摘要

介绍了一种基于双馈感应发电机(DFIG)与直流母线连接的船舶电流涡轮(MCT)系统。场定向控制(FOC)是DFIG-DC能量转换系统所选择的控制策略。在这种拓扑结构中，二极管整流器用于连接DFIG的定子和直流母线，而转子通过PMW逆变器连接到直流母线。通过对d轴和q轴转子电流的控制，分别保证定子频率和直流电压的调节。提出了一阶滑模控制器来控制转子电流。仿真和实验结果验证了所提控制策略的有效性。

Sliding mode control of a Marine Current Turbine driven DFIG-DC conversion system

This paper presents a marine current turbine (MCT) system based on a Doubly Fed Induction Generator (DFIG) connected to DC-bus. Field Oriented Control (FOC) is the control strategy chosen for the DFIG-DC energy conversion system. In this topology, a diode rectifier is used to connect the stator of the DFIG and the DC-bus, while the rotor is connected to the DC-bus through a PMW inverter. The regulation of the stator frequency and the dc voltage is ensured respectively through the control of d-axis and q-axis rotor currents. First order sliding mode controllers are proposed to control the rotor currents. Simulation and experimental results are presented to show the performance of the proposed control strategy.
