Power grid line loss fine management method based on data mining

Abstract

The invention discloses a power grid line loss fine management method based on data mining, and the method comprises the steps of dividing an evaluation system into four dimensions: planning, management, operation and technology, and carrying out the whole line loss management process; according to an index selection principle, selecting indexes, constructing a multi-dimensional line loss management evaluation index system, solving dimensions and index weights, formulating index scoring standards according to various specifications and index data conditions of a power grid, and then constructing a prefecture-level power grid multi-dimensional line loss management evaluation system. According to the invention, an analytic hierarchy process is adopted to select evaluation indexes with commonality and practicability, and a hierarchical closed-loop management and control mechanism for line loss collection management, professional management and evaluation indexes is formed, so that differences of different professional dimensions between different management subjects and in the same subject can be effectively found, the problems that current prefecture-level power grid line loss management assessment is imperfect, and the current line loss management situation is difficult to assess are solved, and procedural, standardized and lean management of line loss is achieved.

Description

technical field [0001] The invention relates to a data mining-based refined management method for power grid line loss, belonging to the technical field of line loss management. Background technique [0002] The line loss rate is an important evaluation index for evaluating the structure, operation and management level of the power grid. If effective measures are not taken to reduce the loss in time, it will not only cause waste of electric energy, but may also threaten the safety and reliability of the power grid operation. At present, the traditional meter reading can only see the fluctuation of the line loss rate every month, and cannot display the power supply and sales in real time, making it difficult to find problems in the line loss management, and the line loss has no obvious role in monitoring and guiding the power grid. [0003] The traditional line loss management adopts the four-point line loss management standard. The four-point management considers the line l...

AI Technical Summary

Problems solved by technology

The four-point management considers the line loss from the four aspects of voltage division, partition, line distribution, and station area. Although there are many small line loss four-point indicators, the final assessment is still the line loss rate index.

It is unreasonable to simply use the line loss rate index as the evaluation standard, and it even conceals the

[0004] Some management factors behind the indicators cannot fully reflect the level of line loss management

At the same time, the traditional line loss management system is not strong, the coordination of various professional work is not high, and the support for line loss management is not enough, which increases the difficulty of loss reduction and energy saving.

In addition, there are still problems such as unreasonable grid structure, heavy overload, low voltage, and large line loss in the city-level power grids in various regions. The management is still weak, and the level of line loss management still needs to be improved.
