摘要
本文介绍了一种基于TMS320F2812的励磁控制器,利用DSP片上外设实现了测频、采样和控制脉冲输出,从而简化了硬件结构,提高了可靠性和可维护性。文中给出了励磁控制器的部分硬件框图和软件流程,讨论了采取这些实现方法的原因,并通过动模实验对此方案进行了验证。该控制器已在现场运行,文章也给出了该控制器的部分现场实验波形。
A scheme of excitation controller based on the DSP F2812 is presented, The functions concerning with hardware, such as AD sample, pulses generation and frequency measurement are implemented with the peripheral on chip. Block diagrams on hardware and flow chart of part software are listed. Some detail on implementation is discussed. Dynamic simulations ona physical model verify the scheme. The controller has operated in a hydropower plant. Some curves of experiments onsite are also given.
