为了满足小型风力发电技术的研究需要,分析了风力机的运行特性及采用直流电动机转矩闭环控制模拟风力机的可行性,设计了基于直流电动机的小型风力机模拟器,并给出了采用西门子调速系统驱动直流电动机的模拟器实现方案及基于永磁同步发电机的测试系统,进行了实验研究。实验结果表明,所设计的风力机模拟器可以模拟小型风力机的转矩-转速特性和功率-转速特性,为在实验室条件下研究风力发电技术的原动机问题提供了一个实用的解决方案。
In order to meet the requirements of small wind power generation research,the operation principle of a wind turbine and the feasibility of its characteristic simulation using closed-loop control of DC motor torque were analyzed.The DC-motor-based simulator of a small wind turbine was designed,and its implementation scheme in which DC motor was driven by SIMOREG DC MASTER 6RA70 and the test system with PMSG（permanent magnet synchronous generator） were presented.Experimental results show that the wind turbine simulator proposed is able to simulate the torque-speed and power-speed characteristics of a small wind turbine,and provides a practical solution of the prime mover for the research on the wind power technology in laboratory.
