摘　　要：针对数字化变电站对计量仪表网络通信接口的要求,设计了一种以基于DSP的站内以太网接口模块。该接口模块能够接收站内光纤以太网上符合IEC61850-9-1格式的数据,经数字信号处理器处理后得到实时电压、电流、频率等参数。经模拟现场实验,该接口模块能够与基于IEC61850的数字变电站网络实现无缝连接,准确、及时解析出各项电参数。随着数字化变电站建设的推进,也可作为其它IED接口设计的参考。According to the requirements of digital substation to the network communication in measurement, a new Ethernet interface module based on DSP is designed. The module can receive the stational optical fiber to meet the Ethernet IEC61850 -9 - 1 format data. After obtained by the DSP, processing time voltage, current, frequency data and various power parameters are obtained. Experiments show that the design meets the requirement of digital substation to the metering and has the ability to seamlessly link with IEC61850 substation network. With the development of digital substation, it can also be a reference for other IED interface design.
