摘　　要：介绍基于交流同步采样和傅里叶算法的三相功率计算方法,采用TI公司的32位定点DSP TMS320F2812为控制器的CPU,根据非正弦周期信号的无功功率理论,固定采样点数,适时测量工频周期,自适应调整采样间隔,解决了同步采样问题。采用快速傅里叶算法,实现了对无功功率和有功功率的准确测量,准确跟踪系统无功变化,使系统无功功率动态实时补偿。The three-phase power calculation method based on AC synchronous sampling and Fourier algorithm is introduced, the way which adopted 32 bit fixed point DSP TMS320F2812（produced by TI company） as the controller＇s CPU, fixed sampling points, timely measured power frequency cycles, adaptively adjusted the sampling interval to solve the problem of synchronous sampling, according to non-sinusoidal periodic signals of reactive power theory. The fast Fourier algorithm is used to realize its reactive power and active power of accurate measurement and accurate tracking of reactive power changes of system, and make the system reactive power to dynamic real-time compensation.
