摘要
在三相电压型脉宽调制整流器d-q轴数学模型的基础上,对其矢量解耦控制策略进行了研究,提出了基于电流的状态解耦和电网电压前馈补偿的控制策略。仿真结果表明,采用此控制策略的整流器能够获得单位功率因数的正弦输入电流、稳定的直流输出电压和快速的动态响应,并能够实现能量的双向流动。
The vector decoupled control strategy based on the d-q mode for the three-phase PWM voltage rectifier was researched, a model based on current state decoupling and grid voltage feed-forward compensation control strategy was proposed. Simulation results showed that the sinusoidal input current with unit power factor, steady output DC- voltage and dynamic response, as well as bi-direction power flowing ability could be realized by the control strategy.
