提出了一种内置式永磁同步发电机的变速风力发电系统。IPMSG的电枢电流矢量根据发电机速度被最佳地控制，以便最大化来自风力涡轮机的发电功率。IPMSG由具有最大功率点跟踪的损耗最小化控制来控制，该最大功率点跟踪低于基本速度，其对应于低和中等风速，并且可以从风捕获最大能量。在对应于高风速区域的基本速度以上，应用电流和电压限制的最大输出控制，其中电流矢量被最优地控制，使得考虑到电流和电压的约束，输出可以变为最大。所提出的输出最大化控制是在没有机械传感器，如风速传感器和位置传感器。控制系统已经开发和几个实验结果表明，建议的风力发电系统的有效性。
This paper proposes a variable-speed wind generation system using an interior permanent-magnet synchronous generator (IPMSG). The armature current vector of the IPMSG is optimally controlled according to the generator speed in order to maximize the generated power from the wind turbine. The IPMSG is controlled by the loss-minimization control with maximum power point tracking below the base speed, which corresponds to low and medium wind speed, and the maximum energy can be captured from the wind. Above the base speed corresponding to the high wind speed region, the current- and voltage-limited maximum output control is applied, where the current vector is optimally controlled so that the output may become the maximum in consideration of the constraints of current and voltage. The proposed output maximization control is achieved without mechanical sensors such as wind speed sensor and position sensor. The control system has been developed and several experimental results show the effectiveness of the proposed wind generation system.
