变电站自动化系统设计中的几个问题

On substation automation system design

就变电站无人值班改造应采用自动化系统还是常规二次设备加远动装置,以及变电站自动化系统是采用集中式结构还是采用分层分布式结构进行了分析,提出了在现阶段应采用自动化系统;对已运行的变电站其自动化系统宜采用集中式结构,除非10kV设备一并换型才考虑采用分层分布式结构;新建变电站应根据电气一次设备的选型及布置决定自动化系统的结构型式。

Whether the automation system or the conventional secondary equipment supplemented with telecontrol devices should be employed in the reconstruction of the unmanned substations, and whether the centralized configuration or the hierarchic and distributed configuration should be adopted for the substation automation systems are analyzed. The followings are suggested. At present, the automation systems should be employed. For the operating substations, the centralized configuration should be adopted, and the hierarchic and distributed configuration could be considered only when the retrofit of the 10 kV equipment is executed in the meantime. For the new substations, the automation system structure will depend upon the types and layouts of the electric primary equipment.
