Electric Generator

The mechanism of an electric generator works on the principle of electromagnetic induction. The principle explains that when a straight conductor moves in a magnetic field, then the current is induced in the conductor. According to the principle, the conductor coil is rotated rapidly between the poles of a magnet which is known as an armature.

Wind energy

Wind power generation took place in the United Kingdom and the United States in 1887 and 1888, but modern wind power is considered to have been first developed in Denmark, where horizontal-axis wind turbines were built in 1891 and a 22.8 metre wind turbine began operation in 1897. The modern wind power sector emerged in the 1980s.

Introduction to the Doubly-Fed Induction Generator for Wind Power

The power electronic converters need only be rated to handle a fraction of the total power – the rotor power – typically about 30% nominal generator power. Therefore, the losses in the power electronic converter can be reduced, compared to a system where the converter has to handle the entire power, and the system cost is lower due to the partially
