Abstract: The misdirected back of sampling receiving soft jumps will cause the alarm or mistaken action of the protection device.In allusion to the situation of current SV soft jumps misdirected back, the training room in intelligent substation was used to carry out experiments. Combining with the recording data of the experiments, this paper analyzed the action situation of busbar protection device when the interval sampling receiving soft jumps quitted and compared the differences between the old and the new six-unified devices, which is helpful for operators to master the functions of sampling receiving soft jumps in bus protection device, so as to standardize the operation procedure of sampling receiving soft jumps.
Key words: smart substation; sampling; soft jumps; busbar protection; misdirected back
