“…The WT gearbox has the function of increasing the shaft angular speed that is connected with a generator of electrical energy. Block scheme [20] of the conversion of mechanical energy to electrical energy in wind turbines is given in Figure 4. Most commonly used is a three-stage WT gearbox [21].…”

The trend of wind turbine development has a special significance in the exploitation of renewable energy sources. At higher altitudes, we have better wind energy utilization higher speed and their conversion are achieved in the best possible use of wind turbines. The development of new technologies opens space for a new generation of wind turbines with a 20MW rated power. In recent years, various feasibility studies have shown that wind turbines with large rotor diameter and high towers give positive shifts in the analysis of structural and aerodynamic parameters, with a focus on reducing overall mass and damping vibrations due to the use of new materials. In this paper, the evolution of high power wind turbines and an overview of the technological development of the basic components of the turbine will be presented. Perspectives in the further development of wind turbines with rated power above 20MW will be also considered.

“…Based on these specifications, the modified Taguchi method is used to find the optimal design of the generator. The method is useful in finding optimal parameters and reduces the time needed for simulations [9]. In this paper, the targets of the generator design are a smaller and lighter generator, lower inductance, and a shorter total length of HTS wire.…”

A Flux Pump (FP) exciter injects DC current into the High Temperature Superconducting (HTS) field coils of an HTS rotating machine without a slip ring and current leads. When designing a large-scale HTS generator with integrated FP exciter, the coil inductance, field current, and time constant need to be optimized for better performance of the machine.In this paper, a 12 MW HTS wind power generator with integrated FP exciter was designed. The essential parameters of a 12 MW HTS generator were optimised using the Taguchi method targeting the minimization of weight and volume of the generator, the length of HTS wire, and the inductance. Especially, the FP exciter was adopted for supplying DC current to the HTS field coils without the power supply and the slip ring. The magnetic field distribution was analysed using the 3D finite elements method. The induced DC current and charging and discharging times of the FP exciter were compared with the metal current leads for confirmation of the effectiveness of the FP exciter. The detailed results of the HTS generator design were discussed in detail.

“…However, the gearbox seriously decreases the reliability of the system, and increases the difficulty of repair and maintenance with the increase in capacity. In contrast, the direct-driven synchronous generation system, the electrical output of which is controlled by an inverter, is more promising for future application [6][7][8]. However, there are two serious problems that must be overcome for the application of direct-driven wind turbine generators, namely (a) the huge generator weight, and (b) the low generator efficiency due to the increase of the generator capacity and an ultra-low operation speed of about 10 min −1 .…”

The research and development of large-scale wind turbine generators have become a future trend in green renewable energy field from the dual perspectives of the environment and economics. In this work, an electrical design method is first proposed and applied to different types of wind turbine generators, including the high-temperature superconducting (HTS), the permanent magnet (PM), and the traditional copper generators. The optimal electrical designs of the three types of 10-MW wind turbine generators are then created based on the developed design program. Second, the influences of the rated revolution on the basic performance parameters of the HTS generator are investigated, and the results are compared with those of the other two types of generators. It is found that the generator weight decreases with the increases of the rated revolution and the stator outer diameter, and the optimal rated revolution for a generator with a large stator outer diameter is determined to be 40 min-1. Moreover, the weight of the field parts is found to have the same regulation rule as the generator weight. Finally, the design results of the three types of wind turbine generators are comparatively discussed, and it is found that the HTS wind turbine generator is superior to its two counterparts.
