Distribution network planning whole-process evaluation system

Abstract

The invention discloses a distribution network planning whole-process evaluation system, and the system comprises a system management module used for the management of an organization, a system, a cache and a process, and setting an extraction tool. The system also comprises an extraction management module used for extracting business data according to an extraction tool and obtaining a business data mapping relationship, a modeling and visual analysis module used for evaluating a modeling tool and carrying out a data visualization process; and a distribution network planning evaluation moduleused for constructing a distribution network problem library evaluation strategy model, a distribution network project library evaluation strategy model and a distribution network project construction effect evaluation strategy model according to the modeling tool. According to the technical scheme, the management and control requirements are met according to distribution network planning; basedon multi-professional data integration distribution network service data, a distribution network planning problem library and a distribution network planning project calculation evaluation strategy are calculated, and thereafter, distribution network planning problems, distribution network planning projects and planning project construction effects can be evaluated, the whole process of distribution network planning is effectively evaluated, and the quality of distribution network planning is improved.

Description

technical field [0001] The present application relates to the technical field of electric power system, in particular to a system for evaluating the whole process of distribution network planning. Background technique [0002] At present, the distribution network planning problem database and project database of Yunnan Power Grid are manually constructed by the relevant personnel of the local and municipal units, and it is difficult for the urban planners to evaluate the authenticity of the basic data efficiently; the provincial companies, prefectural and municipal personnel carry out the review of the problem database and the planning project database When it is done manually, it is time-consuming and labor-intensive, and the actual power supply performance indicators (such as: three-phase unbalance, low voltage, heavy overload, line loss rate, etc.) Without guarantee, the quality of distribution network planning project library is reduced, and the distribution network plan...

AI Technical Summary

Problems solved by technology

[0002] At present, the distribution network planning problem database and project database of Yunnan power grid are manually constructed by the relevant personnel of various cities and units, and it is difficult for the city planners to efficiently evaluate the authenticity of the basic data; provincial companies, prefectural and municipal personnel carry out the review of the problem database and planning project database When it is done manually, it is time-consuming and labor-intensive, and the actual power supply performance indicators (such as: three-phase unbalance, low voltage, heavy overload, line loss rate, etc.) and power supply reliability indicators of the power grid cannot be used to carry out intelligent automatic evaluation. The quality of the distribution network planning project library is not guaranteed, thereby reducing the quality of the distribution network planning project library, which has a negative impact on the distribution network planning work

[0003] In addition, at the city level, some power supply bureaus have not carried out the evaluation of the construction effectiveness of planning projects, partly because of the lack of effective means, only qualitative analysis, the effect is not ideal

The whole process of planning supervision and inspection needs to be carried out manually, and there are problems such as data export and import difficulties, and quantitative evaluation of the problem database and planning project database.
