Abstract

The invention provides a multi-dimensional space-time thematic display method and system for a power grid, and the method comprises the steps: taking a line where a plant station is located and a power supply zone as a curve and a curved surface of a link critical point, extracting a selected topological structure, and carrying out the visual display of spatial data according to a topological visualization method; and performing association display on the time sequence change of the fault equipment and the time sequence data comprehensive analysis result of the power supply partition where the fault equipment is located by using a time mark data processing function. According to the method, the spatial data topology of the power grid of the fault equipment can be visualized, the time sequence change of the fault equipment is displayed in an associated manner, the real-time situation of the power grid is displayed integrally and locally in all directions, and the method can be applied to the tidal current diagram display process.

Description

technical field [0001] The invention belongs to the field of grid dispatching automation of electric power systems, and in particular relates to a multi-dimensional spatio-temporal themed display method of a grid. Background technique [0002] At present, in the smart grid dispatching control system, the grid power flow diagram can display the overall operation information of the grid in the spatial dimension, but it cannot partially display the spatio-temporal data of the faulty equipment at the same time. Grid operation screens are predefined based on experience. Power grid dispatchers can view power grid operation information in spatial dimensions such as power system plant location information, plant station and line status through power flow graphs, or view grid operation information in time dimensions such as the entire network load through graphs. Grid dispatchers cannot view the associated grid space-time information, and cannot directly obtain the timing changes of...
