Programmed operation is a new kind of switching operation mode in substation

which can greatly improve the efficiency of switching operation and reduce fast restoration time.This paper focuses on the programmed operation of 12 kV central withdrawlable metal-enclosed switchgear to analyze the principles and characteristics of the operation.In view of practical application to Guangdong Power Grid

this paper also analyzes the applications of the programmed operation in modern intelligent substations by considering the programmed operation’s procedure

realization principle and characteristics

and the current application status in Guangdong Power Grid.Some solutions to the problems existing in the programmed operation procedure are offered according to the practical situation

such as increasing motor and changing underpan

to promote the programmed operation procedure for modern intelligent substation.
