Abstract: With the progress and development of society, we are increasingly dependent on high-quality electricity, good power quality for the national economy and the development of the entire industry is essential, so the power quality research, but also foreign countries are very Attention to a study。 First, the paper analyzes the source and the harm of the power quality in detail, and makes a more intuitive understanding of the power quality indicators by studying the quality of the power quality at home and abroad。 Secondly, in order to solve the problem of power quality and to monitor, control and control the power In the study, we combine the concrete examples of the actual energy control in the production to carry out the research, and introduce the "nine zone map", "five area map", the " (APF) in the power quality controller, and the model of the active power filter is established by MATLAB software。 The principle of the active power filter (APF) in the power quality controller is introduced。 The harmonic compensation of power is simulated and tested according to the test results。 Finally, the paper summarizes the positive contribution of this paper to the development of power quality control and the development of power quality control and the future development trend。
Keywords: Power quality, power quality standard, monitoring device, control method, APF, MATLAB simulation
