The Study of a Power Controller Based on PWM Converter

文章研究了一种基于PWM整流器的功率控制器。由三相电压型整流器在三相静止坐标系中的数学模型,导出其在两相旋转坐标系的数学模型,并在此基础上引入了基于电网电压前馈解耦的三相PWM整流器控制系统,实现对于有功电流和无功电流的单独控制,从而达到对于有功、无功功率控制的目的。

In this paper, a power controller based on PWM converter is analyzed. By the mathematical model of three- phase voltages in three-phase stationary frame type rectifier, the mathematical model in two-phase mathematical model of rotating coordinate system is derived, and on the basis of above analyses, a three-phase PWM converter control system which based on grid voltage feedforward decoupling control system is introduced. It realizes single control between active current and reactive current, thereby, achieve the purpose to control active power and reactive power.
