In this project, we were tasked to design a 10KW vertical axis wind turbine (VAWT) with the modification for better performance. We were able to analyse several alternative to the vertical axis wind turbine. The stress simulation, displacement simulation and factor of safety for our selected design are also highlighted in the report. Besides, there were not many publications on the modification on vertical wind turbine, hence we had to design and analyse most of the VAWT design based on our own understanding and guidance from supervisors. The report will also show the procedure done to fabricate the prototype and any further improvements which could be made to our design. The costs of fabrication and feasibility of the modified vertical axis wind turbine will also be included in the report.

This paper deals with a complete 1.5 MW Horizontal Axis Wind Turbine (HAWT) design using a novel Maximum Power Point Tracking (MPPT) algorithm based on real time machine testing and a low cost network communication system. It also includes a blade design study and simulation for a maximum efficiency and a high control strategy for maximum energy production with a minimum harmonic distortion for the generated current. The parameters studied are varied: electrical characteristics, static and aerodynamic, blade geometric profiles, and the influence of wind speed. The wind turbine uses a doubly fed induction generator « DFIG » controlled by a Pulse Width Modulation (PWM) strategy for 27 levels Cascaded three H-Bridge voltage source inverter. It will allow us to control the rotor voltage in magnitude and phase angle more easily & with high efficiency. This wind turbine was used on a 15MW wind farm. The study was conducted through several simulation software (Matlab, Catia, and Solid works). The whole control strategy, design principle and simulation results are shown & discussed.
