Establishment of distribution network engineering equipment model selection rule base

Abstract

The invention discloses establishment of a distribution network engineering equipment model selection rule base, comprising establishment of an engineering design parameter system base and establishment of an equipment model selection rule base. The invention can assist assessment experts in quickly, accurately and intelligently evaluating the rationality of engineering cost, innovate the assessment mode and improve the assessment efficiency. The invention solves the problems of uniform design assessment measure standards, large professional assessment workload and the like, greatly improves the efficiency and quality of distribution network engineering design assessment, and efficiently and accurately guides the perfection and investment control of distribution network engineering design schemes.

Description

technical field

[0001] The invention relates to the establishment of a type selection rule base for distribution network engineering equipment, which belongs to the field of power systems. Background technique

[0002] With the continuous deepening of power system reform and the sustained and rapid growth of the national economy, as the scale of investment increases, the impact of project cost levels on the development of power grids is becoming more and more significant, and the cost of power grid projects has therefore attracted much attention. The distribution network generally adopts closed-loop design and open-loop operation. The entire distribution network structure is huge and complex. Technical and economic experts generally evaluate it based on their own experience when analyzing the cost. There is a lack of a set of scientific, reasonable and effective evaluation standards, which cannot be very good. Controlling distribution network project investment in a certain ...

Embodiment Construction

[0015] The establishment of the distribution network engineering equipment selection rule base of the present invention includes the following contents:

[0016] （1） Establishment of Engineering Design Parameter System Database

[0017] Using the research results of the distribution network engineering design parameter system, a comprehensive and appropriate engineering design parameter auxiliary evaluation system database is established in the system to provide data comparison reference for design review. In the design parameter system library, different parameter items, standard values ​​or reference ranges are formulated for different project categories; multiple sets of parameter item system tables are allowed to be established according to different design schemes, and regular maintenance and management are supported by experts.
