摘要

基于电流源变换器(CSC)的风能转换系统是下一代风力发电系统的理想选择。为了确保控制目标，现有的基于csc的风力系统使用了大的直流电流。在这项工作中，提出了直流电流减小方案。它保证了控制目标并减少了直流电流，从而显著降低了功率损耗。提出了直流链路电流减小方案，并通过仿真验证了其有效性。

DC-Link Current Reduction for Current Source Converter-Based Wind Energy Conversion System

The current source converter (CSC)-based wind energy conversion system is a good candidate for next-generation wind systems. To ensure control objectives, a large dc-link current is used in existing CSC-based wind systems. In this work, a dc current reduction scheme is proposed. It ensures control objectives and reduces the dc current, resulting in a significant power loss reduction. The proposed dc-link current reduction scheme is presented, and its effectiveness is verified by simulations.
