摘要
为立式风力发电系统设计了新型集风立式风机、多绕组变极发电机、异步的数据采集系统、发电机和风速控制系统。新型集风立式风机克服了传统三叶桨风力利用率低、发电功率低、保护性差的特点。利用DSP触发FPGA控制外置两片AD7656可以达到高精度数据采集和高实时数据处理以及控制的并行化。双DSP架构通过双口RAM共享存储,提高了实时通信的吞吐率,同时将实时任务和耗时的显示等人机交互任务分离。一方面在PLC里存储模糊规则表,实现对集风板的模糊控制,进而调节风速;另一方面通过多绕组变极发电机的绕组和励磁方式切换,来保持发电机输出电压频率、幅值和相位的稳定,解决了风电并网的难题。
A new wind-collected vertical-axis wind turbine, multi-winding pole-changing generator, asyn- chronous data acquisition system, generators and wind speed control system are designed for vertical wind power generation system. The new wind-collected vertical-axis wind turbine overcomes the shortcoming of the traditional horizontal-axis wind turbine with low wind energy utilization, low power generation, vulnerable under fierce wind. Using DSP triggering FPGA to control two AD7656 chips can achieve the parallelism performance of high-precision data acquisition and real-time data processing or control. Dual-DSP architecture can separate the real-time tasks and time-consumed tasks such as display and ete to improve the real-time performance. Using fuzzy control rules stored in the PLC to adjust wind speed through the position of wind-collected board and the multi-winding switching can assure the stability of frequency and amplitude and phase of the generator to simplify the wind power to join the power grid.
