Real-Time Wind Turbine Simulators (Digital Twins)
ACMSL offers three professional real-time simulators — one per controllable wind turbine family. Each is a complete Digital Twin: the electrical, mechanical, hydraulic and control subsystems are fully modelled and run at real-time speed. Used by technical colleges, utilities and manufacturers in 8 countries since 2002.
3-1 Dual Speed Active Stall WT Simulator (DSAS)
Simulates the family of wind turbines with variable-pitch blades controlled into stall (Active Stall) and two operative hub rotational speeds. Generator is a squirrel cage induction machine directly connected to the grid (no power electronics). This is the recommended entry-level simulator — it introduces all the fundamental concepts without the added complexity of power electronics.
- Full simulation of the drive train, generator, yaw system and blade pitch actuator
- Two-speed contactor switching logic and soft-starter
- Aerodynamic braking (Active Stall) at cut-out
- Incidence log and alarm management
3-1-1 Introductory Video
3-1-2 Start and Stop Operations Video
3-1-3 Tutorial
Comprehensive tutorial (available in the Tutorial Viewer) covering the physical principles of Active Stall control, drive train mechanics, and all operational scenarios.
3-1-4 Practical Exercises
A set of guided practical exercises designed to develop operational competence with the DSAS simulator.

3-2 Rotor Resistance Controlled WT Simulator (RRC)
Simulates wind turbines that implement variable winding rotor resistance (also known as OptiSlip) on a wound-rotor induction generator. This topology provides limited variable-speed capability and is a key conceptual stepping stone toward understanding DFIG wind turbines.
- Full simulation of wound-rotor induction generator with external resistance control
- Pitch system and partial-load / full-load operating regions
- Power vs wind speed characteristic and slip regulation
3-2-1 Tutorial
Comprehensive tutorial covering rotor resistance control theory and operational scenarios.
3-2-2 Practical Exercises
Guided practical exercises for the RRC simulator.

3-3 Doubly-Fed Induction Generator WT Simulator (DFIG)
Simulates the most widely installed wind turbine family worldwide. The DFIG wind turbine uses a partial-scale Back-to-Back power electronics converter connected to the rotor winding of a wound-rotor induction generator. This enables wide-range variable-speed operation while only processing ~30 % of the rated power through the converter. Available in 50 Hz and 60 Hz grid versions.
- Full simulation of the Back-to-Back converter (grid-side and rotor-side)
- Real-time display of all electrical variables: voltages, currents, torques, power flows
- Wind gust scenarios, pitch system faults, converter fault scenarios
- 50 Hz and 60 Hz grid versions included
3-3-1 Tutorial
In-depth tutorial covering DFIG theory, power electronics, grid interaction, and operational scenarios.
