Modeling Electrical Power Systems
SimPowerSystems provides libraries for modeling electric machines, transformers, and power converters. You can
connect components, such as generators, transmission lines, breakers, and motors, to model electrical power
systems. Application-specific libraries are also provided, enabling you to model electric drives, aircraft power
networks, and renewable energy systems. Connecting these systems with control systems modeled in Simulink lets
you test integrated electrical power systems in a single environment.
In addition to the traditional input-output or signal flow connections used in Simulink, SimPowerSystems uses
physical connections that permit the flow of power in any direction. Models of electrical power systems built using
physical connections (or acausal models) closely resemble the network they represent, and are easy to understand
and share.
You can define your three-phase connections using individual connections for each phase, enabling you to
perform tests such as injecting a single-line-to-ground fault. You can also create single-line diagrams, where the
three phases are represented by a single line, making the diagram easy to read. SimPowerSystems components are
parameterized using the per-unit system, which is widely used in the power system industry and simplifies the
parameterization and analysis of your system
