供电远动系统时钟对时问题的影响及优化方案

随着高速铁路的不断发展,铁路供电系统稳定运行和快速应急处置的需求越来越强烈,同时也对供电远动系统运行分析水平的要求越来越高。各类告警、报文的准确性是进行快速故障判断和故障分析的基础。本文介绍了日常运行过程中供电系统时钟同步的作用及工作方式,分析了被控站时钟发生异常对调度主站产生的影响,并提出了相应优化方案。

With the continuous development of high-speed railways,the demand for stable operation and rapid emergency rescue of railway power supply system is becoming increasingly urgent,and at the same time,the requirements for the operational analysis level of power supply remote control system are also becoming higher and higher.The accuracy of various alarms and messages is the foundation for rapid fault diagnosis and analysis.The paper introduces the role and working mode of clock synchronization in the power supply system during daily operation,analyzes the impact of clock abnormalities in the controlled station on the dispatching master station,and proposes corresponding optimization plans.
