<p>PROBLEM TO BE SOLVED: To provide an automation system of power distribution and a monitoring method thereof, capable of collecting synchronized measured data from a plurality of slave stations, even in normal communication lines. SOLUTION: This automation system of power distribution collects monitoring data from the plurality of slave stations 5 via a network 7 and monitors a distribution line 3, where a monitoring and controlling terminal 8, which generates data storage command 11 to store higher harmonics measured data to all of the slave stations 5 at the same time (t1), in the event of a instantaneous ground short-circuit accident, and all of the slave stations 5 store the measured data by making measurements. Subsequently, the monitor and control terminal 8 sends stored data sending back commands 12, 14, 16, to send the stored measured data back thereto sequentially (t2, t3, t4) to the respective slave stations 5, and the respective slave stations 5 send the stored measured data back thereto sequentially (t2', t3', t4'). Thus, the monitor and control terminal 8 acquires highly synchronized (t1) measured data.</p> |
