Energy Efficiency of the Wind Power Generator

The main share in the annual electricity generation wind farms provides during periods when the wind speed exceeds 8 m/s. Therefore, when designing a synchronous generator of wind power plants, it is necessary to provide maximum efficiency for rotor speeds corresponding to such values of wind speed. In generators of wind turbines or micro hydroelectric power stations, it is advisable not to observe the known ratio of the equality of constant and variable losses. The ratio ensures the maximum efficiency in the nominal regime. To increase the energy efficiency of the installation, the generator should be specifically designed. Thus, the maximum efficiency point of the generator is shifted to the zone of maximum loads and rotation frequencies - to the right of the nominal point.
