| 摘 要： | 以PWM整流器双环控制系统中电流环设计为基础,分析并推导了一种输入无电压幅值和相位检测的系统模型重构方案.该方案在不改变系统主电路拓扑结构和影响系统动静态性能的情况下,减少了交流侧电压传感器.以电流环调节器为基础,通过估算得到了输入交流电压的幅值和同步相位.在Saber仿真平台上进行了仿真实验,得到了不同实验条件下的仿真波形,结果验证了这种设计方法的正确性和可行性.

| Abstract: | Based on the internal current control loop of the two closed-loop control schemes, a new model for system control scheme without the input voltage amplitude and phase detection was reconstructed to reduce the number of system sensors, remaining the system dynamic and static capabilities with no changing the main circuit topology. The amplitude and synchronous angle of input voltage were produced by the calculation through the current regulators. The waves were stimulated under different simulation condition on the Saber platform. The simulation results showed that this method is recommendable in designing tree-phase reversible PWM rectifier. |
