摘要
电机作为一种重要的电力电子负载,在工业应用中具有十分重要的应用价值。利用电力电子变换器模拟电机特性,进而测试电机驱动器的性能,这是一项十分重要的过程。采用一种双向能量流动的三相背靠背双PWM变换器作为虚拟电机结构,通过电机侧PWM变换器跟踪实际电机电流波形来模拟实际电机运行,再通过网侧PWM变换器将能量与电网进行交互,能够达到虚拟电机的效果,对电机驱动器进行性能测试。实验结果证明了所提方案的有效性。
As an important power electronic load,motor has very important application value in industrial application.It is a very important process to use power electronic converter to simulate motor characteristics and then test the performance of motor driver.A three-phase back-to-back Dual PWM converter with two-way energy flow is used as the virtual motor structure.The motor side PWM converter tracks the actual motor current waveform to simulate the actual motor operation,and then the energy is interacted with the power grid through the grid side PWM converter,which can achieve the effect of virtual motor and test the performance of the motor driver.Experimental results show the effectiveness of the proposed scheme.
