Investigation On The Loss Reduction And Efficiency Improvement For Power Supply Companies

With the continuous development of society, demand for energy continues to rise. Electricenergy as the main energy source of human social activities, its energy-saving measures arediscussed and studied. It is conducive to the promotion of the economic efficiency of enterprises,the overall development of human and the whole society’s harmony. At present, the demand ofthe electric energy in China exceeds the supply and improving the utilization rate of electricenergy and reducing the power loss have become the development direction of energy-savingpolicy. Meanwhile the state policy also clearly points out the directions and ideas for energysaving. Especially the significance of energy saving in power supply companies is greater.Given this background, firstly the basic concept and components of power loss areintroduced. Secondly the calculation methods of power loss are introduced, including calculationmethods of grid loss, distribution network loss and low-voltage network loss and so on. Throughanalyzing the theory of grid power loss calculation method, the calculation of the RMS currentand average current and the calculation of power loss rate, the reasons and components of powerloss are specifically explained.Then in view of the energy-saving management methods and loss reduction plan in powersupply companies and combined with the actual situation of the power supply, the energy savingin two aspects of technology and management are presented. Starting with strengtheningmanagement, strengthen the intensity of management loss and technology loss, and theeconomic operation level can gain a further improvement. The management level of power lossin the power supply companies is also improved. Finally through the benefit analysis of energysaving and loss reduction, the significance of loss reduction and the importance and necessity forthis research work are demonstrated.
