摘　　要：电力电子装置工作时产生无功功率,导致电流增大和视在功率增加,对公用电网造成不良影响。为此,本文提出基于离散集模型预测控制的电力电子装置自动无功补偿方法。仿真结果证明,该方法不仅减少计算量,还能限制谐波含量,使电力电子装置达到最佳控制效果。Power electronic devices produce reactive power when they work, which leads to the increase of current and apparent power, which has a negative impact on the public power grid. So, this paper proposes an automatic reactive power compensation method for power electronic devices based on discrete set model predictive control. The simulation results show that the method not only reduces the amount of calculation, but also limits the harmonic content, which makes the power electronic device achieve the best control effect.
