Simulator consists of a number of integrated products. With each new version we’ve continued to make Simulator more powerful and easier to use with the addition of a number of major new features and Simulator has the power for serious engineering analysis, but it is also so interactive and graphical that it can be used to explain power system operations to non-technical audiences. PowerWorld Ò Simulator (Simulator) is a power system simulation package designed from the ground up to be user-friendly and highly interactive.
