| There is a large number of distribution transformer in the grid,distribution transformer lossing a lot of power when it is operating,through the capacity of one distribution transformer is limited,the power loss of one distribution transformer is limited,because of the numerous,the total loss is very large.when distribution transformer is on economic operation,the power loss of distribution transformer is the fewest.So,realization of distribution transformer economic operation has special significance on energy conservation.In the paper,introduces the research background and significances of distribution transformer economic operation,introduces the current situation of research of distribution transformer economic operation,introduces the general situation of economy and society,the condition of grid,and the current situation of distribution transformer operation in Julu county,put forward to the existing problem of distribution transformer operation,and introduces the standard of construction of distribution transformer in Julu county.finally,on the basis of the current situation of the research of distribution transformer economic operation,based on the trend of economic and social development of Julu county,according to the specific situation of the distribution network load of Julu county,through the analysis of operation of distribution transformer of Julu county in the typical day,analyse the influence factors of distribution transformer economic operation,take measures which conform to distribution transformer economic operation of Julu county,and the measures base on five aspects which is model selection,selection of capacity and mode of operation,changing the condition of unbalanced operation,compensation of reactive power,management improvement.Put forward the measures which realize the economic operation:1.Analyse the influence factors of materials and technology for the distribution transformer economic operation,choose the energy-saving distribution transformer which is made by qualitative materials with better technology,replace the high loss distribution transformer with the energy-saving distribution transformer.2.According to this situation that the power load is not stable in Julu county,make two distribution transformer run in parallel,and to install the analysis equipments of distribution transformer economic operation for the two distribution transformer,the analysis equipments could monitor the load of distribution transformer,according to the size of load,it could adjust the mode of operation of the two distribution transformer automatically which make one transformer r un or make two transformer run in parallel,or using the adjustable capacity transformer,according to the load,we could adjust the capacity,so as to realize the goal of distribution transformer economic operation.3.Analyse the influence factors of the condition of unbalanced operation for distribution transformer economic operation,for the sake of changing the condition of unbalanced operation,replace three-phase transformer with single-phase transformer,or replace the Yyn0 transformer with the Dyn11.4.According to the current situation of compensation of reactive power in Julu,take the measures of compensation of reactive power to realize the goal of distribution transformer economic operation.5.Analyse the problem which is found in the management o f the distribution transformer of Julu county,take some measures such as reasonable planning and layout for distribution transformer,realize the goal that improve the level of management,realize the goal of distribution transformer economic operation buil t around the premise that we do not invest lots of funds... |
