摘要
根据目前电力谐波监测系统开发的现状,设计了一种以TMS320F2812DSP和LPC2292ARM双CPU为核心,结合高速同步AD转换器、并行双口RAM等硬件组成的监测系统。并阐述了主要功能模块的硬件设计和原理,实现了FFT算法。实验结果证明了本系统的可行性与精确性,具有很好的实用价值。
According to the current research situation of the monitoring system of power system harmonic, we design a new type of power quality monitor based on dual TMS320F2812DSP and LPC2292ARM combined with the hardware of high-speed simultaneous-sampling AD converter,parallel dual--port RAM and other hardware components. The hardware design and principle of the main functional model were expounded and the FFT algorithm was realized .The feasibility and the accuracy of the system as well as the practicality were proved in the experiment.
