我国贵州-广东Ⅰ回、Ⅱ回±500 kV高压直流输电和西北-华中（灵宝）联网直流背靠背工程中

均采用了用激光脉冲直接触发晶闸管的直接光控晶闸管换流阀（以下简称LTT阀）。为了确保触发光脉冲的可靠性

在阀底部电子设备柜（VBE）中设置了对光发射电路进行在线实时监测的功能。笔者就近年来运行中激光发射监测出现的一些问题进行探讨。

The light triggered thyristor valves

which are directly triggered by laser

are used in Guizhou-Guangdong ±500 kV HVDC Ⅰ

Ⅱ power transmission lines and Lingbao HVDC back-to-back project.To ensure reliable laser trigger pulse

the laser emitter is monitored real-timely by valve base electronics on line.Some issues about laser emitter monitoring are discussed in this paper.
