摘　　要：风力发电系统中发电机控制是比较重要的环节,各种风力发电机的控制算法在一定程度上依赖于准确的电机参数。首先分析了永磁同步发电机的数学模型及其控制策略,在分析一种基于锁相环模型和模型参考自适应原理的PMSG无速度传感器矢量控制方法的基础上,提出一种具有较强工程应用价值的永磁同步发电机的参数辨识方法。最后给出了各参数辨识的仿真模型和仿真结果。仿真研究结果验证了该控制方法的正确性和可行性。Generator control is very imptortant for wind power generation and all kinds of control algorithms for wind-driven generators depend on the accurate parameters of the motor to some degree.Firstly,the mathematical model and the control strategy of permanent magnet synchronous generator（PMSG）were analyzed.Secondly,after analyzing a novel sensorless vector control scheme of the PMSG based on phase-locked loop（PLL） and model reference adaptive system（MRAS）,a method to detemine the parameters of PMSG was proposed.Finally,simulation models and results of parameters of motor were presented.The validity and feasibility of the proposed identification technique is verified with the simulation results.
