Abstract :
On the basis of in-depth study of the relaying protections´ free distribution characteristics in digital substation, a solution to cope with the transitional situation is proposed against the background of little technology maturation in primary apparatus and the communication on process level. A design method of relaying protection software based on VxWorks is provided, and the execution path, interrelations and communication mode between the tasks is elaborated.
