A Multicastbased Pre-acceptance Examination Method for Secondary Equipment of Smart Substation
In order to improve the efficiency of pre-acceptance examination of secondary system in smart substations,re-duce the overall station pre-acceptance examination time,and accelerate the operation of the substation,this work studied the communication structure of secondary system in smart substations and proposed a multicast-based method to pre-ac-ceptance examine secondary equipment.The proposed method can effectively exert expected utility.
