Abstract

Legacy substation automation protocols and architectures typically provided basic functionality for power system automation and were designed to accommodate the technical limitations of the networking technology available for implementation. There has recently been a vast improvement in networking technology that has changed dramatically what is now feasible for power system automation in the substation. Technologies such as switched Ethernet, TCP/IP, high-speed wide area networks, and high-performance low-cost computers are providing capabilities that could barely be imagined when most legacy substation automation protocols were designed. In order to take advantage of modern technology to deliver additional new benefits to users of substation automation, the International Electrotechnical Commission (IEC) has developed and released a new global standard for substation automation: IEC 61850. The paper provides a basic technical overview of IEC 61850 and discusses the benefits of each major aspect of the standard. The concept of a virtual model comprising both physical and logical device models that includes a set of standardized communications services are described along with explanations of how these standardized models, object naming conventions, and communication services bring significant benefits to the substation automation user. New services to support self-describing devices and object-orient peer-to-peer data exchange are explained with an emphasis on how these services can be applied to reduce costs for substation automation. The substation configuration language (SCL) of IEC 61850 is presented with information on how the standardization of substation configuration will impact the future of substation automation. The paper concludes with a brief introduction to the UCA International Users Group as a forum where users and suppliers cooperate in improving substation automation with testing, education, and demonstrations of IEC 61850 and other IEC standards technology

IEC 61850概述及其好处

传统变电站自动化协议和体系结构通常为电力系统自动化提供基本功能，并且旨在适应可用于实现的网络技术的技术限制。最近，网络技术取得了巨大的进步，极大地改变了变电站电力系统自动化的可行性。交换以太网、TCP/IP、高速广域网和高性能低成本计算机等技术正在提供大多数传统变电站自动化协议设计时几乎无法想象的功能。为了利用现代技术为变电站自动化用户提供额外的新好处，国际电工委员会(IEC)制定并发布了变电站自动化的新全球标准:IEC 61850。本文提供了IEC 61850的基本技术概述，并讨论了该标准的每个主要方面的好处。本文描述了虚拟模型的概念，包括物理和逻辑设备模型，其中包括一组标准化通信服务，并解释了这些标准化模型、对象命名约定和通信服务如何为变电站自动化用户带来重大好处。介绍了支持自描述设备和面向对象点对点数据交换的新服务，重点介绍了如何应用这些服务来降低变电站自动化的成本。IEC 61850的变电站配置语言(SCL)提供了变电站配置标准化将如何影响变电站自动化未来的信息。本文最后简要介绍了UCA国际用户组，这是一个用户和供应商通过测试、教育和演示IEC 61850和其他IEC标准技术来合作提高变电站自动化的论坛
