SYSTEM AND METHOD FOR MONITORING POWER FACILITY STATUS BY MEASURING ONLINE ELECTRIC CIRCUIT PARAMETER

摘要

The present invention relates to a system and a method for monitoring a power facility by measuring from online a line parameter of the power facility that is in operation, and the system for monitoring the power facility, according to the present invention, sets a measurement time and selects a facility to be measured in accordance with external input, receives current and voltage data which are measured from the facility to be measured, extracts the current and voltage data that are simultaneously measured at the measurement time that is set, by referencing time information that is tagged on the current and voltage data that are inputted, removes zero-phase-sequence component from the current and voltage data, outputs the line parameter with respect to the facility to be measured that is selected by using the current and voltage data from which the zero-phase-sequence component is removed, determines the electrical status of the facility including malfunction and various connection statuses depending on whether the size or the increase/decrease rate of the line parameter that is outputted is beyond a predetermined standard value to output a status notification message or a trip signal, thereby monitoring/controlling the status of the facility to be measured.
