This article presents a new wind energy system using 2 five‐phase permanent magnet synchronous generators (PMSGs) controlled by a fifteen‐switch rectifier (FSR) topology for grid‐connected system. The 2 five‐phase PMSGs are connected to the DC link through a FSR; at its turn, the DC link is connected to the grid through a classical three‐phase inverter. In order to boost the control performance of the proposed wind system, a sliding mode control is adopted to control both generators‐side and grid‐side converters. The proposed control is tested under varying wind velocity and compared with a proportional‐ and integral (PI)‐based control system. The obtained simulation results show that the controlled variables follow their references independently of the wind speed fluctuations; and there is a significant reduction in the speeds overshoots by 100% and in the DC‐link voltage ripples by more than 78%. In addition, the total harmonic distortion (THD) of the generated current and grid current are reduced to 7.19% and 47.80% compared with PI regulators, respectively.

由2个新的15开关变频器控制的2台五相永磁同步发电机驱动的并网风能系统的滑模控制

本文介绍了一种新的风能系统，该系统使用2个由15开关整流器（FSR）拓扑控制的五相永磁同步发电机（PMSG）并网系统。2个五相PMSG通过FSR连接到DC链路；直流母线通过经典的三相逆变器连接到电网。为了提高所提出的风力系统的控制性能，采用滑模控制来控制发电机侧和电网侧变流器。所提出的控制在风速变化的情况下进行了测试，并与基于比例和积分（PI）的控制系统进行了比较。仿真结果表明，控制变量独立于风速波动而遵循参考值。速度过冲大幅度降低了100％，直流链路电压纹波大大降低了78％以上。此外，与PI稳压器相比，所产生电流和电网电流的总谐波失真（THD）分别降低到7.19％和47.80％。
