| Abstract: |
| According to the basic principle of automatic bus transfer,a new scheme is presented,which is designed for the typical and standard inter-bridge connection of substations and is reliable and adaptive.With a certain connection mode as an example,the principle and characters of the automatic bus transfer are analyzed in detail.It integrates the functions of measuring,protec-tion,control,communication and display to automatically trace the present operating mode of substa-tion system and real-timely and reliably complete the transfer action logic.With the communication interfaces of RS-232,RS-485,CAN field bus and Ethernet,it is available for different connection modes of power system. |
