港口变电所综合自动化系统抗电磁干扰的措施

Improvement of an Ability to Resist Electromagnetism Disturbing in Automation System in Electric Power Substation in Port

介绍了港口变电所系统电磁干扰的来源、传输途径和信号模式,阐述了通过消除或抑制干扰源、传播途径和电磁敏感设备来提高变电所综合自动化系统抗电磁干扰能力的方法。

This paper analyzes the cause of system electromagnetism disturbing in electric power substation in port, the system transmission track and the signal＇s mode. Then, the paper introduces the way to eliminate or restrain the disturbing cause, the transmission track or electromagnetism sensitive appliance in order to enhance the ability to resist the electromagnetism disturbing in the automation system in the electric power substation.
