摘　　要：针对谐波干扰,本文提出了基于模糊PID控制和模型预测控制的并联有源电力滤波器的谐波抑制方法。模型预测电流控制值函数中的优化目标从有源功率滤波器提供的补偿电流转换为逆变器输出电压。根据逆变器输出电压参考值对应的电压矢量相位,缩小逆变器输出电压矢量参与滚动优化的范围,实现对谐波电流的控制。最后通过对船舶综合电力系统的建模,并对巡航和升平台2种工况进行仿真,通过模糊PID与模型预测控制有源电力滤波器分析谐波抑制前后的电压波形和谐波含量,证明了所提方法在电源电压畸变情况下能够显著改善电力系统的电压质量,具有较好的谐波抑制效果。Aiming at harmonic interference,a harmonic suppression method of shunt active power filter based on fuzzy PID control and model predictive control is proposed in this paper.The optimization objective in the model predictive current control value function is converted from the compensation current provided by the active power filter to the inverter output voltage.According to the phase of the voltage vector corresponding to the reference value of the inverter output voltage,the range of the inverter output voltage vector participating in the rolling optimization is reduced,and the control of the harmonic current is realized.Finally,through the modeling of the ship's integrated power system,and the simulation of two working conditions of cruising and rising platform,the voltage waveform and harmonic content before and after harmonic suppression are analyzed by fuzzy PID and model predictive control active power filter.It is proved that the proposed method can significantly improve the voltage quality of the power system under the condition of power supply voltage distortion.
