首先对CIGRE SC B5保护和自动化专业委员会的研究领域、代表、工作组活动、年度会议安排等情况进行了介绍。2012年CIGRE巴黎会议B5学术研讨会的主题有2个:未来电网中的元件对保护和自动化系统配合的影响;远程访问在保护和自动化系统中的应用。柔性交直流输电设备的应用、含分布式电源的非放射式(网络化)配电网等要求采用新原理的继电保护技术,复杂电网中的继电保护、自适应继电保护需要能够自动进行校核的工具。应研究下一代智能变电站,以进一步实现数据和信息共享、二次功能的集成以及新型互感器和过程层总线的应用,同时不能牺牲系统的安全性、可靠性。随着电网拓扑结构的变化,传统稳控系统面临改造,基于离线分析的开环紧急控制将逐步发展到基于在线分析的开环紧急控制。为了降低成本、提高整体运行效益,除了数据采集与监控(SCADA)数据之外,“非实时数据”或者说“非运行数据”在厂站与主站端之间的交换将变得越来越重要,包括故障分析、资产管理和运行等方面的应用。在统一的IEC 61850标准下,远程访问的通信通道和通信协议需要统一设计,网络安全问题必须得到解决。
First CIGRE SC B5 Protection and Automation Committee of the field of study, representatives, working group activities, the annual meeting arrangements were introduced. There are two topics at the 2012 CIGRE Paris Conference B5 Symposium: The Impact of Future Components in the Grid on Protection and Automation Systems; and Remote Access in Protection and Automation Systems. Application of flexible AC and DC transmission equipment, non-radiating (networked) distribution network with distributed power, etc. Relaying protection technology requiring new principles, relay protection in complex power networks, adaptive relay protection needs to be able to automatically Tools for checking. The next generation of smart substations should be studied for further data and information sharing, integration of secondary functions, and application of new types of transformers and process-level buses without sacrificing system security or reliability. With the change of power network topology, the traditional steady-control system is undergoing transformation. The open-loop emergency control based on offline analysis will be gradually developed to open-loop emergency control based on online analysis. In order to reduce costs and increase overall operational efficiency, the exchange of “non-real-time data” or “non-operational data” between the plant site and the master site in addition to SCADA data will change Have become more and more important, including the application of failure analysis, asset management and operation. Under the unified IEC 61850 standard, the communication channels and communication protocols for remote access need to be uniformly designed, and the network security problems must be solved.
