Aiming at the problem of standby power auto switch device not meeting the demand about three incoming power supply in the process of installation at 110 kV Yanchi Substation,by improving software logic,transforms the PSP641U standby power auto switch device of State Power Nanjing Automation Company into 110 kV special standby power auto switch device. The application result shows that the improved software logic satisfying the operation need of 110 kV substation under different operation mode,can accurately put into standby power source when the bus lose voltage,effectively improves the reliability of power supply for Yanchi Substation.
