It provides safety against failures like over-speeding of wind turbines. It is advantageous because it provides suitable braking by frictionless brake. Most of the braking systems utilize friction forces to transform the kinetic energy of a moving body into heat that is dissipated by the braking pads. The over use of friction-type braking systems causes the temperature of the braking pads to rise, reducing the effectiveness of the system. There relative motion between the magnet and the metal (or alloy) conductor produces an eddy current that induces a reverse magnetic field and results in deceleration. This braking is provided by generation of eddy current phenomena. This eddy current is produce in the stationary plate which opposes the rotary motion of rotating plate and finally rotating plate is being stopped. The many of advantages it having non-contact, no wear, no electric actuation ,light in weight so it can be very useful for wind turbine. Without using friction, an eddy-current braking system transforms the kinetic energy of the moving body into heat energy that is dissipated through the eddy current in the conductor. This concept is used for the braking of wind turbine to avoid the failure of wind turbine.en-USProject Report - EEProject Report
