摘　　要：在介绍合并单元服务器模型的基础上,描述了一种基于现场可编辑逻辑门阵列(FPGA)的电子式互感器智能合并单元的具体实现方法。根据FPGA的模块化编程和多任务处理的特点,该方法在单片FPGA内实现采样脉冲同步,数据采集,采样值处理,以及以太网控制芯片驱动和数据帧发送。本合并单元能够传输符合IEC61850-9-1和IEC61850-9-2规约的数据帧,两种数据帧的传输可以根据实际需要进行切换。运用MMS Ethereal软件对本合并单元发送的数据帧进行捕获和分析,结果表明该合并单元具有较高的灵活性和较强的实用价值。Based on introducing the server model of merging unit, this paper describes a realization method of intelligent merging unit of electronic transformer on the basis of FPGA in detail. According to the features of modular programming and multitasking of FPGA, this method realizes sample pulse synchronization, sample values （SV） receiving, SV processing, Ethemet controller driving, and SV transmitting in single chip FPGA. Data frames transmitted by the merging unit correspond with the protocol of IEC61850-9-1 and IEC61850-9-2. Transmission of the two kinds of data frames can be switched in terms of actual needs. The data frames are captured and analyzed by MMS Ethereal software, and the results demonstrate the merging unit has high flexibility and utility value.
