Discussion of application about using of big data technology in harmonic monitoring platform

Abstract

At present, several provinces' power supply companies have established harmonic monitoring platform in China, by real-time monitoring the voltage and current of power grid, then upload these data to the main station to analyze and settle. The platform can collect about 1 TB(1TB=1000GB) data every day[12], these data contain all the indexes of power quality, but we can only use this platform to do some basal data analysis work, but not processing analysis with multi-indexes, so that it does not show strong supporting effort to the power grid operation. With the development of energy internet and the third industry, more and more unstructured data are impacting the power grid operation, how to make better use of big data technology to deal with the data from monitoring platform has became the focus of the power grid company. In this paper, some introduces of contents and characteristics of harmonic real-time monitoring platform and big data technology has been made, by comparing the way of using and settling data of platform to the big data technology, meanwhile by combining with the characteristics of power quality data, we analyze the combination of the two prospects. At last, the development direction of the advanced application for the harmonic line monitoring system is discussed in this paper.
