摘　　要：传统整流器的接入会给电网带来大量谐波和无功污染,为了削减电网侧的电压谐波分量,提高军用储能电源充电系统的功率因数,提出一种基于空间电压矢量PWM的新型闭环控制方法。在建立三相电压型PWM整流器的数学模型的基础上,分析了储能电源整流环节的双闭环控制结构,引用模糊逻辑对双闭环控制方法进行改进,利用模糊比例积分(PI)控制算法设计电流内环,系统可以实现PI参数的自适应调整。通过仿真验证了该方法的有效性,采用双闭环模糊PI控制的PWM整流器可以实现单位功率因数运行,保证输出的直流电压稳定,抗干扰能力强,具有良好的动态响应。The traditional rectifier will bring a lot of harmonics and reactive contamination to thepower grid,in order to reduce the voltage harmonic component side of the grid,improve the powerfactor of the military power charging energy storage system,this paper proposes a new control strategybased on the closed-loop space vector PWM control methods.On the basis of the establishment of thethree-phase voltage type PWM rectifier mathematical model,the double-close-loop control structure ofthe battery energy storage system rectifier links is analysed,optimized fuzzy double-close-loop controlmethod is designed for the fuzzy PI current loop control algorithm,which can optimize and adjusts theparameters of the system,and the effectiveness of the proposed method is validated by simulation.Thesimulation result showed that the use of double-close-loop fuzzy PI control PWM rectifier can achieveunity power factor operation,the output DC voltage is stable,the quality of anti-interference wasenhanced,and it also can ensure good dynamic response.
