分类算法在同步风力发电机矢量控制系统的应用
|
摘要
提出了一种基于直驱永磁同步发电机(PMSG)的独立式变速风力发电机运行的新型分类控制算法,讨论了具有最大功率追踪的发电机侧转换器的独立控制方式,使得输出电压和频率控制器能够处理可变负载。通过直流斩波器控制,可以在阻尼电阻中消耗潜在的过剩功率并保持直流链电压,同时给出了直流总线的动态表示和小信号分析。仿真结果表明,控制器可以在不同的风荷载条件下提取最大功率并调节电压和频率,并且控制器表现出较好的动态调节性和稳态性。
A new classified control algorithm for the operation of independent variable speed wind turbines based on direct drive permanent magnet synchronous generator(PMSG) was proposed. The independent control method of generator-side converter with maximum power tracking was discussed, which makes the output voltage and frequency controller handle variable load. By DC chopper control, the potential excess power can be consumed in damping resistance and the DC link voltage can be maintained. The dynamic representation of DC bus and small signal analysis were given. The simulation results show that the controller can extract the maximum power and adjust the voltage and frequency under different wind loads, and the controller shows good dynamic regulation and steady-state.
