摘要

光电互感器具有结构简单、抗干扰能力强、响应迅速等优点

使其在高压直流系统（HVDC）中得到了广泛的应用。笔者分别介绍了基于罗戈夫斯基线圈、精密电阻的光电电流互感器（OCT）和基于阻容分压元件的光电电压互感器（OVT）的结构组成、测量系统的工作原理以及其在高压换流站中的应用情况

并结合光电传感器及其测量系统在实际工程的典型故障案例

分析了故障产生的原因及对高压直流控制保护系统的影响

为光电互感器的运行及其在后续工程中的改进提供一定的借鉴。

Abstract

Optical transducer has been widely used in HVDC system

due to the advantages of simple structure

strong anti-interference ability

rapid response and so on.In this paper

the structure and measurement system of the optical current transducer based on Rogowski coil

precision resistance and the optical voltage transducer based on resistive-capacitive divider have been introduced

also the application situation in HVDC converter station

the reason of the fault and the affect on the HVDC control and protection system are analyzed in typical faults from the practical engineering

which can provide some reference for optical transducer operation and improvement in subsequent engineering.
