ELECTRIC POWER QUALITY MONITORING SYSTEM AND ELECTRIC POWER QUALITY MEASURING METHOD

摘要

Disclosed are an electric power quality monitoring system and an electric power quality measuring method. An apparatus for measuring the quality of an electric power system comprises: a pickup unit for acquiring voltage and current waveforms of an electric power system at set time intervals; a sampling unit for sampling and storing the acquired voltage and current waveforms over a set period, for harmonic component analysis; a waveform generator for overlapping and combining voltage and current waveforms sampled over the set sampling period into one cycle, and generating a representative waveform; and a transmitting unit for transmitting the representative waveform via a communication network to a monitoring server.
