摘要 随着国家“碳达峰、碳中和”政策的专业引领,特高压直流输电技术近年来蓬勃发展,换流站的精益运检对在运直流工程的平稳运行起着至关重要的作用。换流站监控系统作为运行人员实现换流站事件报警全面监视的有利工具,存在故障时大量报文涌出导致难以准确辨识故障原因的情况。对此,首先对换流站监控系统的通信架构进行了深入研究,在了解换流站内通信规约的结构和基本规则的基础上,研制出一种换流站通信规约解析软件,实现报文导入后的规约自动判别和解析,为现场检修人员提供一种便携的通信规约辅助分析工具,显著提高现场的故障定位和诊断效率。 With the professional guidance of the national"carbon peak and carbon neutral"policy,UHV DC transmission technology has developed vigorously in recent years,and the lean operation and inspection of converter stations plays a vital role in the smooth operation of the DC projects in operation.As a favorable tool for operators to realize comprehensive monitoring of converter station event alarms,the converter station monitoring system has many messages gushing out during faults,making it difficult to accurately identify the cause of the fault.In this regard,the communication architecture of converter station monitoring system was first studied.Based on understanding the structure and basic rules of the communication protocol in the converter station,a communication protocol analysis software of the converter station is developed to realize the automatic identification and analysis of the protocol after the message is imported.The software provides field maintenance personnel with a portable,communication protocol auxiliary analysis tool that significantly improves the efficiency of fault localization and diagnosis in the field.
