继电保护硬压板状态智能监测技术研究及应用OA

The correct activation and deactivation of hard pressure plates in relay protection devices is a crucial aspect of ensuring the safe and stable operation of the power grid.Addressing the issues of low effi-ciency,error-prone manual inspection,and inability to monitor in real-time associated with traditional manual inspection methods,a systematic solution for online monitoring of hard pressure plates has been proposed based on the technical plan of State Grid Jibei Electric Power Company.The research focuses on the acquisition principles,system architecture,and implementation strategies of two technical routes:"dual pressure plate"and"magnetic induction".A hierarchical system architecture of"acquisition-aggre-gation-station control-master station"has been constructed.The technical solution is elaborated,which in-volves unified modeling of hard pressure plate status information based on the DL/T 860 standard and up-loading it to the new generation of centralized control system and relay protection information master sta-tion through multiple paths.Application practice has proven that this solution can achieve real-time per-ception and remote monitoring of hard pressure plate status,significantly improving inspection efficiency.It provides a solid data foundation for applications such as error prevention in secondary equipment opera-tion and remote intelligent inspection,significantly enhancing the level of intelligent operation and mainte-nance of substations.
