Impact of the design method of permanent magnets synchronous generators for small direct drive wind turbines for battery operation

Abstract

In stand-alone direct drive wind turbine power generators, working on battery, the permanent magnets synchronous generators is the most common solution. The system can be analyzed as the combination of three subsystems: wind turbine, electric generator and the load, which is the battery for energy storage. For high energy transfer from wind to the battery, those components should be designed in a particular way. The paper approaches the impact of the component parameters of each subsystem on power transfer from wind to the load
