双馈风力发电机(DFIG)系统控制复杂,离线仿真与传统全实物的故障试验存在一定局限性。在控制功能强大的MATLAB/Simulink环境下构建基于dSPACE1007系统的双馈风力发电系统半实物实时仿真平台,解决可模拟绕组内部故障的实物电机、dSPACE与Simulink软件三方联调时的数据接口与控制问题。试验结果表明,该平台在DFIG定、转子匝间短路故障工况下,通过Control Desk界面可灵活改变控制参数及算法,实现电机绕组内部故障状态下的容错运行,为DFIG故障检测和容错控制研究提供硬件平台。

The control of doubly fed induction generator (DFIG) was complicated. Offline simulation and traditional fullsubstantial fault experiments had their limitations. A semisubstantial realtime platform of doubly fed wind generation based on dSPACE1007 was constructed in the environment of powerful MATLAB/Simulink. Data interface and control of debugging motors with winding faults, dSPACE and Simulink software together were solved. The experimental results indicated that the platform funtion well in the working condition of stator or rotor winding interrnal faults through changing control parameters and algorithms by control Desk, which provided hardware platforms for fault detective and fault tolerance of DFIG.
