摘　　要：目前广泛使用的同步发电机数字励磁调节器使用简单的单片机控制,采用PID+PSS控制策略,励磁调节器体积大,模块间干扰大,速度低,可靠性差。针对此问题,设计开发了基于DSP(TMS320F2812)的数字励磁调节器,采用PID+PSS+NOEC综合控制策略,实现了大部分调节功能与控制功能的软件化。实验证明,把DSP用于同步发电机数字励磁调节器中,简化了硬件结构,降低了成本,提高了系统可靠性,同时可以实现优良的控制效果。The widely used synchronous generator digital excitation regulator is controlled by one-chip computer and adopts PID ＋ PSS control strategy. Excitation regulator has great bulk with low speed and reliability,and its modules interfere each other. According to the problems,a digital excitation regulator based on DSP （TMS320F2812） is designed and explored. It adopts PID ＋ PSS ＋ NOEC, the synthetic control strategy, which softwarizes most adjusting and controlling functions. Experiments show that applying DSP to synchronous generator digital excitation regulator simplifies hardware structure, reduces cost, improves reliability and realizes good control effect.
