Wind Turbine Emulator 

The Wind Turbine Emulator is a real-time, hardware-in-the-loop (HIL) platform that replicates the mechanical and electrical behavior of a wind turbine under controlled laboratory conditions. It eliminates dependence on natural wind while allowing students and researchers to study turbine dynamics, power conversion, MPPT algorithms, and grid interaction with high repeatability and safety.With advanced control architecture and support for external algorithm integration (MATLAB, Simulink, FPGA, etc.), the system facilitates real-time experimentation, deep system modeling, and algorithm validation, all within the safety of a laboratory. 

Key Features

  • Three Operating Modes: 1. Manual Mode: Users manually control the Wind speed to study Wind Turbine Emulation. 2.Simulated Mode: The emulator calculates real-time turbine behaviour using predefined wind profiles.3. Table Mode: Feed manual wind profile for Wind Turbine Emulation Study.
  • User-Defined Turbine Modelling Capability: Users can input custom wind turbine mathematical models (torque-speed or power-speed equations) into the system to emulate specific turbine types, enabling flexible, research-driven experimentation.
  • Real-Time Wind Turbine Emulation: Accurately replicates mechanical characteristics like torque-speed and power-speed curves under varying wind speeds, rotor diameters, and pitch angles.
  • Hardware-in-the-Loop Architecture: A DC motor, driven via control algorithms, acts as the prime mover to simulate turbine behaviour physically—removing reliance on actual wind.
  • MPPT Algorithm Development & Testing: Supports integration of advanced MPPT algorithms like P&O, Incremental Conductance, and TSR-based methods, using live system feedback.
  • Cp–λ Curve Plotting & Performance Visualization: Generates real-time Power Coefficient (Cp) vs Tip Speed Ratio (λ) plots to evaluate turbine efficiency across varying wind profiles.
  • Open Access to converters: Includes a bidirectional converter, buck converter after generator, buck converter for DC Motor Control, and three phase inverter for power control.
  • Open Control Platform: Compatible with MATLAB/Simulink, DSP, or FPGA for implementing and testing custom control strategies, MPPT logic, or smart grid algorithms.
  • Advanced Monitoring & Data Logging: Monitors and logs parameters like wind speed, rotor RPM, torque, voltage, current, and power. Supports CSV export and graphical analysis via PC-based software.
  • Standalone and Grid Connected modes: Able to work in both standalone and grid connected modes.

Technical Description

  • The Wind Turbine Emulator is built on a real-time hardware-in-the-loop (HIL) architecture that reproduces actual wind turbine dynamics inside a laboratory environment.
  • A mathematical turbine model continuously computes aerodynamic torque and power based on wind speed, rotor radius, tip speed ratio, and pitch angle.
  • The calculated torque reference is applied to a controlled DC motor, which physically emulates the mechanical behaviour of a turbine rotor.
  • This motor drives an electrical generator, producing output characteristics identical to those of a real wind turbine under steady and variable wind conditions.
  • Generated electrical power passes through open-access converters and inverters, allowing detailed analysis of power conditioning, DC link control, and energy flow.
  • Real-time controllers execute MPPT and grid-interaction algorithms using live sensor feedback from voltage, current, speed, and torque sensors.
  • All operating parameters are continuously monitored, logged, and visualised through PC-based software, enabling repeatable testing, performance validation, and advanced research studies.
