| 摘 要： | 文章提出了风力发电应用中具有LCL滤波器的网侧变流器的一种多环控制结构,该结构采用电压外环外加3个逐层利用的电流内环,实现稳定的直流电压以及电流的前馈解耦和单位功率因数控制;使用基于复功率理论的电压估计方法简化了电容电压的估计,免去了使用电容电压传感器;该方法在Matlab/Simulink仿真环境中实现并得以验证.

| Abstract: | The paper proposes a multiloop control scheme for the grid side converter with LCL-filter used in wind power generation. Within this scheme, three cascaded inner current loops along with an outer voltage loop are used to achieve stable dc-link voltage and currents decoupling and feedforward as well as the unity power factor control,and the capacitor voltage estimation is performed based on the complex power theory, resulting in a simplified estimation procedure and the omission of the transducers for the capacitor voltage measurement. Under the Matlab/Simulink environment, the proposed scheme is programmed, simulated and verified. |
