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。
With the gradual maturity of digital substation technology, substation protection equipment features and combinations have a lot of changes and imagination. In this paper, an implementation scheme of system protection device based on the unified data source of digital substation and data sharing is proposed. The hardware design, software functions and project adaptability and reliability are discussed and analyzed. System protection is the organic integration of many decentralized protection and monitoring functions in digital substations, thus optimizing and simplifying the system data flow. System protection with low cost, easy to maintain, high performance, high reliability and other characteristics, to adapt to the future development of power system automation and market demand.
