【摘要】：提出了一种基于比例—积分—谐振(PIR)控制器,且适用于电流源型永磁直驱风力发电系统(CSC-DPMSG-WGS)的低电压穿越运行控制方案。根据所提出的方法,电网故障时,通过机侧变换器控制来限制风力发电机的电磁功率,以实现机侧和网侧的功率平衡;网侧控制器在正序旋转坐标系下采用PIR控制器同时对正负序电流进行无差控制,以消除两倍基频的功率波动,进而稳定直流电流。仿真与实验结果表明,所提出的控制方案在电网对称及不对称故障下均可有效降低直流电流波动,并实现电流源型永磁直驱风力发电系统的低电压穿越。
[Abstract]:A low voltage traversing operation control scheme for current source permanent magnet direct drive wind power generation (CSC-DPMSG-WGS) system based on proportional integral-resonant (PIR) controller is presented. According to the proposed method, the electromagnetic power of the wind turbine is limited by the control of the machine side converter in case of power network failure, so that the power balance between the machine side and the grid side can be realized. In order to eliminate the power fluctuation of double fundamental frequency and stabilize the DC current, the PIR controller is used to control the positive and negative sequence currents simultaneously in the positive sequence rotation coordinate system. The simulation and experimental results show that the proposed control scheme can effectively reduce the DC current fluctuation and realize the low voltage traversing of the current source permanent magnet direct drive wind power generation system.
