“…However in recent papers very promised results have been presented which show that the BDFIG is a viable solution for replacing the usual doublyfed induction generator [7]. The results of detailed performance comparison between a classic wound rotor double-fed induction generator and a brushless double-fed induction generator 75kW prototype provided in [7] show that at rated speed, the efficiency of the brushless generator at full power is only about 1% lower than the generator fitted with brushes. From other hand it has been shown that the real costs of the maintenance of the DFIG are bigger than costs caused by lower efficiency of BDFIG.…”

“…As distinct from DFIG the BDFIG rotor is unattainable for manipulation however two stators terminals are accessible. Nowadays the BDFM tends to be the natural alternative for the slip ring induction machines [5][6][7]. Although the absence of brushes makes the BDFM preferable for offshore wind turbines where maintenance is difficult, it still has not been widely applied for industrial power generation applications.…”

In the near future brushless induction machines could become the real alternative for the brush-geared doubly fed induction generators in windmills applications. Cascaded doubly fed induction generator (CDFIG) examined in the paper consists of two identical wound rotor induction machines having their rotors mechanically and eletrically coupled. In CDFIG both stators of connected machines are accessible. While stator of the first machine is directly connected to the grid, the stator currents and voltages of the second machine can be manipulated for power generation requirements. The paper presents an equivalent circuit of CDFIG at steady state as well the mathematical model of the twin stator cascaded machine. The PSIM simulation software is used for a preliminary investigations of CDFIG.

The turbine nacelle with traditional wind power generation system is heavy, especially in offshore applications due to the large mass of the power frequency step-up transformer operated at 50 or 60 Hz, and copper conductor generator. For example, the weight and volume of a 0.69/33 kV 2.6 MVA transformer are typically in the range of 6-8 t and 5-9 m 3 , respectively. The weight for a 10 MW direct drive permanent magnet generator is about 300 t. These penalties significantly increase the tower construction, and turbine installation and maintenance costs. The tower cost represents 26% of the total component cost of the turbine and on average about 20% of the capital costs are associated with installation. Typical maintenance cost of an offshore wind turbine is about 2.3 cents/kWh, which is 20% higher than that of an onshore based turbine. As alternative approaches to achieve a compact and lightweight offshore wind turbine nacelle, different concepts have been proposed in recent years, such as step-up-transformer-less system, medium-frequency (in the range of a few kHz to MHz) power transformer-based system, multilevel and modular matrix converter-based system and superconducting generator-based system. This paper aims to review the challenges, current research and development trends, possible future directions of the research to reduce the weight and volume of the nacelle. In addition, a comprehensive review of traditional wind power generation technologies is conducted in this article as well. Keywords:Offshore wind farm, power generation, research and development, compact and lightweight nacelle 2

“…in [9] investigated using the FE method the effects of parallel connections in the stator winding on vibration mitigation in the presence of rotor eccentricity. An analytical and experimental analysis of the generators vibration performance was performed in [10] showing that the vibration amplitude can be decreased if special attention is given to the choice of the BDFM power and control windings pole numbers, the number of loops in the rotor cage and the design of the laminated stator core.…”

In this work, a large-scale Brushless Doubly Fed Machine (BDFM) built in frame size D400 is tested at different operating conditions in order to examine its noise and vibration levels. A series of measurements were conducted on the machine to establish the main modes of excitation of vibration and noise developed by the machine. The harmonic spectrums of the vibration amplitudes are presented at two different rotor speeds at which the vibration level is highest, in order to determine the vibration components frequencies existed in the vibration spectrum. A harmonic analysis of the BDFM is then proposed in order to assess the sources of vibration in the machine.
