摘要:

提出了一种无传感器直驱式永磁同步风力发电机控制系统的转子速度估算法。该算法可由简单的定子磁通方程推导，且只需检测定子电压和电流。定子磁通估算通过基于定子电压模型的可编程低通滤波器而设计，建立了基于递归最小二乘法的电机转速辨识模型，并将实时辨识的电机转速用于转子位置观测和转子磁场定向矢量控制。仿真结果表明，实现了最大功率跟踪控制，验证了控制算法的有效性和可行性。

Abstract:

A rotor speed estimation algorithm in a direct vector controlled permanent magnet synchronous generator wind energy conversion system is proposed. The method is based on a simple equation obtainer from stator voltage and current. Stator flux information required by the speed estimator is obtained using the stator voltage equation by implementing a programmable low pass filter. The constant gain recursive least squares algorithm is adopted. Then, the rotor position obtained based on the proposed method are used in the rotor-flux oriented vector control of PMSG. The simulation result shows that the control strategy realizes maximum power point tracking control, which verifies the validity and feasibility of the theoretical model and control strategy.

Key words: permanent magnet synchronous generator speed estimation wind energy conversion systems sensorless control maximum power point tracking control
