Studies On Line Loss Of Distribution Networks And Measures For Reducing Line Loss In Liwan District Of Guangzhou

The line loss rate in the electricity production is an important technical and economic indicators, is also a measure of an important symbol of power enterprises technical level and management level. The distribution network is a direct service to customers, distribution network loss reduction and power quality improvement of great significance to improve the social benefits of electric power enterprises. Therefore, how to effectively reduce the regional distribution network line loss per unit has become a research focus both at home and abroad.This article embarks from the reality, through the investigation and analysis of the Liwan district distribution network present situation, the existence question, in the research distribution network loss calculation principle, advantages and disadvantages to all kinds of calculation method of analysis and comparison, this paper introduces the present situation of the liwan district bureau line loss, in this paper, the theoretical line loss calculation method and line loss based on the analysis of the causes, combined with the actual distribution network DaTanSha island for line loss cause analysis and research, and put forward the measures to reduce the feasibility of line loss target scheme.Based on the analysis of the line loss causes technology, in distribution network operation, construction and reactive power compensation, it puts forward corresponding technical measures, and the reactive power compensation measures after the implementation of the benefit are analyzed. The key to management line loss are discussed. To realize the standardization of the line loss management, regular line loss analysis, according to the different situation we must adopt the corresponding reduction measures. At the same time, according to the actual situation of the liwan district, the loss reduction measures to effect validation, economic benefit and social benefit analysis.Combining with the field situation, proposed the practical optimal economic plan, the existing distribution network loss reduction work has a certain guiding role. In order to realize the Liwan district of Guangzhou"technical line loss is reasonable, management line loss minimum" line loss management objectives, to minimize the line loss. The research results show that the result of this paper has stronger practicability, the distribution network loss reduction efficiency have practical function.
