repeated data in space, improves the query efficiency of data, and establishes a data foundation for solving changes in power grid data, application calculation and analysis results, change records and corresponding relationships between power grid operating characteristics.

[0037] Data storage is based on three types of data storage: grid structure data, equipment parameter d...

Embodiment 2

[0053] Based on the same idea, the present invention also provides a multi-dimensional management system for power grid simulation calculation data, including:

[0054] Data storage module: used to realize three types of data storage according to grid structure data, equipment parameter data and operation mode data; the grid structure data refers to the grid structure of a certain branch or a certain province within a certain period of time; Equipment parameter data refers to the parameters of various equipment connected to the power grid; operation mode data refers to the connection form and status of various equipment in the system;

[0055] Data merging module: used to provide customers with the required data services. Data merging finds the corresponding basic dimensional data and corresponding changed data according to user needs to complete data superposition, that is, the changed data covers the basic dimensional data to form the final data;

[0056] Data service module...

Embodiment 3

[0060] Taking Heilongjiang users as an example to carry out calculation work on the 2014 summer mode data, users obtain the data required for calculation through data services.

[0061] The following data is stored in the data pool:

[0062] The grid data of Heilongjiang Province in 2014 is used as the basic data, v1.0, which is the basic dimension data;

[0063] The change data corresponding to the summer mode; v-summer-max

[0064] The change data corresponding to the summer minor mode; v-summer-min;

[0065] The change data corresponding to the major mode in winter; v-winter-max;

[0066] The change data corresponding to the small mode in winter; v-winter-min;

[0067] The section data v-201401010910 corresponds to the data at 9:10 on January 1, 2014; the section data will form a new set of section data every 15 minutes; the data storage diagram of Heilongjiang Province is as follows figure 1 shown.

[0068] The upper-level data of Heilongjiang Province and the data st...

Description

technical field [0001] The invention relates to a large data management method for grid calculation and simulation analysis in the field of electric power systems, in particular to a multi-dimensional management method and system for grid simulation calculation data. Background technique [0002] The usual power grid (simulation) data is very large and complex. Different calculations and analyzes have different data ranges and usage requirements; while the basic data of the power grid, the basic facility configuration data, has multiple dynamic and static characteristics. The configuration changes of power grid facilities brought about by different operation modes have a huge impact on power grid analysis and calculation. Therefore, changes in power grid data, power grid (calculation / simulation) data, etc. affect, manage and serve, and are the key to power grid analysis, calculation, and operation management. The most critical factor for the effectiveness of theories and me...
