Power system line loss management analysis method and system

Abstract

The invention discloses a power system line loss management analysis method and a power system line loss management analysis system. The power system line loss management analysis method comprises the step of analyzing map style-based display line loss and graphic style-based display line loss as well as virtual electricity loss generated by various statistical calibers. The power system line loss management analysis system comprises a map style-based display line loss module, a graphic style-based display line loss module and a virtual electricity analysis module. The method and the system have the benefits that through directly displaying the line loss situation by adopting the map style-based display line loss module and the graphic style-based display line loss module, the graphic input in a visual graphic interactive mode and a highly-efficient network structure are realized; and through analyzing the virtual electricity loss generated by the various statistical calibers, the effect caused by time difference is eliminated, and the difficulty in virtual electricity loss calculation of a power supply company is effectively solved.

Description

technical field [0001] The invention belongs to the field of electric power systems, and in particular relates to a method and system for line loss management and analysis of electric power systems. Background technique [0002] The line loss rate is an important technical and economic index for the country to assess the power company, and it is one of the main contents for the power company to complete the national plan and the enterprise level. At the same time, the line loss rate is a comprehensive reflection of the management level of the power company. Therefore, line loss calculation and management are of great significance to power systems. [0003] The prior art power system line loss management system usually describes the topological relationship between the monitoring points of the power grid with the attributes of each component in the database, and the analysis results of line losses at all levels are displayed in tabular form and output in the form of EXCEL rep...

Problems solved by technology

The line loss management system in the prior art does not provide an intuitive and graphical display method, does not provide automatic positioning analysis and alarm functions, the system is not highly automated, the operation is cumbersome, and the use efficiency is low

[0004] In addition, the power supply company usually issues a monthly line loss statistical report at the end of the month. The current line loss management system of the power system can only support one assessment and statistics day per month, such as the 31st. , the power loss has a great impact on the statistical line loss rate; however, due to the management needs of the power supply company, it is necessary to report the analysis results of the line loss calculated by meter reading for the same period of the supply and sale of electricity on the 25th of each month. At this time, the line loss management system does not have a complete system Data and the corresponding data model to support, so it brings a lot of inconvenience
