摘要
对开关磁阻发电机(Switched Reluctance Generator,简称SRG)在风力发电系统的应用进行了分析研究,重点分析了适用于风电场合的功率变流器、拓扑结构及合适的控制策略。利用功率变流器励磁,SRG可运行在很宽的转速范围内,有良好的调速性能。SRG作为飞机的启动/发电装置在高转速运行区域已经得到了成功应用,但在低中速运行区域的研究尚处于起步阶段。为了能对SRG的控制策略进行优化设计,建立了SRG系统仿真模型,并通过改变参数对系统的特性进行了研究。
It analyzes and researches the Switched Reluctance Generator（SRG） in wind energy application,mainly focuses on the power converter,topology structures and suitable control methods for wind power fields.Using the excitation of power converter,SRG can operate in a wide speed range with excellent speed modulation.Its application in high speed area such as start/generation for aircraft has been established;however the low/medium speed operation is still at an early stage of research.In order to achieve the optimized design of SRG control method,the simulation model is completed,and the system characteristic is also researched through changing the parameters.
