The current confluence of enhanced environmental awareness, positive economic conditions and technical developments has led vigorous global efforts toward making wind power a key component of renewable and sustainable energy resources. Large wind plants involving variable speed interior permanent magnet (IPM) synchronous generators and increasing level of wind power penetration in modern power system is becoming an engineering challenge throughout the world. The conventional wind generators are induction machines with cage-rotor and doubly fed wound-rotor types having small and limited wind power production per unit. These induction wind generators are operated at fixed super synchronous speed by intricate mechanical control of wind turbines. In wind power generation systems, variable-speed generation systems are more advantageous than the fixed-speed systems due to improved wind energy production, large capacity generators and reduction of flickers. Using IPM wind generator system, the wind turbine can be operated at its maximum power production point for various wind speeds by adjusting its shaft speed to its optimal generated electrical power from wind energy. Design, development and testing of a set of IPM wind generators are proposed in this proposal to take advantage of high efficiency and high power factor, compact size, large rating, high controllability, stable operation, built-in additional reluctance torque and low cost. The proposed IPM wind generator system will yield maximum output power while taking into account the wind turbine characteristics and constraints of power electronic converters. Two proto-type high efficient IPM wind generators are

当前增强的环境意识、积极的经济条件和技术发展的共同作用，促使全球积极努力使风能成为可再生和可持续能源的关键组成部分。大型风力发电厂采用变速内嵌式永磁同步发电机，风力发电在现代电力系统中的渗透程度不断提高，已成为世界各国面临的工程挑战。传统的风力发电机是具有笼形转子和双馈绕组转子类型的感应电机，每台风力发电量小且有限。这些感应式风力发电机通过风力涡轮机复杂的机械控制以固定的超同步速度运行。在风力发电系统中，变速发电系统比定速发电系统更有优势，因为它提高了风能的产量，增加了发电机的容量，减少了闪变。采用IPM风力发电系统，通过调节风力发电机组的轴转速，使风力发电机组在各种风速下都能达到最大功率。本方案设计、开发和试验一套IPM风力发电机，具有高效率、高功率因数、体积小、额定值大、可控性强、运行稳定、内置附加磁阻转矩、成本低等优点。在考虑风力发电机特性和电力电子变流器限制的情况下，所提出的IPM风力发电机系统将产生最大的输出功率。两台原型型高效IPM风力发电机是
