智能变电站二次系统检修安全策略研究

Research on the Security Strategies of the Protection System Maintenance in Smart Substation

摘要: 通过对传统变电站和智能变电站体系结构的对比，研究了智能变电站二次系统检修安全策略，提出了智能变电站通用二次安全措施，并进行了分析。文章提出二次安全措施应按照适当、足够的原则，并需采用双重安全措施。在本文中作者设计了智能变电站的典型二次安全措施票，该措施票可应用于220 kV智能变电站的现场检修工作，可对二次系统检修工作的安全进行有效的保障。

Abstract: By comparing the differences of the architecture of traditional substation and smart substation, the article studies the security strategies on the protection system maintenance in smart substation. The general safety measures of the smart substation are presented and analyzed. Some safe measures should be in accordance with the appropriate and sufficient principles, and safe measures should be doubled as well. Based on the analytical results, the author designs the typical safe measures of the smart substation which can be used in the working field of 220kV smart substation, in order to provide effective protection and working security in 220kV smart substation.
