基于数字化变电站的系统保护装置设计

随着数字化变电站技术的逐渐成熟,变电站保护设备的功能及组合方式有了很大的变化和想象空间.文中提出一种基于数字化变电站数据源统一、数据共享特点的系统保护装置的实现方案,并对其硬件设计、软件功能实现以及工程适应性、可靠性进行了探讨和分析.系统保护是对数字化变电站内诸多分散的保护测控功能模块的有机集成,从而优化并简化了系统的数据流.系统保护具有低成本、易维护、高性能、高可靠等特点,能适应未来电力系统自动化的发展和市场需求.

Design of System Protecting Devices Based on Digital Substations

With the gradual maturity of digital substation technology,the function and combining mode of intelligent electronic devices (IEDs) may have plenty of room for changes. A schema for the realization of a system protecting device is proposed based on data sharing and unified data source in the digital substation. Also discussed are its hardware design,software functions realization,adaptability and reliability in application. As system protection is the organic integration of many decentralized monitoring and...
