| Summary: | The growth rate of wind energy installed has initiated a need for estimation and accurate analysis of transient stability of the power systems because of its intermittent natural. This paper investigates the voltage enhancement and the transient behaviours stability evaluation of a grid connected wind turbine with squirrel cage induction generator. The methodology chronologically provides an overview about the power grid, wind turbine modelling, and the reliability and stability responses of the distribution network. Firstly, in order to estimate the point of connection for wind turbine, a practical power distribution network is being modelled and compared using load flow method. The steady state analysis is performed to determine the voltage magnitude profile: particularity weak bus voltage. Secondly, by using an optimal power coefficient and the correlation of a power law exponent, a wind turbine induction generator model is proposed considering function of velocity and elevation. Finally, dynamic and transient behaviours are investigated for reliability and stability of power systems using voltage bus and wind rotor speed analyses. The simulation results show that wind turbine integration enhances the weak bus voltage and supports dynamic and transient stability analysis. © JES 2014. |
