Research of Power System Time Domain Simulation Based on PSAT

The PSAT (Power System Analysis Toolbox) which is programmed using Matlab math language is introduced. It bases on graphical user interface and integrates with graphics collection,analysis,calculation and data management. A typical example of a time-domain simulation shows the establishment of the electricity network,model parameter settings,simulation graphics rendering and other key issues. Finally the right results are got. The results show that PSAT has a certain precision.
