基于反馈线性化PMSG风力发电系统控制

Feedback Linearization Control of PMSG-based Wind Power Generation System

在分析了PMSG(永磁同步发电机)风力发电系统数学模型的基础上,以额定风速以下风能的最大捕获为目标,采用反馈线性化结合最优跟踪控制方法设计了PMSG风力发电控制系统,并基于VisSim的直观界面和强大的数学功能,建立了PMSG风力发电控制系统的仿真模型。仿真结果表明,风速在额定风速以下大范围变化时,反馈线性化结合最优跟踪控制方法在能有效实现风力发电机组的最大风能捕获。

In order to capture maximum energy under rated wind speed, a PMSG-based wind power generation control system was designed, integrating feedback linearization and optimal tracking control. Simulation results indicate that the proposed control method can effectively implement maximum energy capture under rated wind speed, even if the wind speed changes in a large range.
