Keywords: wind turbine, energy conversion, permanent magnets, mathematical model

Abstract

The usage of the wind is actual branch in development of renewable energy. One of the main components in wind turbine is electric generator. Experience and development of foreign and domestic scientists showed that at present the most effective are generators in wind turbines, which are made excitation of permanent magnets from rare earth elements (SmCo, NdFeB). The way to increase the effectiveness of transformation the wind energy to electrical is possible with help of improvement the design of existing types of generators, using new technologies and materials or by design new technical solutions. This article deals with analysis of parameters and characteristics of traditional permanent magnet generator with cylindrical stator and axial flux permanent magnet generator with double sides active surface. The analysis is based on developed 3D field mathematical models. The usage of axial flux permanent magnet generator in case of modular usage allows to increase the power of wind turbine and to improve the usage of active materials of generator (electrotechnical steel, permanent magnets, copper). Axial flux permanent magnet machines has less volume and mass of active materials compare to traditional cylindrical machines the same power. This is especially true for the ratio of power and volume of machines in the range of power from 0.25 to 10 kW. The power of axial flux permanent magnet is in range from the parts of W to megawatts. By increasing the output power of the generator, the contact surface of the shaft and rotor connection decreases disproportionately to the total volume of the machine, which limits the output power of the machine in terms of the mechanical integrity and strength of the machine shaft.
