Title:
ELECTRIC POWER QUALITY MONITORING SYSTEM AND ELECTRIC POWER QUALITY MEASURING METHOD
Document Type and Number:
WIPO Patent Application WO/2011/040663
Kind Code:
A1
Abstract:
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.
