摘　　要：设计了基于FPGA(现场可编程逻辑门阵列)的数字电能表接收及解码模块。通过调用MAC IP核并对其进行配置实现遵循IEC 61850协议包的接收,采用Verilog HDL语言编写解码模块对接收到的数据帧进行实时解码,提取出瞬时电流、电压。在FPGA芯片上仿真结果表明,采用该方案能实时准确地解析协议包并完整存放采样值。Modules based on FPGA（field programmable logic array） were cleslgnea tor receiving and processing of digital electric energy meter. Through receiving the IEC 61850 protocol packets by calling the MAC IP core, and decoding received data frame by using Verilog HDL language for writing decoding modules, the instantaneous voltage and current value is acquired. The simulation result in the FPGA chip shows that this method can real-time and accurate decode the protocol packets and store the voltage value and current value completely.
