| 摘 要： | 在大功率风力发电系统中，并网逆变器是实现电能馈送电网的重要环节。本文研究二极管箝位型三电平并网逆变器，建立了逆变器在两相同步旋转坐标系下的数学模型，采用了基于d-q坐标系的矢量控制策略，通过对并网电流的闭环跟踪控制，实现单位功率因数馈送电能。分析了逆变器直流侧电容不均压的原因，提出了一种基于模糊控制的中点均压策略。最后给出了仿真和实验验证结果

| Abstract: | In high-power wind power generation system,grid-connected inverter is important for energy conversion and transmission. The paper mainly focuses on the grid-connected diode-clamped three-level inverter, mathematic model of the converter is built in the two-phase rotating reference frame.The vector control system based on d-q rotating reference frame is employed to achieve transmiting power under uint power-factor by closed-loop control of grid-current.The reason why the voltage of capacitors at the DC side is unbalanceable is analyzed in detail, a neutral-point-balancing strategy based on Fizzy control is proposed. Simulation and experimental results are given to verify the proposed analysis and design at the end of the paper |
