Hi,
I want built a system on simulink where I've an a assynchronous motor with squirrel cage rotor driving an a assynchronous generator to test if my the control system of the generator is working. So my system is something like the image bellow. My problem is that I dont know if the block corresponding to the motor is really working like a motor and not like a generator. And the same doubt applies to the generator block.
I read on simulink help that when Tm is <0 the block works like a generator and when it's positive works like a motor so I've used two fcn blocks to give different signals to the two machines. Can this be done this way? How can I confirm how the two machines blocks are operating? The conection to grid of the two machines (Vn=220V, fn=60Hz) makes sense?

You can look in the "m" measurements bus of each to see if you are getting the voltages, powers, etc that you expect. Just use your bus selector to get the signals and then hook up scopes to see how the power is flowing. There is also a measurements block you can put on your bus to get the values there.
Or perhaps you would like to start with an example? Emergency Diesel-Generator and Asynchronous Motor
