For the more effective application of modular programming and multi-tasking of FPGA, the de-sign of an intelligent substation merged cells is proposed using field programmable logic array (FPGA) as a hardware framework. By configuring Nios II soft-core processor and associated interface on the FPGA chip, the merger unit completes sampling pulse synchronization, data acquisition and processing, and the data is sent to the process layer device via Ethernet equipment and process layer in accordance with IEC61850-9-2 stan-dard framing. Using MMS Ethereal software to test voltage and current signals of output from the merging unit, the results show that the combination unit to send data and receive data consistency meeting the standard 9-2. This device can achieve the demand of merge cells of multi-tasking, a large amount of information and re-al-time high-speed communication, and have a strong practical value.
