The Theoretical Calculation And Reduction Solution Research On The Line Loss In The Township Power Supply Enterprises

Line loss refers to the total electric energy loss from the electric power transmissions in the power-supply enterprises operating in the power grid. It does not only relate to the economic benefits of a power-supply enterprise, but also is a key management factor that reflecting the level of the enterprise operation. To achieve more-supply-less-loss by taking the measures of reducing the line loss will save energy and increase the revenue of the power-supply enterprise. The causes of the line loss are diverse. So are the proportions of the component factors in the line loss in different regions. The cost of eliminating these factors can be rather different. Furthermore, some measures which should reduce line loss in theory are inapplicable in the practical situations. The key to effect the solution measures is the accuracy of the theoretical calculations. It will contribute to the quantitative analysis on the various factors that caused the line loss, the pre-evaluation on the effects of the measures and the investment decisions.However, the common-used softwares can only theoretically undertake the simplified calculations on the line loss, due to the basic ability of the data process and simple measure technology. The accuracy of this calculation can not meet the actual requirements. This paper will analyze the causes of inaccuracy and propose the improvement measures. Adjusting the input data appropriately while using the same software is to make the accuracy of the theoretical line loss calculation meet the requirements. The actual improvements on the accuracy will be examined according to the actual system parameters and operating data of Gujing Town Power Supply Station. Also, this paper will analyze the proportions of the component factors in the line loss and propose the improvement measures, subjected to the actual situations. The feasibility and effects of these measures will be examined by the comparison of the before-after data of the implementation. The procedures of reducing the line loss to be commonly used will be specially formulated upon the cost-effect ratio. It, significantly in theory and practice, will be able not only to reduce the line loss and the cost of power supply operations of the township power-supply enterprises, but also to improve the management level and the revenue of the power supply enterprises.
