【摘要】 提出了一种直驱式风力发电系统模拟实验平台设计方案,搭建了直驱式风力发电系统模拟实验平台。机侧变流器采用id=0的矢量控制策略,为了避免引入编码器,设计了滑模变结构无速度传感器观测转子转速与磁链;网侧变流器采用电压外环、电流内环结构的电压定向控制策略。实验结果表明,本直驱式风力发电系统模拟实验平台具有良好的动态性能与稳态性能。更多还原

【Abstract】 A design of simulation platform of direct drive wind power system is proposed,and the simulation platform of direct drive wind power system is built.The id=0 of the vector control strategies is used in the control of generator-side converter,in order to avoid inducing the encoder,a sensor based on sliding mode is designed to observe the rotor speed and flux;meanwhile,the voltage oriented control strategy based on the structure of voltage outer loop and current inner loop is used in the control of grid-side converter.Experimental results show that the designed simulation platform of direct-drive wind power system has good dynamic and steady state performances.更多还原
