| Abstract: |
| Combined with the 220 kV automatic bus transfer projects of Jiangsu power system,the typical system wiring mode and simplified system wiring mode are introduced,as well as the operation patterns of automatic bus transfer device in simplified mode. The schemes of fault isolation and supply recovery are discussed. The countermeasures and adaptabilities of automatic bus transfer device during system operation pattern change are described,and its software functions in 220 kV terminal substation are detailed. The research will improve the reliability and quality of power supply. |
