SYSTEM AND METHOD FOR DETECTING AN ABNORMAL WAVEFORM IN A POWER DISTRIBUTION SYSTEM

摘要

The present invention relates to a system and method for detecting an abnormal waveform in a power distribution system that changes a data transmission protocol according to data size and causes abnormal waveform-related data of a large size to be transmitted quickly. The system for detecting an abnormal power quality waveform in a power distribution system comprises: a plurality of RTUs dispersed and installed in the power distribution system, receiving a waveform measuring signal for abnormal waveform measurement, measuring an abnormal waveform, and transmitting an abnormal waveform using a protocol set according to the size of the abnormal waveform; an FEP for transmitting the waveform measuring signal to an RTU installed in a failure section from among the plurality of RTUs, and receiving the abnormal waveform from the RTU and storing the received abnormal wave; and a main server for transmitting the waveform measuring signal through the FEP to the RTU installed in the failure section, performing controlling to measure the abnormal waveform generated in the failure section in the power distribution system, and receiving and displaying the abnormal waveform according to the waveform measuring signal.
