| 摘 要： | 分布式发电(DG)是指在公共电力系统中的关键部位或在用电负载处使用小型发电机(组)供电的模式,合理发展分布式供电有利于节约能源和保护环境。文章提出单相双凸极直流发电机作为小型清洁能源分布式直流电源系统的主发电机,其结构简单、功率重量比高、转速高,可以起到简化系统、降低成本、提高可靠性的作用。首先介绍了该型电机的原理和构成方法,然后运用时步有限元法对发电机进行电磁计算,分析、比较了电励磁、永磁单相4极/6极(定子极数/转子极数)双凸极直流发电机和三相电励磁6极/4极双凸极直流发电机的外特性和功率曲线,以及电励磁单相4极/6极双凸极直流发电机的3种发电方式的外特性和功率曲线,最后分析并仿真验证了减小输出电压脉动的方法。

| Abstract: | Distributed Generation(DG) means the way to supply electric power by small-scale generators in some key parts of the public power system or near the electricity load.Proper development of DG is beneficial to economizing on energy consumption and protection environment.This paper proposes single-phase Doubly Salient Generator(DSG) as the major generator of the small-scale distributed DC power supply system due to the compact construction,high ratio between power and weight and high speed,which can simplify t... |
