- Average Model: This model simplifies the electrical behaviour by averaging the power over one cycle. It focuses on slower dynamics, like how the control system responds and how power flows, without getting into the details of switching events. This makes it faster to simulate, ideal for control design or stability analysis over longer periods (a few seconds). It allows for larger time steps (about 50 microseconds).
- Phasor Model: This model uses phasors (complex numbers) to represent the system in a steady-state condition, focusing on the overall voltage and current changes over time. It's best for studying how the system behaves during disturbances or faults over longer periods (from seconds to minutes). It simplifies the simulation, making it faster to analyse long-term dynamic behaviour.
- Detailed Model: This model includes all the details, capturing the full dynamic behaviour of the system, including fast transients and harmonics. It provides high accuracy, making it useful for detailed studies like protection and power quality analysis. However, it requires more computational power and time, as it uses a very small-time step (around 5 microseconds).

Hi Pritam,
In Simulink, the "Average Model," "Phasor Model," and "Detailed Model" are different ways to simulate electrical systems like wind farms using "Doubly-Fed Induction Generators" (DFIGs). Each model provides a different level of detail and simulation speed, depending on your needs:
For more information on “Simulation Methods of the DFIG”, refer to the following MathWorks documentation link:
Hope this helps.
