摘　　要：结合80C196KC的运算速度快、集成度高、功能强大特点,设计了一种PWM型数字励磁调节器,并且提出了一种采用三相一点交流采样和直流采样相结合的新型采样方式,该方式具有采集快捷,运算量小的特点。为了证明采样方式的正确性,以及硬件电路的可靠性,我们在T2S-40型发电机上进行了实验,最终证明其性能指标能够满足三类发电机组稳态和瞬态性能指标的要求。该调节器还具有体积小、功能强、操作方便、显示明确的特点,在实际中具有很强的实用价值。We designed the digital PWM-regulator for generator excitation based on 80C196KC. The microprocessor operates rapidly, integrates highly and has the strong function. In the article, we put forward a new sampling method, i.e. the AC-sampling and the DC-sampling method. In the AC-sampling method, we collected the instantaneous voltage and current values of the three phases. This sampling methods has the many advantages, such as shortcut ,the easy operation etc. In order to prove the regulator, we experimented on third-class. The regulator has t operation, the clear display the T2S-40 dynamotor many advantages, such and practicality. correctness of the sampling method and the hardware of the and find the steady and the instantaneous index achieve the as the small dimension, the strong function, the convenien
