| 摘 要： | 提出了一种双级矩阵变换器(two stage matrixconverter,TSMC)直驱风力发电系统最大风能追踪控制策略。基于爬山法,通过引入中间变量实现对系统捕获风能状态进行判断,在此基础上,提出基于集成控制的最大风能追踪(maximum power point tracking,MPPT)算法。在Matlab中建立了TSMC风电系统仿真模型。仿真结果表明:新的MPPT算法通过对风力发电系统逆变级无功功率分阶段性的控制,不仅具有较好的准确性和稳定性,而且加快了系统捕获最大风能的速度。

| Abstract: | A two-stage matrix converter(TMSC) based control strategy of maximum wind power point tracking for direct-driven wind-power generation system is put forward.Based on hill climbing search,by means of introducing in intermediate variable the state of the captured wind power is judged,and on this basis a maximum power point tracking(MPPT) algorithm based on integrated control is proposed.By use of Matlab,a TMSC based simulation model of direct-drive wind power generation system is built,and simulation results show that through the phaseal control of reactive power in the inverters of direct-drive wind power generation system,the proposed algorithm is more accurate and stable,and the speed for capturing maximum wind power is quickened. |
