Abstract

The invention relates to an optimal wire-connection mode automatic selecting platform for a power distribution network based on economy and reliability. The optimal wire-connection mode automatic selecting platform is characterized by comprising an input module, an analysis module, a comprehensive evaluation module, an output module and a database module. The input module is respectively connected with the analysis module, the comprehensive evaluation module and the database module, and the analysis module, the comprehensive evaluation module and the output module are connected in sequence. The analysis module analyzes data input by the input module, calculates and sends economic data, reliable data, voltage quality constraint impact factors and short-circuit current constraint impact factors in a feasible wire-connection mode to the comprehensive evaluation module, the comprehensive evaluation module obtains comprehensive evaluation results and qualitative analysis results of the wire-connection mode according to received data and automatically selects an optimal wire-connection mode according to the comprehensive evaluation results, and the output module outputs the optimal wire-connection mode. Compared with the prior art, the optimal wire-connection mode automatic selecting platform for the power distribution network based on the economy and the reliability has the advantages of being high in efficiency and strong in integration, being tightly combined with project actual conditions and the like.

Description

technical field [0001] The invention relates to a system for selecting a wiring mode of a distribution network, in particular to a platform for automatically selecting an optimal wiring mode of a distribution network based on economy and reliability. Background technique [0002] With the increasing awareness of the demand and value of power supply reliability in society, power companies have continuously increased their requirements for power supply reliability, and my country's power industry has paid more and more attention to the reliability of power supply and related economic issues. [0003] At present, in the process of optimal planning, most distribution network researches only use radiation constraints as the topological requirements of distribution network planning, without taking the wiring mode into consideration, which cannot meet the needs of practical applications. For the distribution network, the choice of connection mode is particularly important. It not o...
