摘要

本文对三种变流器拓扑结构进行了比较，用于永磁同步发电机海上风力机的交流-交流转换阶段。WECS(风能转换系统)基于四个阶段:输入滤波器，交流-交流转换器，三相高频变压器和全桥二极管整流器。本文选择了传统背靠背变换器、矩阵变换器和间接矩阵变换器三种拓扑结构。本文采用解析模型和数值模拟的方法来评估wcs效率和功率密度随变压器工作频率的变化规律。研究发现，在变压器频率从100[Hz]到10[KHz]的范围内，直接矩阵变换器拓扑是最有效的拓扑，具有最高的功率密度。一般来说，背靠背转换器拓扑在所考虑的频率范围内具有最低的效率和功率密度。

Comparative study of the efficiency and power density of offshore WECS with three-phase AC-link

In this paper three converter topologies are compared for the AC-AC conversion stage of an offshore wind turbine with permanent magnet synchronous generator. The WECS (Wind Energy Conversion System) is based on four stages: an input filter, an AC-AC converter, a three-phase high-frequency transformer and a full-bridge diode rectifier. The conventional back-to-back converter, the matrix converter and the indirect matrix converter are the three selected topologies. Analytical models and numerical simulations are considered in order to evaluate the WECS efficiency and power density as a function of the operational frequency of the transformer. It was found that for range of transformer frequencies from 100[Hz] to 10[KHz], the direct matrix converter topology was the most efficient topology and had the highest power density. In general, the back-to-back converter topology presents the lowest efficiency and power density in the range of frequencies considered.
