| Abstract: |
| This paper introduces the implementation scheme of outdoor installation bus protection from three aspects:sub-machine configuration scheme, ring network communication scheme and protection special network communication scheme. It firstly analyzes the problems which outdoor installation busbar protection may meet in the implementation, such as operation behavior disagreement, heavy workload in process configuration, low disconnector reliability, etc., and then proposes the corresponding solutions. Finally, the functions of outdoor installation busbar protection which can be optimized and improved are introduced. Compared with the traditional busbar protection, out-door installation busbar protection improves the bay access ability, the reliability of the data communication, and the protection operation speed, which has more technical advantages and broad application prospects.
