| 摘 要： | 分析了智能变电站对传统计量系统的影响,针对计量系统的计量精度要求、高采样率要求及对计量装置的检定要求给出了解决方案。根据智能变电站内计量系统的设置原则及其功能,提出了站内计量系统的3种设计方案;对不同方案特点的分析,对各方案的适用性及其组屏方式给出建议;对于现阶段枢纽智能变电站推荐采用方案二,即智能电表通过站控层MMS(Manufacturing Message Specification)网向电能量远方终端传输电量信息;在投资较小的终端变电站可采用方案一,即智能电表与电能量远方终端单独组网;待智能变电站相关检测标准、溯源规程制订完善并获得认可后,可采用方案三,即采用计量插件。
