| 摘 要： | 对三相电压型PWM整流器运用空间矢量脉宽调制策略进行运行研究.首先建立PWM整流器的在abc坐标系数学模型,运用坐标变换推导dq坐标系下的数学模型.运用前馈解耦策略,得到整流器的双PI闭环控制结构,同时给出网侧电感和整流侧电容的计算公式.采用基于SVPWM固定开关频率电流控制策略,设计三相电压型PWM整流器.运用Matlab软件中Snmulink电力系统动态库仿真,结果表明,该方法使整流器在单位功率因数下运行,负载突变时,同样能保证系统的稳定性与快速响应,为工程实际应用提供了参数运算依据.

| Abstract: | The three-phase voltage-source PWM rectifier is researched on space vector pulse width modulation strategy.The mathematical model of PWM rectifier is built on three-phase stationary abc coordinate system abc.The mathematical model on two-phase rotating dq coordinate system is derived from coordinate transformation.PI controller in the two closed-loop is designed in the use of feed-forward decoupling strategy.The inductor of network side and capacitance formula are given.The model of the whole system is built and simulated in Matlab2009b/Simulink software of power system dynamic libraries based on fixed switching frequency current control strategy.The results of simulation show the rectifier can run in the condition of high power factor,and ensure the system is stable and fast when the load change.The paper provides the basis for computing parameters on the practical applications in engineering. |
