LABORATORY EMULATION OF WIND TURBINE OPERATION
Project Area of Specialization BlockchainProject SummaryThe increasing demand for electricity in addition to the need to minimize environmental problems such as global warming had led to the development of renewable sources for production of electricity in recent years.Thus, a worldwide growing number of large and small wind farms installed can be verified.
The analysis of the efficiency of a wind turbine (WT), based on an adequate simulation of its behavior, is an important step in the research and development of technologies for wind generation. One possible and helpful tool uses a dedicated hardware and software that intends to emulate a real WT in a reduced scale. This tool is a so-called WT emulator.
The project is a system based on the development of a DC motor based Wind Turbine Emulator (WTE) and its performance verification through simulation. Wind turbine emulator mimics the behaviour of wind turbine for hardware level simulations. This system has a DC motor coupled with the Induction generator, speed of which is controlled as per the speed reference calculated by solving the mathematical model of wind turbine. An induction generator is coupled to the DC motor and bidirectional inverter is connected to the terminals of the generator. We can execute the mathematical models of the newly developed or modified wind turbine and can simulate the speed/power of profile of turbine on hardware environment directly for different wind speeds & pitch angle.
The software part implemented in ARDUINO receives load torque signals and the pre-set wind speed as inputs and generates a reference current as an output signal. The reference current is connected to the set point of a Proportional Integral(PI) current controller that drives the thyristor Bridge for armature control of the DC motor.
Project ObjectivesThe following objectives are attained of this project:
- Wind turbine emulators (WTEs) are designed to simulate the steady-state and dynamic behavior of the system.
- Study of wind turbines, their types and method of their working.
- Modeling of wind turbine and its analysis.
- Power speed and torque speed characteristics obtained from the modeled wind turbine.
- Modelling of separately excited DC motor and obtaining its characteristics.
- Realisation of model for speed control of DC motor.
- Comparing and controlling the DC motor model to obtain the wind turbine characteristics so that the DC motor can emulate the wind turbine applications.
By using emulation system, we aim to reproduce the dynamic behavior of the wind turbine torque on the generator shaft: it provides the testing facilities to optimize generator control strategies in a controlled environment, without reliance on natural resources.
Project Implementation Method•The Wind Turbine Emulation using DC motor is based on controlling the motor power without adjusting the speed.
•The inputs of the WT mathematical mode are: Wind velocity, Turbine angular, Speed and Pitch Angle. The Torque is output.
•The reference current is calculated from the reference torque output and is compared with armature current and the error is processed by PI Controller.
The PI controller output is passed to a DC drive to regulate armature voltages.
Benefits of the Project- This operational wind turbine emulator could be used for research on a small wind energy conversion system and thus form a test-bed to experiment and develop other control strategies.
- WTE also plays a vital role in designing control strategies as well as for validating the control algorithms. It is also used for developing power electronic circuits of the wind energy conversion system.
- It is also employed for testing the generator’s control techniques. Above all, it is vital for analyzing the performance of WEC.
The concept of wind turbine was studied in detail and the modelling was done. The project develops a wind turbine emulator that provides characteristics of wind turbine based on wind speed and other gradient factors. It verifies the modeling of wind turbine as a speed source that can be further used for development of more efficient energy converters for extraction of power from wind turbine. Such emulators are vital for development of WECS to encounter all sorts of unpredictability in wind and environment in order to ensure the continuity of wind energy hence contributing to more encouragement of Wind Energy. The project implements speed control of DC motor using PI controller. DC choppers are used. The characteristics of wind turbine with DC motor are obtained by using PI controller
