摘要
随着水电站励磁系统运行年数的增长,励磁系统中晶闸管、快熔等一次设备逐渐老化,以及水电站振动较大引起一次回路接触不良等因素导致功率柜均流系数相比设备投运初期变差。部分设备均流系数虽与投运时相比,没有太大变化,但由于国标行标要求的提高,不再满足要求。本文提出了一种基于阻容滞相脉冲电路技术来提高此类水电站励磁系统功率柜均流系数的方法。
With the increase of the operation years of the excitation system of the hydropower station, the primary equipment such as thyristor and fast fuse in the excitation system is gradually aging, and the vibration of the hydropower station is large, causing poor contact of the primary circuit, and the current sharing coefficient of the power cabinet is changed compared with the initial operation of the equipment.
