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

“…The stator power and control windings are connected to the three phase power grid; the power winding is connected directly while the control winding is connected through a bi-directional static power converter. In this system the reactive power compensation can be realized through the power converter in the control winding or through this converter plus a capacitor bank in the grid [4]. A simplified block-diagram of the BDFIG complete system is presented on Fig.…”

“…An alternative to overcome this drawback is the brushless doubly-fed induction generator (BDFIG) [2][3][4]. BDFIG has its origins in the technology of cascade induction machines and consists of two three-phase windings with different number of pairs of poles in the stator and a special rotor cage.…”

The vector control of the Brushless Doubly Fed Induction Generator (BDFIG) was implemented in Matlab/Simulink/SymPowerSystems using a rotating reference frame fixed on the power winding flux. The control algorithms of the grid-side and control-side converters can regulate the active and reactive power independently. The measure of the power winding flux angle, realized using a Phase Locked Loop (PLL), showed good performance during the system startup and has demonstrated a robust behavior under noisy voltage and current signals. A synchronization strategy is proposed that acts on the control-side converter current control loops to ensure the conditions for a smooth connection. Soft and fast synchronization is achieved at the minimum rotating speed. The simulation results of the dynamic performance of Maximum Power Point Tracking (MPPT) under speed mode control are presented.

“…To date, a number of large BDFMs have been made, for example in Brazil with a 75 kW machine [3], China with the design of a 200 kW machine [4] and the 250 kW BDFM reported by the authors in [5] and shown in Figure 2 on test bed. The latter was built in a frame size D400 as a steppingstone towards a megawatt scale BDFM wind turbine.…”

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.
