摘　　要：本文通过交流电压连续三点采样值的简单计算得出系统的频率 ,数据窗长只需三点 ,反映速度快 ,计算简单 ,能实时跟踪系统频率的变化 。This paper can easily calculate out the frequency of a system through continuous three points samping value of alternating voltage.The data window only needs three points.Its reaction rate is very quick and cacluation is quite simple.Thus it can track the variation of frequency in time,then meets the real-time needs of frequency measurement of power system.

关 键 词：电力系统 三点交流频率算法 数据采集系统 频率测量 频率跟踪
