| 中文摘要:在同步发电机的励磁控制器中，移相触发模块用来触发整流桥中的晶闸管，使其控制角随着发电机端电压的变化而改变，从而达到自动调节励磁的目的，因此移相触发技术是自动励磁调节装置的一项关键技术。在介绍自动励磁控制器原理的基础上，论述一种基于DSP的移相触发电路的各个组成部分的设计和脉冲故障检测技术。这种数字移相触发器移相范围宽，灵敏度高，电路结构简单，安全可靠，可以推广应用于各种同步发电机的励磁控制。 |

| Abstract:In the excitation controllers of synchronous generator, the phase shifted trigger circuit is used to trigger thyristor and make control angle change along with the variety of voltage distributionacross thyristor in order to adjust excitation,so it is a key technology in automatic excitation controllers. The main function of excitation controllers was introduced, then recited the design of all parts of the DSP phase shifted trigger circuit. Finally, it introduced the pulse failure detection . This design method to be proved has a wide range of phase shife and high sensibility. At the same time the method has simple structure and safe. It can be applied to excitation control of differ synchronization generator. |
