摘要
根据IEC61850标准对合并单元的定义,从分析合并单元的功能和结构入手,研究了合并单元的设计与实现,描述了主要模块的电路结构,特别说明了合并单元的同步需要考虑问题。结合实际设计开发经验,总结了合并单元设计中应注意的问题。最后简要介绍了合并单元与二次设备的连接方式、数据通信方式、以及合并单元在数字化变电站中的配置模式。
Based upon the definitions of Merging Unit(MU) in IEC 61850 standards, beginning from the analysis of the functions and structures of the Merging Units, it is studied on how to design and realize a general MU. Its electronic circuits structure is described, especially for the synchronization considerations. Combined with development practice the details in which more attentions should be paid are presented. At the end the connection modes between MUs and secondary devices, data communications, and its configuration examples are briefly introduced.
