Line loss control system

Abstract

The invention belongs to the field of power systems and automation, and particularly relates to a line loss control system. The system comprises a data acquisition unit, a processing control unit and an output display unit, wherein the acquisition unit is used for acquiring basic data for line loss computation, and the basic data comprise device parameter information, device state data, measured data, state estimation data and electric quantity data; the processing control unit is used for receiving the basic data acquired by the acquisition unit, and carrying out online computation and result analysis on load tests, line loss, network loss and the like; and the output display unit is used for receiving and displaying computation and result data of the processing control unit. The line loss control system can be used for implementing multi-dimensional network loss management, normalized load tests, and multi-dimensional online statistical line loss rate and theoretical line loss rate analyzing and monitoring reflecting the effects of changes of a grid framework, a load level, an operation mode and the like on electric transmission and transformation equipment and line los in time, and provide data support for economic operation and management of a power grid.

Description

technical field [0001] The invention belongs to the field of electric power system and automation, and in particular relates to a line loss control system. Background technique [0002] The calculation of power grid power loss includes calculation of statistical line loss rate and calculation of theoretical line loss rate. The statistical line loss rate is the line loss rate obtained from the statistics of the electricity supply and sales meters of the power grid within the jurisdiction of each network, province, and city power supply company; the theoretical line loss rate is the line loss rate of each network, provincial, and regional power supply company. The line loss rate calculated by the affiliated transmission, transformation, and distribution equipment based on equipment parameters, load flow, and characteristics. The power loss rate of power grid (also known as line loss rate) is an important economic and technical index that comprehensively reflects the level of ...

Problems solved by technology

[0003] A small number of power companies in China have carried out online evaluation research on power grid power loss, and established a calculation and analysis method for power grid online power loss based on the grid dispatching automation system and power collection system, but it cannot be seamlessly connected with the existing dispatching system. The calculation method Single, no multi-dimensional comparison of multiple calculation methods, large manual maintenance of equipment parameter collection points, untimely data extraction, and inaccurate calculation results without data verification, and online calculations cannot be performed, and grid power cannot be reflected in time Changes in loss

In addition, the actual load measurement and theoretical calculation of line loss in the regional power grid cannot be carried out normally, and the requirements for refined economic operation and management of the power grid cannot be met.
