“…[62,63]. By using direct mathematical transformation, a two-axis model of cage-rotor BDFM was proposed in [64] and the simulation results were also published in [65]. The design of the BDFM is complicated due to the complexities of determining the overall electric loading and magnetic loading and dividing them between the two stator windings.…”

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

“…But, the complex calculation is detrimental to the direct control. When the rotor speed is a constant, the BDFM rotor d-q model can be described by a 6-order matrix that can be well used in the simulation of BDFM dynamic and steady state characteristics and simple close-loop control in [3][4][5]. If the rotor saturation is neglected and the model of power winding and control winding are built on their own synchronous reference frame, the input or output will no longer be a time variable, but a constant.…”

Using rotor d-q model as a start point, this paper analyses the mathematical model for BDFM based on synchronous reference frame. And, based on characteristics of BDFM, a new type of power control system is designed by using the gap flux oriented vector transformation control technology. In order to no existing of the big power storage capacitors, the matrix converter is used to control windings of the generator to carry out the AC excitation in the paper. Thus high efficiency energy generation is achieved through maximal wind energy capturing. Simulation results verify the correctness and effectiveness of this control strategy.

“…Wind energy capturing and conversion efficiency can be improved by taking advantage of variable-speed constant-frequency (VSCF) method which is a very suitable operation method for wind power generation. In variable-speed constant-frequency constant-voltage wind power generation field, the Doubly-Fed Induction Generator (DFIG), in which wound rotor is used to synchronize induction generator, is followed with wide interest in [1,2]. But DFIG has brush and slip ring which limit its application in harsh environment.…”

Using rotor d-q model as a start point, this paper analyses the mathematical model for BDFM based on synchronous reference frame. And, based on characteristics of BDFM, a new type of power control system is designed by using the gap flux oriented vector transformation control technology. Meanwhile, because the generator structure is complex and the generator parameters are variable, fuzzy control is used for the power loop of the outer loop to further enhance the robustness of the system. Thus high efficiency energy generation is achieved through maximal wind energy capturing. Simulation results verify the correctness and effectiveness of this control strategy.
