Embodiment Construction

[0033] The technical solution of the present invention will be further specifically described below through a specific embodiment and accompanying drawings.

[0034] The investment decision-making method for 10KV and below distribution network projects based on the basic ledger includes the following steps:

[0035] 1. Establish an evaluation index system for 10KV and below distribution network

[0036] In this embodiment, the basic ledger data comes from the regional SCADA, PMS system, transportation inspection department, control center, dispatching system, power supply station, marketing department, etc., and separate statistics according to the line and station area, which can reflect the regional distribution more completely. operation of the network. Its line data type involves basic line information, line scale, network structure, load situation, power supply and sale, safe operation, etc.; its station area data type involves station area basic information, low-voltage...

Abstract

The invention relates to a distribution network project investment decision-making method, in particular, a basic machine account-based 10KV-or-below power distribution network project investment decision-making method. The method includes the following steps that: 1, a 10KV-or-below power distribution network evaluation index system is established; 2, a distribution network status analysis comprehensive evaluation model is established; 3, a problem list is established and correlated with the index system and projects; and 4, projects are sequenced, and decisions are made for the projects. According to the method of the invention, investment decisions are made for distribution network projects according to distribution network basic machine accounts; when the projects have not been put into use, the evaluation index system and the comprehensive evaluation model are established, and the problem list is determined according to distribution network development and status analysis results;the problem list is correlated with the index system and the projects, and therefore, the evaluation and sequencing of project improvement effects can be realized; data are reliable, evaluation results are more accurate; a quadratic membership degree function is used to normalize scores, so that the small changes and trends of indexes can be reflected; and the collection of distribution network basic machine account data is easy. The method has a bright promotion value and application prospect.

Description

technical field [0001] The invention relates to an investment decision-making method for a distribution network project, in particular to an investment decision-making method for a 10KV and below distribution network project based on a basic ledger. Background technique [0002] Distribution network project investment occupies an important position in the current power grid construction. How to reasonably evaluate the distribution network project investment and guide the distribution network construction and development is a major problem that power grid companies need to solve. As the end of the power grid structure, the 10KV and below distribution network directly distributes the electric energy delivered by the upper-level transmission system to the end users. Its safe and reliable operation will affect the power supply level of users, and have the most direct impact on the production and life of users. In recent years, the scale of demand for the construction and renovat...
