Considering effects of the auto-switch-on device on the power quality improvement this paper examines the ope-rating conditions and action requirements of the auto-switch-on device. For a 110 kV substation connected with distributed power,the paper studies fluctuations of the system voltage and frequency when the main supply power is tripped. Based on applications of the transmission line auto-switch-on device,bus auto-switch-on device and regional power grid of auto-switch-on device in the Guangdong Power Grid,the paper explains the principles of restoring the substation power supply of the various types of auto-switch-on devices. And to improve the reliability of the auto-switch-on device,the paper proposes measures to be taken for strengthening the management and associated discon-nection of distributed power. Implementation of these measures helps to reduce the impact of distributed power on the auto-switch-on device,shorten the time of the auto-switch-on device and improve the regional power supply reliability and lessen the load loss of the substation.
