Abstract: Papers around the power quality of 10 kv work research. First, this paper introduces the main indicators of power quality and the research status at home and abroad, and then understand the for power quality research at home and abroad, at home and abroad is introduced to take the main solution for power quality problem, based on this, then put forward in this paper, we study the main content; This paper introduces the basic concept about the power quality, puts forward the main content of the study of the problem of power quality, analyzes the main factors influencing the work power quality, and the impact of these factors will bring power grid. Summarizes the power quality monitoring methods and standards. Summarizes monly used method of power quality analysis. The last in a series of theoretical knowledge in front of under ground is put forward to improve + 10 kv work power quality of the main strategies and measures.
This paper introduces the major indexes of the power quality, the status of research both at home and abroad; Understanding for power quality drop measures taken at home and abroad; Put forward the main problems existing in power quality; To analyze the main factors influencing the power quality and will be what kind of influence on power quality; Improve + 10 kv work p
