风能作为一种可再生的清洁能源具有广阔的利用前景.我国风力发电起步晚,发展快,纵观世界发展风力发电很不均衡,技术利用有高有低,重视程度也不尽相同.由于世界能源危机越来越严重,风力发电引起了人们的重视.目前的并网型风力发电技术主要有双馈异步、永磁直驱、普通异步等三种技术.与传统的风力发电方式相比,变速恒频双馈风力发电技术具有能量利用效率高和发电质量好的优点.
但由于双馈风力发电机其转子式旋转部件,且采用变频供电,转子为双馈风力发电机的故障多发点.因此,为提高整个电机的发电质量,在转子设计上进行了特殊的处理,但从而也带来了转子线圈嵌线困难等一系列制造难题.
在本论文中着重探讨双馈风力发电机的工作原理和控制原理以及风力发电机转子的制造工艺等问题,并根据第一台样机试制过程中出现的问题提出解决方案,并对转子进行优化设计,以期达到简化制造工艺,提高生产效率的目的.

Wind power as a kind of renewable energy has wide utilization foreground. Wind power in China late start, and quick development throughout the world development wind power is very uneven, technology USES have high low, attention is not the same. Because the world energy crisis is more and more serious, wind power aroused people's attention. The current grid type of wind power technology are mainly doubly-fed induction, permanent magnet straight flooding and general asynchronous, three technology. With the traditional way of wind power compared to variable speed constant frequency doubly-fed wind power generation technology has the energy utilization efficiency and power quality good points.
But because doubly-fed wind-driven generator its rotor rotating parts adopt inverter power supply, and rotor for doubly-fed wind-driven generator fault multiple points. Therefore, in order to improve the whole quality of motor power, in the rotor design special process, but which also brings a rotor winding embedding difficulties and so on a series of manufacturing problems.
In this thesis focuses on doubly-fed wind generators' working principle and control principle and wind-driven generator rotor manufacturing processes, and according to the problems such as the first prototype problems appeared in the course of solutions, and on the rotor optimized design, so as to simplify the manufacturing process, improve the production efficiency purpose.
