摘要
目前,同步发电机静止式励磁大多采用相位控制方式,但这种方式存在一些缺陷,直接影响了系统的性能。详细分析了相位控制方式存在的不足,提出了一种新型的PWM控制方式,并论述了基于数字信号处理器TMS320F2812的同步发电机励磁调节器的硬件和软件设计。利用TMS320F2812丰富的片内外设和强大的处理能力,该装置不但能进行精确的励磁控制,而且能很容易的实现通讯、人机接口等附加功能。此装置进行的直接带负载运行实验,得到了较为满意的效果。
Presents a novel PWM-contmlled excitation controller for synchronous generator in order to overcome the inherent disadvantages of traditional phase-controlled excitation controller. The design of the hardware and software of the controller based on TMS320F2812 is also introduced. In this design, by making use of the abundance on-chip peripherals and powerful processing ability, not only the precise excitation control is reached, but also the add-in communication and human-machine interface functions are accomplished. Satisfying results are got with stand-alone load.
