Abstract

The present paper investigates the performance of a Wind Energy Conversion System controlled to operate as an Active Filter when unbalanced loads are supplied by the same feeder. The control strategy named ‘compensation by means of Combined Modulation’ [1] is applied. This control methodology has been designed to sink the harmonic currents injected by balanced Non-Linear Load, and the connection of unbalanced loads to the PCC results in additional harmonic current flows within the WECS components and other detrimental effects. This paper is intended to analyze these effects and to determine the unbalanced load conditions that can be withstood by the WECS without compromising the components' integrity.

不平衡负载条件下作为有源滤波器的风能转换系统
本文研究了当不平衡负荷由同一馈线供电时,风能转换系统被控制为有源滤波器的性能。采用了“组合调制补偿”的控制策略[1]。这种控制方法旨在吸收平衡非线性负载注入的谐波电流,而将不平衡负载连接到PCC会在WECS组件内产生额外的谐波电流和其他有害影响。本文旨在分析这些影响,并确定在不影响组件完整性的情况下,WECS可以承受的不平衡负载条件。
