摘要
介绍了采用双PWM电压源型全功率变流器的永磁同步风力发电控制系统,详细分析了永磁同步电机和变流器的数学模型。根据风速模型和风力机的特性,研究了在不同风况下的变流器控制性能。利用NI公司开发的LabVIEW软件及相关硬件,搭建了基于电压源型双PWM变流器的永磁同步风力发电控制系统实验平台,并完成了整个系统的软件和硬件设计。最后通过实验平台进行实验,验证了控制策略的有效性和可行性。
The double PWM full size power converter of PMSG wind power generation system was introduced.The mathematical model of PMSG and converter were analyzed detailly.Based on the wind speed model and the characteristic of wind turbine,researching the performance of converter under different wind condition.Make use of related hardware and LabVIEW software which is exploited by NI company,converter which based on voltage source doubled PWM of permanent magnet synchronous motor wind power generation system is put up,and finished all the design of hardware and software about it.In the end,by making experiment on this system verified the validity and feasibility of this system′s control strategy.
