“…As an example, a gearless FSG was optimized on the basis of the proposed method of constructing the substituting loading profiles for a wind turbine. The wind turbine's initial profile was specified by nine maximum-power operating points described in [11] over a range of wind speeds. The wind speed was assumed to be distributed according to the Rayleigh distribution.…”

Due to the increasing need for direct-drive wind turbines, a large number of papers are dedicated to the optimization of low-speed wind generators. A permanent-magnet flux-switching machine can be a valuable option to use in such applications. This paper describes the optimization procedure of a direct-drive flux-switching wind generator. The average losses, the required converter power, and the cost of permanents magnets were chosen as the optimization objectives. To reduce the calculation efforts during the optimization, a method to construct the substituting load profiles is proposed. Two-mode and three-mode substituting profiles were constructed on the basis of the nine-mode initial profile. The losses calculated under the two-mode, three-mode, and nine-mode profiles accurately coincided, which supported the use of the low-mode substituting profiles instead of the initial one. During the optimization, the average losses decreased by 30%, which corresponded to an increase in the average efficiency by almost 6%. The required converter power was decreased by 10%. The total active material mass, cogging torque, and torque ripple were also slightly decreased.

“…This paper describes the optimal designing of the FSG for the wind turbine operating at the wind speed range from 4 to 12 MPS (meter per second) [8]. The turbine rotational speeds, its powers and torques at nine maximum operating points corresponding to the wind speeds from this range are given in Table 1.…”

“…The following criteria are used for its optimization: the average power losses in the generator, the cost of permanents magnets and the required AC-DC converter (active rectifier) power. An example considered in that work includes the initial wind turbine load profile consisting of 9 operational modes [8]. The two-point and three-point substituting profiles are used to replace the initial profile.…”

Optimal Design of Gearless Flux-Switching Generator with Ferrite Permanent Magnets

In this paper, the optimal design of the Flux-Switching Generator with ferrite magnets based on a two-mode substituting load profile for a gearless wind generator is considered. A one-criterion Nelder-Mead method is used to optimize the generator design. The optimization function is constructed mainly so as to minimize the average losses in the generator and the required AC–DC converter power. Also, the Flux-Switching Generator torque-ripple and the ferrite magnets volume are minimized. Using substituting profiles instead of initial ones reduces the calculation efforts substantially. The paper contains the analysis of the optimal design of the Flux-Switching Generator with ferrite magnets.
