Version 1.0
The MathWorks Simscape Team has developed a support library for Simscape Electrical that contains component assemblies and parameterization options more familiar to the power systems engineering community, in a readily accessible format, for use with Simscape Native Technology. The library also contains links to relevant Simscape Electrical shipping libraries for ease of navigation. For each assembled component, you can view the mask code for further detail on parameterizations and use of the Simulink API to interact with Simscape components. The Support Library comes with a number of examples that are described later in this document. The library organizes different component classifications as 8 sub-libraries, as shown below.
The Electromechanical Machines sub-library is shown below. The assemblies are contained within the blue area and the links to Simscape Electrical shipping libraries are contained within the yellow area.
The image below shows the Round Rotor Standard (PU) assembly.
Each assembly has a parameter mask which exposes relevant parameters. Where applicable, there is also a check-box option to set all mask parameters as run-time, meaning the model will not recompile if any of the mask parameters change when using Fast Restart mode, or when the model is compiled as a MEX file.
The support library comes with four sub-directories under examples.
examples/1.component_tests contains test harnesses for a number of components within the Support Library.
examples/2.motor_drive contains a PMSM driven by an MMC converter. Each cell of the MMC has an ideal voltage source to simplify the control system. There are 96 individual switches in the MMC. open a0_README.mlx for further instructions. This example also considers the performance advantage of using simplified diode models that fix forward voltage at 0V.
examples/3.power_system contains a power systems example that uses MATPOWER to run a load flow of a 30 bus system and then programmatically builds and simulates an EMT model. Navigate to the workflows directory and open a0_README.mlx for further instructions. MATPOWER is a MATLAB Community Toolbox available at the following link https://www.mathworks.com/matlabcentral/fileexchange/72085-matpower.
examples/4.switch_fidelity contains a power electronic switch model fidelity example that describes 5 different model fidelities for a half-bridge topology. Open model_fidelity_considerations_for_switching_devices.mlx for more information.
Supported MATLAB Version: R2025b and newer releases
