数字化变电站自动化技术的应用分析

Application Analysis of Digital Substation Automation Technology

变电站作为改变电压的电力基础设施,在满足社会各领域电力能源需求方面起到不可替代的重要作用。近年来,随着智能化、数字化技术的迅猛发展,在基于IEC61850全球通用标准的前提下,由电子式互感器、智能化开关与网络化二次设备分层构建的数字化变电站模式应运而生。由于这种现代化变电站经济性好、安全性高,逐步替代了以电磁型互感器为主导的传统变电站。基于此,文章将着重围绕数字化变电站系统结构,以及自动化技术在数字化变电站的具体应用予以全面阐述。

As the power infrastructure of changing voltage,substation plays an irreplaceable role in meeting the power energy demand in various fields of society.In recent years,with the rapid development of intelligent and digital technology,under the premise of IEC61850 global standard,the digital substation mode,which is composed of electronic transformer,intelligent switch and network secondary equipment,emerges as the times require.Because of its good economy and high security,the modern substation has gradually replaced the traditional substation dominated by electromagnetic transformer.Based on this,this paper will focus on the digital substation system structure,as well as the specific application of automation technology in digital substation.
