【摘要】 变电统自动化系统的一项重要功能是站内各种智能装置的通信,该领域技术发展的趋势是通信规约的网络化及国际标准化。随着开放性的增加,特别是采用网络化的 IEC61850标准成为发展方向时,网络的安全问题越来越突出。IEC针对变电站内主要通信规约,制定了IEC62351安全国际标准,它在通信的多个层次上进行认证或加密,极大提高了规约的安全性。该文在介绍了IEC62351标准的主要内容后,提出了为符合该标准的自动化系统应该进行改造的主要内容及重点解决的问题。更多还原

【Abstract】 In Substation Automation System (SAS), it is one of the key functions to communicate with all kinds of lEDs. The technology development tends to be network communication protocols and international standardization. With increasing openness, especially IEC 61850 involving network communications being development trends, network security will be more and more critical. Taking consideration of main power system communication protocols, the International Electrotechnical Commission (IEC) developed IEC 61351 security standards, which make great improvements in data and communication security using authentication and encryption covering different protocol layers. This paper introduces the main contents of IEC 62351 and presents modification aspects and the major problems to be solved for substation automation system based on IEC 62351.更多还原
