集中式保护系统以其低成本、维护简便以及信息和功能的合理优化整合等优点,正日益引起各电力公司的重视。研究了基于智能变电站的集中式保护系统,对其构成、功能特点和可靠性进行了分析,并以220 kV集中式保护为例,分析了其冗余配置方案,最后从硬件和软件方面介绍了处于系统核心的集中式保护装置。通过研究表明,集中式保护系统在技术上已日趋成熟,完全能满足智能变电站的需求,是智能变电站未来的发展方向之一。
Centralized protection systems are increasingly attracting the attention of power companies for their low cost, ease of maintenance, and reasonable optimization and integration of information and functions. The centralized protection system based on intelligent substation is studied and its composition, function characteristics and reliability are analyzed. Taking 220 kV centralized protection as an example, the redundant configuration scheme is analyzed. At last, the hardware and software are introduced At the heart of the system is a centralized protection device. The research shows that the centralized protection system has matured technically and can completely meet the demand of intelligent substation, which is one of the future development directions of intelligent substation.
