Line loss comprehensive-management benchmarking evaluating system and method for county-level power enterprises

Abstract

The invention relates to a line loss comprehensive-management benchmarking evaluating system and method for county-level power enterprises. The line loss comprehensive-management benchmarking evaluating method includes acquiring and managing power indicators of the county-level power enterprises, and setting up a county-level power enterprise model according to power level and power structure; scientifically and reasonably selecting evaluation indicators and weight relations by an AHP level analysis method, and setting up a county-level power enterprise line loss management and evaluation model from planning, managing, operating and technique; determining weights of dimension and indicators in the model by a Delphi method and devising objective indicator evaluation standard; constructing a line loss comprehensive-management evaluating system of the county-level power enterprises to evaluate line loss management multi-dimensional benchmarking and forming line loss centralized management, professional management and evaluation indicator grading closed-loop management mechanism. Accordingly, line loss lean management level is improved.

Description

technical field [0001] The invention belongs to the field of electric power system management evaluation, and specifically relates to a model and method of a power grid line loss management evaluation system and a model and method for classifying electric power enterprises. Background technique [0002] Line loss management is the core task of power grid enterprises to save energy and reduce emissions. It involves planning and construction, production, marketing, operation and other disciplines and departments, and has the characteristics of professionalism and comprehensive system. The traditional line loss management evaluation can be divided into two modes: line loss rate index benchmarking and four-point management standard evaluation, but the level of line loss rate is not completely consistent with the level of line loss management. Introducing benchmarking management and strengthening benchmarking analysis and assessment and evaluation will help solve the problem of "...

AI Technical Summary

Problems solved by technology

[0003] The traditional line loss rate index benchmarking model, in terms of line loss rate index benchmarking, due to the inherent factors of grid structure, equipment status, and power consumption structure in each region are different, the level of line loss rate and the level of line loss management are not complete unanimous

It is unreasonable to simply use the line loss rate index as the evaluation standard, and even cover up some management factors behind the index, which cannot fully reflect the level of line loss management, and the guiding role of actual management work is not obvious

The traditional four-point management standard evaluation mode involves four-point line loss basic data management, line loss four-point index management, line loss four-point analysis and line loss abnormal management, measurement and meter reading management, assessment management, and theoretical calculation of line loss The development status, the completion of sub-line and sub-station areas, the completion of line loss rate indicators, the application of new technology and management innovation are nine units, and the expert group on-site inspection and evaluation method is adopted. The evaluation process takes a lot of time and manpower, limited by the sampling data and The subjective influence of the inspectors is difficult to reflect the problems existing in the actual management, and it is also unable to effectively connect with the current power grid management profession
