Abstract In this paper a system of a grid side and a generator side converters, both working with a common capacitor, is presented. The 6-phase asymmetric inset-type SMPMSM generator is used. A large pole pair number of this generator enables a gearless wind turbine operation. The fundamental and 3rd harmonic cooperation is used to increase the generator performance. This is accomplished by means of the 3rd harmonic current injection. For that reason the generator side converter must have a neutral connection.

Aiming at the defects and potential safety hazard in design of wind turbine generator foundation, taking the wind power project in Huitengxile as an example and based on ANSYS platform, 3-D numerical model is established by introducing the nonlinear contact between the stub of tower structure and the foundation concrete, and the contact between the concrete foundation and subgrade, the effect of step height and load on the stress status of spreading foundation for large wind turbine are studied. The research results provide reference for optimization and design of wind turbine generator foundation.

Abstract A reliability analysis of wind turbine systems applies to chosen localizations in Poland was inspected. The average availability, capacity factor and energy efficiency of the large wind turbine generator have been analyzed. It is noticed that if a failure rate decreases by modernizing assemblies by removing chosen subassemblies and reconstructing others, an average lifetime of the wind turbine enlarge noticeably. Moreover, it is possible to find, both poor and excellent wind potential on areas classified as not preferable for a wind industry.
