本文提出了一种使用内置式永磁同步发电机（IPMSG）的变速风力发电系统。 IPMSG 的电枢电流矢量根据发电机速度进行优化控制，以最大限度地提高风力涡轮机的发电功率。 IPMSG采用损耗最小化控制，MPPT低于基速，对应中低风速，可以从风中捕获最大能量。在高风速区域对应的基速之上，采用电流电压限制最大输出控制，在考虑电流和电压的约束下，对电流矢量进行优化控制，使得输出达到最大。所提出的输出最大化控制是在没有风速传感器和位置传感器等机械传感器的情况下实现的。控制系统已经开发出来，几个实验结果表明了所提出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 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 MPPT 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.
