Three dimensional visualization and animation of travelling waves in power systems

This paper is concerned about the animation of power system transients for educational purposes. The electromagnetic transients programs simulate voltage signals at the line terminals only. These may not be sufficient to observe and understand the travelling wave phenomenon, which is of primary interest in most relaying and fault location studies. One way to capture the travelling waves is by animating the voltage profile along the studied line. This is accomplished by a new animation software, which is described in detail in this paper. Various visualization and animation methods are employed in order to bring out different features of voltage transients. Examples involving single-phase and three-phase power systems are given to illustrate the use of the developed tool.
