Unity power factor control of a direct-driven permanent magnet synchronous wind-power generator
Pages: 13-20
Year: Issue:  6
Journal: Electric Machines and Control

Abstract: 针对采用传统矢量控制的直驱永磁同步风力发电机存在电机运行功率因数降低的问题,提出一种适用于采用双脉宽调制变换器并网的永磁同步发电机单位功率因数运行控制策略.所提方案在实现永磁直驱风电系统最大风能捕获控制的基础上,通过控制电机侧变换器使电机d轴控制电压为零来实现永磁同步发电机的单位功率因数运行控制.系统仿真和实验结果表明:采用所提运行控制策略可有效实现永磁同步发电机的单位功率因数运行,有助于减小电机...
