Constant Speed Variable Pitch Wind Turbine
Project Specifications
Project Title: Variable Pitch Constant Rotational Speed Wind Turbine
Project Aims
This project can be divided into 3 three parts. The first part is to develop a variable pitch propeller.
Then second and the main aim of this project is to design a control mechanism by which the propellers would rotate at a constant speed, at varying wind speeds by adjusting their pitch. This would be achieved by using wind sensors (anemometer) and a microcontroller. The sensors would measure the wind speed and feed that to microcontroller which would in turn calculate the pitch of the propellers to keep them rotating at constant speed. (Optional) After these parts of the project have been realised, we would enhance our project by aiming to generate electricity using this wind turbine. This would be achieved by using a trickle charge battery and an inverter to receive an A.C signal. Motivation
The motivation behind this project is to generate pollution free cheap electricity. Wind is a viable option to complement other types of pollution free generation. During this project we would be able to research the much debated issue -which yields higher generation, variable speed or the constant speed wind turbine.
Background
The wind turbine Technology started in 1980’s with a few tens of kW production power. Wind power production in the beginning did not have any impact on the power system control but as the power range of the turbines increased, control parameters became more important and it got necessary to introduce power electronics. In this project we would introduce constant rotational speed of the wind turbine by varying the pitch of the blades. At higher wind speed the blades will be turned out to have minimum contact with the wind and at lower wind speed the blades will be turned in to have maximum contact with the wind, in order to maintain at constant rotational speed.
