What is PowerWorld Viewer?
PowerWorld Viewer is a free software package that we developed so that our customers could provide their results from Simulator to whomever they wish. As the name implies, Viewer allows users to view a case with all the ease of Simulator, including all the animation features. However users of Viewer can not modify the case in any way. You can download a free version of Viewer, capable of viewing systems with up to 100,000 buses.
