A new tool for computing and visualizing the operation of power system components and systems is presented. One component of the tool is a time domain simulator that operates in the background within a multitasking environment. Visualization and animation objects can retrieve data in real time from the time domain simulator and display a detailed picture of a component or system operation. As the system state evolves, the pictures are updated resulting in an animated visualization of the process. The tool has been implemented in a multitasking environment, thus permitting user interaction in real time with the system parameters and immediate reflection of the results in animations and visualizations. Several examples of visualization and animation are presented, including animation of Mho relay operation, visualization of small signal stability, load dynamics and voltage sensitivity and synchronous machine operation.
