摘要
通过升压变压器并网的永磁直驱风力发电系统越来越不能适应机组容量日益增大的风电发展趋势。对此提出一种新型无变压器的高压永磁风力发电系统,给出主电路关键参数的计算方法,并对其中H桥级联逆变器的脉宽调制(PWM)方法进行了介绍,最后搭建了一个基于三级级联的无变压器风力发电系统试验平台,验证了该方案的可行性。
At present, permanent magnet direct-driven wind power generator system with traditional step-up transformer cannot meet the development trends of the fast growing unit capaeity.A new high-voltage permanent magnet wind power generator converter system without transformer is proposed.The key parameter calculation method of the main circuit is presented, and the pulse width modulation (PWM) method of the H bridge cascaded inverter is introduced. Finally, the test platform based on a three stage H Bridge cascaded wind power generation system without transformer is built.The feasibility of the scheme is validated.
