A Survey of Power Quality Development Based on the Method of Information Visualization
In order to dig out the research hotspots in the field of power quality knowledge at home and abroad and predict its future development trend. Using the method of information visualization and Cite Space information visualization software, this paper analyzes the related literature of power quality research in the 2007-2017year CNKI and Web of Science database and draws the knowledge atlas of the transformation knowledge map of the quotation structure at home and abroad and the co-cited knowledge map of the WOS literature and analyzes the domestic and foreign literature. The results show that the research hot spots in the field of power quality research at home and abroad are basically identical, and they all pay more attention to the problems of power quality control, such as harmonic, voltage sags and power quality disturbance recognition, but the development trend at home and abroad is slightly different.
