【摘要】 提出了一种应用于直驱风力发电系统(DDWPS)中的模型参考自适应系统(MRAS)无速度传感器永磁同步发电机(PMSG)控制方案。指出对于DDWPS,基于MRAS的无速度传感器技术能够省去转子速度传感器,节省系统成本,提高系统的可靠性。在Matlab7.1/Simulink中建立了基于S函数控制的DDWPS仿真模型,仿真结果表明该方案应用在DDWPS中的PMSG上能够满足系统运行的要求,动静态性能比较理想。在试验室17kW试验平台上验证了该方案的可行性。更多还原

【Abstract】 A MRAS speed sensorless control method applied in permanent magnet synchronous generator(PMSG) in direct drive wind power system(DDWPS) is proposed.This method does not need the speed sensor and can reduce the cost of the system as well as enhance the reliability.A simulation model of the DDWPS is built in Matlab7.1/Simulink.The results of the simulation show that this speed sensorless method applying in the DDWPS can meet the request of the system operation.The steady and dynamic performances are both satisfying.To verify the performances in practice,an experiment is done on the 17 kW DDWPS experiment platform.更多还原
