Various Poles Numbers 800 kW Synchronous Wind Generators for Arctic Region

For the development of Russia Arctic region, wind power plants of domestic production are required. The article analyzes the parameters of 800 kW permanent magnets synchronous generators for the Arctic region. The generators provide for the magnetic flux concentration and the use of a concentrated stator winding. During the investigation, an original calculation program was used, generators variants with a different number of poles were analyzed when the air gap value changed. The influence of variable values on the generators parameters and characteristics is estimated. Numerical studies of a two-dimensional electromagnetic field by the finite element method for various operating modes are performed. Generators provide for the possibility of working with a single-stage gearbox in places with different estimated wind speeds and are considered in the work as a basic promising option for wind power in northern latitudes.
