| Abstract: |
| The automatic bus transfer equipment is important for the safe and reliable power supply in electric power systems.Taking the automatic bus transfer equipment of Changde 110 kV power network as an example,its setting,switching mode and logic in 110 kV network are intro-duced.The operating logics and processes of the automatic transfer of the incoming line breaker and the bus-tie switch are presented.Some cautions and countermeasures during switching are pointed out.In different operating modes,the transfer does different influences on the system,which ought to be processed properly. |
