摘　　要：为实现中压母线的快速保护,根据现场变电站运行参数,用RTDS仿真试验系统连接开发的中压母线快速弧光保护装置,构建了中压母线电弧光保护实时闭环系统模型。通过设置不同类型的故障点模拟中压母线的各类故障,录波并分析保护的动作行为,研究弧光保护作为中压母线快速保护的可行性,并验证了其满足保护选择性与灵敏性的设计初衷。In order to realize the fast protection of MV （medium voltage） busbar, RTDS simulation test system is connected to the developed arc-flash protection device of MV busbar in accordance with operating parame- ters of field substation to establish the real-time closed-loop system for arc-flash protection of MV busbar. By setting different types of fault locations, various faults of MV busbar are simulated. The waves are recorded and action behavior of the protection is analyzed. The feasibility of arc-flash protection as fast protection of MV busbar is investigated, and the original intention of the design to meet the protection selectivity and sen- sitivity is verified.
