    • PURPOSE: A power quality data acquisition system and a method thereof are provided to collect the power quality data of an electric power system from an acquisition server, compute the collected power quality data into a predetermined time unit and transmit to a main server, thereby preventing an abnormal situation such as the load or malfunction which is able to occur as the amount of the power quality data increases. CONSTITUTION: Using a socket communication, an acquisition server(110) applies the predetermined information set by a user through a user terminal(30) to a PQM(10)(S311). The acquisition server collects the power quality data once in a second from the PQM(S312), performs the data computation work with the collected power quality data in the predetermined time unit and produces a power quality data aggregate. The acquisition server transmits the generated power quality data aggregate to a main server(120) and stores in a database(125) of the main server(S321). The acquisition server receives the predetermined information stored in the database of the main server, compares with the predetermined information in which a user have set again, and updates the predetermined information according to a comparison result(S322). The acquisition server transmits the real-time power quality data which the user requested through the user terminal to the user terminal(S331). By using the socket communication, the user terminal transmits the predetermined information which the user inputted to the acquisition server(S332). The database of the main server transmits the past measurement data which the user requested through the user terminal to the user terminal(S341). Using the user information stored in the database of the main server, the user terminal controls an access of the user, and when the user wants to change the user information the terminal receives the changed user information and restores in the database of the main server(S342).
