Improved design and control of brushless doubly-fed reluctance machine generators for wind power applications

The growing importance of the reduction in greenhouse gas emissions over the coming years is driving the increased usage of renewable energy sources such as wind power. Currently the cost of wind energy is considerably higher than fossil fuel energy sources. Part of the reason for this is the initial cost and ongoing maintenance of the wind turbines. The proposed research considers a new kind of generator based on the Brushless Doubly Fed Machine (BDFRM) that has the potential to lower the initial cost of the generator/inverter hardware of the wind turbine, and also decrease the ongoing maintenance costs. If the research is able to show that the BDFRM is able to realise its potential, then this will aid the further use of wind energy.
