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d SPACE1007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、d SPACE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。 Doubly-fed wind turbine (DFIG) system control complex, off-line simulation and traditional all-real fault test there are some limitations. The real-time simulation platform. of doubly-fed wind power generation system based on d SPACE1007 system is built in the powerful MATLAB / Simulink environment to solve the real-time motor which can simulate the internal fault of the winding. The data interface between the SPSP and Simulink software is Control the problem. The experimental results show that the platform. can flexibly change the control parameters and algorithms through the Control Desk interface under DFIG and rotor inter-turn short circuit fault conditions to realize fault-tolerant operation in the fault state of the motor windings, and to study the DFIG fault detection and fault-tolerant control Provide hardware platform.
