摘　　要：针对现在电力系统中励磁控制器数据处理慢、传输效率低的问题,本文提出了一种基于TMS320C240xa的DSP微机励磁控制器的设计方法,文中详细介绍了励磁控制器的模拟量输入单元、同步测频单元、数字量输出单元和移相触发单元的硬件设计。经过实验验证,这种基于DSP的微机励磁控制器具有硬件简单、软件灵活、抗干扰能力强、控制精度高的特点,可以推广应用于各种同步发电机的励磁控制。Aiming at slow date processing and inefficient transfer of excitation in power system, An DSP excitation controller design method of excitation control system based on TMS320C240xa is introduced in this paper. Analog input circuit, measurement of frequency circuit, digital output circuit and phase shift trigger are described in detail. This design method to be proved has a simple hardware and flexible software. At the same time the method has strong anti-jamming ability and high control precision. It can be applied to excitation control of differ synchronization generator.
