The method of calculation of statistics and network equipment based on online net loss net loss calculation of theoretical

The present invention belongs to the technical field of power grid system analysis and calculation of network losses, and more particularly, to statistical method for calculating net loss of network equipment based on online net loss calculation of the theoretical. The method comprising: establishing a pass line or mark transformer grid company under the jurisdiction of the grid range boundary, based on network topology structure of the automatic statistics and update participate in online Theoretical Loss Calculation of lines and transformers, which can calculate the distribution theory losses and calculating drop loss of decision-making. With this method only requires manual maintenance grid company under the jurisdiction of the border crossing lines or transformers, the device will automatically determine the participation of all losses calculation. The traditional way of manual maintenance workload greatly reduced compared to the way, and can automatically adapt to changes in the network structure and improve the power grid line loss calculation and theoretical net loss reduction and the availability and accuracy of decision-making.
