摘　　要：随着人类对能源可持续发展问题的日益重视,风能的利用正变得越来越重要。因此,对风力发电关键应用技术的研究成为国内外风力发电研究的热点。首先,通过对恒速恒频和变速恒频两种系统技术对比,确定了变速恒频系统在风力发电中的优势地位,然后对变速恒频系统的应用控制技术进行了全面的分析和研究,主要包含交流励磁双馈电机、永磁同步发电机技术和相应的控制策略等。研究结果表明,变速恒频风力发电技术无论是在输出功率方面,还是在运行效率方面都有着巨大的优势。With the increasing attention of the sustainable development of energy, the utilization of wind energy is becoming more and more important. Therefore, the research on the key application technology of wind power generation has become the focus of wind power generation research at home and abroad. Based on the contrast between the constant speed constant frequency system and variable speed constant frequency system, the paper concludes that the variable speed constant frequency earns the advantage in the wind power system. Furthermore, the research on the application of variable speed constant frequency system control technology is carried out, which consists of ac excitation doubly-fed motor, permanent magnet synchronous generator technology and the corresponding control strategy and so on. The results show that variable speed and constant frequency wind power generation technology has great advantages in both output power and operating efficiency.
