Incorporation of finite element analysis into annual energy loss estimation for permanent magnet wind turbine generators

Several methods of estimating the annual energy losses for wind turbine generators are investigated in this paper. Utilizing a high amount of transient simulations with motion is first demonstrated. Usage of a space-time transformation for prediction of iron losses is also explored. The methods, which use varying amounts of simulation results and computational resources, are compared based on time required and consistency in varying wind climates.
