With the rapid growth of China's socio-economic development and continuous power reform, the power industry has shown a good and rapid development trend. Although significant progress has been made in equipment upgrading and transformation of development modes, the contradiction between power supply and demand still exists due to issues such as uneven economic development and resource distribution. Therefore, energy conservation and loss reduction are widely recognized as important measures to solve the energy supply contradiction and an important way to improve the quality and efficiency of economic growth.

Line loss rate is an important economic and technical indicator in the power industry, reflecting the degree of energy loss during power transmission in the power grid. The calculation of managing line loss is mainly affected by factors such as different periods of supply and sales electricity statistical time, meter reading errors, and electricity theft by customers. Among them, the different periods of supply and sales electricity statistical time have a serious impact on the accuracy of line loss rate. To more accurately reflect the true loss situation of the power grid, it is not necessarily the best choice to only consider managing line loss data. One solution to this problem is to use the same period line loss rate statistical calculation. In modern power grid companies with full coverage of electricity meter collection and topological data information, the same period line loss rate statistical calculation has become the best method to avoid the impact of different periods and is widely used in power grid management.

This article reviews the current research status and development trends of domestic and foreign line loss management and same period line loss management, laying a foundation for subsequent research work. Then, the factors that cause line loss are discussed in depth, and various line loss management methods are compared. Finally, the conclusion is drawn that same period line loss management has advantages. Based on the current operation status of the State Grid Corporation's power software, this article proposes a feasible system integration requirement plan to achieve same period line loss management. On this basis, this article designs a same period line loss calculation model and explores the principles, ideas, and practical methods of same period line loss analysis from the perspectives of traditional line loss analysis and line loss business analysis. Finally, this article designs three sets of same period line loss-related evaluation and assessment indicators for different periods of Daxing Power Supply Company to adapt to the evaluation needs of different periods, improve the same period line loss index management mechanism, and effectively support power grid enterprises to carry out same period line loss management work.
