Hello everyone,
I recently tried to model a diesel generator in Matlab-Simulink. I implemented an engine governing system as well as an excitation system following the values from Matlab’s Emergency Diesel Generator model to a create a diesel generator using a Synchronous Machine with a power rating of 16kVA, 400V and 50hz (one of the preset models).
After running the simulation for 24s (each second is supposed to represent an hour) with a powergui block using the discrete solver (with a time step of 2e-5), I obtained these results and I’m not sure why there are periodic dips in the voltage (and current). Can anyone provide me with answers?

Thank you in advance !Hello everyone,
