The power loss of distribution network is a key index to measure the operation efficiency and economy of distribution network.It is of great significance to improve the power utilization rate,save energy costs and promote the economic operation of distribution network by accurately calculating the power loss of distribution network and formulating effective loss reduction measures.Taking theoretical line loss calculation and statistical line loss calculation as the research objects,this paper deeply analyzes the principles,mathematical models,applicable conditions,accuracy and practical application effects of the two methods,and reveals their respective advantages and limitations.On this basis,comprehensive measures to reduce the loss of distribution network are put forward from the aspects of optimizing grid structure,reactive power compensation,automation construction and economic operation of transformers.The research results of this paper can provide important theoretical basis and practical guidance for distribution network planning and design,operation management and loss reduction and efficiency improvement,and have broad engineering application prospects.
