摘要
本文介绍了某水电站240MW机组励磁系统进口设备国产化改造方案及其特点。新设计的励磁系统采用背靠背的盘柜布局方式,综合风冷、水冷方式实现励磁系统冷却,并以柔性电制动方式实现电气制动,实现了预期的改造效果。
This paper introduces the retrofit programs of excitation system for a 240MW hydrogenerator. Excitation system uses newly designed cabinets with back to back layout, integrated air-cooled, water-cooled cooling, and flexible electrical braking. The results achieved expected retrofitting effect.
