摘要

通过风能转换系统(WECS)发电预计将在世界发电矩阵中提供相当数量的电力。在这种情况下，配备全尺寸电力电子转换器的变速风力涡轮机允许WECS在每个时刻接近其最大功率点运行。此外，现代电源转换器保证了高功率质量，高转换效率水平，可靠性和灵活性。这项工作回顾和比较两种类型的调制方案，以两种新颖的能够驱动Δ-switch整流器。本文的理论分析是基于一个WECS应用。电路仿真和实验结果验证了所考虑策略的有效性。结果表明，其中一种新的次优调制模式在不需要精确的扇区识别方案的情况下具有非常高的性能。

Comparison of modulation strategies driving a three-phase PWM delta-switch rectifier in wind energy conversion systems applications

Energy generation through wind energy conversion systems (WECS) is expected to supply a considerable amount of electricity in the world's generation matrix. In this context, variable-speed wind turbines equipped with full-scale power electronic converters allow a WECS to be operated close to its maximum power point at each time instant. Furthermore, modern power converter guarantee high power quality, high conversion efficiency levels, reliability and flexibility. This work reviews and compares two types of modulation schemes to two novel ones that are able to drive a Δ-switch rectifier. The presented theoretical analysis is based on a WECS application. Circuit simulation and experimental results verify the operation with the considered strategies. It is shown that one of the novel sub-optimal modulation patterns presents very high performance without the need of a precise sector identification scheme.
