【摘要】：保护设备就地化的难点之一是实现母线保护等跨间隔保护设备的就地化,文中在分析现有分布式母线保护特点的基础上,提出了基于多个高可靠无缝冗余环网的分布式母线保护方案和具体的软硬件平台实现架构。文中基于FPGA技术实现了环网报文时延的准确测量及补偿,并提出了不依赖于外部时钟的基于采样事件的采样同步技术。通过采用环网拓扑监视和弱配置管理等关键技术,实现了环网通信状态的实时监视以及子机终端的少配置、弱管理应用,提高了运行维护的方便性。最后,通过对该方案主要性能参数的实际测试,验证了该方案的可行性。
[Abstract]:One of the difficulties of localizing protection equipment is to realize the localization of bus protection and other cross-spaced protection devices. Based on the analysis of the characteristics of existing distributed bus protection, This paper presents a distributed bus protection scheme based on multiple high reliability seamless redundant ring networks and a specific hardware and software platform implementation framework. In this paper, the accurate measurement and compensation of packet delay in ring network are realized based on FPGA technology, and a sampling synchronization technique based on sampling events is proposed, which is independent of external clock. By using the key technologies of ring topology monitoring and weak configuration management, the real-time monitoring of the communication state of the ring network and the less configuration of the subcomputer terminal are realized, and the application of weak management is improved, and the convenience of operation and maintenance is improved. Finally, the feasibility of the scheme is verified by testing the main performance parameters of the scheme.
