摘　　要：针对现有继电保护实验装置均不能对合并单元输出信号的分配、传输环节进行完整检验的缺陷,设计了一种新型基于高级RISC微处理器(advanced RISC machines,ARM)和现场可编程门阵列(field-programmable gate array,FPGA)协同工作的智能变电站全场景试验装置硬件平台。结合软件仿真平台,该套系统可以实现模拟实际智能变电站内电子式互感器→采集单元→合并单元的数据传输全过程,将实验室进行的试验带到现场,从而方便、快捷、安全地模拟线路中各种故障,为智能变电站二次继电保护试验提供一种新型的试验装置。实验结果表明,硬件平台能正确发送数据并且同步精度达到20μs。Aiming at the defects of relay protection testing apparatus that the distribution and transmission of output signal of merging unit can not be inspected thoroughly,a new hardware platform of whole-scene testing apparatus based on advanced RISC machines（ARM） and field-programmable gate array（FPGA） is designed.With the software platform,the hardware platform can realize the whole process of data transmission from electronic instrument transformer to acquisition unit,and to merging unit in the real smart substation,which can bring the laboratory tests to the field so that the different faults can be simulated conveniently,fast and safely.It provides a testing apparatus for relay protection in secondary sides of smart substation.The test results show that the data can be transmitted correctly by the hardware platform and the synchronization accuracy is 20 μs.
