Abstract:The grid structure of the modern power system and load constitute the emergence of new trends, and brought the power quality problems gradually cause the power sector and a high degree of user attention. Power quality analysis and control strategy is to analyze and improve power quality a prerequisite for ensuring the security of the power system operation and user safe use of electricity has important theoretical and practical significance. Modern power system operation and smart grid development to a higher demand for power quality analysis and control technology. Traditional power quality analysis and control methods are no longer satisfied the need for power quality analysis and control technology has carried out research work.
Research and concepts from the power quality, this paper, summary of the various methods of analysis and control of the power quality at home and abroad through a variety of power quality phenomena, summarized the current domestic and international power quality control methods and strategies for different power quality phenomena, a different method of power quality control.
Keywords: power quality, analysis, control
