Abstract

As one of the most commonly used electric motors, induction motor (IM) frequently encounters unbalanced voltage supply when being connected with power system supplies. The unbalanced voltage can cause issues such as unbalanced motor current, torque ripples, and motor speed pulsations, reducing both efficiency and lifespan of motors. This paper addresses these issues by proposing a compensatory torque loop strategy. The effectiveness of the proposed method is evaluated through a field-circuit-control co-simulation of motors under various operating scenarios. The results demonstrate that the proposed strategy can significantly improve key performance metrics, achieving a reduction in torque ripple of up to 66 %, and nearly 50 % even under more challenging conditions—all without the introduction of additional compensation hardware.

不平衡电压源下带转矩环的异步电动机改进控制策略

感应电动机作为最常用的电动机之一，在与电力系统供电时经常遇到电压不平衡的问题。不平衡电压会导致电机电流不平衡、转矩波动和电机速度脉动等问题，从而降低电机的效率和寿命。本文通过提出一种补偿转矩回路策略来解决这些问题。通过电机在各种工况下的场路控制联合仿真，评估了所提方法的有效性。结果表明，所提出的策略可以显著提高关键性能指标，在不引入额外补偿硬件的情况下，将转矩脉动减少66%，甚至在更具有挑战性的条件下也能减少近50%。
