摘要
由于运行年份较长,500 kV变电站面临二次设备整体老化等问题,常规变电站二次设备的智能化改造势在必行。以金华500 kV双龙变分阶段停电智能化改造为例,详细介绍了采用过渡接口装置解决智能化改造过程中的母差保护改造难点问题,为变电站二次设备智能化改造提供了典型经验和成功案例。
With the ageing of the entire secondary equipment in 500 kV substation that runs long for a long time, intelligent transformation of secondary equipment in traditional substation must be conducted. Taking phased intelligent transformation with power cut of 500 kV Shuanglong substation in Jinhua as an example, the paper introduces treatment of difficulties in bus differential protection transformation through transition in-terface device,providingtypicalexperienceandsuccessfulcaseforintelligenttransformationofsecondarye_ quipment in substations.
