摘要
针对风电系统单机容量不断提升带来的问题,如风轮尺寸过大、运输和安装困难,使用升压变压器造成系统成本高和可靠性低等,该文设计了一种多风轮中压风电系统并搭建实验平台进行验证。该文首先介绍了多风轮中压风电系统的传动链结构和变流器拓扑,提出机侧有源整流器和网侧H桥逆变器的控制方法;然后搭建系统仿真模型并基于仿真结果搭建实验平台,验证了多风轮中压风电系统的可行性和控制方法的有效性。综合实验平台包含硬件及各类软件,可用于电力电子多电平变流器的教学。
In response to the issues caused by the continuous increase in the capacity of wind power systems,such as the difficulties in transportation and installation due to oversized turbine dimensions,high system costs and low reliability caused by the use of step-up transformers,this paper designs a multi-rotor medium-voltage wind power system and builds an experimental platform for verification.Firstly,the wind turbine drive train structure and the converter topology are introduced.The generator-side active rectifier and the grid-side cascaded H-bridge inverter control methods are proposed.Then the system simulation model is built,and an experimental platform is also built based on simulation results.The feasibility of the wind turbine system and the effectiveness of the control methods proposed are experimentally validated.The comprehensive experimental platform is composed of both hardware and various software,and it can be used for the power electronic multilevel converter teaching.
