Power Quality Problems Caused by Supraharmonics and Related Research
With more and more power electronic appliances and power line carrier communication technology are applied in power systems, which on the one hand have brought about many benefits, but on the other hand have generated more and more supraharmonics emission into the gird, and thus have led to many new power quality problems. In this paper, the interference to lighting equipment, power meters, power line communication(PLC) and other electrical equipment is reviewed, such as electrical equipment unintentional switching off and on, power line communication interrupted, the power meter accuracy declining and filter burned, etc., the generation mechanism, propagation characteristics, equivalent circuit and simulation models, measurement methods and standardization of supraharmonics are summarized. Based on the research results, we notice that the power quality caused by supraharmonics has not been given sufficient attention, and related research is still in its initial stage. However, power electronics and intelligent control of the grid is the development trend, and the breakdown and mal-functioning of the electrical equipment caused by supraharmonics will be more seriously than ever. The aim of this paper is to call for scientists at home and abroad to work together, to cope with this challenge and to find solutions to the new power quality issue caused by supraharmonics.
