摘　　要：介绍了保护装置硬件电路的构成及其特点,并从软硬件两方面考虑抗干扰措施,采用比例式相量差动保护原理,运用递推傅氏算法测频,动态跟踪频率变化,实时调整采样率进行定点采样,并采用滤除衰减直流分量的傅氏算法,提高了数据精度。The hardware structure and its merits are detailed in this paper. Anti-jamming instrumentalities are taken both in hardware and software, and ratio differential protect principle is adopted. The data precision is improved with the methods of Recursive Fourier Arithmetic Frequency measure, Dynamic Frequency Tracking, sampling rate Real-time adjusting. At last, the software structure is given.

关 键 词：数字信号处理 发电机保护 傅氏算法
