PMU COMTRADE Method for monitoring and analyzing electrical power system using PMU data and COMTRADE type data

摘要

The present invention provides a method for monitoring and analyzing system accidents using PMU data and data in a COMTRADE format which can efficiently monitor and analyze accurate accident situations. The method for monitoring and analyzing system accidents comprises: (a) a step of using a data collection device to collect measurement data from a three-phase power system; (b) a step of using a computing module capable of data operations to calculate state data representing a state of the system from the measurement data, and monitoring the state data and the measurement data; (c) a step of performing operations for determining a change state of at least one among the measurement data and the state data by the computing module to detect an abnormal change; (d) a step of operating a recorder device by an operating signal when the abnormal change is detected to generate accident record data in which a change situation of the measurement data and the state data is recorded; (e) a step of displaying the accident record data in real time by a display device; and (f) a step of using an analysis program for analyzing the accident record data to read an accident state of the system from the accident record data.
