The data alignment method comprises: obtaining first sampled current data from a first sampling device; receiving a second message from a second differential protector, the second message comprising second sampled current data and its sampling time stamp, first time information of the second differential protector related to a difference in time of reception from receipt of the first message to a second time node, and second time information of the second differential protector related to a second transmission processing delay from the second time node to transmission of the second message; when time synchronization is maintained, calculating and storing a time calculation deviation between a third time node and a first calculated value of the second time node; when time synchronization is lost, determining the third time node according to the stored time calculation deviation.",
