The Gazelle is a wind turbine with a fixed blade angle and utilising a 22 kW induction generator to produce three phase electricity that is exported direct to the national grid. The advantages of this type of turbine assembly are generally considered to be the relatively low cost of construction and the small size because of the reduced amount of moving parts that are required. The existing system has disadvantages. The primary ones that will be considered here are the problems encountered adapting to a change in wind conditions. Energy is lost as the traditional method of operation requires this type of turbine to be shut down at low or high wind speeds. There are improvements that can be made. After consideration of many areas that can be optimised, the most beneficial to the amount of energy that can be produced are the selection of the correct blade angle for a specific. location and the additional power that can be generated resulting from the redesign of the control strategy. These are considered in the research program described. A picture of a Gazelle is shown as Figure 1-1.
