摘要
以电励磁双凸极发电机为基础,建立了一套定桨矩直驱式非并网风力发电测试和实验系统。通过该系统,在风洞里测试了定桨距风力机的气动特性,为风力机气动特性的理论研究和实现风力发电系统的最大功率跟踪控制提供了实验依据。另外,在风洞实验结果的基础上,对转速反馈最大功率跟踪方法进行了建模仿真,仿真结果对设计和开发定桨矩直驱式风电系统具有很好的指导意义。
A fixed-pitch direct-drive stand-alone wind power generation system was designed, based on a novel brushless electromagnetic doubly salient （DSEM） DC generator. The aerodynamic characteristic of the wind turbine was tested with the proposed system, and the tested results offer an experimental support for maximum power point tracking （MPPT） control and some other considerations. Then, a simulation was carried out based on the previous experimental results and speed feedback MPPT scheme, which would provide a profound guiding significance in designing and developing the fixed-pitch direct-drive wind power generation system.
