光字信息系统在500kV变电站的应用

Application of Visual Annunciator Information System in 500 kV Substation

在变电站运行中,光字信号回路图是运行人员判断光字异常的依据,由于查找光字回路图耗时耗力,判断光字的及时性得不到满足。在对现场应用需求及相关新技术进行研究的基础上,提出了1套可行的光字信息系统设计方案,通过在500 kV天柱变电站的应用表明,光字信息系统在很大程度上提高了运行人员处理现场异常情况的效率。

Visual annunciator signal circuit diagram is the basis for operators to judge abnormity of visual annunciator during the operation of substation.Since it costs much time and effort to search visual annunicator circuit diagram,the judgment of abnormal signal can not be achieved in time.This paper presents a feasible plan for design of visual annunciator information system based on the researches on the onsite application requirements and new technologies.The application in the 500 kV Tianzhu substation indicates that the visual annunciator information system improves the efficiency of operators dealing with abnormal situation to a great extent.
