摘要
介绍风力发电的发展状况,分析了风力发电的技术动态,说明可变速发电方式和风车大型化的优点。详述同步发电机配备大功率变频装置和双重励磁绕线式转子异步发电机配备电力变换装置的两种方式。今后风力发电将始终围绕着降低成本、提高系统稳定性和可靠性这几个要点,得到广泛应用,成为对国民经济有着举足轻重影响的产业。
Development of the wind turbine generator was introduced, technical tendency of it was analyzed and advantages of variable-speed generating method and macro-scale operation＇technology were summarized. The synchronous generator equipped with large power frequency transducer and double fed induction generator equipped with power transmition device were described, becoming two types of key control apparatus. The wind turbine generator from now on will focus on cost decreasing, stability/reliability-increasing, which will be widely used and play an important role in the development of the national economy.
