Simulation of a three phase motor and generator

Hi

I'm trying to create a Simulink model which simulates a three phase asynchronous motor, connected through a shaft to a synchronous generator.

My end goal is to send data (like rpm/field current) from this simulation to an WiFi-enabled Arduino board, which eventually sends this data to an IOT-platform (not Thingspeak).

I'm pretty new to Simulink so any help would be much, much appreciated!

Kind regards,

Dieter

Maybe you can use Simscape to simulate both coupled motors (https://www.mathworks.com/products/simscape-electrical.html). Inside simscape, SimPowerSystems can be used to model both synchronous and asynchronous motors/generators.

I suggest that you start looking some electrical models related to motors and generators:

https://www.mathworks.com/help/physmod/sps/examples.html?category=motors-and-generators

You can find an example where a synchronous generator is mechanically coupled. Maybe you could take it as a reference and include the asynchronous motor.

Hope it is helpful

Yeah, I came across those examples, thanks!

I got the coupling of the asynchronous motor and synchronous generator more or less figured out.

The challenge now is to send the right data via serial to the Arduino.

Hello Dieter,

for communicating with the arduino, you have this support package: https://www.mathworks.com/matlabcentral/fileexchange/47522-matlab-support-package-for-arduino-hardware

additionally, if you have the coder products, you could actually generate code an run simulations on the arduino if that would be easier than having an active instance of matlab talking to the arduino.

If you go the code generation route, you would want to think about switching from using simpowersystems (now called specialized power systems) to using the simscape electrical core components (they are blue instead of black). The Simscape components support a wider range of code generation options than specialized power systems.
