摘要
针对目前无线传感器风能采集效率低和传统最大功率点跟踪算法(MPPT)不适用于微型系统的现状,提出一种基于电阻仿真的无线传感器风能采集方法。重点研究了电阻仿真技术,通过负载阻抗来模拟风机的源阻抗,使得电源和负载之间能够达到良好的阻抗匹配,保证在任何运行风速下采集到的功率都是最大值,从而达到提高无线传感器风能采集效率、延长其工作寿命的目的。最后通过实验,验证了该方法的有效性。
In view of low efficiency of wireless sensor wind energy harvesting and the current situation that the traditional maximum power point tracking algorithm is not applicable to micro-systems, a wireless sensor wind energy harvesting method based on resistance simulation is proposed. The resistance simulation technology is studied. The source impedance of the fan is simulated by the load impedance, so that good impedance matching can be achieved between the power supply and the load to ensure that the power harvested at any operating wind speed is the maximum. Therefore, the wind energy harvesting efficiency of the wireless sensor is improved to extend their working life. Finally, the effectiveness of the method is verified by experiments.
