摘　　要：着重介绍基于CPLD与DSP架构的智能变电站电网IED(Intelligent Electronic Device,智能电力监测装置)的硬件架构和软件流程。着重阐述了"高速A/D转换器+CPLD"在信号采集过程中的优势,以及多路信号如何通过CPLD被DSP选择。DSP对信号进行处理,并利用FFT算法的结果分析电网的功率因素和谐波含量。This paper introduce a simple structure of Intelligent Substation IED＇s hardware architecture and software processes based on CPLD and DSP. We focuse on high-speed AD ＋ CPLD architecture which plays an important role in the signal process and how multiple signals are chosen by CPLD. We use FFT algorithm combined with DSP which calculates the key parameters of the energy grid such as power factor and harmonic content.
