Three-Phase Custom Synchronous Machine

This example shows a custom Simscape™ implementation of a Synchronous Machine (SM). To view the SM source code, double-click on the Synchronous Machine block and then click on the hyperlink 'Source code'.

This test circuit shows the SM being used as a generator, the field has constant voltage applied, and the rotor is turned at a constant speed. The overall model has been initialized to start in periodic steady state to supply the 500MW load.

Results from Real-Time Simulation

This example has been tested on these platforms:

• Speedgoat™ Performance real-time target machine with an Intel® 3.5 GHz i7 multi-core CPU and 4 GB RAM.

• dSPACE® SCALEXIO LabBox with Intel® Core XEON E3-1275v3 at 3.5GHz and 4 GB RAM.

You can run this model in real time with a step size of 50 microseconds by using the Simscape local solver. For small sample rates, a task overrun might occur during the initial task execution due to a cold cache. To avoid this overrun, if the selected platform supports these options, relax the start-up behavior by specifying a limited number of task overruns or increasing the sample time of periodic tasks during the start-up phase of the real-time application.
