摘要
随着电子式电流、电压互感器的实用化和变电站开关设备的智能化,变电站自动化系统过程层与间隔层之间大量复杂的并行电缆连接将会逐渐被串行光缆连接所代替。文中分析并比较相关的国际标准,指出合并单元是实现过程层与间隔层串行通信的重要部分,提供了实现合并单元功能的模型。
Novel electronic current and voltage transducers are now being put into practice, the switching devices of the substation are more
and more intelligent, as a result, the parallel and complicated wiring between the process level and the bay level of the substation automation
system will be replaced by serial link. Some relevant international standards are firstly analyzed and compared, it is pointed out that the
merging unit is the key to realize the serial communication between the process level and bay level, and the model that can be used to realize
the function of the merging unit is supplied.
