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 an abnormal waveform in a power distribution system that quickly transmits abnormal waveform-related data of a large size by changing a protocol according to data size. The system for detecting an abnormal power quality waveform comprises: a plurality of RTUs for measuring abnormal waveform when a waveform measuring signal received, 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, and receiving and storing the abnormal waveform from the RTU; 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, and receiving and displaying the abnormal waveform according to the waveform measuring signal.

1. A system for detecting an abnormal power quality waveform in a distribution system, comprising:
a main server configured to, when a fault occurs in a distribution system, generate a waveform measurement signal, and receive, store, and display abnormal waveforms or voltages and currents of the distribution system measured in a fault section of the distribution system; a Front End Processor (FEP) configured to transmit the measurement signal generated by the main server to one or more Remote Terminal Units (RTUs) installed in the fault section, receive abnormal waveforms or voltages and currents of the distribution system from the one or more RTUs, and transmit the abnormal waveforms or the voltages and currents to the main server; and a plurality of RTUs, each being configured to, when the waveform measurement signal is received from the FEP, measure a voltage and a current of the distribution system, generate an abnormal waveform, convert the measured voltage and current or the abnormal waveform into data of a protocol format set based on request data included in the waveform measurement signal, and transmit resulting protocol format data.
