A method for self-recovery of abnormal calendar clock of electric energy meter concentrator includes the following steps: 1) setting a timer W by concentrator; 2) the concentrator selects one electricenergy meter from the measurement point file and checks the read-back electric energy meter calendar clock format; 3) calculates a temporary valid time currently obtained from that electric energy met; 4) the concentrator generates a timing interrupt every second during this period; 5) repeats steps 2), 3), 4) until three or five temporary valid time are read; 6) sorting the temporary timing values of the three or five tables read out, and selecting one of the times as the final calendar clock recovered by the concentrator according to the principle of taking the median value. The invention adopts the calendar clock mechanism of reading the electric energy meter to recover the clock of the concentrator itself, which can recover in time when the clock is abnormal, does not need to wait forthe master station to issue the correction instruction, and does not increase any cost.
