Modeling Electrical Power Systems

With SimPowerSystems, you build a model of a system just as you would assemble a physical system. The components in your model are connected by physical connections that represent ideal conduction paths. This approach lets you describe the physical structure of the system rather than deriving and implementing the equations for the system. From your model, which closely resembles a schematic, SimPowerSystems automatically constructs the differential algebraic equations (DAEs) that characterize the behavior of the system. These equations are integrated with the rest of the Simulink model.

You can use the sensor blocks in SimPowerSystems to measure current and voltage in your power network, and you can then pass these signals into standard Simulink blocks. Source blocks enable Simulink signals to assign values to the electrical variables current and voltage. Sensor and source blocks let you connect a control algorithm developed in Simulink to a SimPowerSystems network.
