Abstract

The invention discloses a multi-information integrated power grid space-time multi-dimensional layer model construction method. The method comprises the following steps: analyzing power grid data; dividing the power grid data into three categories, namely a space layer, a physical layer and a data layer, and setting the three categories as power grid layers; creating a node and a relationship in each graph layer; creating a relationship among different graph layer nodes; storing a graph database and a relational database according to the data characteristics; updating the layer data along withthe time axis; carrying out layer calling and layered display in the power grid space-time multi-dimensional layer model according to requirements. According to the method, a power grid space-time multi-dimensional layer model construction process is explained, layers and internal relations are clearly divided, changes of the layers along with time are proposed, a layer database is introduced, and a system solution is provided for fusing data, geographic information and user information of all professional ports and achieving one graph of a power grid.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a multi-information-integrated spatio-temporal multi-dimensional layer model construction method of a power grid. Background technique [0002] The data volume of the power grid is huge, scattered in the dispatching system, marketing system, production management system, geographic information system, measurement automation system, as well as planning data, planning data, etc. From the perspective of the characteristics of the power grid, the power grid has the characteristics of a natural graph. With the topological connection relationship of the power grid as the link, the number of devices and users increases exponentially as the voltage level increases. With the development of big data and information technology, power grid enterprises are building power grid data platforms to conduct unified management of data such as transmission, transmission, transformation, distr...
