摘要
设计了一种基于TMS320F2812 DSP电力参数实时检测系统。采用ADS8364对6路信号同时采样,利用复序列FFT算法得到各种电力参数,可由CAN总线与上位机实时传输数据,实现对电力系统的实时、准确的参数测量和数据分析。采用了硬件锁相环技术,可更加有效实现同步采样,提高了采样精度。
A real-time detection system of power parameters based on TMS320F2812 DSP is designed in this paper. It samples 6-way signals at the same time by usingADS8364, and then works out different power parameters by means of the complex sequence FFT algorithm. The real-time data can be transmitted by the CAN bus and PC so as to realize measurement of the accurate real-time data of the power system and carry out the fanh analysis. Application of the hardware PLL technology can achieve the synchronous sampling more effectively and help improve the sampling accuracy.
