电子式互感器合并单元(MU)的研究与设计

合并单元是电子式互感器与二次保护控制设备接口的重要组成部分。简要介绍了电子式互感器合并单元的基本定义及相关国际标准,同时对合并单元的主要功能和实现方法进行了研究,提出了一种基于现场可编程门阵列(FPGA)和数字信号处理(DSP)技术的合并单元实现方案。方案将合并单元分成3个功能模块,并对每个模块所需实现的功能进行了详细阐述和具体分析。试验结果证明该方案能够很好地解决合并单元同时处理任务多、通信信息流量大及通信速度快等一系列问题,具有较高的可靠性和较强的实时性。

Research and design electronic transducer merging unit

MU(Merging Unit)is the important component of the interface between electronic trans-ducer and protective device.The definition of MU and its international standards are introduced,and the main functions of MU and its implementation are researched.A scheme using FPGA and DSP is proposed.It divides MU into three different functional modules,which are analyzed in detail.The test results prove that MU can deal with several tasks in parallel with large information flow and high communication speed.It proves the reliability and real-time performance of MU.
