摘　　要：电励磁同步电机具有调速范围宽、过载能力强、功率因数可调等优点,广泛应用于大功率传动领域。为此介绍一种背靠背式电压源型变频器的系统结构,及两种基于电流频率(IF)控制和滑模观测器(SMO)控制相结合的无速度传感器矢量控制方案。动模平台的实验结果表明两种控制方案都能够实现电励磁同步电机无速度传感器的变频启动与调速功能,但方案二具有更高的功率因数和实用性,为高压大功率传动应用领域提供更好的技术保障。Electrically excited synchronous motor has the advantages of wide speed range,strong overload capability and adjustable power factor,it is widely used in the field of high power transmission.So the system structure of a back to back voltage source converter and two kinds of speed sensorless of vector control schemes based on combination of current frequency(IF)control and sliding mode observer(SMO)control were introduced.The experimental results of dynamic simulation platform show that both control schemes can realize the functions such as variable frequency starting and speed regulating for the speed sensorless of electrically excited synchronous motor.But scheme two has higher power factor and practicability,it can provide better technical support for the applications of high voltage and high power transmission.
