N2 - A proper maximum power tracking algorithm for a Wind Energy Conversion Systems (WECS) requires all the relevant losses to be modelled, especially copper and core losses. Such accurate loss modelling is not a simple task when the machine operates connected to a power converter. In this paper we validated an equivalent circuit for a novel air-cored PM generator by comparing the results from a transient-nonlinear Finite Element Model (FEM) of the generator and by experimental testing on a 20-kW prototype. Finally we present the benefits of a proper integrated optimisation in terms of annual energy yield and average losses. We suggest that a detailed loss modelling is desirable at a design stage for an optimum matching between machine and rotor blades.
