基于双馈感应发电机的变速风电机组系统设计Design of Variable Speed Wind Turbine System Based on Doubly-fed Induction Generator摘 要现如今随着时代的发展，科技的进步，各个工业部门技术快速的提升发，致使可用能源急剧下降并形成其短缺的情况，而且环境也在很大程度上遭到破坏。所以，每个国家都将注意力放在了开发新能源以及可再生能源方面。而对于当今世界来说，风力发电在研发程度、科技水平以及开展的规模上是仅次于水力发电的。而且它还是永久性清洁能源，这也是其与化石能源的差异之一。所以相对于后者，它可以为当今社会生产的能源需求提供一个支柱。世界上的发展中国家和发达国家在风力发电这方面的关注程度正在不断的提升，且都在孜孜不倦的研发在科技水平上也在不断的进步。通过分析双馈型风力发电机组的书面理论及数学模型，开始探讨风力发电时双馈型变速风力发电机的作用范围。利用 MATLAB/Simulink 工具箱建立仿真模型，得出风电机组在风速波动时和电网故障时输出特性曲线，并验证该系统设计是否满足并网发电要求。关键词：风力发电；双馈感应发电机；MATLAB/Simulink 仿真ABSTRACT Nowadays, energy shortage and environmental pollution are becoming more and more serious, and countries have stepped up their development of renewable energy. Wind power generation is the most mature and most widely developed form of power generation. Unlike fossil fuels, wind energy is a kind of permanent clean energy that can provide long-term and stable energy supply. In this regard, the wind power generation has received the attention of all countries and vigorously developed, and continuously innovated in the technology.By analyzing the theory and mathematic model of the double-fed wind turbine generator, the application of double-fed variable speed wind generator in wind power generation is studied.Based on MATLAB/Simulink toolbox, the simulation model is established to obtain the output characteristic curve of wind power unit in the wind speed fluctuation and power grid failure, and verify whe...
