Line loss lean comprehensive management system and method

Abstract

The invention relates to a line loss lean comprehensive management system and a line loss lean comprehensive management method. Relevant line loss data dispersed at automation systems are integrated so as to establish a uniform line loss databank and eliminate line loss information isolated island. The data is read on line so as to calculate the line loss, and the conventional line loss calculation is changed into on-line statistics and calculation from afterwards statistics and calculation, so that the real-time property in line loss analysis is enhanced. The line loss situation of an electric power bureau is calculated in the overall angle, the calculation and analysis on the line loss cover all voltage grades of a power grid, and the comprehensiveness and the completeness in line loss calculation and analysis are ensured. By adopting the on-line calculation mode, the situation that in the past the calculation and analysis can only be carried out on typical days is changed, the line loss analysis does not change along with the change of the season and the external environment any longer, the calculation result is more accurate and real, the situation that in the past only the line loss result is singly and roughly analyzed is changed, the working cost is lowered, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a power system, in particular to a line loss lean comprehensive management system and a line loss lean comprehensive management method. Background technique [0002] Power grid power loss (referred to as line loss) is an important comprehensive technical and economic index for power companies, and it also reflects the planning and design, production technology and operation management level of the power grid. The power loss generated by the power grid during the transmission of electric energy directly affects the efficiency and economic benefits of electric power. With the deepening of power system reform, whether the operation of the power grid is economical, whether the technical means of power supply and consumption management are scientific, etc., all involve the operating costs of power grid enterprises and the overall economic benefits of the whole society. Therefore, reducing line loss is an important task for the powe...

AI Technical Summary

Problems solved by technology

[0004] (1). The data related to line loss is scattered in various automation systems, and there is a phenomenon of "information island"

[0005] (2). The calculation of the line loss is done after the statistics of each system, and then the data is sorted out. Therefore, it is a statistical calculation after the event, and online statistics and calculations cannot be performed in real time.

[0006] (3). The line loss calculation cannot cover all voltage levels of the power grid, and cannot guarantee the comprehensiveness and integrity of the line loss calculation

[0007] (4). Only typical days can be used for calculation and analysis

[0008] (5). The analysis of line loss results is relatively simple and rough

[0009] (6). Data summary is manual summary, high work cost and low work efficiency
