An experiment with tripping and re-connecting a MW wind turbine generator was carried out at the Nøjsomheds Odde wind farm in Denmark. The experimental results are used primarily to validate the shaft system representation of a dynamic wind turbine model. The dynamic wind turbine model is applied in investigations of power system stability with relation to incorporation of large amounts of wind power into the Danish power grid. The simulations and the measurements are found to agree. The experiment was part of a large R&D program started in Denmark to investigate the impact of the increasing capacity of wind power fed into the Danish power grid.


Disregarding wind turbines has been conveyed an unmistakable fuel source and does not corrupt the air like other power assets, which relies upon consuming of petroleum products, for instance, coal or vaporous oil, since wind is a fluctuating wellspring of vitality it has experienced high request music and isn't fit to meet the base burden vitality request. Along these situation, this circumstance forces wind turbine generator system to have a power molding circuit called control converter that should be bore of changing the generator repeat and voltage to grid anyway existing converters are doing combating with low solicitation sounds just so when high request music occurs, there is a debasement in power quality and wind turbine needs single multi arrange converter. As to issue, this work showed a multi request symphonious remover subject to mixed multilayer influence converter which avoids high music bending to upgrade the influence idea of wind based influence plant by considering the going with attributes that prompts sounds, for instance, control adversity to adjust up to this expansion type rectifier is used, inadequacy current that is changed by imperfection current limiter and the high repeat part that is controlled using nonlinear inductor, at long last commotion is decreased by cascaded c type filter so this structure can battle with the high consonant mutilation and kept up the impact quality and the transient security of the wind turbine.
