SimPowerSystems was designed to provide a modern design tool that allows
scientists and engineers to rapidly and easily build models that simulate power
systems. SimPowerSystems uses the Simulink environment, allowing you to
build a model using simple click and drag procedures. Not only can you draw
the circuit topology rapidly, but your analysis of the circuit can include its
interactions with mechanical, thermal, control, and other disciplines. This is
possible because all the electrical parts of the simulation interact with the
extensive Simulink modeling library. Since Simulink uses MATLAB® as its
computational engine, designers can also use MATLAB toolboxes and
Simulink blocksets. SimPowerSystems and SimMechanics share a special
Physical Modeling block and connection line interface
