【摘要】 励磁控制装置是发电机的主要控制装置之一,对于提高电力系统的稳定性及其动态品质有着重要的作用。随着电力系统的发展,不但对励磁控制装置的性能指标提出了更高的要求,而且现场工程师也对励磁控制装置调试接口的简单性和易用性提出了新的要求。本文根据这种要求,针对一个基于新型DSP芯片的励磁控制器,对USB接口的开发进行了研究。本论文首先对励磁控制技术及励磁控制器的通讯方式进行了分析,指出了励磁控制器对DSP技术和USB通讯方式的需求。其次,作为设计USB设备必需的工作,本文对USB2.0规范进行了较深入的研究。最后,也就是论文的主要工作,本文针对基于新型DSP芯片的励磁控制装置,在对不同的USB设计方案进行比较的基础上,选择了一种合适的开发方案,并分三个章节,分别较详细的论述了DSP和USB接口实现的硬件方案、在DSP芯片的软件开发环境下完成的固件编程、驱动程序开发的技术以及PC端应用程序编程的方法和步骤等内容。本论文对USB设备开发的各方面技术进行了研究,并针对一个基于DSP的励磁控制器,给出了具体和完整的实现。所讨论的USB开发技术,对其他的基于DSP的控制装置的USB接口开发也有一定参考意义。更多还原

【Abstract】 The excitation control system is one of the most important control systems of a generator. It has great effect on the stability and the dynamic quality of the power systems. With the development of power systems, it requires higher control precision of the excitation control system. And the engineer requires the excitation control system to have a simpler interface. According to this requirement, this paper studies the application of USB in an excitation controller based on DSP.Firstly, this paper analyzes the control and communication technology of the excitation control system, and points out the excitation controller’s requirement to DSP and USB. Secondly, as an essential work, this paper studies the USB2.0 protocol. Finally, and which is the central work, the paper gives a solution of the application of USB for an excitation controller based on DSP. It compares the solutions of USB interface, selects a fit one, and discusses the hardware solution, the firmware solution, the driver solution, and the software solution in PC. All the solutions are discussed in 3 chapters in this paper.This paper not only studies the design technologies of USB, but also gives a complete reach of USB interface for an excitation control system based on DSP. The technologies discussed in the paper may be also useful to other development of USB interface.更多还原
