Behaviour of Constant Speed Wind Power System Under Different Operating Conditions

The use of renewable energy technologies has risen highly in the recent past due to the modern policies of reducing the carbon emission. Wind power is also one of such a system which has highest share after solar power. Thus, this paper concentrates on the behaviour of a fixed speed wind power system running under different operating conditions. Although the wind turbine system operating on variable speed with maximum power extraction feature is quite popular but such a generator has complexity in its control and not robust. While the fixed speed wind generators are robust and quite simple in structure and thus needs attention of the operator and researchers for its investigation. The mathematical modelling of the constant-speed wind turbine system connected to the grid has been presented in this paper and further has been examined under the variable wind conditions and disturbances in the grid in terms of voltage sag and voltage swell. The results found are useful for the academicians, new researchers as well as operators to know the behaviour of such a system under different disturbance scenarios and take the appropriate decisions.
