Abstract

The invention discloses a graph visualization system used for electric system load flow and stability analysis. The graph visualization system comprises a data processing module, a topological analysis module, a parameter modifying module, a graph displaying module and a software interface module. The data processing module is used for obtaining, storing and exporting network topological data, and a calculation file and the topological data are connected in a linkage mode. On the basis of data processing, the system sets the starting and halting states of equipment, and modifies parameters of the equipment through the topological analysis module and the parameter modifying module. Programs, provided by PSD-BPA software, for load flow calculation, stability calculation, N-1 analysis, small interference, short-circuit currents and fracture surface limit analysis are called through the software interface module. The graph displaying module is used for displaying a power grid topological structure, editing graph objects and displaying calculation result information. According to the system, power grid equipment parameters and mode data are adjusted on a graph sheet, the load flow and stability analysis is performed on the graph sheet, the management mode of text data is changed, and manufacturing efficiency of a power grid calculation mode is improved.
