永磁直驱式风力发电变流器仿真分析

摘要

Converter is a key component for direct-drive permanent magnet wind generator to connect to the grid. This article describes the topology and working principle of converters, and simulates the converter perfor-mance based on Matlab software. The results show that while the analog supply voltage or frequency or both change (s), the output voltage and the frequency of converters are able to maintain constant, which verifies the ef-fectiveness of the topology and the control strategy of the converter, and provides a certain reference for the devel-opment of converters.%变流器是永磁直驱式风力发电机接入电网的一个关键部件。本文介绍了变流器的拓扑结构和工作原理，应用Matlab软件针对变流器性能进行了仿真。结果表明：当模拟电源的电压、频率或者两者同时变化时，变流器输出的电压和频率均能保持恒定，验证了变流器拓扑结构和控制策略的有效性，为变流器的研制提供了一定的参考。
