In view of the untrue of theoretical line loss calculation result

the owe cohesion between the statistical line loss and the theoretical line loss and the unscientific loss reduction decision-making problem

a scheme for development and application of theoretical calculation and analysis system for real-time line losses of power grid is put forward. The system design principle

the system architecture and the main functions of software are discussed. And also

the data structure and data flow are expounded in detail. The system has been successfully applied in the whole process of loss management in State Grid Hunan Electric Power Corporation which improves the level of loss management and provides strong technical support for the loss reduction efficiency.
