[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.
