Electric Distribution Network Theory Loss Calculation And Analysis Of LuoGang Area

Line loss theoretical calculation is a kind of important technical management tool for reduction energy saving, strengthen the line loss.Through theoretical calculation power loss can be found in power grid distribution rule through calculation and analysis to expose the management and technical problems, to reduce loss to provide theoretical and technical basis work, can make a loss reduction work focusing, improve energy loss reduction of benefit, make the line loss management more scientific.So in the grid construction and reform process and normal management should be regular line loss theoretical calculation. This paper discusses the theoretical calculation method of power line loss, analysis and the advantages and disadvantages of various methods for calculating analysis and comparison, combining with he actual situation of 10kV power system of LuoGang area, the most suitable method of the distribution network equivalent resistance method for the distribution theory loss calculation method is performed.This paper discussed the basic principle and method of calculating process.Combining with the 10kV power structure of LuoGang area, respectively hyper distribution transformer equivalent resistance and the entire network wiring equivalent resistance is carried out. Besides aiming to the difficult of distribution power loss calculation made by generating new energy technology such as small hydropower, small-scale, wind power, the equivalent resistance is performed.A few of the power supply for distribution network security demand higher ring network distribution network structure or ends power supply system, make understand nets instructions, namely select the "power point" ring net is decomposed into radial of kind of network loss calculationSelect line loss theoretical calculation on tipical day, take representative 24 strikes, combined with the measured data load distribution network consumers 10kV collected in advance equipment parameters and performance data of grid structure parameters as an example.Calculation results and actual measurement line loss comparison, it is concluded that the proportion of various losses, the calculated results comparison and analysis, found the main contradiction loss reduction, and puts forward Suggestions of loss reduction and the corresponding measures...
