| Abstract: | Under energized condition of 220 kV bus,the process of retrofitting its bus protection into duplex configuration in 500 kV Xiaogan substation was introduced.After the retrofit,the 220 kV bus of Xiaogan substation has two sets of protection,and each set can be out of service by turns for periodic maintenance;thus the hidden trouble of safety in power grid operation is removed. |
