Impacts from wind farms

摘要

After recently completing two EESA (Electric Energy Society of Aus-tralia) wind power seminars in Sydney and Newcastle, I look with amazement at the aggregate magnitude of the MW capacity of wind farms in South Australia. Half of Australia's 2000MW of wind capacity is now installed in South Australia and further windfarms are be-ing planned. At our seminars, Graham White and Dr Matthew Bechly of Garrad Hasson gave expert descriptions of the state of the art of wind power technology. Machines from 1MW to 5MW are now common with 15M W machines predicted for the future. Double wound induction machines with power electronics are now routinely used with other controls to regulate power output, turbine speed and power factor.
