Embodiment Construction

[0040] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0041] In the embodiment of the present invention, by filtering the metering data obtained by the line loss basic application system, the metering data required after filtering is sent to the superior line loss management center, and the metering data that does not need to be sent is filtered out by this method, Therefore, the present invention prevents the bottleneck problem caused by concurrent data transmission of a large number of collection points, and reduces the storage capacity and calculation capacity of the superior line loss management center by preprocessing the metering data.

Abstract

The invention is applied to the line loss management field of a power system and provides a method for rapidly calculating and analyzing line loss. The rapid line loss analyzing method comprises the following steps: a hierarchical modeling is carried out on a power supply network; line loss calculation attributes are set for a relative power network object; line losses at each level are calculated individually; the superior line loss directly uses the calculation result of the inferior line loss. During the line loss calculation and analyzing process, the method fully utilizes the characteristics of hierarchical transmission and hierarchical management of the power network, effectively solves the problems of large data quantity and slow calculating process during the line loss calculation and provides technical support for managers of power companies to master line loss conditions fully and rapidly.

Description

technical field [0001] The invention belongs to the field of electric power management, in particular to a method and system for fast line loss analysis. Background technique [0002] In the power system, electricity first enters the high-voltage transmission network of the power company from the power plant. After long-distance transmission in the high-voltage transmission network, the transformer changes to the transmission network of the next level of voltage. After transmission, the transformer changes to a lower voltage transmission network. The transmission network of the first-level voltage will eventually enter the large users of each voltage level, or become a 220V civilian voltage and enter ordinary households. [0003] It can be seen from the above power transmission process that power transmission is a very complicated process. Not only is the transmission process complicated, but the power system also involves a complex management system. Different voltage leve...
