智能变电站技术及其应用研究 The Research of Intelligent Substation Technology and Its Application 钱海英 2016年3月 摘 要 智能电网将各种技术在电力系统中的应用进行集成与融合,代表着现代电网建设的理念、目标,是所有电力新技术应用的总称。智能电网被公认为是解决当前电力系统在安全、环保、智能等多方面问题上最有效可靠的方案,与此同时智能变电站被当成是建设坚强智能电网的重要环节和基本要素。智能变电站作为变电环节的关键,对智能电网的建设和发展具有重要意义。 本文介绍国内外智能变电站的研究现状下,提出智能变电站的概念,具体分析了智能变电站的架构,智能变电站的功能特点,以及比较了智能变电站与常规变电站在功能上的异同; 以及智能变电站的发展过程。文中详细分析了智能变电站的相关技术,智能变电站电子互感器与常规互感器的区别及优势,智能断路器的相关技术,合并单元以及变压器监测技术。结合常规变电站的继电保护配置,深入说明智能变电站继电保护的技术原则、配置原则,其中在继电保护配置原则,详细阐述了变压器、高抗及其他重要设备的保护配置。文中详细阐述智能变电站重要高级应用功能,对智能变的信息平台架构惊醒了介绍,并对其中顺序控制、智能告警及分析决策、在线监测技术等高级应用功能的实现方式进行分析研究,以及介绍了在线动态安全评估和控制。 关键词:智能电网 应用功能 合并单元 智能控制 Abstract Smart grid will be a variety of technologies in the power system application integration and integration, represents the concept of modern power grid construction, the goal is the general term for all new technology applications. Smart grid is recognized as a solution to the current power system in safety, environmental protection, intelligence and other aspects the effective and reliable. At the same time intelligent substation is referred to as an important part of building a strong smart grid and the basic elements. Intelligent substation is the key of the substation, which is of great significance to the construction and development of smart grid. In this paper the current research status of Smart Substation at home and abroad, puts forward the concept of smart substation, detailed analysis of the substations intelligent architecture and features of intelligent substation and the similarities and differences compared the intelligent substation and traditional substation in function, and intelligent variable power development process. In this paper, the technology of Smart Substation is analyzed in detail, the difference and advantages of the electronic transformer and the conventional transformer, the technology of the intelligent circuit breaker, the merging unit and the transformer monitoring technology are analyzed in detail.
