horizontal- axis wind turbine with a 20-m diameter rotor is 30% efficient in10m/s winds at 1atm of pressure and15◦C temperature. a.How much power would it produce in those winds? b.Estimate the air density on a 2500-m mountaintop at10◦C? c.Estimate the power the turbine would produce on that mountain with the same wind speed assuming its efficiency is not affected by air density
Synchronous Generator
In comparison to an asynchronous generator, it is a machine where the rotor speed is equal to the rotating magnetic field produced by the stator, i.e., mechanical speed is equal to the electrical speed, thus called synchronous, and not asynchronous.
Salient Pole Rotor
Salient pole rotor includes a large number of exposed poles mounted on a magnetic wheel. The construction of a bright pole is as shown in the image on the left. The proposed poles are made of metal laminations. The rotor winding is provided on these poles and is supported by pole shoes.
