“…The rotor configuration is a nested-loop design with six nest and five loops per nest. It was proved in [19] that the BDFM has 180 o symmetry in its magnetic flux pattern and therefore only half of the machine cross-section is simulated, which reduces the computational time significantly.…”

In this paper, a new optimized rotor design for Brushless Doubly Fed Machines (BDFMs) is proposed. The BDFM is considered as an attractive generator particularly for offshore wind power generation and also as a replacement for doubly fed slip ring induction generators. This is due to its higher reliability and lower maintenance reported in the literature. It is shown in this paper from the study of the magnetic field distribution in the rotor core that the conventional design of the BDFM rotor iron core can be modified, leading to a lighter machine. The proposed design method is supported by an analytical study and its practicality is validated using 2-D Finite Element (FE) analysis. A 250 kW experimental BDFM with frame size D400 is considered as the prototype machine. Index Terms-Brushless doubly fed machine (BDFM), rotor back iron, finite element analysis (FEA), magnetic circuit, iron saturation, magnetic flux density.

“…Up to now, the presented models for the BDFIG include: (i) finite element (FE) model [10,11], (ii) coupled circuit model [12], (iii) d − q and reduced d − q models [13] and (iv) EEC model [13]. Furthermore, a simplified version of the EEC is used in design of the BDFIG which is insufficiently accurate [7].…”

The brushless doubly-fed induction generator (BDFIG) has substantial benefits, which make it an attractive alternative as a wind turbine generator. The aim of this work is to present a nodal-based magnetic equivalent circuit (MEC) model of the BDFIG which provides performance characteristics and flux density distributions. The model takes into account stator winding distributions, special configuration of rotor bars, slotting effects, teeth saturation, flux fringing and current displacement effects. The real flux tubes are considered for creating an MEC network and calculating its non-linear elements. A method for simplifying the rotor magnetic network has been applied and Gauss elimination with partial pivoting approach is used to solve the equation system with sparse coefficient matrix. The model parameters are based solely on geometrical data and thus it is an appropriate tool for population-based design studies instead of computationally intense analysis of the finite element method. The steady-state results of the proposed model are verified experimentally. The comparisons demonstrate the effectiveness of the proposed model especially when the core is magnetically saturated.

“…The resulting flux pattern in this machine has 180 o symmetry. Therefore, only half of the machine domain is analysed as in [3]. The mesh used for the finite element analysis is shown in Figure 4 and has 23231 elements.…”

Time-stepping finite element analysis of the BDFM for a specific load condition is shown to be a challenging problem because the excitation required cannot be predetermined and the BDFM is not open loops stable for all operating conditions. A simulation approach using feedback control to set the torque and stabilise the BDFM is presented together with implementation details. The performance of the simulation approach is demonstrated with an example and computed results are compared with measurements.
