复合励磁同步发电机励磁控制系统设计

摘要：此论文介绍了复合励磁同步发电机的励磁控制系统。此系统是一种基于单片机的控制系统，结合数字控制技术经过检测出来的同步发电机的运行参数，进而调节励磁，而使同步发电机有稳定的输出电压。本文介绍了以前的同步发电机的励磁系统的缺点，这些同步发电机并不能给如今的工业和生活带来更高的效率和可靠性，所以本文就提到了复合励磁同步发电机的励磁系统。复合励磁同步发电机的励磁系统有更高的效率和稳定性，完善了之前同步发电机的很多缺点。首先分析了复合励磁同步发电机的研究背景和意义，与此同时，在此背景之内，也分析了国内和国外分别对复合励磁同步发电机的研究，讲述了为何要研究这复合励磁同步发电机的励磁系统。然后本文重点分析了该系统的基本结构、工作原理和运行特性，不仅如此，本文还设计了复合励磁同步发电机的数学模型。再之后本文就到了复合励磁同步发电机的硬件电路设计和软件电路设，最后，本文就设计了该系统的仿真和波形了。同时，为了提高该系统的可靠性，在设计中采取了相应的保护措施。实验结果表明：该系统具有良好的稳定性和动态特性。
