摘要
永磁同步风力发电机具有重量轻、效率高和可靠性好的优点,已逐渐成为当前风力发电系统的主流选择。本文在通过对永磁直驱风力发电变流拓扑和阻抗源逆变器拓扑进行全面分析总结的基础上,对阻抗源永磁直驱风力发电系统的直通占空比插入方法和控制策略进行了详细的分析和介绍。最后,指出了阻抗源永磁直驱风力发电系统未来可能的发展方向。
Permanent magnet synchronous wind turbine with light weight, high efficiency and good reliability has gradually become the major choice of wind power conversion system (WPCS). This paper first introduces the topology of the permanent magnet direct drive WPCS and the impedance-source inverter. Second, the modulation of shoot-through duty ratio and the control method of impedance-source WPCS are classified and analyzed, Finally, some possible develop trends of impedance-source WPCS are pointed out.
