基于云服务的保护实验台中保护装置逻辑策略的动态模拟实现

Dynamic Simulation Implementation of Protection Device Logic Strategy in Shared Experimental Platform Based on Cloud Services

传统的基于物理接线的电力自动化及继电保护试验台已经在各大院校推广使用,传统的试验台是作为电力专业课程教学实验项目开展的工具,侧重于理论验证、实验开展、保护校核等内容,对于学生的学习有很大帮助。本设计是面向现场工程运维人员,从系统设计及应用角度考虑,基于Web实现保护装置的内部原理及外部回路的仿真模拟,通过逻辑策略的可视化,实现保护内部信息流及数据流的展示,达到原理透视的效果,从而指导变电站内运维人员更有针对性地进行故障排查和消缺。

The traditional power automation and relay protection test bench based on physical wiring has been promoted and used in various universities.The traditional test bench is a tool used as a teaching experiment project for power professional courses,focusing on theoretical verification,experiment development,protection verification and other content,which is very useful for students'learning.The design is aimed at on-site engineering operation and maintenance personnel.From the perspective of system design and application,the internal principle and external circuit simulation of the protection device are implemented based on Web.Through the visualization of logical strategies,the internal information and data flow of the protection are displayed,achieving a principle perspective effect,guiding the operation and maintenance personnel in the substation to conduct more targeted fault diagnosis and elimination.
