本文的目标是完成一项关于容错机在风力发电机纵摇控制中的有效性的研究。俯仰控制既有助于抓住风的最佳迎角的叶片的翼型，并把叶片出风当最大速度超过。为了完成这一任务，使用电机来控制叶片的俯仰角与风速的函数。电机中可能出现的故障会使螺距控制系统停止工作，从而大大降低风力发电机的效率。螺距控制机的容错能力可以避免这些问题。本文研究了一种容错开关磁阻电机。由于它简单、便宜，是这些重要应用的最佳选择。采用数值场计算方法分析了机床的性能。为了研究机床的驱动系统和容错能力，将两个仿真程序耦合在一起进行了高级联合仿真。
The paper's goal is to accomplish a study regarding the usefulness of a fault tolerant machine in wind turbine pitch control. The pitch control both helps to catch the wind at the optimal angle of attack of the blade's airfoil and to turn the blades out of the wind when maximum speed is exceeded. To fulfill this assignment electrical machines are used to control the blade's pitch angle function of wind's speed. The faults that can occur in electrical machines can stop the pitch control system, decreasing drastically the efficiency of the wind turbine. Fault tolerance ability of the pitch controlling machines can avoid such issues. In the paper a fault tolerant switched reluctance machine is studied. As it being simple and cheap it is optimal for such vital applications. Numerical field computations were used to analyze the machine's behavior. An advanced cosimulation was performed by coupling two simulation programs in order to study the machine's drive system and fault tolerance capacity.
