Analysis Of Line Loss In Distribution Network And Research On Loss Reduction Measures

The invention of electric power originated in the 1970 s of the 19 th century.The appearance of electric power has directly caused the second world industrialization tide,which has brought people into the age of electrification,electricity is already an integral part of our lives.Through the efforts of recent years,China's power grid has basically covered the country,the realization of the power for all.As for power energy,it is usually generated by power plants,and then it enters the consumer end through several links such as transmission,transformation,distribution,etc.In these links,it is inevitable that there will be power loss,for the power loss in the power transmission link,the loss of the transformer occupies a relatively large part.Nowadays,with the development of science and technology and the improvement of the consciousness of energy saving and emission reduction,people pay more and more attention to how to reduce the loss of electric energy in the process of transmitting electric energy to users.In this paper,how to minimize the transformer loss in the distribution link is studied.The main contents are as follows:(1)the definition of line loss in distribution network is introduced,the working principle of transformer used in power distribution is introduced,and the equivalent model of transformer is established,which lays a foundation for loss analysis and loss reduction measures.(2)based on the model of transformer,the calculation method of distribution transformer loss and the classification of transformer loss are expounded,the loss of transformer in power distribution link and the cause of loss are analyzed.(3)based on the model of transformer and the analysis of the loss cause of distribution transformer,this paper has made the corresponding loss reduction measures.According to the actual situation of the Zaozhuang Power Grid,the loss reduction measures proposed in this paper are verified.The results show that the loss reduction measures proposed in this paper can effectively reduce the loss caused by transformers in the distribution network,it has a good guiding significance for the planning and implementation of distribution network.(4)In this paper,a line loss monitoring platform for distribution network is designed based on the existing technology.The platform adopts the layered monitoring method to monitor the line loss in the system in real time and accurately,it is of great significance to improve the efficiency of line loss monitoring.At the same time,the data of line loss can be collected in real time by the system,which can provide up-to-date data for line loss analysis.
